How Frequently Should I Change My Home Air Filters?

Taking good care of your HVAC system is essential to increasing its longevity and efficiency. One of the crucial steps you can take to guarantee this is changing your air filters regularly. This way, you can keep everything working properly and reduce your energy consumption.

Unfortunately, many homeowners forgo this simple task for months at a time, resulting in future maintenance issues and higher energy bills. Despite their durability, air filters don’t last forever. You need to keep track of when they were installed to know when it’s time for a replacement.

However, how often you replace your air filters varies depending on numerous factors, including the number of pets, air filter model, and household size. To help you get started, here are some general rules and recommendations on changing your air filters.

How Often To Change Home Filters

Generally, experts recommend changing your air filters every 30 to 60 days. If you’re using less expensive fiberglass filters, change them after 30 days and for high-end pleated filters, replace them after 90 days.

Other factors to consider when changing your home filters include:

1. Does Anyone In Your Home Have Allergies Or Asthma?

If your partner or child suffers from allergies and asthma, keeping your indoor air quality clean is vital to maintaining their long-term health. To achieve this, change your filters every six weeks to eliminate contaminants in the air that might trigger allergies.

2. Do You Have Pets?

If you’re a pet owner, you might want to change your air filter every two months. Pet odor and dander can quickly build up over time, affecting your indoor air quality. So, change your air filters more frequently if you have pets, especially during shedding season.

3. Do You Have Younger Children?

Younger children need fresh and clean air at all times to prevent allergies and other health issues. Therefore, replace your air filter every 2 to 3 months to keep your indoor air quality at its best.

4. Seasonal Changes 

During flu and allergy seasons, it’s wise to replace your air filters with high-efficiency models to eliminate contaminants and pollutants in the air. 

5. Size Of Your Home

Typically, smaller homes require fewer filter changes as the HVAC system pumps less air for the same amount of temperature change. However, if your HVAC appliance is small, you’ll need to change the filter more often because its filters are small, and they clog quickly than large filters.

Bottom Line

Ultimately, remember the longer your filters are in place, the more dirt, dust, and allergens they trap, clogging your filters and decreasing your HVAC efficiency. So, you’ll want to replace your filters more often than recommended to keep a clean and allergen-free environment.

To be on the safe side, check your filters at least once a month for airborne particles and pollutants. If there’s build-up, it’s time to replace them with new air filters. This way, you can keep your unit running at maximum efficiency and your indoor air quality clean.
