When it comes to ovens and air conditioners, the most common filter sizes are 10 X 20 X 1", 14 X 20 X 1", 16 X 24 X 1", 18 X 30 X 1" and 20 x 1, 16 x 25 x 1, 20 x 25 x 1, 20 x 25 x 4.Understanding the numbers behind these measurements can be tricky, but it's important to know the size of your filter in order to get the best performance from your HVAC system. The size of an oven filter is typically shown in bold type on the filter frame. This is known as the nominal size, which may differ from its actual size. To get the nominal size, round up to the nearest inch.
For example, if your filter measures 15 3/4" by 23 3/4", you would round up to 16" by 24". When installing a filter, it's important to leave a little wiggle room in the slot of the HVAC unit. This will make it easier to slide the filter in and out without bending or breaking it. If you have to jam the air filter to install it, you should try a different brand or a custom-sized air filter with a slightly smaller actual size.
The primary purpose of air filters is to protect your HVAC equipment from damage caused by dust and dirt accumulation on the coils. However, they also help improve air quality in your home, which is one of the top health issues listed by the EPA, CDC and American Lung Association. Colorfil filters are designed to eliminate chemicals and odors at a molecular level that normal air filters can't. They were originally created for NASA and are now available for purchase online or at specialty stores.
When shopping for an oven filter, make sure you know the nominal size of your filter so you can find one that fits properly. Most people won't be able to find the size they need at their local home improvement store, so they may need to shop online or at specialty stores.
