We spend on average over 90% of our time indoors, so air quality is a primary consideration when installing your system. The Infinity™ Air Purifier provides impressive filtration efficiency at low pressure, for reduced energy consumption. It traps and kills all viruses, bacteria and allergens. It requires no cleaning and alerts you when it’s time to change the filter. Air purifiers and air filters not only add to your comfort, they provide better efficiency, durability and performance for your system.
