About HEPA Air Scrubbers

Ever wondered how air gets cleaned? The answer is in air scrubbers. An air scrubber removes pollutants from the air and improves overall air quality. The pollutants are scrubbed from the air with a HEPA air filter. HEPA filters are the most heavy-duty filters available and can remove up to 99.97% of airborne particles such as:

  • Mold
  • Dust
  • Pollen
  • Bacteria
  • Lead
  • Asbestos
  • Or any particles that are 0.3 microns in size

Air scrubbers work by circulating air through the machine continuously. A blower sucks the air in and the HEPA filters capture and remove any contaminants. Next, the newly clean air is released back into the room. As the air scrubber continues to work, the air gradually goes from being filled with particles to being clean. Air scrubbers can be used in a variety of settings and are valuable machines that can be utilized for water damage restoration projects. Using a HEPA air scrubber ensures clean air which can lead to better health and quality of life.

Components Of An Air Scrubber

There are four components of an air scrubber. Let’s explore what makes an air scrubber work.


When air first flows into the air scrubber, it’s met with pre-filters. These pre-filters can catch any larger particles. Removing larger particles first allows the air scrubber to function efficiently and effectively.

Carbon Filter

The carbon filter in an air scrubber is designed to trap odors using adsorption. The carbon in the filter attracts the gas in the odor molecules and traps them. Once air comes back out of the air scrubber, it should smell fresher.

Primary Filter

The main component of an air scrubber is the primary filter. In a HEPA air scrubber, the primary filter is the HEPA air filter, but this type of filter can vary for different air scrubbers. Since the pre-filter has removed the larger particles and the carbon filter has removed the odor molecules, all that’s left is for the primary filter to remove the smallest particles.

Blower Motor

The blower motor has two functions in an air scrubber. It sucks the air in and releases purified air back out. The blower motor and filters work in tandem. A blower motor that has too much power will actually decrease the efficiency of a HEPA air scrubber since the filters will not be able to keep up with the pace of the air being filtered inside.

How to Repair Water Damage to Your Drywall & Ceiling

What Are Air Scrubbers Used For?

Air scrubbers can be a valuable tool in plenty of industries. Anywhere with decreased air quality can benefit from having a portable HEPA air scrubber purify the air. Here are just a few examples of times when air scrubbers could be used.

Restoration Projects

Are you having your home or business restored following water damage or mold? The restoration company is probably using an air scrubber to help clean the air.

Water Damage

Water damage can lead to humidity and the development of mold in your home or business. Dehumidifiers can suck any lingering water from the air. Next, HEPA air scrubbers can be used to clean any bacteria that could be left.


When buildings have mold, the health and well-being of anyone who lives or works there could be compromised. Mold grows in areas with high humidity or if water has been sitting. Once mold has been properly removed, air scrubbers help filter the air so any bacteria is caught.

Medical Settings

HEPA filters are commonly found in hospitals since they remove such high amounts of particles from the air. HEPA air scrubbers can be used in situations where hospitals or health care facilities lose power or the buildings are undergoing air quality issues.

Construction Projects

Active construction sites can have dust and airborne particles like chemicals and gases flying through the air. HEPA air scrubbers are the perfect way to purify the air on those sites and keep construction workers healthy.

Are Air Scrubbers and Air Purifiers the Same?

While air scrubbers and air purifiers accomplish similar goals, both types of systems are different. Air scrubbers are systems that can remove particles or gasses from the air. Air purifiers only use filters to clean the air. Air purifiers can only clean airborne particles. On the other hand, air scrubbers can clean airborne particles and surfaces in the room as well.
