Can't find furnace air filter?

If you can't find the filter next to the return air duct, look for it behind a return air grille on the wall. Alternatively, you can find an air grille in the ceiling with the filter hidden behind. The filter looks like a mesh screen enclosed in a thin box. Perhaps yours is a vertical HVAC unit with air that moves upwards.

The oven filter will be on the bottom door and this is where the blower is. To get to the filter, open the upper and lower doors. Finally, if the unit is a vertical HVAC unit and the air is moving downward, the air cleaner will be on the upper door. The blower is also located here and this type of oven or air conditioning unit may also require two filters.

What is the location of the oven air filter in my HVAC system? It is usually located behind a metal compartment door near the floor or side of the oven. If you don't see a filter yet, you may need to remove the oven lid to access the filter. But before removing the cover, it's time to look carefully around the house, as the filter may be in a ceiling or wall ventilation grille. A clean oven filter ensures that the unit can operate efficiently by allowing warm air to pass unhindered through the ventilation grilles.

The short answer to this question is yes, all ovens have a filter to work properly. The location of the oven filter will vary depending on which oven you have, but there are a few basics that everyone should know. If there are air conditioning filters on the return grilles, then there shouldn't be a filter in the oven, even if there sometimes is one. Examples are a clogged condensate drain pipe, the drain pan is damaged or rusted, the condensate pump is broken, the air filter is not clean, or the coolant is low.

The oven filter should be changed every 90 days, especially when using the oven and air conditioner. The oven filter is located in the large metal (sometimes plastic) compartment of the oven next to the blower, near the bottom of the door or on the side of the door. The photo on the left shows a residential oil oven with central air conditioning and an in-line humidifier. Most air handlers will also have a central return air duct, which has built-in filter grilles to accommodate a filter.

In addition, the filter cleans the air leaving the oven before it enters the home, eliminating pollen, allergens and dust mites. As indoor air enters the ducts of your HVAC system, a filter works to remove particles and debris before they come into contact with sensitive oven components. Let's take a look at why you need to know where the oven filter is located, background information, location, how it works, how to choose one and replace, maintenance, HVAC lifespan, and when to call a professional.
