Choosing the Correct Filter Size It's important to understand the difference between nominal and actual filter sizes to ensure a proper fit for your HVAC system. The nominal size is a rounded measurement, while the actual size is the precise dimension.

Measuring Your Air Filter If your current filter doesn't have a listed size, use a tape measure to record the width, length, and depth, then round up to the nearest inch to find the corresponding nominal size.

Why Should I Change My Air Filter? Changing your air filter regularly is crucial for maintaining indoor air quality, system efficiency, and avoiding costly repairs. Dirty filters can lead to respiratory issues and increased energy bills.

When Should I Change My Air Filter? We generally recommend replacing your air filter every 3 months, but the frequency may vary based on factors like filter size, pet ownership, and allergy concerns.

Will These Air Filters Fit My System? Most of our filters are universally compatible with furnaces, air conditioners, heat pumps, and HVAC systems, as long as you select the proper size. Double-check your unit model if a specific brand is listed.

How Many Air Filters Do I Need? The number of filters required depends on the number of vents in your home. Our selection includes packages ranging from 1 to 12 filters to accommodate various needs.

How Do I Change My Air Filter? Changing an air filter is simple - turn off the power, remove the old filter, insert the new one in the correct direction, replace the cover, and turn the power back on.
