Pentair GRO-2550 Reverse Osmosis System



The Pentair GRO-2550 system includes the high recovery GRO-50 encapsulated membrane. The system includes a 5 micron sediment and carbon block prefilter that reduces sediment, odor and improves taste.

The carbon and sediment prefilters reduces the particles and chlorine taste and odor to prolong the life of the RO membrane. The RO membrane separates water molecules from dissolved salts and minerals. The RO filtered water is sent to the storage tank until you need it. When you turn on the drinking water faucet, the filtered water from the storage tank is sent through a carbon polishing filter which provides final taste and odor filtration before the water reaches your glass. Cleaner, fresher water whenever you want it!
