Why do we love what we do? We take pride in providing a service that helps keep our community healthy. Breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. Regular filter changes help maintain a healthy lifestyle and keep your HVAC system running efficiently, potentially saving you from unwanted energy costs and repairs.

When it comes to filter sizes, it's important to understand the difference between nominal and actual sizes. The nominal size is a rounded number, usually in a larger font, while the actual size depicts the filter's precise dimensions. All our filters have both measurements listed to ensure you find the perfect fit for your system.

To determine the right size, measure your current air filter if it doesn't have the dimensions listed. Then, round up the measurements to the nearest inch to find the corresponding nominal size, which will be easier to locate when searching online.

We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean. However, this timeline may vary based on factors like filter size, pet ownership, allergy concerns, and the number of occupants in your home.

Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system, as long as you choose the proper size. If you see a specific brand name on a listing, make sure it matches your unit model.

The number of filters you need depends on the number of vents in your home. Our selection includes package quantities ranging from 1 to 12 filters, so we've got you covered no matter your situation.

Changing your air filter is a simple process. After finding the right size, turn off the power supply, remove the cover from your intake vent, and take out the old filter. Then, just insert your new filter to match the direction of airflow, replace the cover, and turn the power back on.

At Filterbuy, we're committed to providing the best indoor air quality solutions for your home or business.
