Is Dri-Eaz HEPA 700 Air Scrubber Worth It?
Product Overview
The Dri-Eaz HEPA 700 is a commercial-grade air scrubber designed to remove airborne contaminants in challenging environments. It’s built specifically for restoration contractors, construction teams, and industrial applications where air quality is compromised.
First impressions of this unit are positive. The housing is constructed from rotomolded polyethylene that can withstand job site abuse. The control panel is straightforward with an easy-to-read filter indicator light and variable speed control.
Performance-wise, the 700 CFM capacity puts it in the upper tier of portable air scrubbers, making it suitable for medium to large spaces with significant contamination issues.
How It Works
The Dri-Eaz HEPA 700 works through a multi-stage filtration process. First, air is drawn into the unit through a pre-filter that captures larger particles like dust and debris. This pre-filter extends the life of the more expensive HEPA filter.
Next, the air passes through the true HEPA filter, which removes 99.97% of particles as small as 0.3 microns, including fine dust, mold spores, allergens, and most bacteria.
Finally, the clean air is discharged through the outlet, creating a continuous circulation pattern that gradually reduces airborne contaminants throughout the space.
Unlike some competitors that rely solely on carbon filtration or ionization, the Dri-Eaz uses proven HEPA technology that physically captures particles rather than just charging them. This approach is more effective for restoration scenarios than lower-capacity 500 CFM units that might struggle with heavily contaminated air.

Its commercial-grade construction and powerful performance justify the investment for those who need reliable, heavy-duty air cleaning.
Homeowners with average air quality concerns might find it overkill for everyday use. Those with smaller spaces or less severe contamination issues might be better served by a less powerful unit at a lower price point.
If you’re dealing with water damage restoration, mold remediation, construction cleanup, or other situations requiring serious air filtration, the Dri-Eaz HEPA 700 delivers the performance and durability professionals demand.
What is the actual square footage the Dri-Eaz HEPA 700 can effectively clean in a room with high dust levels?
While the Dri-Eaz HEPA 700 Air Scrubber has a 700 CFM rating, its effective coverage area varies significantly based on contamination levels. In rooms with high dust levels, the practical coverage is approximately 350-450 square feet for optimal performance.
This reduction from the maximum theoretical coverage occurs because heavy particulate contamination requires more air changes per hour (ACH) to maintain good air quality. Industry standards recommend 6-10 ACH for environments with high dust levels.
The formula for determining effective coverage is:
Effective Square Footage = (CFM × 60) ÷ (Ceiling Height × Desired ACH)
For a standard room with 8-foot ceilings and 8 ACH for high dust levels:
Coverage = (700 × 60) ÷ (8 × 8) = 42,000 ÷ 64 = 656 square feet
However, this theoretical calculation doesn’t account for real-world factors like furniture obstruction, room layout, and air circulation patterns. In practice, restoration professionals typically reduce this number by 30-40% for heavily contaminated environments.
For maximum effectiveness in high dust environments, using the unit in a slightly smaller area than its maximum rating ensures more thorough air cleaning. Multiple units may be necessary for larger spaces with significant contamination.
How often does the HEPA filter need to be replaced under normal residential use, and what is the cost?
Under normal residential use, the HEPA filter in the Dri-Eaz HEPA 700 Air Scrubber typically needs replacement every 9-12 months. However, this timeframe can vary based on air quality conditions and usage patterns.
The main HEPA filter costs approximately $100-150 per replacement. This is the most significant maintenance expense associated with the unit. The pre-filter, which protects the HEPA filter from larger particles, should be replaced more frequently—every 30-60 days for residential use—at a cost of $15-25 each.
For a typical residential setting with moderate air quality issues, annual filter costs break down as follows:
| Filter Type | Replacement Frequency | Unit Cost | Annual Cost |
|---|---|---|---|
| HEPA Filter | Every 9-12 months | $100-150 | $100-150 |
| Pre-Filter | Every 30-60 days | $15-25 | $90-300 |
| Total Annual Cost | $190-450 |
It’s important to note that the filter indicator light on the unit will signal when replacement is needed based on actual airflow resistance rather than just time. Following this indicator is more accurate than a strict time-based replacement schedule.
