You can narrow down your furnace filter by a number of ways in including size, MERV rating and or brand.
If you cannot find your filter size in your store, please proceed to the next steps below.
How To Measure Your Custom Furnace Filter's Size
It's important to know the difference between a nominal size and an actual/exact size which we explain it in detail in our Furnace Filter Size Guide. In order for us to make the correct filter for your needs, it's best that you send us the exact size and NOT the nominal size.
If the exact size is not written on your filter, please measure your filter's height, length and thickness in inches as seen in the image below:
Send in your custom size filter request with the size in inches using the contact form on the right-hand side of this page, in this format:
height x length x thickness (example: 14½ x 26¾ x 2½)
Someone from customer service will get back to you with a quote within 24 hours. From there, if you wish to proceed, we will send you an online payment request, once processed, you can expect your custom size furnace air filters delivered within 10-15 business days.
Make sure that you measure the exact dimensions of our furnace filter.
NOTE: There are no refunds/returns for custom fixed furnace filters. Please measure and confirm your exact filter size before purchasing.
