vs. the competition

Ozone generators are known to eliminate odors, but studies show that ozone emission may be harmful to the health of both humans and animals. QAIS-air-® products are certified by CARB (California Air Resource Board) for ozone emission standards, so you can safely place your air purifier by your pet’s bed, litter box or favorite spot without worry.

HEPA filters are said to remove 99.97% of airborne particles sized 0.3 microns or greater. But odor molecules are much smaller that (about 0.001 microns) which means that HEPA filters aren't actually very effective at combating smells. QAIS-air-® uses PCO technology that decomposes odor-causing compounds regardless of molecule size. Additionally, HEPA filters are more of a hassle, having to be cleaned or replaced regularly to keep up its performance. QAIS-air-® requires no maintenance or replacement of parts.

Air fresheners may cover up stinky smells, but they do not eliminate the compounds that create odors. Pets can be super sensitive, so the aerosol and strong fragrances may actually stress them out. QAIS-air-® eliminates odor by decomposing odor-causing compounds and does not emit any chemicals or strong smells.
