It’s one of those things that goes unseen, and therefore often unaddressed: HVAC air filters. The air filters in hour homes and businesses do the important job of removing particulates and dust from the air, purifying it in the process. But, how often should they be changed? Air filter subscription pros Tru Filtered Air demystify how to keep your indoor air quality up-to-spec.
Well, it comes down to a few factors, but a good rule of thumb is to change your air filters every 3 months or more frequently. 3 months assumes a healthy, well functioning air conditioning and heating system and a household without special needs of any kind.
