While half is a true HEPA filter that captures particulates as small as 0. 3 micron at a rate of 99. 97%, the second half uses activated carbon to remove odor and volatile organic compounds from the air. The entire filter features an antimicrobial treatment that prevents the growth of mildew, bacteria, and fungi, eliminating the resulting odor. Everything
