The PURISYSTEMS Air Scrubber is a high-capacity portable air purifier designed for homeowners dealing with mold, smoke, construction dust, or persistent odors. It moves 900 cubic feet per minute through a multi-stage filtration system that includes HEPA filters and UV-C light technology.
This unit covers up to 1100 square feet, making it suitable for basements, garages, workshops, or large living areas. Unlike whole-home HVAC systems, this is a standalone unit you can move from room to room.
It features a metal housing, adjustable fan speeds, and a timer function. The combination of mechanical filtration and UV-C light targets airborne particles, volatile organic compounds, and biological contaminants.
But does it really work for serious air quality problems? Let’s find out.
Is the PURISYSTEMS Air Scrubber Worth It?
Product Overview
The PURISYSTEMS Air Scrubber 900 CFM is a commercial-grade portable air purifier built for heavy-duty applications. It uses a three-stage filtration system with a pre-filter, HEPA filter, and activated carbon layer, plus an optional UV-C light for additional disinfection.
This unit is designed for contractors, restoration professionals, and homeowners dealing with serious air quality issues. It handles post-construction cleanup, flood restoration, wildfire smoke, mold remediation, and persistent pet odors.
The metal construction feels solid and durable. The controls are simple with a dial for fan speed and a timer that goes up to 12 hours. Setup takes less than five minutes.
How It Works
Air enters through the intake vents where a washable pre-filter catches large particles like dust, hair, and debris. This extends the life of the more expensive HEPA filter.
Next, the air passes through a true HEPA filter that captures 99.97% of particles as small as 0.3 microns. This includes pollen, mold spores, fine dust, and most bacteria.
The activated carbon layer absorbs volatile organic compounds, chemical fumes, and odor molecules. Finally, the optional UV-C light exposes passing air to ultraviolet radiation that can damage the DNA of microorganisms.
Unlike ionizers that release charged particles into your room, this unit contains all filtration inside the housing. Unlike whole-home HVAC air purifiers, you can move it wherever you need it most.
Safety & Certifications
The PURISYSTEMS Air Scrubber does not produce ozone as part of its normal operation. The UV-C light is contained inside the unit and does not create ozone at measurable levels when used as directed.
The unit does not appear to carry CARB certification, which is required for air cleaners sold in California. This may limit availability in that state.
There is no EPA registration number listed, which is typical for mechanical air purifiers that do not make pesticide claims. The HEPA filter meets standard filtration specifications used across the industry.
| Safety Factor | PURISYSTEMS Air Scrubber | EPA Guideline |
|---|---|---|
| Ozone Production | None (mechanical filtration) | <0.05 ppm safe limit |
| CARB Certification | Not listed | Required for CA sales |
| Filter Type | True HEPA (99.97% at 0.3 microns) | Industry standard |
Real-World Performance
The 900 CFM airflow rate means this unit can process the air in an 1100 square foot room roughly 4-5 times per hour. This meets the recommended air exchange rate for effective purification.
HEPA filtration is highly effective against mold spores, pollen, pet dander, and dust mites. Activated carbon handles VOCs from paint, cleaning products, and building materials reasonably well, though heavy chemical exposure may require more frequent filter changes.
Smoke removal works best when the unit runs during and immediately after the smoke event. Wildfire smoke particles are within the HEPA filter’s capture range. The carbon layer helps with smoke odor but may saturate quickly with heavy exposure.
The UV-C light provides supplemental disinfection but should not be considered the primary defense against viruses or bacteria. The HEPA filter does most of the work capturing airborne pathogens.
Installation & Maintenance
This is a portable unit that requires no installation. Place it on the floor, plug it into a standard 120V outlet, and turn it on. The unit weighs about 35 pounds, so moving it between rooms is manageable for most adults.
For best results, position the unit away from walls with at least 12 inches of clearance on all sides. This allows proper airflow and prevents recirculation of unfiltered air.
The pre-filter should be cleaned every two weeks during heavy use. Remove it, rinse with water, let it dry completely, and reinstall. The HEPA filter needs replacement every 6-12 months depending on usage and air quality conditions.
The activated carbon layer typically lasts 3-6 months before odor absorption declines. Replace it sooner if you notice smells returning. The UV-C bulb lasts approximately 10,000 hours of operation.
Cost & Value
The PURISYSTEMS Air Scrubber typically retails between $250 and $350. This positions it as a mid-range option for high-capacity portable air purifiers.
