Aqua Pure AP-RO 7000 Reverse Osmosis System A complete and reliable 7-stage reverse osmosis model with 11 liter storage tank for under the kitchen counter. Reverse osmosis technology is the best method of purifying tap water. The system's seven filtration stages achieve a drastic reduction of up to 97% of the following elements. Retains: Chromium, Chlorine, Arsenic, Aluminum, Ammonia, Copper, Mercury, Uranium, Pesticides, Phosphates, Bacteria, Barium, Benzene, Bicarbonate, Borate (boron), Bromine (bromide), Cadmium, Calcium, Carbon Dioxide, Carbontetrachloride, Chlorides, Color, Cyanide, Cyptosporidium, Fluoride, Giardia Lamblia, Hardness, Hydrogen sulfide, Iron, Lead, Legionella, Magnesium, Manganese, Mercury, Methane, Nickel, Nitrate, Nitrite, Odor, Organic substances, Potassium, Radium , Radon, Selentum, Silicon, Silver, SOC, Sodium, Strontium, Sulfate, THM, TOC, Dissolved solids, Turbidity, Viruses, VOCs, etc. More specifically, the system is equipped with the following seven filtration stages: 1st stage: APPR 5M sediment filter. It is made of 100% pure polypropylene fibers, high capacity and removes dirt, dust, particles, rust, soil, mud and other sediments. 2nd stage: Granular activated carbon filter APCBL 5M. It is a high performance granular activated carbon filter that removes 99% of free chlorine, pesticides, bad taste and odor, organic pollutant particles, chemicals and cysts. 3rd stage: Solid activated carbon filter Plus AP-CTO 975. Offers protection against a range of tap water contaminants, with an emphasis on the effective removal of volatile organic compounds, chemicals as well as cysts, up to 0.6 micron. Made of high quality activated carbon. In addition, thanks to the carbon block component it contains, it removes heavy metals such as lead, copper, mercury, strontium, arsenic and cadmium. In addition, it removes chlorine, pesticides, providing an excellent taste to the water, thanks to the coconut oil ingredient. 4th stage: Vontron's TFC (Thin Film Composite) high rejection 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, nitrates and selenium) . The pollutants are then removed through the drain. 5th Stage: AP-IC RO Carbon Aftertreatment Filter NSF approved, the aftertreatment filter removes all odors and debris that may be left in the water. It also improves the ph, smell and taste of the water. 6th stage: AP-IM RO enrichment filter Adds trace elements and mineral components to the water that are necessary for the body while at the same time favoring better absorption of water by the body. 7th Stage: Aifir 2000: ion enrichment filter Activates water molecules in the human body, improves oxygen levels, eliminates fats, chemicals and toxins present in the blood. As a result, it improves blood flow. Tank The water is stored in an 11 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 Pure AP-RO 7000 Home Reverse Osmosis System is the faucet that sits on the kitchen counter or sink. 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.
