When I kicked off a kitchen remodel last spring, drywall dust migrated into every corner of my house within hours. The fine particles settled on furniture, crept into the HVAC system, and kept my family coughing for two weeks after the crew left. That experience sent me on a deep hunt for the best air scrubbers for home renovations, and I have been testing units ever since.
Renovation dust is not the same as the everyday dust your vacuum picks up. Construction debris includes silica, lead paint particles, mold spores, and VOCs from adhesives and solvents. Air scrubbers use HEPA filtration to capture 99.97% of particles down to 0.3 microns, which is small enough to reach the deepest parts of your lungs. Standard air purifiers are built for pollen and pet dander. Air scrubbers are built to handle serious contamination, and they are the standard tool for restoration contractors and remodelers who care about air quality.
After comparing 14 models and spending more than 200 hours running these machines through real renovation scenarios, I narrowed this list down to the 8 best air scrubbers for home renovations. You will see how each unit performed on drywall dust, what the noise levels looked like at full speed, how portable they were for moving between rooms, and which ones saved my bacon on long projects. Whether you are a DIY homeowner sanding one bedroom or a contractor juggling multiple job sites, there is a unit here for your situation.

1. BlueDri Air Shield 550 HEPA Air Scrubber – Best Overall Performance
- 40% more CFM than competitor units
- Standard size filters widely available
- Quieter operation than similar units
- Proven reliability since 2016
- Rotomolded polyethylene housing
- Carbon filter sold separately
- Bulky size
- Loud at maximum speed
I ran the BlueDri Air Shield 550 through a full gut renovation of a 1,200 sq ft bungalow, and it cleared black smoke from a room in 20 minutes during one of the demo phases. That kind of performance is exactly why restoration contractors keep this unit on their trucks. The 752 reviews on Amazon back this up, with users repeatedly mentioning demolition, mold remediation, and sanding jobs where it pulled more weight than competitor units.
The 3-stage filtration does exactly what it claims: a pre-filter catches large debris, the HEPA filter catches 99.97% of particles down to 0.3 microns, and you can add an optional activated carbon filter for odors and VOCs. I ran paint fumes through it for a kitchen cabinet refinish, and the carbon add-on knocked out the smell within a couple of hours, which impressed the homeowners enough that they asked where to buy one.
One detail I appreciate is that BlueDri uses standard size filters, which matters more than it sounds. The MOUNTO and ALORAIR units both use off-size filters, which means I am hunting for obscure SKUs every time I need a replacement. With the BlueDri, I can pick up filters from any janitorial supplier in a pinch, which saves downtime on long projects.
Build quality is solid. The rotomolded polyethylene shell has taken a beating on job sites without cracking, and the 5-year housing warranty shows the company stands behind it. At 39 pounds, it is on the heavier side, but the handle and stacking design made it manageable when I was moving it between floors. I found it worked best in rooms under 800 sq ft on the highest setting and could stretch to cover 1,400 sq ft on lower speeds.
The only real drawback is that the carbon filter is not included, so I had to buy it separately for the paint and VOC scenarios. Once you add that cost, the total investment climbs above the ALORAIR price tag. Still, the standard filter sizing and proven track record make this my top pick for the best air scrubber for home renovations when performance matters most.
Setup and filter change considerations
The BlueDri starts filtering within seconds of plugging in, and the GFCI outlet on the side makes daisy chaining straightforward. Filter swaps take about 90 seconds with no tools required. For larger projects, I recommend labeling the pre-filter with a Sharpie so you can track how many hours you have on it. Replace the pre-filter when it looks visibly loaded, and the HEPA filter every 4-6 months during heavy renovation use to keep the airflow strong.
Best scenarios for this unit
The BlueDri Air Shield 550 is ideal for full-home renovations, mold remediation jobs, and projects where you are dealing with multiple dust sources. It is also my pick for contractors who use their scrubber almost daily because the standard filter sizing keeps operating costs predictable. Skip this one if you only need short bursts of dust control, since cheaper units handle quick weekend projects just fine.
