Choosing and Changing Your Furnace Filter

HVAC contractors will tell you that keeping up with changing your furnace filter is important. But what type of filter is best for your system and how often should it be changed? Here are some guidelines for making the right choices and prolonging the life of your HVAC system:

Types of Furnace Filters – How to Choose

There are many types of HVAC filters, each boasting different advantages, and drawbacks. Some of the most common include:

  • Fiberglass and Synthetic Filters – These are some of the least expensive filters on the market and are disposable, making them a go-to choice for many households. They also allow maximum airflow, reducing energy costs. However, these filters do little to contain harmful particulate matter and may not be effective enough for your family’s need.

  • Pleated Filters – Pleated filters are a sort of happy medium between low-efficiency and expensive high-efficiency filters. They provide far better protection from smaller particulate matter than fiberglass or synthetic filters without hindering your home’s airflow – or costing you a mortgage payment to replace!

  • HEPA Filters – Short for high-efficiency particulate air, HEPA filters are some of the top-performing in the industry. They provide a 99% or higher filtration of particles as small as 0.3 microns. However, they are more expensive than other options given their high performance and can also reduce the airflow efficiency in your home, racking up additional energy costs.

Ultimately, which filter you choose will depend on which type your system was designed to work with. If upgrading or changing the filter is an option, ask an industry professional before trying a new type.

How Often Should You Change Your Filter?

Air filters in your HVAC system should typically be changed every 1-3 months, depending on a variety of factors. Changing them more frequently may cost more upfront but will also ensure better efficiency of the filter and better quality of your home’s air.
