The air you breathe in your home is a combination of a multitude of particulates. Particles are made airborne by all kinds of normal activities ranging from cooking, walking on carpet, playing with your pets, or even just getting up off the sofa. Any movement or vibration can create airborne particles – even air moving over an apparently clean surface will pick up particles. Airborne allergens, mold spores, bacteria, and dust mite/insect feces are also present. These particulates are transported through the air and the forced air heating/cooling system to all points in the home. They can be drawn into the respiratory system with each breath, potentially causing sickness and other health issues.
A BROAN Fresh Air System with HEPA (High Efficiency Particulate Air) filtration removes stale air from the home, replaces it with fresh, filtered outdoor air and continuously filters the existing air in the home. The HEPA filtration system uses medical grade filtration to remove airborne particles as small as .03 microns in size. In comparison, a human hair is 100 microns in diameter. BROAN HEPA air exchangers with Heat Recovery or Energy Recovery are also designed to recover heating or cooling energy from outgoing air and transfer it to the incoming air. This provides your home clean, fresh air for pennies a day.
