Second Nature offers the highest quality filters available. All last up to 90 days and are high-efficiency (low resistance) pleated filters manufactured in the U.S.A.! They’re the same quality as the top-end, high-efficiency filters you can find at your local hardware store—but we send them right to your door for a price that is comparable or lower. If you need help choosing the best filter type for your home, please contact us. We’re always glad to help.
