Replacing the air filter in your HVAC system is one of the simplest, most effective ways to extend the life of your equipment, cut your energy bills, and improve the air quality inside your home. Unfortunately, this simple chore is also easily overlooked, with many homeowners leaving their filters in place for months at a time. Every home and HVAC system is different, so the guide below offers general advice for how often to put this maintenance task on your to-do list.

How Frequently Should You Change Your Air Filter?

Manufacturers offer a variety of designs and materials, some of which last longer than others. For instance, simple fiberglass filters are inexpensive, but they only trap the largest particles and clog up rather quickly. If you go for fiberglass filters, you will probably need to change it once a month, depending on the air quality in your home.

Pleated filters have more surface area, so they trap more allergens and dust than their fiberglass counterparts. Most homeowners will need to change or wash their pleated filters every 90 days. Some HVAC systems use advanced electrostatic filters, which generate a charge that attracts even the smallest particles in the air. Unlike the other types, these filters are permanent and should be thoroughly rinsed once per month.

Signs You Should Change Your Filters More Often

If anyone in your house is allergic to dust, pollen, or animal dander, you may need to change your filter more often to keep these contaminants out of the air. Families with especially furry pets may also want to check their filters frequently, as hair and fur can quickly clog even the most advanced HVAC filter.
