Upgrade Indoor Quality in Minutes

The right fit and placement are key to protecting both your system and your health. Replacement of Filterbuy air filters is not a time consuming task. User-friendly design coupled with compatibility across diverse HVAC systems contributes to this convenience.

• Start by turning off your HVAC. This prevents unfiltered air from circulating during the replacement.

• Remove the old filter. Note the airflow direction arrow. This matches the direction of airflow from your return duct toward the HVAC unit.

• Insert your new filter snugly into the slot. The arrow should be facing the correct direction. A loose or backward facing filter reduces efficiency and even early equipment failure.

Remember to replace your filter every 60 to 90 days. You can also sign up for Filterbuy automatic delivery service so you can say goodbye to the hassle of remembering when to replace your air filter.
