Is Phoenix Guardian R Pro Hepa Air Scrubber 500 CFM Worth It?
Product Overview
The Phoenix Guardian R Pro is a professional-grade HEPA air scrubber that offers industrial-strength air purification in a relatively compact package. It’s engineered specifically for restoration professionals, contractors, and property owners dealing with serious air quality issues like mold remediation, fire damage restoration, or construction dust control.
First impressions reveal solid build quality with durable metal housing designed to withstand jobsite conditions. The unit feels substantial but remains maneuverable with its built-in wheels and handle. The control panel is straightforward with multiple fan speed settings that allow users to balance between maximum airflow and noise considerations.
How It Works
The Guardian R Pro employs a multi-stage filtration process to progressively clean air. First, air passes through a pre-filter that captures larger particles like dust and debris, protecting the more expensive HEPA filter from premature clogging.
Next, the air moves through the true HEPA filter which removes 99.97% of particles as small as 0.3 microns – including mold spores, fine dust, and most bacteria. This level of filtration significantly outperforms standard air purifiers found in most homes.
What sets this unit apart from commercial HEPA air scrubbers like the Mounto HEPA500 is its variable speed control that allows for precise airflow adjustment between 250-500 CFM, maximizing efficiency for the specific space and contaminant level.
The unit can function in two modes: as an air scrubber that purifies and recirculates air within a space, or as a negative air machine when ducted to create controlled airflow that prevents cross-contamination during remediation projects.
Safety & Certifications
The Phoenix Guardian R Pro meets stringent safety standards for professional use. Unlike some competing models, it produces zero ozone, making it safe for continuous operation in occupied spaces. This is particularly important for sensitive individuals with respiratory conditions.
The unit complies with EPA guidelines for air cleaning devices and features UL-listed components. Its HEPA filter meets the industry standard for true HEPA performance (99.97% efficiency at 0.3 microns).

Real-World Performance
In practical applications, the Guardian R Pro demonstrates impressive capability across various contaminants. For mold remediation, it effectively captures airborne spores, with restoration professionals reporting significant reduction in air sample counts after deployment.
For dust control during renovations, the unit can clean approximately 1,000-1,500 square feet effectively, though multiple units are recommended for larger spaces or heavier contamination. At maximum capacity, it processes 500 cubic feet of air per minute (CFM), allowing it to perform about 4 complete air changes per hour in a 1,500 square foot space with standard 8-foot ceilings.
While effective against allergens, pollen, and most bacteria, it’s important to note the Guardian R Pro does not incorporate UV-C or activated carbon technology in its standard configuration. This means it may be less effective against certain viruses and gaseous pollutants like VOCs without additional filtration accessories.
Installation & Maintenance
The Phoenix Guardian R Pro is designed as a standalone portable unit rather than an HVAC integration system. This provides flexibility for targeted air cleaning where needed most. No permanent installation is required – simply place the unit, plug it in, and power it on.
For negative air applications, the unit features a 12-inch outlet for attaching ducting to direct filtered air outside or to another area. Setup is straightforward enough for DIY users, though professionals may better understand optimal placement for specific remediation scenarios.
Maintenance centers primarily around filter changes. The pre-filter should be checked regularly and replaced when visibly dirty, typically every 1-3 months under normal use. The HEPA filter typically lasts 6-12 months depending on contamination levels and usage hours. No tools are required for filter changes, making maintenance relatively simple.
Cost & Value
With a price point of approximately $1,100-$1,400, the Phoenix Guardian R Pro represents a significant investment compared to consumer-grade air purifiers. However, when compared to other industrial-grade HEPA air scrubbers with similar specifications, the pricing is competitive.
Operating costs include electricity (approximately 1.9 amps on high setting) and replacement filters. Pre-filters cost around $15-20 each, while HEPA filters run approximately $150-200 with recommended replacement every 6-12 months for regular use.
| Cost Consideration | Phoenix Guardian R Pro | Consumer HEPA Purifier | Comparable Commercial Scrubber |

The Phoenix Guardian R Pro Hepa air scrubber 500 CFM delivers on its promise of professional-grade air purification. It’s ideal for restoration contractors, remediation specialists, and property managers dealing with severe air quality issues such as mold remediation, water damage restoration, or construction dust control.
