The 6 Best HEPA Air Scrubbers For Renovation Projects [Updated for 2022]
One of the biggest downsides of any renovation, remodeling, or construction project is the amount of air pollution caused by the work. Everything from sawdust to paint fumes to insulation can cause air irritants that disrupt people in the house, particularly if they have asthma.
In addition, your remodeling project may be the result of some kind of damage to the house. Whether you’re eliminating mildew and mold or restoring fire damage, you’re going to kick up some manner of spores, dust, or charcoal in your work.
This is what makes a HEPA air scrubber such an important addition to your home environment. Air scrubbers are filtration units that suck in the air in your house, process it through filters, and send it back out free of contaminants like gasses, particles, and chemicals. Sewage-derived bacteria and spores from mold can have a huge negative impact on your health.
It only makes sense to invest in a HEPA air scrubber to keep you and your family’s breathing air free of particles and contaminants. Here is a short guide to some of the best air scrubbers on the market, including the features of each one and our recommendations.
The all-purpose air cleaner by BlueDri is our top pick for HEPA air filters because of its versatility and performance.
It’s equipped to purify an entire home of not only chemicals and pollutants but also asbestos particles, sawdust, pet dander, mildew, pollen, and other irritants. This makes the BlueDri Negative Machine a great choice not only for those concerned about chemicals and mold but also for those with allergies.
Pets, painting projects, and cooking can also leave terrible smells in the house that can irritate your sinuses or even harm people’s systems (especially if there are young babies in the house). BlueDri comes with an optional odor eliminator (sold separately) that makes it a great choice to clear out bad smells from a litter box or to keep your salon from smelling like nail polish all day.
Whether you’re looking for an air scrubber to remove mold contamination or to remove pet smells, BlueDri’s three-stage filtration system is an easy choice.

The BlueDri Negative Airbourne Cleaner is our pick for the best HEPA air scrubber on the market.

What is an air scrubber used for?
Air scrubbers are used for any project in the home that requires air cleanup. This includes construction jobs, remodeling and renovation, sewage remediation, painting, fire and water restoration damage, and mold removal.
In addition, there are many natural pollutants that an air scrubber can remove outside of big projects. For those susceptible to allergies from pet dander or pollen, air scrubbers can help get even large particles out of circulation in your home. Smoke, smells from chemical cleaners, pollen, dust, or even litter box smells are all issues that can be addressed with the right air purifier.
How does an air scrubber work?
An air scrubber works by using a multi-stage filtration system to process the air that it sucks into its mechanism before re-dispersing back into the home or work area.
The first stage is a pre-filter that traps any larger particles. These include dander, sawdust, or any other tangible airborne irritants. Then, a HEPA filter processes the air to remove chemical irritants, mildew, mold spores, and other contagions from the air. An optional odor-filter can also process air for smells from pets, mold, paint, or other irritants.
The air scrubber then sends the air back into the room and continues doing this at whatever speed you set on the control dial that most units have.
At this point, we can probably agree that your renovation project or daily household air quality could probably use a quality air scrubber. However, what makes an air scrubber high quality depends both on your needs and on the capabilities of your machine. Here are a few main factors to think about before buying your air scrubber.
Make sure it has a multi-stage filtration system that includes a pre-filter, HEPA-filter, and optional or included odor control filter.
Since you’re going to be using this on construction sites or in remodeling projects, you want to make sure that your unit has a durable frame. Check the material construction and make sure that it’s sturdy enough to withstand a little beating without cracking.
Know that if you’re going to be using this for a bigger project, you may need to link multiple units together. Check how many units can be chained to your specific model and also how much air space the scrubber is intended to purify to make sure that it has enough power to finish the job you need.
If you have pets or pollen in your house, make sure the filter lists your specific irritant as one that the filtration unit covers. Some have nylon filters that conveniently collect dander and can be washed by hand.
Other amenities like the length of the cord should be considered if you know the layout of your project. Not all sites have immediate access to a power outlet so buy accordingly.
An air scrubber is an essential piece of equipment on any construction site, remodeling job, or damage repair worksite. Many of us don’t realize that airborne pollutants in our home constitute the most pollution any of us will ever breathe. This includes dust, mildew, mold spores, paint, asbestos, smoke, chemical cleaners, and many other irritants.
Taking care of these pollutants with an industry-grade air scrubber like the BlueDri Negative Machine Airborne Cleaner will make you and your family safer, particularly if there are old or young people in your home.