Annual operating costs include filter replacements and electricity. A replacement HEPA filter costs approximately $40-60. Activated carbon filters run $20-30. Budget about $100-120 per year for consumables with moderate use.
Electricity consumption at high speed is roughly 200-250 watts. Running 8 hours per day costs about $7-10 per month at average US electricity rates.
Total first-year cost is approximately $500-600 including the unit and consumables. This compares favorably to professional air purifier rentals which can cost $100-200 per week.

How effective is the PURISYSTEMS Air Scrubber at removing VOCs in a room up to 1100 sq. ft.?
The PURISYSTEMS Air Scrubber uses activated carbon filtration to remove volatile organic compounds from indoor air. Carbon works by adsorption, trapping gas molecules in microscopic pores throughout the filter material.
In a 1100 square foot room, the 900 CFM airflow rate processes the entire air volume approximately 4-5 times per hour. This turnover rate allows the carbon filter multiple opportunities to capture VOC molecules as they circulate through the unit.
Effectiveness depends heavily on the type and concentration of VOCs present. The carbon layer handles common household VOCs like formaldehyde from furniture, benzene from cleaning products, and terpenes from air fresheners reasonably well.
Heavy chemical exposure from fresh paint, new carpeting, or construction materials may saturate the carbon filter more quickly. You may need to replace the carbon layer every 3-4 months instead of the standard 6-month interval.
The unit does not remove all VOCs instantly. Expect noticeable improvement within 2-4 hours of continuous operation in a moderately affected room. Severe chemical odors may require 24-48 hours of runtime plus source removal.
What is the noise level of the PURISYSTEMS Air Scrubber during operation at high speed?
The PURISYSTEMS Air Scrubber produces approximately 65-70 decibels at maximum speed. This is comparable to a vacuum cleaner or busy restaurant conversation.
At low speed, the noise level drops to around 50-55 decibels. This is similar to moderate rainfall or a quiet office environment. Medium speed runs at approximately 58-62 decibels.
The noise comes primarily from the high-velocity fan moving 900 cubic feet of air per minute. The metal housing may amplify some vibration noise if the unit sits on a hard floor without rubber feet or a mat underneath.
For daytime use in workshops, garages, or unoccupied spaces, the noise level is not usually a concern. For bedroom use during sleep, you will likely want to run the unit on low speed or use it intermittently.
Some users report a slight humming from the UV-C ballast, though this is generally much quieter than the fan noise. The sound is consistent rather than variable, which some people find easier to adapt to.
How often do I need to replace the filters in the PURISYSTEMS Air Scrubber?
Filter replacement frequency depends on your usage pattern and air quality conditions. The pre-filter requires cleaning rather than replacement and should be washed every two weeks during active use.
The HEPA filter typically lasts 6-12 months with normal residential use. Replace it sooner if you notice reduced airflow, increased noise, or if the unit struggles to clear the air as effectively as when new.
The activated carbon layer needs replacement every 3-6 months. Heavy odor exposure from pets, smoking, or chemical work shortens this timeline. Replace the carbon filter when you notice odors taking longer to clear.
The UV-C bulb lasts approximately 10,000 hours. At 8 hours per day of use, this equals about 3-4 years. The bulb will still produce light when it needs replacement, but the UV-C intensity diminishes over time.
| Filter Component | Replacement Interval | Approximate Cost |
|---|---|---|
| Pre-Filter | Clean every 2 weeks | $0 (washable) |
| HEPA Filter | 6-12 months | $40-$60 |
| Carbon Filter | 3-6 months | $20-$30 |
| UV-C Bulb | 10,000 hours (3-4 years) | $25-$40 |
Can the PURISYSTEMS Air Scrubber handle smoke removal effectively in a kitchen environment?
The PURISYSTEMS Air Scrubber can handle smoke particles effectively but is not designed to replace a kitchen exhaust hood. Cooking smoke contains both particles and grease-laden vapor that behave differently in air purification systems.
The HEPA filter captures smoke particles very effectively. These particles fall within the 0.3 to 1.0 micron range where HEPA filters perform best. The activated carbon layer absorbs smoke odor molecules.
Grease vapor from frying or searing can coat the pre-filter and HEPA filter, reducing their effectiveness over time. This is why kitchen exhaust systems vent to the outside rather than filtering and recirculating air.