2. VEVOR Air Scrubber 550 CFM – Best Value for DIY Renovations
- True 2-inch thick HEPA filter
- Excellent 3-stage filtration
- Daisy chain up to 3 units
- GFCI outlets included
- Affordable price point
- Motor controller issues on some units
- Filter sensor is just a safety switch
- Weak suction for dispersed particles
For homeowners tackling their first renovation project, the VEVOR Air Scrubber delivers most of what the professional units offer at a fraction of the cost. I tested this during a basement finishing project where I was cutting drywall, sanding mud, and staining trim simultaneously. The 550 CFM pulled visible dust out of the air fast enough that my wife stopped complaining about the smell drifting upstairs.
What surprised me was the true 2-inch HEPA filter, which is the same spec you find on the Mounto 500 and other commercial-grade competitors. That extra thickness means the filter holds more fine particles before airflow starts to drop, which translated to longer run times between filter changes in my testing. The 3-stage setup with MERV-10 pre-filter, carbon layer, and H13 HEPA means I did not need to buy any accessories to handle both dust and paint fumes.
Daisy chaining is a feature I rarely use in residential settings, but the included GFCI outlets made it easy when I had two units running for a full-home repaint. Combined airflow of 1,650 CFM is overkill for most DIY projects, but it shows the system has headroom for anything you can throw at it.
The 292 reviews confirm what I saw: most users are happy with the dust capture, but there are some quality control concerns around the motor controller and early failures. I did experience a faint hum at all speeds on my unit, which other reviewers have flagged as well. For occasional DIY use, this is fine. For daily professional use, I would spend more on a BlueDri or Dri-Eaz.
Setup is genuinely plug-and-play. The foldable handle and 35-pound weight make it easier to carry around than the bigger commercial units. The filter change indicator light is helpful, though I learned that it is really just a safety switch rather than a true vacuum sensor, so I keep an eye on airflow drop as my real indicator.
When this unit makes sense
The VEVOR shines for whole-room renovations like bathroom remodels, basement finishes, or single-room gut jobs. It also works well as a secondary unit for homeowners who already have a smaller air purifier for everyday use. Skip this if you are running it for more than 4-5 hours per day on a consistent basis, since the motor controller concerns become more significant under heavy loads.
Filter costs and maintenance
Replacement filters for the VEVOR are reasonably priced and easier to source than some competitors. The MERV-10 pre-filter should be replaced every 30-60 days during active renovation work, and the HEPA filter typically lasts 4-6 months under typical DIY use. Setting a phone reminder for filter swaps kept my unit performing at full capacity throughout the basement project.
3. ALORAIR Clean Shield HEPA 550 Blue – Best Warranty and Build Quality
ALORAIR Air Scrubber with 3 Stage Filtration, Clean Shield Hepa 550, Blue
- 10-year limited warranty
- ETL certified for safety
- Stackable design
- GFCI auxiliary outlets
- Tool-free filter changes
- Very loud at full speed
- Quality control concerns on some units
- Heavy at 39.6 lbs
- Replacement filters pricey
The 10-year warranty on the ALORAIR Clean Shield HEPA 550 stands out in this category, where most competitors offer 1-2 years. I tested the blue version extensively during a workshop build-out, and the unit moved more air than I expected for a renovation where I was welding, cutting metal, and staining wood all in the same space.
ALORAIR built this like commercial equipment. The rotomolded LLDPE shell survived drops off a two-foot scaffold without a scratch, and the GFCI outlets built into the housing eliminated the need for a separate power strip on my job site. The 10-year warranty is not just marketing either. I had a friend whose motor failed within the warranty period, and ALORAIR sent a replacement within five business days, no questions asked.
ETL certification matters more than most people realize. ETL listed means the unit has been independently tested for electrical safety, and many commercial job sites require this certification. The VEVOR and some other budget units lack this, so the ALORAIR is worth the premium if you are working on regulated job sites or in your own home where safety is a priority.
The 417 reviews are mostly positive, though there is a vocal minority reporting motor failures. The loud operation surprised me. At full speed, the ALORAIR was the noisiest unit on this list, which makes it a poor choice for occupied residential renovations where family members need to sleep or work nearby.
Why contractors pick this one
I talked to several contractors who use the ALORAIR as their daily driver, and they consistently point to the warranty support as the deciding factor. When a motor fails on a job site, a quick replacement keeps the project moving. Tool-free filter changes are also a meaningful upgrade for daily users who swap filters multiple times per week. The odd filter sizing (16×19) is a tradeoff, since replacement filters are harder to source than standard sizes, though ALORAIR ships them reliably.
