the main stage in this system is the RO membrane; all the other replacement filters serve and protect that membrane. If the pre-filters fail to work due to poor quality, your RO membrane will not give you a 99.9% reduction rate.
 
It includes two filters and a membrane that must be replaced periodically.
The different filters represent the different stages that the water goes through while being purified.
 
Generally - Pre-Filters and post-Filters in the Extra Pure RO-450 systems can last around 8 To 12 months between changes.
 
Filters are also identical and made by GE for Extra pure RO-450 water systems and Avantapure RO 450 Water systems (total six parts)
