What is the Best Air Filter for Home Furnace?

When it comes to choosing the best air filter for your home furnace, there are a few factors to consider. Filtrete 20x25x1 AC Oven Air Filter and Filtrete 10x20x1 AC Oven Air Filter are two of the most popular options. These disposable electrostatic filters contain self-charging 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 are a good solution for homes with children, pets, or smokers.

Oven filters come in dozens of sizes, with the three most common sizes 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.
