All About Your Air Filter

Written by: Metro Air

Do you know how clean the air you breathe is? Air filters help provide clean air, so your lungs and body stay healthy.

What role does an air filter play?
Air filters are a critical component of your home’s heating and cooling system. They take outside air, and as it travels through the machine, they help filter out pollutants, bacteria, and other harmful toxins that could make their way into the air you breathe. The filter essentially traps these potentially damaging particles.

Air filter essential tips:
Your filter should be cleaned or replaced every other month. If you have multiple pets in the home or your area has a high level of pollution, smog, or smoke, you should clean or replace them monthly. In addition, look at how thick your filters are. If they are one inch, they will need to be changed more often than those that are thicker (up to 4 inches). The thicker the filter is, the more layers it has for collecting debris, dirt, and other harmful particles. We do not recommend using 3m filtrate filters, as they can restrict airflow and cause problems with your system. We recommend using 4” filters.

What is a MERV rating?
The Minimum Efficiency Reporting Value (MERV) rating calculates how much matter passes through your air filter. The ratings are from 1 to 16. The higher the number, the better the filter.

See below or visit the EPA website here for more information.

  • 1 to 4 MERV rating: catches particles that are larger than 10 micrometers. These include bugs dust mites, and other household debris
  • 5 to 8 MERV rating: captures particles bigger than 3 micrometers, including mold and pet dander
  • 9 to 12 MERV rating: catches particles bigger than 1 micrometer, including dust and other common household contaminants
  • 13 to 16 MERV rating: captures particles greater than 0.3 micrometers such as bacteria or smoke/pollution