For occasional smoke from burned food or small cooking mishaps, the unit works well. Position it away from the stove to avoid direct grease exposure. Run it on high speed during and after cooking.
For heavy daily cooking with high-heat methods, install a proper range hood that vents outside. Use the air scrubber as supplemental filtration for the dining area rather than primary kitchen ventilation.
What type of filter does the PURISYSTEMS Air Scrubber use, and how does it affect performance against allergens?
The PURISYSTEMS Air Scrubber uses a true HEPA filter rated to capture 99.97% of particles at 0.3 microns. This specification is the industry standard for high-efficiency particulate air filtration.
Common allergens fall well within the HEPA filter’s capture range. Pollen particles measure 10-100 microns, mold spores range from 3-40 microns, dust mite debris is 5-20 microns, and pet dander measures 2-10 microns.
The 0.3 micron specification represents the most penetrating particle size, where filters are least efficient. Particles both larger and smaller than 0.3 microns are actually captured at higher rates due to different physical mechanisms.
For allergy sufferers, HEPA filtration is considered the gold standard. The filter physically traps allergen particles, preventing them from recirculating into your breathing space. This is more reliable than ionizers or electrostatic systems that may allow some particles to settle on surfaces.
The 900 CFM airflow ensures allergen-laden air passes through the HEPA filter multiple times per hour. This repeated filtration progressively reduces allergen concentrations in the room.
Is the PURISYSTEMS Air Scrubber suitable for large basements or just smaller rooms?
The PURISYSTEMS Air Scrubber handles basements up to 1100 square feet effectively when the space is relatively open. The 900 CFM airflow provides adequate air exchange for this coverage area.
Basement layout significantly affects performance. Open basements with minimal walls or partitions allow better air circulation. Finished basements with multiple closed rooms may require repositioning the unit or using multiple units.
Basement ceiling height also matters. The 1100 square foot coverage assumes standard 8-foot ceilings. If your basement has 10-foot ceilings, the actual air volume increases by 25%, which may extend purification time.
Basements often have unique air quality challenges including musty odors, higher humidity, and potential mold growth. The HEPA filter captures mold spores effectively. The carbon layer helps with musty smells. The UV-C light provides additional antimicrobial action.
For large basements over 1100 square feet, you might consider a smaller unit like the PURISYSTEMS 600 CFM model for supplemental coverage in separate rooms or zones.
How does the CADR rating for the PURISYSTEMS Air Scrubber compare to similar air scrubbers?
The PURISYSTEMS Air Scrubber does not list a CADR (Clean Air Delivery Rate) rating in its specifications. CADR testing is typically performed on residential air purifiers rather than commercial air scrubbers.
CADR measures how quickly a purifier removes smoke, dust, and pollen from a test chamber. It is expressed in cubic feet per minute for each contaminant type. Higher numbers indicate faster cleaning.
The 900 CFM airflow specification tells you how much air moves through the unit but not how much of that air is effectively cleaned. A rough estimate suggests the effective CADR might be 70-80% of the airflow rate, or 630-720 CFM.
Commercial air scrubbers focus on different metrics than residential purifiers. They prioritize high airflow for rapid air exchanges in large spaces rather than optimizing for CADR test protocols.
For comparison purposes, high-end residential air purifiers typically achieve CADR ratings of 300-450 CFM. The PURISYSTEMS unit likely exceeds this due to its much higher airflow capacity, though without official testing we cannot state exact figures.
Does the PURISYSTEMS Air Scrubber require professional installation, or can I set it up myself?
The PURISYSTEMS Air Scrubber requires no professional installation. Setup takes less than five minutes and requires no tools or special knowledge.
Remove the unit from the box and place it on a flat, stable surface. Remove any protective packaging from the filters inside the unit. Plug the power cord into a standard 120V household outlet.
Select your desired fan speed and set the timer if you want automatic shutoff. The unit begins operating immediately. There are no apps to download, WiFi to configure, or settings to program.
The only consideration is electrical capacity. At maximum speed, the unit draws approximately 2-2.5 amps. This is well within the capacity of any standard household circuit. Avoid using extension cords longer than 25 feet, which can cause voltage drop.
Unlike HVAC-integrated systems that require ductwork modification and professional installation, this portable unit offers true plug-and-play convenience. Move it from room to room as needed without any reconfiguration.
