Reverse Osmosis Filter Change Frequency
I have a reverse osmosis system GXRM10G. Family of 2. How often should I change the postfilter sump and prefilter sump and should I change the RO cartridge at the same time?
Most Revers Osmosis Filter Systems require pre and post filter changes at 6 month intervals to maintain peak performance. The membrane should be changed every 2 years or if you notice a significant drop in water passing through the reverse osmosis system. In your case the GXRM10G uses the FX12P pre and post filters which should be changed every 6 months and the fx12m membrane which should be changed every 2 years. The O-rings should be changed every other filter change on the pre and post filters and every change on the membrane.
