Currently, the most commonly sized oven filters are 10x20. But if your system needs custom-sized air filters, keep in mind 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. Oven filters come in a variety of sizes, with 16 by 20 inches, 20 by 25 inches and 16 by 25 inches being the three most popular. The thickness of the filter can range from one to five inches, and generally speaking, the thicker the filter, the more effective it will be at blocking particles.
Before selecting a filter, it's important to consult the instruction manual or the manufacturer's instructions, as not all ovens can handle thicker products. As the filter thickens, it requires more effort from the oven to extract air through it, which can reduce its efficiency and lifespan. For example, one of the most popular oven filter sizes has a nominal size of 20 x 25 x 1 inch. The actual size of this oven filter measures 19.5 x 24.25 x 0.75 inches.
It's also important to note that placing the filter backwards may cause it to collapse and allow air to flow around it instead of through it. When shopping for an oven filter, make sure to check the actual size (the dimensions measured by the filter) to ensure you have the correct model number. An inexpensive oven filter like this Rheem option is an affordable way to keep up with this important home maintenance task. These filters are made with media (usually cotton or paper) that has been permanently charged to attract dust and other particles. Although it may seem like a small detail, choosing the right oven filter can save money and improve air quality.
If your HVAC system uses a whole house filter (located close to your central furnace or air conditioning unit), you'll likely find the model number instead of the dimensions. Homeowners should also keep in mind that there are other factors that determine how often air filters should be replaced. For standard size one-inch air filters, you can buy them at Lowes, Home Depot, Walmart, or online and usually find several standard sizes quite easily. The most basic disposable oven filters are made of fiberglass and only capture larger dust and dirt particles. We researched the most sought after oven filters in their respective categories and found that the best options available are compatible with many brands of HVAC systems and ovens, filter out as many annoying particles and contaminants as possible, have a long lifespan and have a high MERV rating. Most people won't be able to find the size air filter they need at their local home improvement store.
On the other hand, if you're only concerned about capturing large particles to prolong the longevity of your air conditioning system, then an affordable Rheem indoor air filter is an economical option. The specific maintenance required varies by type and according to manufacturer instructions, but normally only low-pressure water and perhaps a mild cleaner are needed to remove contaminants from the filter. Many oven filters need to be changed every 2 to 3 months, so many options come with 4 to 6 filters per purchase.
