How To Install An Air Filter In a Furnace

A furnace’s air filter plays a key role in preventing you from breathing in dust, pollen, and other pollutants. Therefore, it is important that you understand which type of air filter your furnace needs and how to install it correctly.

What Type of Filter Does My Furnace Need?

An air filter will come with either a cardboard or plastic border, and it will vary in thickness from 1 to 5 inches. If the filter has a plastic border, it can likely be reused after you clean it. Typically, a furnace is built to take filters that are 1 to 2 inches thick on the sides. Generally speaking, the thicker the filter, the better it does at removing debris from the air. You can consult the owner’s manual to determine the best choice for your product.

Put the Filter in the Right Way

Once you have a filter that is right for your furnace, the next step is to install it. There should be an arrow that tells you which way it is supposed to be installed. It may be a good idea to trace that mark in permanent ink so that you will always know which direction is the right one. It is also a good idea to write the date it was installed on the filter cover.

Filters Should Be Replaced Every Few Months

Ideally, a furnace air filter will be replaced once per quarter for best results. The folks at Black Lion Heating & Air Conditioning in Seattle can help you to take care of this task or any others that can help keep your furnace in good condition.