How does the PURISYSTEMS Air Scrubber perform in terms of odor elimination in a pet-friendly home?
The PURISYSTEMS Air Scrubber handles pet odors through two mechanisms: the HEPA filter captures dander and hair particles, while the activated carbon layer absorbs odor molecules.
Pet dander is one of the easier contaminants for HEPA filters to capture. Particles measure 2-10 microns, well above the 0.3 micron rating. Reduced dander levels often lead to noticeable odor improvement since dander carries much of the pet smell.
The activated carbon filter absorbs ammonia from urine, organic compounds from pet bedding, and general animal odors. The 900 CFM airflow ensures odor-laden air cycles through the carbon filter multiple times per hour.
For best results in pet-friendly homes, run the unit continuously on low or medium speed rather than intermittently on high. This maintains consistently low odor levels rather than allowing buildup between cleaning cycles.
Expect to replace the carbon filter more frequently with multiple pets, typically every 3-4 months instead of 6. Clean the pre-filter weekly to prevent pet hair from restricting airflow. Vacuum around the unit regularly to prevent hair accumulation on the exterior vents.
What cleaning procedures are recommended for maintaining the PURISYSTEMS Air Scrubber?
Regular maintenance keeps the PURISYSTEMS Air Scrubber operating efficiently and extends filter life. The pre-filter requires the most frequent attention.
Remove the pre-filter every two weeks during active use. Rinse it thoroughly under running water until the water runs clear. Let it air dry completely before reinstalling, which typically takes 4-6 hours.
Wipe down the exterior housing monthly with a damp cloth. Avoid harsh chemicals or abrasive cleaners that might damage the finish. Check the air intake and outlet vents for dust accumulation and vacuum if needed.
Inspect the HEPA filter monthly through the access panel if your model allows visual inspection. Replace it when it appears dark gray or black throughout, or when airflow noticeably decreases.
Clean the UV-C bulb every 3-4 months by gently wiping it with a soft, dry cloth while the unit is unplugged. Skin oils and dust on the bulb surface reduce UV-C output.
Keep the area around the unit clear of debris and dust. Vacuum the floor beneath and around the unit weekly to prevent recirculation of settled contaminants.
Is the PURISYSTEMS Air Scrubber ENERGY STAR certified, and what does that mean for energy consumption?
The PURISYSTEMS Air Scrubber does not carry ENERGY STAR certification. This program typically applies to residential air purifiers rather than commercial-grade air scrubbers.
ENERGY STAR certified air purifiers must meet specific energy efficiency criteria while maintaining minimum performance standards. The certification helps consumers identify products that use less electricity for a given level of air cleaning.
Without ENERGY STAR certification, you can still estimate operating costs based on power consumption. At maximum speed, the unit draws approximately 200-250 watts. At low speed, consumption drops to roughly 80-120 watts.
Running 8 hours per day at high speed consumes about 60 kilowatt-hours per month. At the average US electricity rate of $0.13 per kWh, this costs approximately $7-8 per month. Low-speed operation reduces this to about $3-4 monthly.
Commercial air scrubbers prioritize high airflow and rapid air exchange over maximum energy efficiency. The higher power consumption is offset by faster air cleaning and the ability to handle larger spaces with a single unit.
How does the UV-C technology in the PURISYSTEMS Air Scrubber enhance its effectiveness?
The UV-C light in the PURISYSTEMS Air Scrubber provides supplemental disinfection by exposing passing air to ultraviolet radiation at 254 nanometers wavelength. This energy damages the DNA and RNA of microorganisms.
As air passes through the unit, it flows past the UV-C bulb for a brief exposure period. This exposure can inactivate bacteria, viruses, and mold spores that pass close to the bulb.
The effectiveness depends on exposure time and intensity. Air moving at 900 CFM passes the bulb very quickly, limiting exposure time. The UV-C provides an additional layer of protection but should not be considered the primary disinfection method.
The HEPA filter does most of the work removing microorganisms by physically trapping them. The UV-C acts on anything that might pass through the filter or on organisms trapped in the filter itself, helping prevent microbial growth on the filter media.
UV-C is most effective against mold spores and bacteria. Viruses require higher UV-C doses for reliable inactivation. The contained design ensures no UV-C light escapes the housing, eliminating any risk to occupants or pets.
Are there any child or pet safety concerns associated with using the PURISYSTEMS Air Scrubber?