Those seeking a solution for everyday residential air quality concerns would likely find better value in consumer-grade air purifiers. Similarly, homeowners with limited space or those needing primarily odor control might prefer compact units with activated carbon filtration.
The Guardian R Pro represents a significant investment, but for professionals and those facing serious air quality challenges, its durability, performance, and versatility justify the premium price point. When clean air is critical rather than just preferable, this unit delivers commercial-grade results.
Does the Phoenix Guardian R Pro Hepa air scrubber 500 CFM actually eliminate strong cooking odors like fish or burnt food?
The Phoenix Guardian R Pro has limited effectiveness against strong cooking odors like fish or burnt food in its standard configuration. This is because the unit primarily focuses on particle filtration through its HEPA system, which excels at removing solid contaminants but isn’t specifically designed for odor elimination.
The standard Guardian R Pro doesn’t include substantial activated carbon filtration, which is the primary technology for adsorbing gaseous pollutants and odors. While the pre-filter may have minimal odor-reducing capabilities, it’s insufficient for persistent strong cooking smells.
For cooking odor removal, you would need to purchase optional activated carbon filters or carbon pre-filters compatible with the Guardian R Pro. These accessories can significantly improve odor control capabilities but represent an additional cost and maintenance requirement.
In real-world applications, users report that with the optional carbon filtration in place, the unit can reduce cooking odors noticeably but may not completely eliminate particularly strong smells like fish or burnt food without sufficient runtime. Multiple air changes are typically needed for substantial odor reduction.
How often do the HEPA and carbon pre-filters need to be replaced under normal residential use in the Phoenix Guardian R Pro?
Under normal residential use, the filter replacement schedule for the Phoenix Guardian R Pro varies based on air quality conditions and usage patterns:
The pre-filter typically requires replacement every 1-3 months. This filter captures larger particles and protects the main HEPA filter from premature clogging. In environments with higher dust levels or pet hair, you might need to replace it closer to the 1-month mark.
The primary HEPA filter generally lasts 6-12 months under normal residential conditions. This longer lifespan reflects the protection provided by the pre-filter and the substantial capacity of the commercial-grade HEPA media.
Optional carbon filters or carbon pre-filters (if used for odor control) typically need replacement every 3-6 months, as carbon becomes saturated with adsorbed gases and loses effectiveness over time.
| Filter Type | Replacement Frequency (Residential) | Indicators For Replacement |
|---|---|---|
| Pre-filter | 1-3 months | Visible dust accumulation, darkening of filter material |
| HEPA Filter | 6-12 months | Reduced airflow, unit working harder at same setting |
| Optional Carbon Filter | 3-6 months | Diminished odor control effectiveness |
These timeframes can vary significantly based on your specific environment. Homes with pets, smokers, or near construction sites will require more frequent changes. The unit doesn’t feature electronic filter life indicators, so visual inspection and airflow performance are the primary methods to determine when replacement is needed.
Is the 500 CFM rating on the Phoenix Guardian R Pro sufficient to effectively clean the air in a 1200 sq ft open-concept living area?
The 500 CFM rating of the Phoenix Guardian R Pro is generally sufficient for effectively cleaning the air in a 1200 sq ft open-concept living area, but with some important considerations regarding air exchange rates and contaminant levels.
For residential air purification, industry standards recommend 4-6 complete air changes per hour (ACH) for effective air cleaning. In a 1200 sq ft space with standard 8-foot ceilings, the total air volume is approximately 9,600 cubic feet. At 500 CFM, the Guardian R Pro can process 30,000 cubic feet per hour, theoretically providing about 3.1 air changes per hour in this space.
This air exchange rate approaches the lower end of professional recommendations, making it adequate for general air quality maintenance in a 1200 sq ft open concept area with normal contaminant levels. The open-concept layout actually works in your favor, as there are fewer walls to impede airflow and create stagnant pockets.
However, for scenarios involving higher contamination (like renovation dust, heavy pollen seasons, or smoke remediation), the unit might be slightly undersized for this square footage. In these cases, you might consider supplementing with a second air purifier or accepting a longer timeframe to achieve desired air quality.
