Derek Cole says check your HVAC filter every 30 days, but checking isn't the same as replacing. How often you actually swap it depends on how many people live there, pets, outdoor air exposure, and other household factors. Monthly inspection tells you when it's actually dirty enough to need changing.
You've heard others say, you've heard me say before, check your filter every 30 days. And now, that doesn't mean you have to change it every 30 days, but it should be checked every 30 days. How often should I change my filter? It depends on your home. How many people's in the home? How often you go outside in the home? How many pets do you have in the home? What are the living conditions in the home? All that plays into how dirty the filter will get. So how often do you need to change it? That's going to depend on your specific situation, but a great rule of thumb is check your filter every 30 days to see if it needs to be changed. You will see it getting dirtier, which is what you want because the filter is there to get dirty.
