We recommend changing the RO Pre-Filters approximately every 6 – 12 months depending on use. If your average use is approx 2-3 GPD, change them after 12 months. If your use is 5-6 gallons a day, change them after 6 months. Adjust accordingly for higher or lower average use.

Change the post filter (polishing filter) every other time you change your pre-filters.

This set is for home drinking water R.O. Systems as well as the Aquarium Dual systems that are also used for producing drinking water (the polishing filter is not used in straight aquarium systems).
