Our carbon filters provide a higher absorption rate, due to the molecular structure of the pores, which allows even the smallest of particulates to be efficiently removed from your water. NU Aqua Reverse Osmosis Systems to provide up to a 99% rejection rate of 1000+ pollutants such as arsenic, chlorine, fluoride, and lead The NU Aqua Platinum Series UV and Alkaline reverse osmosis system is the premier home filtration system providing the safest and healthy water available. Typically municipal or city water is generally on the lower end of contamination and does not require the use of UV while well water or natural water sources are more susceptible and should always use ultraviolet purification. The 5-stage Alkaline and mineralization filter utilizes bio ceramic media, tourmaline, calcite, maifan and ORP balls to naturally increase the healthy minerals your body needs such as calcium, iron, zinc, magnesium, copper and selenium while boosting antioxidants and transforming the waters alkalinity. This 5-stage water filter for home use contains three pre-filters, one sediment filter and two HydrCoil Technology carbon filters formed from an ultra fine carbon mist forced through high pressure injection. These filters are produced with the finest and most resilient carbon media on the market. This process provides up to 50X betters absorption rate over standard carbon media and a longer filter life span. After the pre-filters the refined water is processed by the TFC reverse osmosis membrane where the remaining dissolved solids such as salts are removed. To ensure the best tasting water it's then polished by a post carbon filter before exiting the faucet and into your glass.
