Main highlights

Smart LED display and easy installation: The smart display clearly shows TDS in real time and the remaining life of each filter. The built-in TDS meter constantly monitors the quality of your drinking water. The colour-coded indicators remind you to change the filters in advance. With all the included parts and well-organised instructions and videos (English language not guaranteed), the FRIZZLIFE PD600 RO filter can be completely installed by yourself in 20 minutes.
Remineralisation and alkalisation: The water from the RO membrane is slightly acidic, which also removes natural minerals. The 3rd filter level of the system balances the alkalinity of RO water and adjusts the pH value to over 7.5. Drinking weak alkaline water is good for your health. It also restores health-promoting essential minerals. Frizzlife PD600 produces healthy and tasty water for you.
No tank design: The FRIZZLIFE PD600 with countercurrent filter has a tankless design. The compact and slim filter system with a smaller and more comfortable base area takes up less space and saves storage space under the kitchen sink. No tank also means no secondary pollution. Guaranteed high purity, safe and clean water for you and your family.
Low drain ratio: Thanks to advanced water-saving technology, the FRIZZLIFE PD600 RO system maximises efficiency and can save you up to 50% water compared to conventional RO filter systems on the market. It is both economical and environmentally friendly and makes your water bills more affordable. Over the life of the system, the PD600 RO filter system even pays for itself with water saving!
2271 LPD high water flow: The PD600 filter system contains a powerful internal pump that can produce 2271 litres of water per day. The high capacity can meet the daily water needs of the extended family. The water flow is fast and stable. The system can fill a 330 ml cup of water in about 10 seconds. Enjoy endless fresh water from your tap!
