AMI Direct Flow Tankless Reverse Osmosis Water Filtration System purifies water on demand and dispenses it directly to your faucet - without the need for a storage tank. Stage 1: 5 Micron Sediment Filter Removes Dirt, Rust, Sand, Dust, Silt, and other physical impurities from water down to 5 microns. This filtration stage also extends the life of the carbon filters and membranes in the later stages. The graded pore structure uses the entire depth of the filter - capturing larger particles in the outer layers and decreasing in size as it reaches the center. This maximizes the dirt holding capacity, giving more time between change-outs. Stages 2 & 3: Activated Carbon Block Filter for Powerful Chemical Adsorption & Flavor Enhancement Applied Membranes Inline Carbon Filters absorb chlorine, unpleasant tastes and odors, chloramine, and VOCs, along with 100s of other harmful chemical contaminants commonly found in tap water. Corrects turbidity (cloudy water) to ensure clear, fresh water and ice. Stage 4: Reverse Osmosis Membrane The RO Membrane is the heart of the RO System. The RO membrane reduces up to 99% of the total dissolved solids (TDS) from your water including arsenic, barium, cadmium, chromium (hexavalent), chromium (trivalent), copper, turbidity, fluoride, lead, radium 226/228, and selenium, while washing the rejected contaminants down the drain. The extra-high flow (25 gallons per hour) flow rate eliminates the need for a storage tank, and purify water as it is dispensed. The designer faucet included is easy to install, and fits most standard sinks. Simply follow the clear instructions and color-coded parts or have your local plumber install it for you....and, voila! You’ve got pure, filtered water to drink. Now you can have better drinking water, cooking water, and even better-tasting ice cubes. Replace the carbon filters every 6–12 months for the best-tasting water possible every day.
