iSpring RO100 5-Stage 100 GPD Under Sink Reverse Osmosis Drinking Water Filtration System 1:1 Pure to Waste Ratio with US Made Filters

The RO100 is a multi-layered filter system that provides optimal protection against over 1,000 contaminants, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.

The system consists of 5 different stages, each one designed to progressively remove contaminants and improve water quality, all the filter and RO membrane are made in the U.S.A.

• 3 Pre-filters: PP sediment filter. Carbon KDF (GAC) filter. Carbon block (CTO) filter. They remove large contaminants and protect the RO membrane from chemicals like chlorine and chloramines.


• The heart of the system is the 100GPD Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but virtually nothing else.


• Fine Activated Post Carbon filter provides final polishing before the purified water is delivered to the faucet.


• The end result is bottled-water quality, with no "hardness" and no sodium.
