The Austin “it” filter uses medical grade HEPA technology to remove 99.97% of all particles larger than 0.3 microns and 99% of all particles larger than 0.1 microns. This includes particles, dander, viruses, bacteria, molds, spores, and pollen. The “it” HEPA filter is designed to last up to five years under normal residential conditions. 

The Austin “it” HEPA replacement filter can be upgraded to include a dual-stage VOC Carbon Wrap that also adsorbs VOCs, chemicals, gases, and odors. The VOC Carbon Wrap is designed to last three months under normal conditions.
