The HealthPro Plus offers up to 25% more clean air, 38% longer filter life and 32% less noise. In fact, it’s now the quietest high-performance air purifier in the world. At the heart of this revolutionary system is the exclusive IQAir HyperHEPA filtration technology that effectively traps particles of all sizes. That includes viruses, pet dander, dust mites, other allergens and even cigarette smoke. While ordinary air cleaners are only tested for the largest 10% of particles, IQAir’s HyperHEPA filtration is tested and certified to filter 99.5% of all particles down to 0.003 microns. These are the smallest particles that exist. Imagine the difference virtually allergen-free air can make to your health. If clean air really matters to you, you’ll love the HealthPro Plus. IQAir is an educational partner with the American Lung Association.
