The effective life of your air condition filter depends on both the inside and outside conditions in which you live. It is important to regularly change your air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 30 days to maintain maximum efficiency and economy.