The PURISYSTEMS Air Scrubber is generally safe for homes with children and pets when used as directed. The metal housing can become slightly warm during extended operation but not hot enough to cause burns.
The air intake vents have spacing that prevents small fingers from reaching internal components. However, the unit is not childproof. Children should be supervised around the device to prevent them from changing settings or attempting to insert objects into vents.
The UV-C bulb is completely contained inside the housing. No UV-C light escapes during normal operation. This eliminates concerns about eye or skin exposure that would exist with open UV-C systems.
The unit produces no ozone or other harmful emissions. The HEPA filtration is entirely mechanical and safe for individuals with asthma or respiratory sensitivities. The activated carbon does not release absorbed chemicals back into the air.
Position the unit where it cannot be easily tipped over. At 35 pounds, it is heavy enough to cause injury if it fell on a child or pet. Secure the power cord to prevent tripping hazards.
Can I place the PURISYSTEMS Air Scrubber in a corner, or does it need a certain clearance from walls?
The PURISYSTEMS Air Scrubber needs adequate clearance from walls and furniture for optimal airflow. Place the unit with at least 12 inches of clearance on all sides where vents are located.
Corner placement restricts airflow and reduces effectiveness. The unit pulls air from intake vents and expels it from outlet vents. Blocking either side creates back pressure that reduces airflow and can strain the motor.
Check your specific model to identify vent locations. Most air scrubbers have intake vents on the sides or front and outlet vents on the top or back. Position the unit so all vents have unobstructed access to room air.
Placing the unit in the center of the room provides the best air circulation but is often impractical. A location along a wall with proper clearance works well for most applications.
Avoid placing the unit under tables, desks, or shelves that might restrict upward airflow. Keep curtains, papers, and other materials away from vents. Check monthly that clearances remain adequate as furniture arrangements change.
What are the specific smart features of the PURISYSTEMS Air Scrubber, and how do they improve usability?
The PURISYSTEMS Air Scrubber does not include smart features like WiFi connectivity, app control, or air quality sensors. This is a manually controlled unit designed for simplicity and durability.
The controls consist of a fan speed dial with three settings (low, medium, high) and a mechanical timer that allows automatic shutoff up to 12 hours. These analog controls are reliable and require no technical knowledge.
The lack of smart features is intentional for commercial-grade equipment. Contractors and restoration professionals need equipment that works reliably in harsh environments without depending on phone apps or internet connections.
The timer function is the main convenience feature. Set it when you leave a space and the unit automatically shuts off after the specified period. This prevents energy waste and extends filter life.
If you need air quality monitoring, smart controls, or remote operation, you would need to consider residential air purifiers with these features. Those units typically sacrifice airflow capacity and durability for smart functionality.
What kind of warranty coverage does the PURISYSTEMS Air Scrubber come with?
The PURISYSTEMS Air Scrubber typically comes with a one-year limited manufacturer warranty covering defects in materials and workmanship. This is standard for commercial air scrubbers in this price range.
The warranty covers the housing, motor, electrical components, and UV-C ballast. It does not cover consumable items like filters, which are considered normal replacement parts.
Warranty service typically requires you to contact the manufacturer or seller for troubleshooting. They may request photos or videos of the issue. If the problem cannot be resolved remotely, they may issue a return authorization.
Some retailers offer extended warranty options for purchase at the time of sale. These typically extend coverage to 2-3 years and may include additional protections.
Keep your purchase receipt and product documentation. Note the date of purchase and serial number. Register the product with the manufacturer if registration is available, though this is not always required for warranty claims.
How do customers rate the performance of the PURISYSTEMS Air Scrubber for allergy reduction in bedrooms?
Customer feedback indicates the PURISYSTEMS Air Scrubber reduces allergy symptoms effectively but with some tradeoffs for bedroom use. The HEPA filtration successfully removes pollen, dust mites, and pet dander that trigger allergies.
Users report noticeable improvement in morning congestion and nighttime breathing within 3-5 days of continuous use. Bedrooms require several days of operation to reduce accumulated allergen loads in carpets, bedding, and curtains.
The main complaint for bedroom use is noise level. At high speed, the 65-70 decibel output is too loud for most people to sleep through. Low speed operation at 50-55 decibels is more acceptable but still noticeable.
Some users run the unit on high speed for 2-3 hours before bedtime, then switch to low speed or turn it off during sleep. Others leave it running continuously on low speed and report adapting to the white noise within a week.
