How does the AirMac-400H Portable HEPA Air Purifier Work?

The AirMac-400H portable HEPA air purifier is a powerful, 3-stage filtration system designed to capture the smallest, most inconvenient pollution particles and offensive odors.

  1. Stage 1 - Pre-Filter - The Pre-Filter is a metal mesh screen designed to capture larger dust and particles and to prolong the life of the HEPA filter. It's washable and should be checked periodically for cleaning. After several cleanings, it should be replaced when showing signs of wear & tear.
  2. Stage 2 - True HEPA Filter - The HEPA filter in the AirMac 400H is 99.97% efficient at capturing particles 0.3 microns in size. This is REALLY small! The HEPA filter is a commercial-grade filter with a 26 gauge steel frame. The HEPA filter cannot be washed and should be replaced at least once per year. 
  3. Stage 3 - Carbon Filter - The final stage in the AirMac 400H is the carbon filter. The high volume of carbon in this filter will ensure that odors, gases, and VOCs are removed as the air passes through. With 2 full pounds of activated carbon, this filter will easily tackle those tough odors and gases caused by chemicals, smoke, solvents, paint, ozone, and much, much more!

In an article published by USA Today, "... Microns are small – 1 millionth of a meter. Pollen particles are often 10 microns or bigger. Bacteria are often about 1 micron. COVID19 has a diameter of approximately 60–140 nm or 0.06 to 1.4 microns." The USA Today article goes on to say that the COVID-19 virus itself is indeed smaller than a filter rated the size of 0.3 microns, but the virus always travels attached to larger particles that are consistently snared by the filter. And even if the particles were smaller than the 0.3-micron size, the erratic motion of particles that size and the electrostatic attraction generated by the filter means they would be consistently caught as well.
