Furnace Filters

Your filter’s thickness is key to a good fit for your HVAC system.

Ensuring that your filter fits properly in your HVAC system means making sure that you have not only the right length and width, but also thickness of your filter. Most standard air filters are 1 to 2 inches in thickness, whereas media filters are typically 3 to 5 inches in thickness. The best way to measure your air filter size is to get out the measuring tape and measure it directly.
