When it comes to choosing the best furnace filter rating, it's important to strike a balance between maximum oven efficiency and home comfort. The recommended MERV rating for oven filters ranges from 6 to 8, and it's a good rule of thumb to replace filters every two months. Homeowners with no air quality issues who are more concerned with protecting the oven do not need a high-efficiency filter. The FilterBuy MERV 8 pleated oven filter offers enough stopping power for pollen, allergens and mold spores, while providing great air circulation for the oven.
If you can't find Nordic Pure in your size, or if you prefer to buy and buy a new filter in a store right away, Honeywell's FPR 9 filters and Filtrete's MPR 1500 filters are similar and widely available in retail stores. Due to its durability, the FilterBuy 16x25x1 Pleated AC HVAC Oven Air Filter can last three times longer than other filters. The best oven filter should protect the active parts of your oven and trap dust, pet dander, and pollen to prevent these airborne contaminants from recirculating in your home. They work best in homes with allergy sufferers, smokers, or pets because they better filter contaminants.
Thicker filters are denser and block more dust and particles, but they can also make the oven work harder to draw in air. In actual use, with the air in your home constantly recirculating through the ducts and passing through the filters each time, the cumulative effect of the filters increases. A filter that removes the smallest particles provides the cleanest air, but may not provide enough airflow for the oven. 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. It is first and foremost a furnace air filter but can also be configured to function as an air filter when attached to a box fan. When selecting an oven filter rating for your system, it's important to consider all factors such as size options, MERV rating, durability and cost.
Doing so will ensure that you get the best possible filter for your needs.
