Gave you ever opened your air filter grate, and brown dirt and dust came floating down? When was the last time you changed the filter, anyway? Choosing the correct filter and maintaining your air system can be critical to breathing clean air and preventing issues later on.  We have several tips to help you choose the right air filters for your home, so you can improve indoor air quality.

  1. Upgrade from Flimsy to Firm. We all know the most common, and often cheap, flimsy fiberglass air filters that may or may not actually be filtering dirt and dust particles. In fact, they don’t filter much out at all! Purchasing a little bit more expensive filter will do a better job of catching those nasty pollutants and helping to clear the air.
  2. Buy Pleated Filters. Pleated air filters dramatically increase the amount of pollutants that are trapped from the air in your home. You may notice an immediate difference when using this type of filter versus a flat filter. Pleated filters may cost a little bit more, but it will be worth it so you aren’t breathing in dust and air pollutants.
  3. Consider High-Efficiency Filters. We recommend high-efficiency filters because they trap a significant portion of the air pollutants in your home. They trap the smallest air particles, and especially if you have allergies or suffer from respiratory issues, these filters will support your overall health.
  4. Read Air Filter Ratings. Although there is no universal system for air filter ratings, comparing multiple ratings may help you choose the right filter. Check for initial and sustained efficiency, dust holding capacity, and MERV (Minimum Efficiency Report Value).
  5. Determine the Best MERV Rating. Most air filter packages will include a MERV rating and generally are listed from 1 to 16. A general rule of thumb is ratings below 5 are low-efficiency and should be avoided. Ratings between 8 and 12 are great mid-range choices, and ratings above 12 would be considered high-efficiency.