For homes with pets, smokers, or construction activities, filter replacement might be needed more frequently. Conversely, in very clean environments, filters may last longer than the standard recommendation.
Is the Dri-Eaz HEPA 700 suitable for removing smoke odor after a fire, and how long does it typically take?
The Dri-Eaz HEPA 700 Air Scrubber is partially effective for removing smoke odor after a fire, but with important limitations. The standard configuration with HEPA filtration excels at removing smoke particles but has limited capability for removing the gaseous compounds that cause lingering smoke odors.
For complete smoke odor remediation, the unit should be used with optional activated carbon filters. These additional filters can be placed after the HEPA filter to adsorb volatile organic compounds (VOCs) and other gaseous pollutants that create smoke smell.
Timeframe for smoke odor removal varies significantly based on:
1. Severity of the fire damage
2. Types of materials burned
3. Size of the affected space
4. Whether structural elements were affected
For light smoke damage in a standard room (around 300 sq ft), running the Dri-Eaz with carbon filtration might show noticeable improvement within 24-48 hours. Complete odor removal typically requires:
| Smoke Damage Level | Time with Air Scrubber Only | Time with Comprehensive Approach* |
|---|---|---|
| Light (small cooking fire) | 2-3 days | 1-2 days |
| Moderate (contained room fire) | 5-10 days | 3-5 days |
| Severe (major structural fire) | Insufficient alone | 7-14+ days |
*Comprehensive approach includes cleaning surfaces, treating fabrics, and possibly using ozone generators or hydroxyl machines in addition to air scrubbers.
For effective smoke remediation, restoration professionals typically use the Dri-Eaz HEPA 700 as part of a multi-faceted approach that includes cleaning all surfaces, treating fabrics, and addressing structural materials that may have absorbed odors.
Can this air scrubber be used in a basement to reduce musty smells and control humidity-related odors?
Yes, the Dri-Eaz HEPA 700 Air Scrubber can help reduce musty smells and humidity-related odors in basements, though with certain considerations. The unit primarily addresses odors by removing the airborne particles and some of the microorganisms that contribute to musty smells.
For basement applications, the HEPA filter will effectively capture mold spores, dust mites, and other particulate matter that often contribute to basement odors. However, the standard configuration doesn’t directly address humidity or remove all gaseous odor compounds.
For maximum effectiveness in basements, consider these important points:
1. The air scrubber works best when paired with a dehumidifier to address the root cause of many basement odors—excess moisture.
2. For enhanced odor removal, optional activated carbon filters can be added to the unit. These specifically target VOCs and gaseous compounds causing musty smells.
3. The air scrubber should be positioned to maximize air circulation throughout the basement, ideally in a central location with doors to storage areas left open.
Results will vary depending on the basement conditions. In moderately musty basements with humidity properly controlled, users typically report noticeable odor improvement within 24-72 hours of continuous operation. However, the unit won’t resolve structural moisture issues like water intrusion or condensation problems.
For persistent basement odor issues, the most effective approach combines the air scrubber with:
– Dehumidification (maintaining 40-50% relative humidity)
– Proper ventilation
– Addressing any water intrusion points
– Cleaning and removing any visible mold
What are the noise levels in decibels for the Dri-Eaz HEPA 700 on its highest and lowest settings?
The Dri-Eaz HEPA 700 Air Scrubber operates at different noise levels depending on the selected speed setting. On its lowest setting, the unit produces approximately 62 decibels (dB), while on its highest setting, it generates around 74 decibels.
To put these noise levels in context:
| Noise Source | Decibel Level (dB) | Comparison |
|---|---|---|
| Normal conversation | 60 dB | Slightly quieter than Dri-Eaz on low |
| Dri-Eaz HEPA 700 (Low) | 62 dB | Similar to background conversation |
| Vacuum cleaner | 70 dB | Between Dri-Eaz low and high settings |
| Dri-Eaz HEPA 700 (High) | 74 dB | Noticeable but not uncomfortable |
| City traffic | 80 dB | Louder than Dri-Eaz on high |
The variable speed control allows users to balance air cleaning performance with noise considerations. At its lowest setting, the unit is quiet enough for most occupied spaces, though still noticeable. The medium setting (around 68 dB) offers a good compromise between performance and noise for many applications.
