How Do Air Scrubbers Remove Mold Spores From the Air?

A commercial air scrubber for mold follows the principle of negative airflow. In simple terms, negative airflow removes air from an enclosed space. 

Air scrubbers typically come with three-stage HEPA negative air filters. The powerful fans of air scrubbers suck ambient air into it and purify the air using a series of filters. 

Different filters trap specific air pollutants, while HEPA traps and removes mold spores from the air. In the end, after purifying the air, air scrubbers transfer the air back into the room or vent it outside.

Do Air Scrubbers Create Ozone?

No, most air scrubbers do not generate ozone. Ozone is an irritating gas that can cause breathing problems.

What Kind of Air Filter Removes Mold Spores?

Air scrubbers are available with HEPA filtration, which helps trap mold particles with excellent efficiency. HEPA filters are made with a thick sheet of tiny fibers sealed in a plastic or metal frame and are able to capture almost every kind of particulate matter in the air.

Certified HEPA filters effectively remove the particles down to the size of 0.3 microns. Mold spores are usually larger than that, at about 4 to 20 microns in size

Air scrubbers have fans that draw in the air containing mold into the HEPA filter, which is able to trap the molds and release fresh air that is safe to breathe back into the space.

Final Thoughts

Molds can be very harmful to your breathing. Running a commercial air scrubber through your place of work or home can help remove molds, making these places safer for you to breathe. As we explained, air scrubbers use HEPA filters to remove tiny mold spores from your air, sucking them into the filter and then venting out the clean air into the space.
