Choosing the Correct Filter Size

Nominal Size vs. Actual Size

The nominal size is a shorthand number rounded to the nearest whole or half inch, typically in a larger font (ex: 16 x 20 x 1). The actual size is the precise measurement, typically in a smaller font, that represents the filter's exact dimensions (ex: 15.50 x 19.50 x 0.75). All filters have both.

Measuring Your Air Filter

If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width x length x depth to determine the actual size. Round these measurements up to the nearest inch to find the corresponding nominal size, which will be easier to find when searching online.

Why Should I Change My Air Filter?

To maintain a healthy lifestyle, as breathing dirty air can increase the risk of developing asthma, allergies, and other respiratory ailments. Additionally, old filters can cause system defects that may lead to higher energy costs and repairs.

When Should I Change My Air Filter?

We generally recommend replacing your filter every 90 days to keep your system running efficiently and the air clean. However, this can vary based on filter size and specific factors such as pet owners, allergy sufferers, homes with children, etc.

Will These Air Filters Fit My System?

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 correct size. However, if you see a specific brand name on a listing, make sure it matches your unit model.

How Many Air Filters Do I Need?

This varies for each customer depending on specific needs, such as the number of vents in your home. Our selection includes package quantities ranging from 1 to 12 filters, so no matter your situation, we've got you covered.

How Do I Change My Air Filter?

After finding the right size, turn off the power supply and remove the cover from your intake vent. Take out the old filter and insert the new one to match the direction of air flow. Then replace the cover and turn the power back on.