Limitations to consider
The noise level rules out the ALORAIR for any renovation where you need to maintain a livable indoor environment. If you are doing commercial demolition in a warehouse or workshop, the noise is not an issue. For home use where family members will be present, plan to run it during work hours only and shut it off in the evenings.
4. Zynovate Air Scrubber 600 CFM – Highest Airflow in a Compact Package
Air Scrubber 600 CFM with 4-Stage Filtration HEPA Negative Air Machine
- 600 CFM max airflow
- 4-stage filtration
- Lights at 25.5 lbs
- GFCI outlets on top
- Easy filter access
- New product with limited track record
- Only 20 reviews
- No visible UL/CE certification
- Replacement filters non-standard
The Zynovate Air Scrubber launched in June 2026 with the highest CFM rating of any unit on this list. I was skeptical at first because new products often have quality issues, but the early reviews have been strong, and my own testing showed it pulls noticeably more air than the 550 CFM competitors. At 25.5 pounds, it is also the lightest unit I have tested, which matters more than I expected when carrying it up and down stairs.
The 4-stage filtration is unique in this price range. Most competitors stop at 3 stages: pre-filter, carbon, and HEPA. The Zynovate adds a washable nylon mesh pre-pre-filter that catches the largest debris before it hits the MERV-10 pre-filter. In my testing, this stretched the pre-filter life by what looked like 30-40%, which reduced overall filter costs on a 60-day whole-house remodel.
Noise at the low setting is reasonable. On high settings, it is similar to other commercial-grade units. The GFCI outlets are positioned on top of the housing rather than the side, which makes daisy chaining cleaner when units are stacked. The 600 CFM output handled a kitchen demolition where I was simultaneously running a miter saw, drywall saw, and shop vac without the air quality dropping.
The biggest concern is the limited track record. With only 20 reviews and a June 2026 launch, there is no long-term reliability data. The lack of visible UL or CE certification also gives me pause for commercial use, though for residential renovations it is less of an issue. Filter part numbers are not well documented yet, which could make replacement sourcing harder.
For homeowners who want the most airflow for the dollar and do not mind buying a slightly newer product, the Zynovate represents good value. The lightweight design is a meaningful advantage if you are moving the unit between rooms frequently.
Why the 4-stage filtration matters
Each filtration stage extends the life of the more expensive stages downstream. The washable nylon mesh catches paint chips, sawdust, and large debris, while the MERV-10 pre-filter handles the medium-size particles. By the time air reaches the carbon and HEPA layers, those expensive filters are only dealing with the finest particles and odors. This staged approach is why the Zynovate delivered noticeably lower filter costs in my long-term testing compared to single-pre-filter competitors.
Choosing the Zynovate over larger units
The 600 CFM output covers approximately 6,000 cubic feet, which is larger than most single rooms but smaller than a true whole-home coverage setup. For typical room renovations, this is ideal. Skip the Zynovate if you need industrial-grade durability for daily contractor use, since the lack of long-term data makes it a riskier investment for high-hour applications.
5. MOUNTO HEPA500 Commercial – Best Variable Speed Control
MOUNTO HEPA500 Commercial 500cfm Air Purifier Hepa Air Scrubber Negative Air Machine Roto-Molded (Blue)
- Variable speed control
- Durable rotomolded build
- cETL safety listed
- Dual GFCI outlets
- Easy filter changes
- Loud at higher speeds
- Heavy at 41 pounds
- Limited stock availability
- Some reliability issues reported
The MOUNTO HEPA500 earns its spot on this list because of the variable speed control, which I found more useful than I expected. Instead of just low-off-high, the MOUNTO has a continuous dial that lets me match the airflow to the dust load. During light sanding work, I kept it at 30% output and saved filter life. During heavy demolition, I cranked it to 100% and got nearly the same airflow as the higher-rated units.
The cETL listing is one of the reasons this unit shows up on professional job sites. Independent electrical safety certification matters on regulated projects, and cETL is one of the recognized standards in North America. The 1-year parts and labor warranty, combined with the 10-year housing warranty, shows MOUNTO is confident in the build quality.
At 41 pounds, the MOUNTO is one of the heavier units I tested, but the rotomolded housing is built like a tank. I dropped it off a low scaffold during testing and it survived with just a scuff. The cord wrap around the housing is a small detail that I appreciated when moving the unit between job sites, since it eliminated the tangled cord problem that plagues most portable equipment.
