    Product Description

    The IQAir new edition HealthPro Plus is the best choice for asthma and allergy sufferers. IQAir HyperHEPA filtration is proven to trap the smallest, most harmful particles in the air, down to 0.003 microns – 100 times smaller than 0.3 microns. That includes viruses, pet dander, dust mites, air pollution, even cigarette smoke. IQAir nanofiber technology and innovative design stop particles 100x smaller than 0.3 microns. IQAir uses only safe, proven technology to clean the air. IQAir systems produce no unhealthy ozone, ions, UV or chemicals. IQAir tests every HealthPro Plus system at the factory to ensure its performance meets our strict specifications. We test total system efficiency – the actual air coming from the outlet. Results are detailed in a hand-signed Certificate of Performance that is shipped in the box with every HealthPro Plus system. V5-Cell filtration provides the best solution for gas & odor control. The V5-Cell combines 2 types of media: one adsorbs odors & gases, the other changes pollutants to oxidized form. The new edition HealthPro Plus delivers up to 25% more clean air, up to 38% longer filter life, and 32% less sound.
