A filtered fresh air intake system adds fresh air to a home heating and cooling system. This improves indoor air quality by diluting polluted or stale indoor air and also pressurizes the home to help keep pollutants out.
Most residential systems use the HVAC air handler fan to pull in clean outside air from a duct through the wall or attached to a foundation vent. The air is filtered just before it enters the air handler and mixed with the return air and then dispersed evenly throughout the building through the supply duct system.
Fresh air enters the duct before the air handler fan which reduces the volume of return air being pulled from inside the home. Since the supply air exceeds the return air, a positive pressure is maintained in the home when the HVAC system is in operation. Positive pressure reduces infiltration of outside air from undesirable locations and helps keep irritants and other pollutants from entering the home.
Filtered fresh air intake system benefits include:
- Cleaner, fresher smelling home with less dust
- Helps prevent chemicals, pesticides, pollen, mold spores and other pollutants from entering home
- Reduces drafts from windows and doors as well as back-drafting
- Adds air to the home to replace air exhausted by clothes dryer, bathroom exhaust fans and range hood vent.
A filtered fresh air intake system is sometimes referred to as passive ventilation as it doesn’t require electricity, it’s quiet and inexpensive to operate. Passive ventilation is also low-maintenance because it doesn’t have moving parts and the only maintenance needed is periodical cleaning of the filters.
Most newer homes are well insulated and almost airtight. While that is great for lowering heating and cooling costs, it can lead to poor indoor air quality and an unhealthy home environment.
McKee Homes includes a filtered fresh air intake system to all our new homes greatly improving the air quality and minimizing indoor pollutants making our homes environment healthier and more comfortable.
