External Water Filter

This Inline Pre/Post Membrane Filter Cartridge is made with premium coconut shell based activated carbon. Inline post carbon filter is known as polishing filter, because it is usually the last stage of any standard reverse osmosis circuit. Being made of high quality coconut shell, it stabilizes the water tasting qualities and further removes any traces of bad tastes and odors. This filter is often used as a Reverse Osmosis (RO) inline post filter. It clips on to the membrane housing and filters the water after the bladder tank, acting as a polishing filter.
