Aqua Filter Reverse Osmosis System RX62135316NN A complete and reliable six-stage reverse osmosis model with a 12 liter storage tank for placing under the kitchen counter. Reverse osmosis technology is the most perfect method of purifying tap water. All our company's systems are easy to install and maintain so our customers can easily and economically use our filters for many years. All the filtration materials of our systems are fully certified according to the strictest standards (NSF, FDA, I.SO), while our suppliers are distinguished members of the Water Quality Association. The six filtration stages of the RO eco system achieve a drastic reduction of up to 97% of the following elements: Chromium, Chlorine, Arsenic Aluminum, Ammonia, Copper, Mercury, Uranium, Pesticides, Phosphates, Bacteria, Barium, Benzene, Bicarbonate, Borate (boron), Bromine (bromide), Cadmium, Calcium, Carbon dioxide, Carbontetrachloride, Chloride, Color, Cyanide, Cyptosporidium, Fluoride, Giardia Lamblia, Hardness, Hydrogen sulfide, Iron, Lead, Legionella, Magnesium, Manganese, Mercury, Methane , Nickel, Nitrate, Nitrite, Odor, Organics, Potassium, Radium, Radon, Selentum, Silicon, Silver, SOC, Sodium, Strontium, Sulphate, THM, TOC, Dissolved Solids, Turbidity, Viruses, VOCs, etc. a 6 Filtration Stages: 1st stage: Sediment filter 5 mic. It is made of 100% pure polypropylene fibers, high capacity and removes dirt, dust, particles, rust and other sediments. 2nd stage: Granular activated carbon filter. It is a high efficiency activated carbon filter that removes 99% of free chlorine, odor, organic pollutant particles, insecticides and chemicals. 3rd stage: 20 mic sediment or activated carbon filter Depending on the water quality, the third stage can be either activated carbon or 20 mic sediment to best prepare the water before passing through the high rejection membrane. The sediment filter is made of 100% pure polypropylene fibers, high capacity and removes chemical compounds, suspensions and other sediments that are not retained due to their size from the 1st stage. 4th Stage: High Rejection TFC (Thin Film Composite) Membrane Separates 95-99.9% of dissolved pollutants, chemicals, solids, metals, bacteria and microbes from water molecules (see lead, copper, barium, chromium, mercury , sodium, cadmium, fluoride, nitrites and selenium). The pollutants are then removed through the drain. 5th stage: Carbon post-treatment filter NSF approved, the effluent filter removes all odors and debris, improving the ph and taste of the water. 6th stage: Water enrichment filter with trace elements and minerals The 6th stage adds trace elements and minerals to the water that are necessary for the body while at the same time favoring the better absorption of water by your body. Tank The water is stored in a 12 liter tank. Inside the tank is a balloon-like rubber diaphragm that is inflated with air to a pressure of 8-10 psi. As the container fills, the air pressure increases and the water is pushed out when the faucet is turned on. Outlet Faucet The final element of the Aqua Filter RO eco Home Reverse Osmosis System is the faucet that sits on the kitchen counter or sink.