For overnight use in occupied areas like bedrooms, the low setting is generally preferred. For unoccupied spaces or during active remediation work, the higher settings can be used without concern for noise disruption.
The sound character is primarily a consistent fan noise without significant tonal qualities or vibration, which many users find less intrusive than other types of mechanical noise at similar decibel levels.
Does the unit produce any ozone, and is it certified to be safe for use around people with asthma?
The Dri-Eaz HEPA 700 Air Scrubber does not intentionally produce ozone as part of its air cleaning process. Unlike some air purifiers that use ozone generation or ionization technologies, this unit relies solely on mechanical filtration through its pre-filter and HEPA filter system.
The absence of ozone production makes the Dri-Eaz HEPA 700 generally suitable for use around people with asthma and other respiratory sensitivities. Ozone, even at low levels, can irritate the respiratory system and potentially trigger asthma attacks in sensitive individuals.
While the unit doesn’t carry a specific asthma certification from organizations like the Asthma and Allergy Foundation of America (AAFA), its HEPA filtration technology is widely recognized as beneficial for asthma sufferers. HEPA filters remove the common asthma triggers like:
– Dust mites and their waste products
– Pet dander
– Mold spores
– Pollen
– Fine particulate matter
For asthma sufferers, the benefits of the Dri-Eaz HEPA 700 include:
1. Removal of 99.97% of airborne particles as small as 0.3 microns, including many asthma triggers
2. No ozone production that could irritate airways
3. No ionization process that might create charged particles
The unit can be safely operated continuously in occupied spaces, including bedrooms and living areas where people with asthma spend significant time. For maximum benefit, regular filter maintenance is essential to ensure optimal performance and prevent accumulated contaminants from becoming a source of irritation.
How does the 700 CFM rating translate to air changes per hour in a standard-sized bedroom?
The 700 CFM (cubic feet per minute) rating of the Dri-Eaz HEPA 700 Air Scrubber translates to different air changes per hour (ACH) depending on the room size. For a standard-sized bedroom, this unit provides remarkably high air exchange rates.
To calculate air changes per hour, we use the formula:
ACH = (CFM × 60) ÷ Room Volume in cubic feet
For typical bedroom sizes:
| Room Size | Room Volume (8ft ceiling) | Air Changes Per Hour |
|---|---|---|
| Small Bedroom (10′ × 10′) | 800 cubic feet | 52.5 ACH |
| Medium Bedroom (12′ × 12′) | 1,152 cubic feet | 36.5 ACH |
| Large Bedroom (14′ × 16′) | 1,792 cubic feet | 23.4 ACH |
| Master Suite (16′ × 20′) | 2,560 cubic feet | 16.4 ACH |
For context, most residential air purifiers aim for 4-6 air changes per hour, while hospital isolation rooms typically require 12 ACH. The Dri-Eaz HEPA 700 significantly exceeds these benchmarks in typical bedroom settings.
This high ACH rate explains why the unit can rapidly improve air quality in residential settings. In a medium bedroom, the air scrubber filters the entire room’s air approximately once every 1.6 minutes at full capacity.
Such high air exchange rates are particularly valuable for:
– Rapid cleanup after contamination events
– Mold remediation projects
– Helping people with severe allergies
– Creating clean room conditions for sensitive activities
The variable speed control allows users to reduce the airflow (and noise) once the initial air cleaning is complete, maintaining good air quality with fewer air changes per hour during ongoing operation.
What is the power consumption in watts for the Dri-Eaz HEPA 700 Air Scrubber?
The Dri-Eaz HEPA 700 Air Scrubber consumes approximately 3.0 amps at 115V, which translates to around 345 watts at maximum airflow. Power consumption varies based on the selected speed setting, with lower settings drawing significantly less power.
