I used this filter for about a year to make water for a small 30 gallon aquarium. I've only had to change the 1 micron pre filter once. It still looks new and in excellent condition. It includes an optional membrane flush adapter so that you can flush the membrane before use.This will extend the life of the membrane. Also included are two brand new 1 micron sediment prefilter replacement cartridges. MaxPure MPDI 90 GPD 4 Stage RO/DI System with Standard 90 GPD RO Membrane, 1 Micron pre-filters, Color-Indicating SilicaBuster DI cartridge, pressure gauge & hose adapter. SpectraPure® 90 GPD MaxPure RODI System incorporates a high silicate removal TFC membrane, 1 Micron MicroTec Sediment and Carbon Block pre-filters and a custom formulated 10 inch Color-changing DI cartridge.
