key Features
【SUPERIOR FILTRATION PERFORMANCE】Frizzlife PX500-A under sink tankless reverse osmosis water filtration system has a RO membrane (ASR313-500G) with precision at 0.0001 micron, which eliminates more than 1000+ kinds of contaminants (99.99%) from water including fluoride, chlorine, chloramine, TDS, limescale and lead&other heavy metals. The pre-filter(ASR311) greatly prolongs the service life of the RO membrane while the post alkaline filter(ASR313-A) remineralizes the pure water.
【TANKLESS DESIGN】 With a high capacity of 500 Gallons per day (GPD) vs. Conventional 50 GPD, Frizzlife PX500-A RO water filter abandons the traditional water tank. It takes up to 60% less space under the counter and swipes out the secondary pollution caused by the unventilated tank. The direct water flow can reach up to 0.35 GPM@ 60psi. The system could also be hooked up to your refrigerator by using IMC-1 (B07R7NH55L) to providing you crystal and healthy ice cubes.
【EASY DIY INSTALLTION】 Comes with filters loaded, Frizzlife RO water purification system is an integrated RO unit without a tank nor massive connection points. Fewer leakage concerns! It can be installed all by yourself in a breeze following a step-by-step installation video and comprehensive instructional user manual. Everything needed for installation is included in the package including a brush nickel faucet set! Save money from plumber hiring!
【FILTER LIFE REMINDER & QUICK CHANGE】 A filter life monitor is embedded in the operation panel. Blue light stands for good while red represents for low life, and it will beep when a change is needed. The replacement of Frizzlife RO water filtration system takes only 2 sec by a SINGEL TWIST. Change the 1st per 6 months, the 3rd stages per 12 months, and the 2nd RO membrane per two years. Frizzlife mini tank (B08P6RF58J) is also now available for solving the pulsing of the system due to unstable water pressure.
【REMINERALIZATION & SUPER LOW DRAIN RATIO】 One more step beyond pure water towards healthy, the 3rd stage of the RO system could alkalize pure water by adding back essential minerals and raise the pH to more than 7.5. Moreover, the system saves more than 450% waste water when compared to conventional RO systems. By generating 2 cups of pure water, only 1 cup of waste water would be drained, saving your bill and water.

- One of the unique selling points of the RO system is its alkalizing and remineralizing function. It's a step beyond pure water toward ultimate long-term health. By using natural, elemental small stones and particles, the post-filter mimics the mineral stones found at the bottom of the spring lake, restoring essential minerals and alkalizing the water's pH to over 7.5.
- Thanks to its high 500 GPD capacity, the Frizzlife tankless PX500 can provide your family with instant fresh water from the tap and fills a cup of water in 12 seconds. Frizzlife also offers a matte black finish for the face.


- The color-coded indicators remind you to change the filter cartridges in a timely manner. Blue means good, while red indicates a filter change. The first (ASR311) should be changed every 6 months, while the second RO membrane (ASR312) should be changed every 2 years, and the third (ASR313) every 12 months.
- The advanced RO filtration technology of the Frizzlife PX500 tankless purification system saves up to 450% water compared to other brands on the market. Producing 1.5 cups of purified RO water produces only 1 cup of wastewater.
