Custom Furnace Filter Sizes

Your Filter Connection is your one stop shop for air conditioner and furnace filters. When we say, “We’ve got your size,” we mean it! If you cannot find the size you need, you can order a custom filter size made specifically for your home's air conditioner or heater. We offer a variety of options using our pleated Accumulair filters which have an electrostatic charge to attract and remove air pollutants such as dust, pollen and mold spores. Our filters are up to 20x more efficient than those made by name brand manufacturers and we can produce air conditioning and furnace filters in almost any dimension to keep your home's air clean. 

Please use the following as a guide for ordering a custom replacement furnace filter or air conditioning filter.

• Check for a ready-made option: Before ordering a custom size filter, please be sure there is not a standard-made size by using the "Shop By Filter Size" drop-down menu to view all 1 inch filters, 2 inch filters, 4 inch filters and 6 inch filters.  We stock over 150 different size HVAC filters that are not just compatible but an improvement in quality over the usual brand name filters. Our standard sizes can replace filters from every major home filter brand including 3M Filtrete, Carrier filters, Honeywell filters and more. Choosing a ready-made filter will be less costly and require less time for you to receive it. If you can’t find what you are looking for continue with your custom furnace filter size order.
• Measure your filter size: Please accurately measure your home filter size in increments of 1/8 inch. Note there are filters that are actual size and there are filters that are cut smaller then the stated size that we have in-stock ie a filter may be labeled a 24x24 but actually measures 23.5x23.5 and we carry both.
• Choose your Filter Efficiency Rating: The most common efficiency scale used is MERV filter ratings which go from 1 to 16, with a higher rating meaning the filter will remove smaller particles from the air. There are also APR, MPR and FPR filter ratings scales created by various manufacturers. Be sure to use the efficiency rating that is recommended for your specific HVAC unit. Using a denser filter than is recommended will cause your furnace to work harder to push air through the filter and may lead to a costly repair.

• Delivery: You will find your order for a replacement furnace filter or air conditioning filter arriving within 2 to 3 weeks for delivery. Please note that custom furnace filter sizes are made to your specifications and once a custom filter order is placed, it cannot be returned for refund or credit.