Strategic placement becomes crucial in larger spaces – positioning the unit centrally with unobstructed airflow will maximize its effectiveness. Running the unit on its highest setting during initial cleaning, then reducing to a lower maintenance setting once air quality improves, can optimize both performance and energy use.
Can the Phoenix Guardian R Pro be installed directly into an existing HVAC duct system, or is it a standalone unit?
The Phoenix Guardian R Pro is primarily designed as a standalone portable air scrubber rather than an HVAC integration unit. It’s not intended for permanent installation within existing HVAC ductwork for several important reasons:
First, the Guardian R Pro operates as an independent system with its own blower motor and controls. It’s engineered to function as either a freestanding air scrubber (drawing in and filtering room air) or as a negative air machine when properly ducted for specific applications like containment areas.
While the unit has a 12-inch outlet that can accept ducting, this feature is intended for temporary setups like venting filtered air outside during remediation work or directing clean air to specific areas. It’s not designed for the static pressure conditions of a whole-home HVAC system.
For those seeking HVAC integration, whole-house air purification systems specifically designed for in-duct installation would be more appropriate. These systems are engineered to work with the existing HVAC airflow and don’t impede normal system operation.
The Guardian R Pro’s greatest strength lies in its portability and ability to be deployed exactly where needed for targeted air cleaning. It can be moved from room to room or project to project, providing flexible air quality management that fixed HVAC systems cannot offer.
What is the noise level in decibels when the Phoenix Guardian R Pro is running on its highest setting?
The Phoenix Guardian R Pro operates at approximately 72-75 decibels when running on its highest fan speed setting. This noise level is comparable to the sound of a vacuum cleaner or busy traffic from inside a car.
At medium speed settings, the noise level drops to around 65-68 decibels, which is similar to normal conversation or background music. The lowest speed setting produces approximately 58-62 decibels, comparable to moderate rainfall or ambient office noise.
| Speed Setting | Approximate Decibel Level | Comparable Sound |
|---|---|---|
| High (500 CFM) | 72-75 dB | Vacuum cleaner, busy traffic |
| Medium | 65-68 dB | Normal conversation, background music |
| Low | 58-62 dB | Moderate rainfall, quiet office |
It’s worth noting that the Guardian R Pro is designed primarily as a professional remediation tool rather than a consumer air purifier, so noise reduction wasn’t the primary design focus. The unit prioritizes airflow volume and filtration efficiency over quiet operation.
For residential applications where the unit will operate in living spaces, most users find the medium or low settings provide a reasonable balance between noise tolerance and air cleaning performance for everyday use. The high setting, while noisier, might be reserved for unoccupied spaces or when maximum air cleaning is temporarily needed.
Does the UV-C light in the Phoenix Guardian R Pro generate any ozone, and is it safe for people with asthma?
The standard Phoenix Guardian R Pro HEPA air scrubber does not come equipped with a UV-C light in its base configuration. This is an important clarification as it directly impacts both the ozone question and asthma safety concerns.
As manufactured, the Guardian R Pro operates with zero ozone emission because it relies purely on mechanical filtration through its pre-filter and HEPA filter system. This absence of UV-C technology or ionization in the standard model means it produces no ozone as a byproduct of operation, making it safe for people with asthma or other respiratory sensitivities.
For asthma sufferers, the Guardian R Pro’s true HEPA filtration actually provides significant benefits by removing airborne triggers like dust mites, pet dander, pollen, and mold spores at a 99.97% efficiency for particles as small as 0.3 microns. The lack of ozone production further ensures the unit won’t create respiratory irritation.
It’s important to note that Phoenix does offer UV-C light kits as optional accessories for some of their air purification systems. If such an accessory were added, proper shielding would still prevent significant ozone production, but the standard Guardian R Pro as shipped does not include UV technology.
How much electricity does the Phoenix Guardian R Pro 500 CFM model consume per month with continuous operation?
The Phoenix Guardian R Pro 500 CFM model has an electrical draw of approximately 1.9 amps on its highest setting, which translates to about 228 watts of power consumption (based on standard 120V power). This relatively modest power usage for an industrial-grade air scrubber contributes to reasonable operating costs despite continuous use.
