What Is An Air Scrubber?
Plainly speaking, an air scrubber is a negative air machine (negative pressure) that filters out dust. It’s perfect for all projects that include particulates (dust, smoke, mold mediation, etc.).
Top air scrubbers have a two-stage filtration. Here’s how an air scrubber works:
  1. A big fan creates an airflow; it sucks in dust-full air and vents out dust-free air.
  2. 1st stage: Pre-filtercaptures dust larger particles
  3. 2nd stage: The HEPA filtercaptures 99.97% of the small particlesdown to 0.3 microns.
With the use of filters, an air scrubber generates negative air pressure that prevents cross-contamination.
Here’s why the 2-stage filtration is used:
1st stage prefilters (that are cheap) are there to protect the 2nd stage HEPA filter (that’s expensive).
