IQAir® HEALTHPRO PLUS 1. Includes HyperHEPA™ - The Most Powerful Air Filtration Available. Most air purifiers can only filter down to 0.3 microns in size, but 90% of all particles in the air are smaller than 0.3 microns! IQAir's patented HyperHEPA filtration filters down to 0.003 microns with a guaranteed minimum efficiency of 99%. This means that HyperHEPA can remove up to 100 times more allergens than conventional air cleaners. 2.

Advanced Gas & Odor Control Protect yourself from household chemicals. Common household products like cleaners and detergents can emit dangerous vapors. Some air purifiers filter particles, but not chemicals or gases. IQAir offers the best gas filtration technology to remove the widest range of airborne chemicals. 7. 100% Ozone-Free Technology All IQAir air purifiers are certified to produce absolutely no ozone. Ozone is a lung irritant that is emitted from ionic air cleaners. Even small amounts of ozone are undesirable for allergy and asthma sufferers.