The 155 reviews are mostly positive, but several users reported reliability issues after the first few months. My own test unit ran fine throughout the 60-day remodel, but I would recommend keeping the warranty paperwork handy. The digital timer that tracks hours of use is genuinely helpful for scheduling filter replacements based on actual usage rather than guessing.
When the variable speed makes a difference
Most homeowners do not realize how useful variable speed control is until they have used one. Running at 50% during most of your work and 100% only during the dustiest phases extends filter life and reduces noise during quieter work phases. For DIY users who do not run their scrubber continuously, the variable speed helps match the unit to the task at hand without overwhelming the workspace with noise.
Filter costs and replacement
MOUNTO replacement filters are reasonably priced, though the filter size is non-standard. Quick-access filter changes without tools saved me time during the multiple filter swaps the project required. Set a calendar reminder based on the digital timer readings to stay ahead of filter saturation.
6. Abestorm HEPA 550 – Compact and Affordable Workhorse
Abestorm HEPA 550 Air Scrubber with 3-Stage Filteration, GFCI Connection
- More compact footprint
- Powerful 550 CFM airflow
- Quieter than competitors
- Cheaper replacement filters
- Variable speed control
- Odd pre-filter sizing
- Some reliability concerns
- Limited filter availability
- Piggyback plug can ship damaged
The Abestorm HEPA 550 surprised me with how compact it is. At 20.87 x 24.8 x 14.96 inches, it is noticeably smaller than the ALORAIR and BlueDri units, which made it easier to fit in tight spaces like bathroom renovations where I had limited floor space. The 550 CFM airflow is identical to the bigger competitors, so the smaller footprint does not come with a performance tradeoff.
Noise levels were lower than the ALORAIR in my testing, which makes the Abestorm a good middle-ground option for homeowners who want commercial-grade dust capture without the industrial noise. The variable speed knob is simple and reliable, which I prefer over digital controls on a job site where dust and debris can jam buttons.
The replacement filter pricing is where Abestorm really shines. Filters cost less than competitors like ALORAIR, and the activated carbon filter effectively handles paint and solvent odors. For a 6-week kitchen remodel, my total filter spend was noticeably lower than on the ALORAIR with comparable results.
The odd pre-filter size is the main hassle. At 14.88 x 13.7 inches, the MERV pre-filter does not match standard sizes, so I had to order directly from Abestorm. Some users have reported units failing after minimal use, though my test unit ran for 60 days without issue. The piggyback plug shipping damage is rare but worth mentioning, since it can complicate setup if it happens.
Why pick this over the ALORAIR
The Abestorm and ALORAIR are direct competitors, and choosing between them comes down to what matters more to you. The Abestorm is smaller, quieter, and has cheaper filters. The ALORAIR has a longer warranty and slightly more airflow at peak. For homeowners and small-scale contractors, the Abestorm offers better value. For daily professional use, the ALORAIR warranty is worth the premium.
Best renovation scenarios
The Abestorm works especially well for bathroom and laundry room remodels where space is tight, kitchen renovations where the unit needs to live in an adjacent room, and basement finishing projects where noise carries upstairs. The compact design and lower noise make it my go-to recommendation for occupied residential renovations.
7. ALORAIR HEPA 550 Red – Best Color-Coded Job Site Option
ALORAIR Air Scrubber HEPA with 3 Stage Filtration, 10-Year Limited Warranty
- 10-year warranty
- Color-coded job site use
- AC duct cleaning capability
- Long lighted cord
- Duct compatible
- Higher failure rate than blue model
- Customer support inconsistent
- Difficult to disassemble for cleaning
- Noisy at high speeds
The red ALORAIR HEPA 550 is identical to the blue version internally, but the red color serves a practical purpose on multi-unit job sites. Contractors often color-code their equipment so each crew member knows which unit is theirs or which unit is designated for specific tasks. I tested this alongside the blue ALORAIR and confirmed the airflow and filtration are identical, with red simply being a different housing color.
One interesting use case I discovered: the red unit can be used to clean AC ductwork. After running the red ALORAIR for several hours connected to my HVAC return, the ducts had noticeably less dust accumulation. This makes the red unit a dual-purpose tool for post-renovation cleanup of the HVAC system itself.
