Currently, the most popular size oven filters are 10x20. But if your system requires custom-sized air filters, you should know that we offer custom sizes ranging from 8 x 24 x 1 to 25 x 30 x 1.Let's take a look at the most common oven filter sizes and where to buy them. To the right of the filter, you will also find the actual filter size, which are the exact measurements of the filter dimensions by length, width, and depth. If your HVAC system uses a whole-house filter (which is usually close to your central oven or air conditioning unit), you will likely find the model number instead of the dimensions.
However, it must fit snugly into the air cleaner compartment with a little space around the edges. So if you need to find household air filter sizes, HVAC filter sizes, oven filter sizes, AC filter sizes or air conditioner filter sizes, you are looking for the same thing. If the return grille is in the ceiling, it is recommended to use a filter that has a slightly larger actual size, so that it does not fall on you when you open the vent. Not only does this prevent you from making frequent purchases, but it also allows you to change filters more often.If there is no size on your current AC filter, you can measure the length, width and depth of the filter and compare it to the oven filter size table (nominal size).
Filters are measured by nominal size, which is a rounded number that varies by brand, so many filters have the part number of each brand they are compatible with. Cheaper fiberglass flat filters may require a change every 30 days and can even be labeled as a 30-day filter. The image of this 12 x 12 x 1 inch air filter has the nominal size, which is what air filters are usually sold for. You can proactively clean the air and surfaces in your home by adding an air purifier in the duct that creates supercharged particles.
Each mark may have actual sizes that are different from the nominal size (the size on the label is sometimes a rounded size) that appears on the filter label. In addition, if there is any resistance to airflow caused by using a filter that is not the correct size, it can cause unnecessary stress on the HVAC unit itself, which could damage system equipment and increase energy bills.
