The Importance of Changing Your Air Filter Regularly

The Importance of Changing Your Air Filter Regularly

Having a clean air filter for your HVAC system is crucial. It not only prevents your unit from working extra hard and breaking down, but it also improves the air quality in your home. Changing air filters might seem like a small task among DIY home improvements, but it’s a quick and painless job that takes less than an hour. Surprisingly, many homeowners aren’t aware of how often their air filters should be replaced, which can lead to damage over time. Keep reading to find out when and how you should change your air filter.


Why You Should Care About Changing Your Filter

Air filters play a vital role in capturing pet hair, dust, and other particles, ensuring that the air circulating in your home is fresh and clean. As time goes on, these filters accumulate so much dirt and debris that they can hinder proper airflow to your HVAC unit, leading to:


Higher energy bills—A clogged HVAC filter forces your system to work harder to cool or heat your home, resulting in longer operation times and increased energy consumption.

Health issues—When a filter isn’t functioning correctly, allergens and dust can spread throughout your home, triggering allergies and respiratory problems.

System breakdown—Straining your HVAC unit with a clogged filter can lead to breakdowns, potentially resulting in costly repairs or replacements.

How to Replace Your Air Filter

Ideally, you should replace your air filter every three months. However, there are specific factors to consider when determining the right replacement schedule:


Filter type—Different air filters vary in effectiveness. Cheaper fiberglass filters need monthly replacements, while high-quality pleated filters can last up to 90 days, effectively trapping particles.

Pets—If you have furry companions, you should change your filters every two months to maintain clean air.

Allergies—For allergy sufferers, even a small amount of airborne debris can trigger reactions. To ensure clean air, replace your filters roughly every 50 days.

Children—To maintain good indoor air quality with kids around, swap out filters every two months.

Home usage—If your HVAC system operates daily, you’ll need more frequent filter changes compared to a vacation home where the system runs less often. For occasional usage, replace filters every six to 12 months.

Although these factors influence the frequency of replacements, it’s a good idea to visually inspect your filter monthly for excess buildup. If your filter is covered in dust and debris, even if it hasn’t reached its recommended lifespan, it’s time for a change.


How to Perform a Filter Replacement

Here’s a step-by-step guide for replacing your air filter when it’s due:


Get the right filter size—Check the size of your old filter, which is usually printed on its side. If you can’t find it, use a measuring tape to determine its dimensions.

Turn off your unit—Either switch off your thermostat or shut down the system at the circuit breaker.

Locate the filter—Your air filter is either in a return duct or an air handler in your attic, basement, or utility closet.

Remove the cover or grille—Access the filter by opening the panel of the air handler (you might need a screwdriver) or flipping the latches on the grille.

Replace the old filter—Take out the old filter and observe how it was placed. Insert the new filter, ensuring that the airflow arrows are pointing into the unit.

Put the cover back and turn on the system—After replacing the filter, turn the system back on to confirm proper placement and smooth operation.


By following these steps and maintaining a regular filter replacement schedule, you can help ensure the efficiency and longevity of your HVAC system while enjoying better air quality in your home.
