Find your filter

Not sure what size filter you need? Here are three easy ways to find out:

· Check your current filter

Pull out your existing filter — the size is usually printed right on the edge (like20x25x5).

· Know your HVAC brand

Sometimes, knowing the brand and model of your heating or cooling system can help identify the right filter size.

· Measure it yourself

Use a tape measure to check the length, width, and thickness in inches. Round to the nearest whole number.