For best results, place the unit across the room from the bed rather than on a nightstand. This reduces direct noise exposure while still providing effective air circulation.
What are the best operational settings for the PURISYSTEMS Air Scrubber during night use?
For overnight operation, run the PURISYSTEMS Air Scrubber on low speed to balance air purification with acceptable noise levels. Low speed produces 50-55 decibels, comparable to a quiet office or moderate rainfall.
If noise is still bothersome, run the unit on high speed for 2-3 hours before bedtime. This provides intensive air cleaning while the room is unoccupied. Switch to low speed or turn off the unit when you go to bed.
Close bedroom doors and windows during operation to prevent unfiltered air from entering. This allows the unit to progressively reduce allergen and particle concentrations without constant influx of new contaminants.
Position the unit away from the bed to minimize noise disturbance. Across the room or in a corner with proper clearance works well. Point the outlet vent away from the bed to avoid direct airflow.
Use the timer function if you prefer the unit to shut off automatically. Set it for 4-6 hours if you turn it on at bedtime. This provides air cleaning during the early part of your sleep when you may be more tolerant of noise.
How does the weight of the PURISYSTEMS Air Scrubber affect its portability?
The PURISYSTEMS Air Scrubber weighs approximately 35 pounds with filters installed. This weight makes it portable for most adults but not as convenient to move as smaller residential air purifiers.
The metal housing accounts for much of the weight but provides durability and stability. The unit does not include wheels or handles, so you must lift and carry it when moving between rooms.
One person can move the unit short distances without difficulty. Carrying it up or down stairs requires more effort and may be challenging for individuals with limited strength or mobility issues.
The weight prevents the unit from tipping over easily during operation. High airflow can create vibration, but the substantial weight keeps the unit stable on most surfaces.
For frequent room-to-room movement, consider leaving the unit in the space with the worst air quality. For occasional repositioning, the 35-pound weight is manageable. If you need a more portable solution for smaller spaces, lighter residential units may be more practical.
What are the expected operating costs for the PURISYSTEMS Air Scrubber based on filter replacement and energy consumption?
First-year operating costs include the purchase price plus consumables and electricity. Assuming moderate use of 8 hours per day, expect the following breakdown.
Filter replacements cost approximately $100-120 annually. This includes one HEPA filter ($40-60), two carbon filters ($40-60 total), and periodic pre-filter cleaning at no cost. Add $25-40 every 3-4 years for UV-C bulb replacement.
Electricity consumption at medium speed averages about 150 watts. Running 8 hours daily equals 36 kilowatt-hours per month or 432 kWh annually. At $0.13 per kWh national average, this costs about $56 per year.
Total annual operating costs are approximately $160-180 for moderate use. Heavy use with 16-24 hours daily operation increases filter replacement frequency and electricity costs to roughly $250-300 annually.
| Cost Category | Moderate Use (8 hrs/day) | Heavy Use (16 hrs/day) |
|---|---|---|
| HEPA Filter | $40-$60/year | $60-$90/year |
| Carbon Filter | $40-$60/year | $60-$90/year |
| Electricity | $56/year | $112/year |
| Total Annual | $160-$180 | $250-$300 |
Does the PURISYSTEMS Air Scrubber emit any ozone, and is that a concern for indoor air quality?
The PURISYSTEMS Air Scrubber does not produce ozone as part of its normal operation. It uses mechanical HEPA filtration and activated carbon, neither of which generates ozone.
The UV-C light can theoretically produce trace amounts of ozone when UV-C wavelengths below 240 nanometers interact with oxygen. However, the UV-C bulb in this unit operates at 254 nanometers and is contained inside the housing.
Any ozone production from the UV-C light would be below measurable levels and well within safe exposure limits. The EPA recommends indoor ozone levels remain below 0.05 parts per million. Mechanical filtration systems like this one typically measure at or near zero.
Ozone concerns primarily apply to ionic air purifiers and ozone generators, which intentionally produce ozone as part of their purification mechanism. Those devices can produce 0.05 to 0.25 ppm or higher.
For those considering alternatives, the ALORAIR PureAiro HEPA Max 970 offers similar coverage with comparable filtration technology and verified low ozone output. If you have asthma, COPD, or respiratory sensitivities, mechanical HEPA filtration remains the safest choice.
