How Often Should You Change Your HVAC Filter?

A comfortable temperature inside your home helps you sleep better and enjoy time with your family without feeling miserable as outdoor temperatures climb. Regularly changing the air filter is a simple way to help your HVAC unit work as it should.

How often should you change your HVAC filter? Manufacturers recommend changing the filter every 30 days. Areas with seasons of extreme pollution, like wildfire smoke, may benefit from changing the filter more often.

What Does the HVAC Filter Do?

Every HVAC unit has an air filter that removes dust, mold spores, and other small particles from the air. They typically contain a pleated filter made of fiberglass with a frame of cardboard to hold it in place inside the HVAC unit. 

The Minimum Efficiency Reporting Value (MERV) on each type of filter lets you know how well it works at removing various pollutants from the air. Residential filters rated below MERV 17 are more than enough to filter out common household pollutants like tobacco smoke, dust mites, and pet dander. 

Filters with higher ratings are thorough enough for use in hospitals. While a filter of that strength isn’t necessary for most homes, individuals with respiratory problems or chronic illness could benefit from one.

Benefits of Replacing Your HVAC Filter

Still wondering how often you should change your HVAC filter? Often enough to keep your air clean.

Indoor air could be up to five times more polluted than outdoor air. That fact alone is reason enough for many homeowners to make replacing the filter a priority, but there are several other good reasons.

Eliminate Pet Odor

Pets can lose a ton of hair, which clogs air filters more quickly than you might realize. Pleated air filters that are covered in pet hair distribute pet odors throughout your home. Changing the filter regularly allows cleaner air to flow throughout, making your home smell cleaner.

Reduce Allergy Symptoms

If you or your family struggle with seasonal allergies, changing the filter can help a lot. Breathing filtered air can reduce seasonal allergy symptoms. It can also benefit people with conditions like asthma or cystic fibrosis.

Extend the Life of Your HVAC Unit

A well-maintained heating and cooling system can last well over a decade. An HVAC unit with a dirty filter will struggle to maintain the temperature inside your home. The more it struggles, the less efficient it becomes, until you end up wasting money on unnecessarily high energy bills.

A clean filter and regular maintenance will extend the life of your HVAC unit and help it to run efficiently.

The Consequences of a Dirty HVAC Filter

Let’s say you throw caution to the wind and decide not to change your HVAC filter. What could happen? Choosing to neglect your HVAC unit can cause expensive problems.

As dust and other pollutants build up, the filter can no longer remove them from the air supply. As your HVAC unit operates, the particles end up in your ductwork and vents, forming a thick layer of filth. Eventually, the pollution will restrict airflow and prevent your home from reaching a comfortable temperature, no matter how long your HVAC unit runs.

The strain on your HVAC unit can cause it to malfunction, and you will have to spend hundreds to replace it. Simply changing the air filter and scheduling an annual inspection can postpone the hassle of replacing your HVAC unit.
