Do All Furnaces Need Different Size Filters?

When it comes to furnaces, there are a variety of sizes and types available. However, most of them use a common furnace filter size. Before you replace your filter, it is important to know what size and type you need. Depending on the brand of oven you have, you may need an electrostatic or media filter of a specific size.

To determine the size and type of filter you need, take a look at the old oven filter. For instance, one of the most popular oven filter sizes is 20 x 25 x 1 inch in nominal size. The actual size of the oven filter measures 19.5 x 24.25 x 0.75 inches. Nominal sizes are used to simplify furnace filter sizes and both sizes are usually printed on the sides of the oven filter. Since air filters and ovens are essentially the same, there are hundreds of different sizes of oven filters available.

Filter King

offers a wide selection of filter sizes that can be used in various home systems, including the oven.

To find out what size your oven requires, simply remove the existing oven filter and check the label. If you have already discarded the old oven filter, refer to the user's manual for this information. As long as you know how to read it and where to find it, replacing an oven filter should be a breeze. If your current furnace only allows furnace filters with a depth of one inch, HVAC contractors can modify the furnace to accommodate larger sizes. To get the nominal filter size, round up to the nearest inch. Filter King also provides an air filter size chart that can help you quickly choose the right size for your home system.

By learning more about air conditioning and heating filter sizes, you can ensure that you find the perfect size for your home. It is important to always use the right furnace filter sizes in order to protect your home comfort, indoor air quality, and reduce HVAC costs. Please note that the sizes of the air conditioner and oven filters must be smaller than the measurements of the filter compartment.