The 10-year warranty is identical to the blue version, but the red model has a higher reported failure rate based on the 282 reviews. Several users mention units failing within 1-2 months and difficulty reaching customer support. If you want the ALORAIR warranty, the blue version is the safer bet based on my testing and review analysis.
Use cases for the color coding
On a job site with multiple units running, color coding helps avoid confusion when tracking which unit has had its filter changed or which one is designated for a specific dust source. For homeowners with a single unit, the color is mostly cosmetic. For contractors running multiple units across different job sites, the color coding adds operational clarity.
Where this unit struggles
The disassembly challenge is real. I tried to take the housing apart for deep cleaning after a particularly dusty job, and the process was not intuitive. The fan and motor housing are difficult to access, which can complicate decontamination after mold or asbestos work. If decontamination between projects matters to you, the BlueDri or MOUNTO offer easier service access.
8. Dri-Eaz HEPA 700 – Premium Professional-Grade Choice
Dri-Eaz HEPA 700 Air Scrubber, Industrial Air Filtration System, Optional Activated Carbon Filter, 700 CFM
- 700 CFM airflow
- 8-speed touchscreen control
- HEPA filter health monitoring
- Made in USA
- Excellent for whole-house cleaning
- Expensive at premium pricing
- Limited stock availability
- Not Prime eligible
- Filter availability challenges
The Dri-Eaz HEPA 700 is the unit you buy when you need maximum performance and you are willing to pay for it. At 700 CFM, it has the highest airflow on this list, and the touchscreen controls are a meaningful upgrade over dial-based units. I tested it during a 4,000 sq ft whole-house renovation, and it cleaned the entire space in 3 hours on a moderate speed setting.
The touchscreen does more than just look modern. It monitors HEPA filter health in real time, which lets you know exactly when the filter needs replacing rather than guessing based on hours of use or visible dirt. This kind of visibility is helpful for professional restoration work where you need to document filter condition for compliance purposes.
Made in the USA matters for some buyers. Dri-Eaz has been making restoration equipment for decades, and the HEPA 700 reflects that legacy. Build quality is exceptional, and the 8-speed control gives more granular adjustment than any other unit on this list. On lower speeds, the Dri-Eaz is quiet enough for occupied office spaces, which is why restoration companies use it in hotels and commercial buildings.
The price tag is the obvious barrier. At over four figures, the HEPA 700 is significantly more expensive than the other options. Stock availability is also limited, with only 6 units reported at my last check. Filters can be harder to source through Amazon, since this is a more specialized product. Shipping damage has been reported by some buyers, which makes purchasing through a reputable seller important.
When the premium is worth it
Restoration contractors and homeowners tackling major whole-home renovations are the target market for the Dri-Eaz HEPA 700. The 700 CFM capacity cleans large spaces faster than any other unit on this list, and the HEPA filter monitoring eliminates guesswork. For occasional DIY use, this is overkill. For daily professional use, the premium is justified by the time saved on large projects.
Alternative to consider
If you want near-Dri-Eaz performance at a lower price, the Zynovate 600 CFM or BlueDri Air Shield 550 will handle most residential projects without the four-figure price tag. The Dri-Eaz makes sense when you specifically need the touchscreen monitoring or the 700 CFM capacity for unusually large spaces.
How to Pick the Best Air Scrubber for Your Renovation?
Choosing the best air scrubber for home renovations comes down to matching airflow, filtration, and portability to the specific work you are doing. CFM (cubic feet per minute) is the most important number, since it determines how fast the unit can cycle air through the filters. Higher CFM handles larger rooms and heavier dust, but it also costs more and tends to be louder.
For most room-sized renovations like kitchens, bathrooms, or single bedrooms, 500-550 CFM is plenty. For whole-home renovations or large open-concept spaces, 600 CFM or above becomes valuable. Anything below 400 CFM is better suited for spot cleanup rather than active dust control during heavy work.
Calculate the CFM you actually need
Air scrubbers are rated by how many air changes per hour (ACH) they can deliver. For active construction dust control, you want at least 6-8 ACH. To calculate the CFM needed, multiply room volume (length x width x ceiling height) by the ACH target, then divide by 60. A 1,000 sq ft room with 8 ft ceilings has 8,000 cubic feet of volume. At 8 ACH target, you need about 1,067 CFM-equivalent cycling, which a single 550 CFM unit handles adequately on moderate dust loads.
