Description  Replacement Filters  3 stage

The three  replacement filters included represent the prefiltration stages only for the standard residential reverse osmosis system. The pre-filtration stages help extend the service life of the reverse osmosis membrane.  Long term exposure to disinfectants can damage the  membrane and reduce the service life. It is important to replace the stages at the recommended intervals.  Microbiological flora can eventually grow in the cartridges and also form a biofilm.  Listed below are the recommended replacement schedules for the different stages:

Filter Stage Replacement Schedule
 5 micron spun-polypropylene sediment filter  6 months
 Granular activated carbon filter   6 months
 Activated Carbon Block Filter   6 months
 Reverse Osmosis membrane  2-3 years (check TDS)
 Post carbon in-line filter  12 months
