The MicroGuardian Air Scrubber® is the only true in-line HEPA
filter similar to the filters used in hospitals, clean rooms and microchip manufacturing
plants. The HEPA stage of the Micro-Guardian Air Scrubber is engineered to stay
efficient for up to five years, as long as the Carbon Stage and Polyethylene
Foam Stage is replaced every six months.
Single pass efficiency is 85% at .3 microns and 99% at .5 microns. It will remove 50% of volatile organic compounds (VOC) and odors. Large cabinet design (2.5, 3.5 and 5 ton sizes) allows for good air flow. The MicroGuardian AirScrubber has a five-year life on the HEPA filter and six month change on the pre-filter and carbon filter.
