5 Stage RO Filter Replacement Pack with 3/8 push fit 4 piece
FITS MOST STANDARD RO SYSTEMS
Set includes 2 carbon filters, 1 sediment filter and 1 upper polishing filter with a 3/8 inch push-fit. This set is yearly.
Membranes are sold separately and should be changed 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.
Fits R/O units that look similar to this although filter housing may be white, clear or even black. This set also fits the 400 gpd series.
