The air filter for your air conditioner, sometimes referred to as the blower filter to distinguish it from the air filtration systems used to improve indoor air quality, is an important component. It does the job of protecting the interior of the air conditioner from dust and dirt infiltration. The blower fan in the AC draws air through the return air ducts, and plenty of dust, lint, and other debris come with that air. The filter stops them so only the air gets through. The filter requires routine changes (every 1 to 3 months) so it won’t become too congested.
You can purchase different types of air filters at a range of prices. Is it better to go with the more expensive filters? Or are the lower-cost filters just as effective? We often hear these questions from our customers and we’d like to address them in this post.
