Due to the porous structure of the active carbon powder (it is estimated that 3 to 5 g of active carbon powder specific surface area equivalent to the size of a standard football field), activated carbon rod after firing a very dense, for tap water smell, the smell, more than chlorine and volatile organic compounds and other pollutants with high removal efficiency, some manufacturers of carbon rods can even filter in accordance with US standards NSF53 spore cysts, and can retain the minerals in the water, without the use of additional microfiltration, ultrafiltration, etc. filter media. First level: Microfiltration: microfiltration tap water to remove all kinds of visible / dust and impurities. These particulate matter from aging pipes, rust, household water purification equipment Which is good, roof water tanks secondary pollution and so on. Second level: compression carbon: compressed carbon to remove chlorine and organic impurities household water purification equipment, such as harmful pesticides. Organic compounds in water can absorb odor, color and odor, water disinfection by-products derived from these substances. Third stage: ultrafiltration: ultrafiltration to remove bacteria, viruses and spores and other substances in the water. Fourth grade: the filter life indicator: The internal device gear structure design, with the water through, so that an axially inner gear rotates on the motion until the outlet blocked, household water purification equipment prices, the water can not be , which is designed by calculating the total stroke over the water purifier, in order to ensure the water is safe. Household water purification equipment, the Han technology, household water purification equipment quality rankings provided by the Henan Science and Technology Co., Ltd. Han Yue.
