If you are concerned about indoor air quality, the best furnace filter for your home is a disposable electrostatic filter. These filters contain self-charging electrostatic cotton or paper fibers that attract and trap small particles, making them an ideal choice for homes with children, pets, or smokers. With a MERV rating of 10, these options are affordable in standard sizes, but custom sizes can be expensive if replaced regularly over several years. HEPA filters are dense and can reduce the airflow entering the oven, so they are generally used only in commercial ovens or hospitals. With a MERV rating of 16-20, they block the highest level of particles in the air and provide better air quality, but they are not suitable for most residential ovens.
Oven filters come in dozens of sizes, with the three most common being 16 by 20 inches, 20 by 25 inches and 16 by 25 inches. The thickness of the filter varies from one to five inches, and in general, the thicker the filter, the more particle blocking capacity it will have. Before choosing a filter, you will need to consult the owner's manual or operating manual as not all ovens accept a thicker product. As the filter becomes thicker, the oven must work harder to draw air through it, reducing its efficiency and service life. The Filtrete AC oven air filter is presented as our best overall oven replacement filter. Its high-efficiency MERV-12 rating makes it an excellent choice for homeowners who want to trap as much debris as possible in the air.
Changing oven filters is a breeze with this option as it comes in more than a dozen sizes. The Nordic Pure MERV 12 pleated air conditioning oven filters block a high level of dust and other airborne contaminants that could otherwise end up in the oven or be recirculated throughout the home. These disposable pleated filters are hypoallergenic and feature electrostatic fibers that attract contaminants and resist mold and mildew growth. These AC oven filters are one inch thick and come in a variety of sizes. Because these filters offer a high MERV rating of 12, they can clog more quickly than filters with lower scores. Depending on how often the oven works, you may need to replace them more often than every three months.

One of the best choices overall is the Filtrete oven filter with its disposable electrostatic design, multiple size options, MERV rating of 12, and 3-in-1 technology to trap lint, dust, pet dander, soot, pollen and mold. The preferred type of oven filters are pleated and electrostatic disposables because of their ability to filter lint, dust, pet dander, soot, pollen, and mold spores while many picks are unable to filter out smoke and bacteria. Most options come in various sizes and thicknesses to be compatible with your oven while having MERV ratings ranging from 8 to 12 without impeding airflow. As for special features, arrows are included in the frame to direct placement and airflow while some offer odor control or even Bluetooth capability for added convenience. According to a CNN article HEPA filters with MERV ratings of 17 to 20 are best at reducing the spread of viruses but most household ovens cannot draw air through a dense HEPA filter. Many oven filters need to be changed every 2-3 months so many options come with 4-6 filters per purchase while some may last 9 to 12 months before requiring a replacement.
