Mineralisation: Conventional reverse osmosis systems remove important minerals from the water along with harmful impurities. TAM4 under-sink filtration restores these essential minerals (such as zinc, calcium, iron, magnesium, potassium and more) in reverse osmosis water, ensuring your daily mineral intake. Please note that the minerals can contribute to a higher TDS value, but the treated water is much healthier than pure water with low TDS
Balance pH value to weakly basic: your body regulates the pH value closely at about 7.4 to maintain overall health, while the water is slightly acidic after RO filtration. To remedy this side effect of reverse osmosis water, the TAM4 Post Alkaline Filter System raises the pH + value of reverse osmosis water to over 7.5, which corresponds to your body's natural pH. In addition, the water gets a better taste
Automatic shut-off and replacement by turning: thanks to the automatic shut-off, you do not even have to interrupt the water supply when changing the filter. The twist-in design makes filter change a breeze. Each filter cartridge can produce 900-1000 gallons of mineralised and alkalized water, which is approximately equivalent to a use of 1 year, 2x longer than the average on the market.
3-in-1 composite filtration: the FRIZZLIFE TAM4 alkaline filter system combines alkaline particles, mineral substances and a carbon block in one filter set. In addition to reducing pollutants and polishing the favor, it relieves inherited side effects from conventional RO systems - Standard RO system not only removes harmful impurities but also important minerals from the water and makes it a bit acidic.
1/4 inch universal compatibility for RO systems: the FRIZZLIFE TAM4 alkaline remineralisation filter system is not designed as a standalone water filter, but is strongly recommended to treat pure water from the RO system. Comes with 1/4 inch quick connect hose, it is compatible with most reverse osmosis systems on the market. Fits APEC Water Systems ROES-50, RCC7, RO500, RO5DX, WD-G3, WD-G2 reverse osmosis system and much more.
