STANDARD RO Filter Replacement Pack with 75 Membrane (fits 50, 75, 80 gpd)

FITS MOST STANDARD RO SYSTEMS

Set includes 2 x 5-micron carbon filters, 1 x 5-micron sediment filter and 1 TFC (thin film composite) 75 gallon per day Membrane. Most Reverse Osmosis Drinking Water Systems require a new Membrane every 3-5 years and a set of filters every year. 

How can you tell it's time to change the Membrane? Two signs that your membrane is failing are these: water production slows down to a trickle or the water has an "off" taste. Generally, under normal use, if your unit is installed on a SOFT water line (as it should be), your membrane will last the full 5 years. If it's hooked into a HARD water line, expect to replace your membrane every couple of years if not sooner. 

Due to delivery disruptions, the membrane in this set may be substituted with blue (Filmtec), white (Pentek) or black (Black Max). All are interchangeable.

Fits R/O units that look similar to this although filter housing may be white, clear or even black.
