Why risk your health when IQAir offers proven protection and no harmful byproducts? Certified results, in writing IQAir tests every HealthPro Plus system at our Swiss factory to ensure its performance meets our strict specifications. We test Total System Efficiency – the actual air coming from the outlet. The results are detailed in a hand-signed Certificate of Performance shipped in the box with every IQAir air purification room system. The HealthPro plus contains three filters: PreMax Pre-Filter (F1), V5-Cell, and HyperHEPA Filter to provide the most reliable air purification combination on the market. First is the PreMax Pre-Filter traps micro-particles such as dust, mold spores, and powder. The V5-Cell (F2) controls gases & odors. Patented V5-Cell filtration provides the best solution for gas & odor control. The V5-Cell prevents gas & odors by combining two types of media: one adsorbs odors & gases, the other changes pollutants to an oxidized form. Lastly, the HyperHEPA (F3) filter traps fine and ultrafine particles, pathogens, viruses, and highway exhaust particles. The clean air is then expelled through the EvenFlow diffuser and distributed throughout the room.