For continuous operation on high speed, the monthly electricity consumption would be approximately:
228 watts × 24 hours × 30 days = 164,160 watt-hours or 164.16 kilowatt-hours (kWh)
With the U.S. average electricity cost of about $0.15 per kWh (though this varies by location), continuous operation would result in approximately $24.62 in monthly electricity costs at maximum speed.
However, most users don’t run the unit continuously at maximum speed. The medium and low settings consume less power:
| Speed Setting | Approximate Power Draw | Monthly kWh (Continuous) | Est. Monthly Cost ($0.15/kWh) |
|---|---|---|---|
| High (500 CFM) | 228 watts | 164.16 kWh | $24.62 |
| Medium | 180 watts | 129.60 kWh | $19.44 |
| Low | 120 watts | 86.40 kWh | $12.96 |
For typical residential use with a mix of settings and perhaps 12 hours of operation per day, the actual monthly cost would be approximately $7-12, making it reasonably energy-efficient compared to many other professional-grade air quality systems of similar capacity.
Is the Phoenix Guardian R Pro effective at removing VOC fumes from a home after painting or new furniture installation?
The Phoenix Guardian R Pro has limited effectiveness against Volatile Organic Compounds (VOCs) in its standard configuration. The unit’s primary filtration technology is HEPA, which excels at capturing particulate matter but does not adequately address gaseous pollutants like VOCs emitted from fresh paint, new furniture, or building materials.
HEPA filtration alone cannot capture VOC molecules, which are much smaller than the 0.3-micron particles HEPA filters are designed to trap. VOCs exist in gaseous form rather than as solid particulates, requiring different filtration technology for effective removal.
For VOC removal, activated carbon filtration is the most effective approach. The standard Guardian R Pro doesn’t include a substantial activated carbon component in its base configuration. Phoenix does offer optional carbon pre-filters or carbon filter kits that can be purchased separately to enhance VOC removal capabilities.
With the optional carbon filtration installed, the unit becomes moderately effective at reducing VOCs, though still not as specialized as systems specifically designed for chemical and gas filtration. The effectiveness depends greatly on:
- The amount/quality of carbon media in the optional filter
- The specific VOCs present (some bind more readily to carbon than others)
- The concentration of VOCs in the environment
- The duration of operation
For significant VOC issues like post-renovation odors or new building materials, the Guardian R Pro with carbon filtration would be helpful but might need to be supplemented with additional ventilation or dedicated VOC air purifiers for optimal results.
What are the exact dimensions and weight of the Phoenix Guardian R Pro, and does it require a dedicated electrical circuit?
The Phoenix Guardian R Pro has the following exact physical specifications:
Dimensions: 22 inches high × 24 inches long × 14 inches wide (H × L × W)
Weight: Approximately 53 pounds when fully assembled with filters installed
These dimensions make it compact enough to fit in most spaces while still providing commercial-grade air cleaning capacity. The unit includes built-in wheels and a handle for improved mobility despite its substantial weight.
Regarding electrical requirements, the Guardian R Pro does not necessarily require a dedicated circuit for standard operation. It runs on standard 115V/60Hz power with the following electrical specifications:
- Amperage draw: 1.9 amps on highest setting
- Power consumption: Approximately 228 watts at maximum speed
- Standard grounded 3-prong plug connection
This power draw is well within the capacity of a standard 15-amp residential circuit. However, for best practices and to prevent nuisance tripping, consider these guidelines:
- Avoid placing the unit on circuits already heavily loaded with other high-draw appliances
- If running multiple air scrubbers, distribute them across different circuits
- For professional restoration settings where multiple pieces of equipment operate simultaneously (dehumidifiers, air movers, etc.), circuit planning becomes more critical
The relatively modest power requirements contribute to the unit’s versatility, allowing it to be deployed in various residential and commercial settings without special electrical accommodations in most cases.
For pet dander and allergens, how does the performance of the Phoenix Guardian R Pro compare to a standard portable HEPA air purifier?
When comparing the Phoenix Guardian R Pro to standard portable HEPA air purifiers specifically for pet dander and allergen removal, several key performance differences become apparent:
The Guardian R Pro offers substantially higher airflow at 500 CFM (cubic feet per minute) compared to typical consumer HEPA purifiers that range from 100-300 CFM. This higher capacity allows it to process more air more quickly, achieving faster allergen reduction in larger spaces.
