Dilution
Replaces a portion of the indoor air with fresh outdoor air. This process occurs naturally in all homes, but at different rates depending on the structure's tightness. Opening windows is one way to increase the pace of air exchange, although it's an energy-wasting solution. Energy-effient ERV (Energy Recovery Ventilators) exchange indoor air for outdoor air while recovering most of the energy used to heat or cool the air being exhausted. Controlling fresh air entering the home allows it to be conditioined by an efficient air cleaner, dehumidifer and UV Treatment System prior to passing through the home's air handler or air conditioner.