Here’s a breakdown of the approximate power consumption at different speed settings:
| Speed Setting | Approximate Power Consumption | Hourly Cost (at $0.15/kWh) |
|---|---|---|
| Low | 150-200 watts | $0.023-0.030 |
| Medium | 250-300 watts | $0.038-0.045 |
| High | 325-345 watts | $0.049-0.052 |
For continuous operation, the energy costs add up as follows:
– Daily operation (24 hours) at high speed: $1.18-1.25
– Monthly operation at high speed: $35.40-37.50
– Annual operation at high speed: $424.80-450.00
Most users don’t run the unit at maximum speed continuously. A typical usage pattern might involve:
1. High speed for initial cleanup (2-4 hours)
2. Medium speed for maintenance during daytime (8-12 hours)
3. Low speed during nighttime or when sensitivity to noise is higher (8-12 hours)
This variable usage pattern would result in significantly lower operating costs than continuous high-speed operation.
The power consumption is relatively efficient considering the 700 CFM airflow rate. Many competing commercial air scrubbers with similar performance specifications consume more power, making the Dri-Eaz a relatively energy-efficient option in its class.

3. Pay for shipping to the service center (if required)
4. Describe the issue in detail
Some distributors or rental companies may offer extended warranty options or service plans beyond the standard manufacturer’s warranty. These extended plans may provide additional coverage periods or include services like regular maintenance and filter replacements.
For commercial users who depend on the equipment for business operations, verifying the warranty terms before purchase and considering extended protection options may be worthwhile, especially given the unit’s role in critical restoration or remediation projects.
Does the Dri-Eaz HEPA 700 have a pre-filter, and if so, is it washable or disposable?
Yes, the Dri-Eaz HEPA 700 Air Scrubber does include a pre-filter, which is disposable rather than washable. This pre-filter (part number F271) is designed to capture larger particles before they reach the main HEPA filter, extending the life of the more expensive HEPA component.
The pre-filter is made of a non-woven polyester material optimized for capturing:
– Dust
– Lint
– Hair
– Large allergens
– Visible particulates
Key characteristics of the pre-filter include:
– Material: Non-woven polyester
– Efficiency rating: Approximately 35-40% efficiency at 2 microns
– Replacement interval: Every 1-2 weeks during heavy use; 4-8 weeks in lighter conditions
– Cost: Approximately $15-25 per filter
– Availability: Often sold in multi-packs for convenience
While the manufacturer does not recommend washing and reusing the pre-filter, some users report carefully vacuuming the surface of the pre-filter to extend its life in less-critical applications. However, this practice:
1. Is not officially endorsed by Dri-Eaz
2. May reduce filtration efficiency
3. Should never be done in mold remediation or hazardous material scenarios
4. Could potentially void warranty if damage results
The pre-filter is essential to the proper operation of the air scrubber and should not be bypassed. Using the unit without a pre-filter will quickly clog the HEPA filter, reducing performance and potentially causing premature failure of the more expensive component.
The pre-filter is easily accessible and designed for simple replacement without tools. It’s located at the air intake side of the unit and can be changed in under a minute by opening the access panel, removing the old filter, and installing a new one.
How do you know when the HEPA filter is saturated and needs to be changed? Is there an indicator?
The Dri-Eaz HEPA 700 Air Scrubber does include a filter monitoring system with an indicator light that alerts users when the HEPA filter requires changing. This feature eliminates guesswork and helps ensure optimal performance.
The filter indicator system works by monitoring airflow restriction through the filters. As filters become loaded with particulates, they restrict airflow, which increases pressure differential across the filter media. The unit’s pressure sensor detects this change and triggers the indicator light when the restriction reaches a predetermined threshold.