Both use true HEPA filtration (capturing 99.97% of particles at 0.3 microns), but the Guardian R Pro typically has a much larger filter surface area. This increased media area allows it to capture more allergens before experiencing reduced airflow, resulting in more consistent performance between filter changes.
The commercial-grade construction of the Guardian R Pro includes superior sealing that prevents air bypass around filters, ensuring virtually all air is properly filtered. Some consumer units may have design compromises that allow small amounts of unfiltered air to bypass the filtration system.
| Feature | Phoenix Guardian R Pro | Typical Consumer HEPA Purifier |
|---|---|---|
| Airflow Capacity | 500 CFM | 100-300 CFM |
| Recommended Room Size | Up to 1,500 sq ft | 300-800 sq ft |
| Filter Capacity | Commercial-grade, high capacity | Residential-grade, smaller capacity |
| Noise Level (High) | 72-75 dB (louder) | 50-65 dB (quieter) |
| Price Point | $1,100-$1,400 | $200-$500 |
For households with severe allergies, multiple pets, or larger open spaces, the Guardian R Pro provides superior performance due to its higher capacity and commercial design. However, for average-sized bedrooms or apartments with mild to moderate pet allergen concerns, a quality consumer HEPA purifier may offer adequate performance at a significantly lower price point with the added benefits of quieter operation and more attractive design.
Are replacement HEPA filters for the Phoenix Guardian R Pro readily available, and what is their average cost?
Replacement HEPA filters for the Phoenix Guardian R Pro are readily available through multiple purchasing channels, though they represent a significant maintenance cost that should be factored into ownership considerations.
The primary sources for genuine Phoenix replacement filters include:
- Authorized Phoenix distributors and restoration equipment suppliers
- Online restoration equipment retailers
- Some specialized HVAC and air quality service providers
- Direct from manufacturer or manufacturer’s official online store
Cost structure for replacement filters breaks down as follows:
- HEPA Filter: $150-$200 per filter (replacement typically recommended every 6-12 months)
- Pre-filter: $15-$25 per filter (replacement typically recommended every 1-3 months)
- Optional Carbon Pre-filter: $30-$45 (if using for odor control, replacement every 3-6 months)
Annual filter costs for standard operation would therefore range from approximately $200-$350 depending on usage patterns and contamination levels. This represents a significant portion of the total ownership cost, though it’s comparable to other commercial-grade air filtration systems.
It’s worth noting that aftermarket compatible filters are sometimes available at lower price points, though these may vary in quality and exact fit compared to OEM filters. Using non-OEM filters could potentially affect performance or warranty status.
Can the Phoenix Guardian R Pro be used in a damp environment like a basement to help with musty smells and mold spores?
The Phoenix Guardian R Pro is exceptionally well-suited for use in damp environments like basements for controlling musty smells and airborne mold spores. In fact, water damage restoration and mold remediation are among the primary applications for which this commercial unit was designed.
The Guardian R Pro’s construction features durable metal housing and electrical components designed to withstand challenging environmental conditions. While not rated for extreme moisture exposure, it handles the elevated humidity levels typically found in basements without issue.
For mold spore control specifically, the unit excels due to its true HEPA filtration that captures 99.97% of particles as small as 0.3 microns – which includes most mold spores (typically 1-20 microns in size). This high-efficiency filtration can significantly reduce airborne mold concentration when operated continuously.
For addressing musty odors, the standard configuration offers limited effectiveness since HEPA alone doesn’t target gaseous odors. However, adding the optional activated carbon pre-filter significantly enhances odor control capabilities, adsorbing the microbial volatile organic compounds (MVOCs) that cause musty basement smells.
Important considerations for basement use include:
- Placing the unit away from direct water contact or extreme condensation
- Ensuring proper drainage in the basement to address the underlying moisture source
- Understanding that air filtration supplements but doesn’t replace proper moisture control
- More frequent filter changes may be necessary in high-humidity environments
For serious mold remediation projects, the unit can be configured as a negative air machine by ducting the exhaust, creating controlled airflow that prevents cross-contamination to other areas of the home during cleanup.
How do you know when the filters in the Phoenix Guardian R Pro need to be changed? Are there indicator lights?
