Air filters are critical for your HVAC system to keep things like allergens and dust/dirt particles from blowing around your home. The filters work, but they need to be replaced when they get too dirty. And a dirty filter can reduce airflow, which forces your HVAC system to work extra hard. Since filters need to be replaced on a regular basis and can be easily forgotten, consider signing up for a subscription service to have filters automatically sent to you when you need to replace your old ones.
