Whole-home air filtration systems work with your central HVAC equipment to capture dust, pollen, pet dander, and other airborne particles as air circulates. Hoff Heating & AC installs residential air filtration systems in O’Fallon, MO, for different filtration needs and HVAC configurations.

Unlike portable air cleaners that treat one room, a professionally installed system can provide filtration throughout the home. Our technicians evaluate your equipment, airflow requirements, and concerns before recommending an appropriate filter or air cleaner. Filtration can also be combined with other indoor air quality services when your home has multiple concerns.

For homes with concerns beyond particle filtration, whole-home air scrubber systems provide another indoor air quality option.

Whole-Home Air Filtration System FAQ

What MERV rating is best for a whole-home air filtration system?

A higher MERV rating captures smaller particles, but the best rating depends on your HVAC system’s airflow requirements. A technician can help you select a compatible filter. Homes needing additional contaminant or odor control may also benefit from whole-home air purification.
