The RO Membrane filters water down to the microscopic level, allowing nothing bigger than a water molecule through. Hydro-Logic membranes are standard equipment in our SP, CHP, MPRO, MPDI RO/DI, and the MPDW Drinking Water Systems. All 25 to 90 GPD membranes will fit in our standard membrane housing. The Standard Membrane is also available as a replacement option for most competitors' reverse osmosis systems. Replace membranes when product water decreases and/or ppm increase. Stealth RO150/300 membranes reduces 98%+ of total dissolved solids.

Replace the Hydro-Logic Stealth Membrane every 6 months to a year.