The Phoenix Guardian R Pro does not feature electronic filter life indicators or warning lights to signal when filters require changing. Instead, it relies on more traditional methods for determining filter replacement timing:
Visual inspection is the primary method for the pre-filter. When the pre-filter appears visibly dirty, darkened, or clogged with dust and debris, it’s time for replacement. This typically occurs every 1-3 months depending on air quality conditions.
For the main HEPA filter, performance monitoring is the key indicator. When you notice reduced airflow or the unit seems to be working harder (motor sounds strained) to maintain the same air output, this suggests the HEPA filter is becoming restricted. Under normal use, this typically occurs after 6-12 months.
Time-based scheduling is another approach recommended by the manufacturer. Phoenix suggests replacing the HEPA filter annually for standard applications, or more frequently for heavy-duty usage or severely contaminated environments.
Professional users often employ differential pressure gauges that measure the pressure drop across filters to precisely determine replacement timing, though this is less common in residential applications.
While the lack of electronic indicators might seem like a limitation compared to some consumer air purifiers, this mechanical approach is common in commercial equipment and contributes to the unit’s durability by eliminating potential electronic failure points. The system’s straightforward design makes visual and performance-based assessment relatively reliable for determining filter condition.
What kind of maintenance, besides filter changes, does the Phoenix Guardian R Pro require, such as cleaning the UV bulb or interior?
The Phoenix Guardian R Pro requires minimal maintenance beyond filter changes, which is one of its advantages as a commercial-grade system. The unit’s straightforward mechanical design eliminates many potential maintenance points found in more complex air purification systems.
First, it’s important to note that the standard Guardian R Pro does not include a UV bulb in its base configuration, so there is no UV maintenance required unless you’ve added an optional UV kit. If such an accessory were installed, the UV bulb would typically require cleaning every 3-6 months and replacement annually.
The primary maintenance tasks beyond filter replacement include:
- External housing cleaning: Wipe down the exterior with a damp cloth as needed to remove dust accumulation. This is purely aesthetic and doesn’t affect performance.
- Intake grill inspection: Periodically check for and remove any large debris that might restrict airflow through the intake grill.
- Internal chamber inspection: Once or twice yearly, with the unit unplugged and filters removed, visually inspect the internal chamber for dust accumulation and clean if necessary with a vacuum and damp cloth.
- Wheel and handle maintenance: Ensure wheels roll freely and the handle functions properly for mobility.
- Cord inspection: Periodically check the power cord for any signs of wear or damage.
The fan motor is permanently lubricated and sealed, requiring no maintenance under normal conditions. There are no belts to adjust or replace, and the electrical components are designed for long-term reliability without intervention.
This minimal maintenance profile is one of the key advantages of the Guardian R Pro, particularly for users who value simplicity and reliability. The focus on mechanical filtration rather than complex electronic or UV systems reduces both maintenance requirements and potential failure points.
Is the Phoenix Guardian R Pro certified by CARB for ozone emissions, especially since it includes an ionizer?
The Phoenix Guardian R Pro does not include an ionizer in its standard configuration, which is an important clarification regarding potential ozone concerns. The base model relies solely on mechanical filtration through its pre-filter and HEPA filter system without any ionization technology.
Due to the absence of ionization technology in the standard model, the unit produces zero ozone during normal operation. This makes it compliant with California Air Resources Board (CARB) regulations regarding ozone emissions from air cleaning devices, which limit ozone production to less than 0.05 parts per million.
It’s worth noting that there may be some confusion in the marketplace because:
- Some retailers or marketing materials might incorrectly list ionization as a feature
- Phoenix offers other models that do include ionization technology
- Third-party ionization accessories are available that can be used with various air scrubbers
If you’re specifically concerned about ozone sensitivity (for asthma sufferers or other respiratory conditions), the standard Phoenix Guardian R Pro is an appropriate choice precisely because it avoids ionization technology in favor of proven mechanical HEPA filtration that produces no ozone byproducts.
For verification, the product’s technical specifications and operation manual confirm that the standard configuration relies on physical filtration rather than electronic air cleaning methods that might generate ozone.
What is the warranty period for the Phoenix Guardian R Pro, and does it cover both parts and labor for installation?
