During normal operation your filters become dirty and need to be replaced about once a month. Special situations such as exceptionally dusty surroundings or lengthened runtimes may require you to change them more often. Always remember to replace them with the same kind and size, unless instructed otherwise by an HVAC professional.
If you’re tired of constantly buying new filters to replace the ones you’re throwing away, ask us about our lifetime filters like the Permatron media filter or Trane’s Perfect Fit electronic air cleaner. Not only will you eliminate the need to buy replacement filters, but your home can be healthier for you and your family as well since these filters remove far more of the airborne pollutants we breathe in on a daily basis.
