HVAC air filters are an essential part of your home’s heating and cooling system. They’re also one of the most ignored parts of the HVAC system. Air filters collect dust and pollen, preventing these particles from circulating through your home. Changing air filters regularly not only cuts down on the dust in the home, but clean filters also contribute to better indoor air quality.
In this post, you’ll learn the benefits of changing air filters on schedule and why indoor air quality companies insist a clean filter makes it easier to breathe in your home.
Benefit #1 – Better Heating and Cooling
Have you noticed that your HVAC unit runs more but produces fewer results? A dirty air filter makes it harder for units to do their jobs well. The blower fan in the HVAC unit must work harder to push air through the system. If you notice warm air coming from the vents when it should be cool and vice versa, check your air conditioners filter. Replace it if it’s dirty, and you should notice a difference right away.
Benefit #2 – Longer HVAC Lifespan
You want to keep your HVAC system running well for as long as possible. Fortunately, regular filter changes can keep your heating and cooling unit running with minimal problems for decades. A well-maintained system can last up to 25 years, and filter changes play a huge part in your HVAC’s longevity.
Benefit #3 – You’ll Breathe Easier
Indoor air quality testing reveals a lot about your home. If you’ve ever had indoor air quality service done, it probably surprised you to learn how many airborne pollutants were in your house. Clogged air filters are a top source for poor indoor air quality results. When an air filter becomes clogged, it can’t filter incoming pollutants and can even distribute trapped pollutants back out into the house through the vent system. Changing air filters can reduce respiratory symptoms, lower risks of an asthma attack, and keep your household healthier.
How Often Do Air Filters Need to Be Changed?
Most air filters need changing every 30-90 days. The exact interval depends on the air filter you use and the amount of pollutants in the home. Cheap air filters work fine for most units, but they require changing every 30 days. If you want more time in between air filter changes, pay close attention to the Minimum Efficiency Reporting Value (MERV) rating. A higher MERV rating means the filter will pick up finer particles and clean the air better. You might pay more for a higher MERV rating, but you’ll have better indoor air quality, and your HVAC system will run more efficiently.