The Phoenix Guardian R Pro comes with a comprehensive warranty package that reflects its position as a professional-grade air cleaning device. The standard warranty includes:
A one-year limited warranty covering defects in materials and workmanship under normal use conditions. This covers the entire unit including the housing, motor, fan, electrical components, and control systems.
The warranty specifically covers replacement parts and factory labor for repairs. However, it’s important to note that since the Guardian R Pro is a portable standalone unit rather than a permanently installed system, there is no “installation labor” component to the warranty.
Consumable items like filters are explicitly excluded from warranty coverage, as these are considered normal maintenance items that require regular replacement regardless of unit condition.
For warranty service, Phoenix requires:
- Proof of purchase with date (keep your receipt or invoice)
- The unit’s serial number
- Description of the issue
- Return authorization before shipping any unit for service
For commercial users who purchase multiple units, Phoenix sometimes offers extended warranty options or service contracts, though these vary by region and distributor.
The warranty does not cover damage from misuse, improper maintenance, unauthorized modifications, or operating the unit outside its intended environmental parameters. Transportation costs to return the unit for warranty service are typically the responsibility of the customer.
How does the 500 CFM air scrubber perform on smoke removal after a small kitchen fire?
The Phoenix Guardian R Pro 500 CFM air scrubber demonstrates strong but specialized performance when addressing smoke contamination after a small kitchen fire. Its effectiveness varies depending on the smoke components being targeted.
For particulate smoke components (the visible smoke particles), the Guardian R Pro excels due to its true HEPA filtration. The HEPA filter captures 99.97% of particles as small as 0.3 microns, which includes most smoke particulates. This capability allows the unit to effectively clear visible smoke and reduce the fine particles that can cause respiratory irritation.
However, for gaseous smoke components and odors, the standard configuration has limitations. Kitchen fires produce various volatile organic compounds (VOCs) and other gaseous contaminants that HEPA filtration alone cannot address. These components require activated carbon or other adsorbent media for effective removal.
For optimal smoke remediation performance, the Guardian R Pro should be equipped with the optional activated carbon pre-filter or supplemental carbon filtration. With this addition, the unit becomes substantially more effective at addressing both the particulate and gaseous components of fire-related contamination.
In a practical application following a small kitchen fire:
- The unit can clear visible smoke from a typical living space within 1-3 hours
- Significant reduction of smoke odors (with carbon filtration) might take 24-48 hours of continuous operation
- Placement matters significantly – positioning the unit to create circular airflow patterns improves efficiency
- Multiple units may be necessary for larger homes or more serious fire events
For professional fire restoration, the Guardian R Pro is often used as part of a comprehensive approach that also includes surface cleaning, HVAC cleaning, and possibly thermal fogging or ozone treatment (performed by professionals when the space is unoccupied).
What clearances are needed around the Phoenix Guardian R Pro for proper airflow and safe operation?
The Phoenix Guardian R Pro requires specific clearances around the unit to ensure optimal airflow, effective operation, and safety. Following these clearance guidelines maximizes performance while preventing potential issues:
For the air intake side (where air enters the unit), maintain a minimum of 12 inches of unobstructed space. This prevents restriction of airflow that could reduce cleaning capacity and potentially strain the motor. In high-dust environments, consider increasing this clearance to 18-24 inches.
For the exhaust side (where filtered air exits), maintain a minimum of 24 inches of clear space. This allows proper air discharge without creating back pressure. If using ducting for negative air applications, ensure the ducting follows manufacturer specifications for maximum length and minimum bends.
For the sides of the unit not containing intake or exhaust ports, maintain at least 6 inches of clearance from walls and other objects. This facilitates proper air circulation around the unit and prevents overheating.
From the top of the unit, maintain at least 12 inches of clearance. Never stack items on top of the air scrubber as this can restrict airflow and create potential safety hazards.
Additional placement considerations include:
- Position on a level, stable surface to prevent tipping
- Keep away from water sources or areas where liquid spills are likely
- Ensure the power cord path doesn’t create tripping hazards
- For maximum effectiveness, place the unit in a central location within the space being treated
- In multi-room scenarios, position in hallways or central areas to maximize air exchange between spaces
These clearance requirements reflect the industrial design of the unit, which prioritizes performance over compact footprint. Proper placement according to these guidelines ensures safe operation while maximizing the air cleaning capacity of the system.
