Choosing the correct filter size is important, as the nominal size is a rounded number, while the actual size is the precise measurement. To find the right size, measure your current filter and round up to the nearest inch.

Changing your air filter regularly is essential for maintaining a healthy lifestyle, as breathing dirty air can lead to respiratory issues. We generally recommend replacing your filter every 90 days, but this may vary based on factors like the number of vents, pets, and allergy sufferers in your home.

At Filterbuy, we are committed to providing better air for all. We are proud to be an American-made company, manufacturing our filters in various locations across the country. We also offer a subscription service to simplify the filter replacement process.
