Are Furnace Filters and Air Filters the Same?

When it comes to air conditioning and heating, many people mistakenly think that the filters are different. However, the truth is that the same filter is used for both your oven and air conditioning system. While both filters serve the same purpose of cleaning the air in your home, there are some differences in terms of filter location, service life, filtration level, and cost. If you need to replace your filter, most large retail and home improvement stores will carry oven filters. A clogged or dirty oven filter can cause performance issues with your oven, as air cannot pass through the channels to the heating elements.

The differences between oven filters and air conditioning filters become more apparent in older homes or homes with special heating and cooling needs (such as those in New England). Overheating can also occur, which can burn out the oven's internal operating system or damage sensors that measure air temperature. If you're not sure when you last changed your air filter, it's time to replace it. Reusable air filters are also available and are more environmentally friendly. If you need a replacement air or heating filter, Filterbuy offers delivery right to your door.

The most common location for an air filter is in the return air duct or blower compartment, as this allows the filter to clean the air before it reaches the unit. Heating and cooling systems use an air filter to clean incoming air before it is conditioned and distributed throughout the home. If you're experiencing any of these problems at once, it could be time to change both the central air system and oven filters. In most cases, the central air system uses two separate filters to properly filter out unwanted particles, allergens, bacteria, and more. If you find yourself reaching for a nasal spray and lubricating eye drops when your oven or central air system turns on, it's likely time to change your filters. Overheating can become common when a clogged filter prevents air from passing through.

This puts extra strain on the internal components of the system and can lead to a system failure. To avoid this problem, make sure you regularly check and replace your furnace and air filters.
