One of the most important furnace and air conditioning maintenance jobs a homeowner can perform is to regularly inspect and replace their HVAC air filter. Filters help collect dust and allergens from circulating throughout the home and protect the delicate interior of your heating and cooling equipment.  

Did You Know? Your furnace and air conditioner share the same filter. Since both units use the same air handler, they also use the same filter. Depending on your system, the filter could be located in the return air duct or near the blower (which is usually found in front of the furnace).

Replacing HVAC air filters is an easy task, but many homeowners get confused about which type of filter they should be using. There are many different options and brands available, but there are three 3 main types:

1. Standard Fiberglass Filters
   These are the most common type of filter available on the market and most likely the one many homeowners are familiar with. They are the least expensive option but only last about 30 days. The woven fiberglass strands are able to trap large airborne particles but don’t do much to trap allergens and other pollutants from circulating throughout your home.

2. Pleated Filters
   The next step up from the standard air filter is pleated. Usually made from synthetic fiber, the pleats help to filter out smaller particles—protecting your family from dust, pollen, dander and mould. While these type of filters cost a bit more, they last twice as long—usually needing replacement every 60 days.

3. Media Filters
   For people that suffer from allergies, media filters are often the best option. These HVAC air filters are bigger than the other options, often times measuring at least 5 inches, and usually last six months before they need to be replaced.

Always refer to your user manual to ensure you’re using the right type of HVAC filter for your system and then choose the filter that best suits your family’s needs.
