The Best 20x25x4 Filter for Your Oven

When it comes to choosing the right oven filter, there are a few things to consider. Disposable electrostatic filters are a great option for homes with children, pets or smokers, as they contain automatically charged electrostatic cotton or paper fibers that attract and trap small particles. With a MERV rating of 10, these filters are affordable in standard sizes and can be replaced regularly over several years. However, HEPA filters are too dense for most residential ovens, as they can reduce air flow to the oven and are generally used only in commercial ovens or in hospital settings. The Filtrete AC oven air filter is presented as our best general replacement filter for ovens, as it has a high-efficiency MERV-12 rating and is available in more than a dozen sizes.

Change oven filters in the blink of an eye with Nordic Pure MERV 12 pleated air conditioning filters, which block a high level of dust and other air contaminants that could otherwise end up in the oven or recirculating throughout the house. These disposable pleated filters are hypoallergenic and feature electrostatic fibers that attract contaminants and resist mold and mildew growth. For those looking for an even higher level of particle blocking capacity, the AirX ALLERGY MERV 11 pleated air filter is designed with additional density to trap airborne allergens that may trigger allergy symptoms. It's also good for blocking smoke and odors. The MERV 11 filter is dense and helps prevent allergens from recirculating through your home's ducts. If you have pets, check out the Aerostar Allergen & Pet Dander MERV 11 air filter, which blocks large amounts of particles in the air, such as pet hair and dander.

This highly efficient electrostatic filter attracts particles and traps them in place. This disposable pleated filter is available in a variety of 1- and 2-inch thick sizes to fit a wide range of ovens. Affordable and durable, the Honeywell Home MicroDefense air conditioner filter has a MERV rating of 8 and comes with 4 filters with V-shaped pleats for a larger surface area and greater airflow. This 4-inch thick disposable filter features deep folds and electrostatically charged fibers that capture and retain a large amount of particles in their cracks. The filter is only available in 2 sizes, the dimensions of 16 inches by 25 inches by 4 inches and 20 inches by 20 inches by 1 inch. For those looking for a longer-lasting filter, Honeywell Home's MicroDefense air conditioner filter lasts up to 12 months before it needs to be replaced.

In addition, this filter can help control odors. With so many options available, finding the right oven filter can be difficult. 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 spores. While many tines aren't able to filter smoke and bacteria, most of these options come in various sizes and thicknesses to make them compatible with your oven. As for MERV ratings, most of the above products range from 8 to 12 without impeding air flow. The selections selected from the list above may last longer than 2 to 3 months at a time, but for added convenience, some will last longer than 12 months or come with several filters.

As for the special features, arrows are included in the frame to direct the location and airflow, odor control, HEPA filters and even the Bluetooth function for greater convenience. According to a CNN article, HEPA filters with a MERV rating of 17 to 20 are the best at reducing the spread of viruses, but most household ovens cannot suck air through a dense HEPA filter. Many oven filters need to be changed every 2 to 3 months, so many options come with 4 to 6 filters per purchase.