The control panel features:
1. A “Filter” indicator light that illuminates when filter replacement is needed
2. Different colored indicators for normal operation vs. maintenance required
Beyond the electronic indicator, users can look for these additional signs that the HEPA filter needs replacement:
| Warning Sign | What It Indicates | Action Required |
|---|---|---|
| Reduced airflow from outlet | Filter restriction limiting performance | Check and replace filters |
| Increased motor noise | Motor working harder against resistance | Check filter condition immediately |
| Visible discoloration on HEPA filter | Heavy particulate loading | Replace filter |
| Odors coming from unit | Captured contaminants potentially releasing VOCs | Replace filter, consider adding carbon filtration |
The filter monitoring system is reasonably accurate for most applications, but certain conditions can affect its reliability:
1. Extremely fine dust that creates high restriction while filters appear visually clean
2. Uneven loading that affects airflow patterns through the filter
3. Very oily contaminants that may affect pressure sensor readings
For critical applications, some professionals implement a time-based replacement schedule in addition to monitoring the indicator. This provides redundancy in environments where filter performance is particularly important.
When replacing filters, it’s advisable to check both the pre-filter and HEPA filter, even if only one appears to need replacement. Often, a severely loaded pre-filter will trigger the indicator before the HEPA filter requires changing.
Is the Dri-Eaz HEPA 700 CARB certified for use in California?
Yes, the Dri-Eaz HEPA 700 Air Scrubber is compliant with California Air Resources Board (CARB) regulations and can be legally used in California. The unit’s compliance stems from its mechanical filtration design that doesn’t produce ozone or other regulated emissions.
CARB certification is particularly relevant for air cleaning devices because California has strict regulations regarding ozone emissions from air purifiers. The regulation (AB 2276) limits ozone emissions to no more than 0.050 parts per million (ppm).
The Dri-Eaz HEPA 700 meets these requirements because:
1. It uses only mechanical filtration through HEPA technology
2. It doesn’t incorporate ozone generators, ionizers, or electrostatic precipitators that might produce ozone
3. It doesn’t rely on photocatalytic oxidation or similar technologies that could potentially generate regulated byproducts
For California users, this compliance means:
– The unit can be legally purchased, sold, and used throughout California
– It’s suitable for commercial restoration businesses operating in California
– It meets the requirements for use in public buildings and regulated workspaces
– No special permits or exemptions are required for its operation
While specific CARB certification documentation may not be prominently featured in marketing materials (as it’s primarily relevant to electrically-powered air cleaners that use ion generators, electrostatic precipitators, or ozone generators), the unit’s mechanical filtration design inherently complies with the regulations.
For professional restoration contractors in California, the Dri-Eaz HEPA 700 represents a compliant option that avoids potential regulatory issues associated with some alternative air cleaning technologies that might produce ozone or other regulated emissions.
What type of electrical outlet does it require, and what is the length of the power cord?
The Dri-Eaz HEPA 700 Air Scrubber operates on standard household electricity and comes with the following electrical specifications:
Electrical Requirements:
– Voltage: 115V (North American version)
– Frequency: 60 Hz
– Amperage: 3.0 amps
– Plug type: Standard 3-prong grounded plug (NEMA 5-15P)
– Circuit requirement: Standard 15-amp household circuit
Power Cord:
– Length: Approximately 25 feet (7.6 meters)
– Type: 14-gauge, 3-conductor grounded cord
– Color: Yellow (for visibility in work environments)
– Plug: Heavy-duty construction with molded design
The 25-foot cord length offers several advantages:
1. Flexibility in unit placement without requiring extension cords
2. Ability to position the unit optimally for air circulation
3. Reduced tripping hazards from stretched cords
4. Convenience in restoration settings where outlets may be limited
Important electrical considerations when using the unit:
| Consideration | Recommendation |
|---|---|
| Circuit loading | Avoid sharing circuit with high-draw appliances |
| Extension cords | If needed, use minimum 14-gauge rated for 15 amps |
| GFCI protection | Recommended when used in damp locations |
| Cord management | Route cord along walls to prevent tripping hazards |
The unit’s relatively low power draw (345 watts) means it can usually operate on the same circuit as other equipment without tripping breakers, though this depends on what else is connected to the same circuit.
For international users, it’s important to note that the standard North American version requires 115V/60Hz power. Using the unit in countries with different electrical standards (such as 220V/50Hz) would require an appropriate transformer or voltage converter, which is not typically recommended by the manufacturer.
For VOC removal, does the unit require an additional carbon filter, or is the standard configuration sufficient?
