Turn off the power to the oven so that it doesn't work halfway through the change. Pull the old filter out of the slot. If the filter is held in place by clips, unfasten the clips and remove the old filter. Insert the new filter into the slot where the old filter was; if clips are used, place the filter in the clips and reattach them.
Pay attention to the airflow arrow mark on the filter. You should point toward the oven or fan when you install the new filter. More expensive filters serve the same function, plus they can improve the air quality in your home by trapping bacteria, pollen, and mold and mold spores. You may find that the size of your air filter is rare, in which case you'll need to place a custom order at a specialized filter store and ship it home.
Some ovens use a box filter 4 inches or more thick that contains several layers of filter material. Take three measurements: the depth of the return air duct, the height and width of the space in which the air cleaner slides. Varieties such as the FilterBuy MERV 8 air filters (available on Amazon) are a little more expensive but will last from four months to a year. With a central forced air heating and cooling system, the heat pump, oven, or air conditioning filters remove dust and allergens from the air before heating or cooling the air and returning it to your rooms.
When air filters are clogged, the HVAC system works harder to produce the same amount of air for your home. Proper maintenance of oven or air conditioner filters is an important way to keep heating and cooling as affordable as possible. Replacing the air filter is important because it can extend oven life, reduce energy bills, and improve indoor air quality. Typically, you should change a basic fiberglass oven filter every one to two months and paper oven filters every four months or a year.
The filter itself is a 1-inch thick cardboard or plastic frame the same height and width as the air duct, which holds the filter material flat or pleated. Options such as 6-stage electrostatic air filters (available on Amazon) can be rinsed with a garden hose as needed and reused for several years if properly maintained. Since most of the air in your home circulates through the HVAC system, oven filters are your first line of defense against airborne dust and allergens. When you can replace the air filters in your home, you'll move toward cleaner air in every room.
The air cleaner is located somewhere inside, either inside the air duct system or inside the indoor HVAC unit itself.