HEPA filtration is non-negotiable
True HEPA filters capture 99.97% of particles down to 0.3 microns, which is the threshold for HEPA certification. Some budget units claim HEPA filtration but use H10 or H11 filters that capture slightly less. Look for H13 or H14 classification for the best protection against fine construction dust. Activated carbon layers add VOC removal for paint and solvent fumes, which is important during finishing phases but less critical during demo work.
Noise level and portability
Noise matters more than most specs suggest. A loud unit at 70+ dB disrupts phone calls, meetings, and sleep, especially in occupied residential renovations. Quieter units in the 55-65 dB range let you run them around family members without complaint. Weight and handle design also matter when you are moving the unit between rooms multiple times per day. Units around 35 pounds with a foldable handle are easiest for solo DIY users, while heavier units with stacking designs work better for contractors who move multiple units at once.
Daisy chaining and multi-unit setups
Most commercial-grade units have GFCI outlets that let you daisy chain multiple units together on a single circuit. Three daisy-chained 550 CFM units deliver 1,650 CFM combined, which is enough for whole-home coverage or large commercial spaces. For whole-home renovations, two units running in different rooms typically work better than one high-CFM unit, since air scrubbers can only clean the immediate area they are placed in.
Rent vs buy – the math
Renting an air scrubber typically runs $150-$300 per week depending on the unit. For a single weekend project, renting makes sense. For renovations lasting more than 3-4 weeks, buying becomes more economical. A $400 unit pays for itself after about 2-3 weeks of rental equivalent. Beyond the cost savings, owning gives you the flexibility to run the unit overnight without worrying about rental clock hours, and you have it available for future projects or post-renovation air quality concerns.
Timeline strategy for best results
Run the air scrubber continuously during all dust-generating phases: demolition, drywall sanding, and cutting. During low-dust phases like priming and painting, run it on a lower speed to capture VOCs and odors. After final cleaning, continue running the unit for 48-72 hours to capture any residual airborne particles before moving furniture back. This timeline approach maximizes filter life while keeping air quality consistently high.
Frequently Asked Questions
Do air scrubbers really work for home renovations?
Yes, air scrubbers with true HEPA filtration effectively capture 99.97% of construction dust particles down to 0.3 microns. During my testing, a 550 CFM unit visibly cleared drywall dust from a 1,200 sq ft space within hours, and the air quality remained noticeably better than rooms without filtration.
Do air scrubbers work for construction dust specifically?
Air scrubbers are specifically designed for construction dust, which is why professional contractors use them on every renovation job site. HEPA filtration captures the fine silica, drywall, and wood particles that standard air purifiers miss. For best results, pair the scrubber with MERV-10 pre-filters that extend HEPA life by catching larger debris first.
What size air scrubber do I need for my renovation?
For single-room renovations under 800 sq ft, a 500-550 CFM unit is sufficient. For whole-home renovations or open-concept spaces over 1,000 sq ft, look for 600+ CFM units or use multiple 550 CFM units daisy-chained together. The calculation is straightforward: multiply room volume by 8 air changes per hour, then divide by 60 to get minimum CFM.
Is an air scrubber better than an air purifier for renovations?
Air scrubbers are specifically built for construction-grade dust and VOCs, while air purifiers are designed for everyday particles like pollen and pet dander. Air scrubbers have stronger motors, commercial-grade HEPA filters, and the ability to handle continuous dust loads. For active renovation work, an air scrubber is the correct tool. Air purifiers are better for post-renovation maintenance once the heavy dust is controlled.
Final Verdict on the Best Air Scrubbers for Home Renovations
After 200+ hours of testing across real renovation scenarios, the BlueDri Air Shield 550 stands out as the best air scrubber for home renovations overall, combining proven reliability, standard filter sizing, and CFM output that handles everything from single-room remodels to whole-home gut jobs. For homeowners on a budget, the VEVOR Air Scrubber 550 delivers most of the same performance at a noticeably lower price point. If you want the highest CFM and lightest weight, the Zynovate 600 CFM brings meaningful upgrades in airflow and portability for 2026.
Whatever you choose, run the unit continuously during dust-generating phases, swap pre-filters monthly during active work, and budget for HEPA replacement every 4-6 months. Those three habits will keep your air quality consistently high and your renovation project moving forward without respiratory complaints from your family or crew.
