My Filters Don’t Need to Be Changed That Often – FALSE! The experts are correct on this one, you need to change your filter every month. If you typically buy air filters with higher MERV Ratings such as MERV 11 or 13, then it is recommended that your filter changes every THREE months. However, if you have respiratory ailments such as asthma or allergies, monthly air filter changes still apply. This rule is especially strict on smokers and those with indoor pets, regardless of MERV rating.
