Question: 

How often should I replace my air filter?

Answer:

Most standard 1” (MERV 8) pleated air filters are good for 60-90 days. If you use a higher efficiency filter (MERV 11 or greater) you may need to change it more often as they can cause an air restriction due to the larger surface area. Filters 4” wide or larger are typically good for 6 months. It is always good practice to check your filter every month. A restricted air filter can cause many operational issues.
