Aqua Pure APROPM 5400 Reverse Osmosis System A complete and reliable six-stage reverse osmosis model with a pump and 11 liter storage tank for installation under the kitchen counter. Reverse osmosis is the best method of purifying tap water. The six filtration stages of the system achieve a drastic reduction of up to 97% of the following elements: Chromium, Chlorine, Aluminum Arsenic, 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. Also, Hydrogen Sulfide, Iron, Lead, Legionella, Magnesium, Manganese, Mercury, Methane, Nickel, Nitrate, Nitrite, Odor, Organics, 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 six 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: APCBL granular activated carbon filter. 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: APCLC solid activated carbon filter. It 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, down to 0.5 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 400 GPD 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, nitrates and selenium) . The pollutants are then removed through the drain. 5th Stage: AICRO Carbon Post-Treatment Filter NSF approved, the post-treatment 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: AIMRO enrichment filter Adds trace elements and minerals to the water that are essential for the body. At the same time, it favors better absorption of water by the body. 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 APRO 5400 Home Reverse Osmosis System is the faucet. Places on the kitchen counter or sink. All our company's systems are easy to install and maintain. So that our customers can easily and economically use our filters for many years.
