 ## Using high-quality, properly fitting air filters, and replacing them often, is one of the cheapest and easiest things you can do to extend the life of your HVAC system.

High-quality air filters cost more, but they can easily pay for themselves by improving indoor air quality (IAQ), reducing the likelihood of expensive repairs, and improving your system’s efficiency and performance. In fact, it’s estimated that a clean, high-quality air filter can reduce your air conditioner’s energy consumption by as much as 16 percent!

The basic function of any air filter is to trap dust, pollen, mold spores, and other airborne particles in its fibers. As filters age and deteriorate, they lose the ability to trap new particles, and they can release those same fibers and other debris into your system.

Higher-quality air filters will trap more particles, this is particularly important if you suffer from allergies or a respiratory condition like asthma or COPD, but a higher MERV rating is no substitute for a properly fitting filter that is changed regularly, and you can overdo it. A higher MERV rating means less airflow, which can damage your HVAC system.

When any air filter becomes clogged, air will bypass the filter