The standard configuration of the Dri-Eaz HEPA 700 Air Scrubber with its HEPA filter is not sufficient for significant VOC (Volatile Organic Compound) removal. The HEPA filtration technology is excellent for particulate matter but has limited effectiveness against gaseous pollutants like VOCs.
For effective VOC removal, an additional activated carbon filter (part number F374) is required. This optional filter can be added to the unit’s filtration system and works through adsorption—physically binding gas molecules to the carbon’s surface area.
The carbon filter’s effectiveness varies by VOC type:
| VOC Category | Examples | Standard HEPA Only | With Carbon Filter |
|---|---|---|---|
| Light VOCs | Formaldehyde, Methane | Minimal removal | Moderate removal (30-60%) |
| Medium VOCs | Benzene, Toluene | Very limited removal | Good removal (60-80%) |
| Heavy VOCs | Paint fumes, Solvents | Minimal removal | Very good removal (70-90%) |
| Odors | Smoke, Cooking, Pet odors | Particles only, not odor gases | Good to excellent removal |
When using carbon filters for VOC removal:
1. The carbon filter typically installs after the HEPA filter in the airflow path
2. Carbon filters have a shorter effective lifespan than HEPA filters when exposed to high VOC levels—typically 2-4 months of active use before their adsorption capacity diminishes
3. No indicator light exists specifically for carbon filter saturation; replacement is typically done on a time basis or when odor breakthrough is detected
4. Carbon filters slightly reduce the total airflow of the unit, typically by 5-10%
For applications specifically focused on VOC removal (such as after painting, new construction, or fire restoration), the carbon filter addition is essential. For general particle filtration with minimal VOC concerns, the standard configuration may be sufficient.
It’s worth noting that even with the carbon filter, the Dri-Eaz HEPA 700 is not designed to replace proper ventilation in situations with high VOC levels that might present safety hazards. It’s a complement to, not a replacement for, appropriate ventilation in hazardous environments.
What is the maximum recommended room size for this 700 CFM air scrubber for optimal performance?
The maximum recommended room size for the Dri-Eaz HEPA 700 Air Scrubber depends significantly on the specific application and the desired air changes per hour (ACH). With its 700 CFM (cubic feet per minute) rating, the unit can handle different room sizes based on the level of air quality control needed.
For optimal performance in different scenarios:
| Application Type | Recommended ACH | Maximum Room Size | Calculation |
|---|---|---|---|
| General Air Cleaning (homes, offices) | 4-6 ACH | 875-1,312 sq ft (8′ ceiling) | (700 × 60) ÷ (8 × 4) to (700 × 60) ÷ (8 × 6) |
| Allergen Control | 6-8 ACH | 656-875 sq ft (8′ ceiling) | (700 × 60) ÷ (8 × 6) to (700 × 60) ÷ (8 × 8) |
| Mold Remediation | 8-12 ACH | 437-656 sq ft (8′ ceiling) | (700 × 60) ÷ (8 × 8) to (700 × 60) ÷ (8 × 12) |
| Dust Control (Construction) | 10-15 ACH | 350-525 sq ft (8′ ceiling) | (700 × 60) ÷ (8 × 10) to (700 × 60) ÷ (8 × 15) |
| Containment (Negative Air) | 15-20+ ACH | 262-350 sq ft (8′ ceiling) | (700 × 60) ÷ (8 × 15) to (700 × 60) ÷ (8 × 20) |
For rooms with ceiling heights other than 8 feet, adjustments to these calculations are necessary. Higher ceilings require more air movement for the same air change rate.
Additional factors affecting optimal room size include:
1. Room layout and obstructions that may impede airflow
2. Level of contamination (heavily contaminated spaces require more air changes)
3. Continuous vs. intermittent operation
4. Whether doors and windows are kept closed
For maximum effectiveness, industry professionals often recommend:
– Positioning the unit centrally when possible
– Ensuring doors and windows remain closed during operation
– Using fans to improve air circulation in larger spaces
– Adding additional units for spaces larger than the maximum recommended size
While the unit can technically be used in larger spaces than recommended, the effectiveness and speed of air cleaning will be reduced as room size increases beyond optimal parameters.
