Review: Amazing Filter!!! - I’ve been using the Frizzlife Reverse Osmosis Water Filter for a bit now and I’m honestly very impressed. The installation was much easier than I expected, and the tankless design saves a lot of space under the sink. The water flow is fast, and the taste difference is noticeable right away — clean, fresh, and no weird aftertaste. I really like the built-in display that shows TDS levels and filter life. It’s convenient not having to guess when filters need replacing. The alkaline remineralization is a nice bonus, and the water tastes great for drinking and cooking. Overall, the system feels well-built and high quality. It does exactly what it promises, and I feel confident about the water my family is drinking. I’d definitely recommend this system to anyone looking for a reliable under-sink RO filter.
Review: Reduces TDS greatly while adding beneficial minerals to water - I have a whole house iron filter and water softner to correct high iron from my well. My TDS from water test was at 265ppm. From my understanding, a water softner adds some sodium to the water. I bought this item to reduce my TDS in my drinking water, while adding benificial minerals at the same time. After installation, my TDS were reduced to 12ppm. Installation was pretty easy for me. I had a faucet from years past, and had drilled the hole thru the stainless sink with a special bit. The instructions are easy to follow and straight forward. My only issue was getting power to the sink area. Tapped into my dishwasher power line to provide power to fizzlife unit. Total installation time was about 2 hrs. There is a slight hum when using this unit, but barely heard from under the sink cabinet area. The water has a fantastic taste after running thru the Tam 3 ph mineralizer filter! Its a pleasure to drink slightly alkaline water, and much healthier with added minerals. Water output from the faucet is decent, not slow and not really fast but somewhere in the middle range. Its a good looking faucet and well made, not cheap. Overall I am completely satisfied that I purchased this unit and Highly recommend it to anyone looking for great tasting water. You wont be disappointed! Lastly, customer service is outstanding!!!! Had a small issue resolved in a matter of a day on a Sunday to boot. They really back their product and support the customer 100%

## Questions & Answers

**Q: Does anybody else get a higher TDS reading with a meter (100-200), but then drops back down to mid teens (13-19) after letting the water run a bit?**
A: Hi Luis, Thanks for inquiring with us! 
Osmosis is a natural phenomenon happens in all RO system, no matter if you have a conventional RO system or tankless RO system. When the RO system starts to work, pressure from the pump overcomes natural osmotic pressure, forcing feed water through the RO membrane that removes the impurities. When the RO system stops working, the pump stops offering pressure as well. At that time, because of different concentrations, a small fraction of ions will enter into pure water and cause TDS to rise by a small amount. However, even if the TDS reading is a little high at the beginning, the quality water is still unbeatable by any other filtration methods including carbon, KDF, ceramic, UF, UV, etc.. The water is totally good to drink and you don’t have to wait for about 1 minute to get the water, since the whole system will not release any harmful substances to the water. The TDS removing rate for PD600 is about 94-95%, if your incoming TDS is high, the outlet TDS will be high too.
Hope it helps, if you have any further questions, please feel free to contact us at: support@frizzlife.com
Best Regards,
Frizzlife Customer Service Team

**Q: is the alkaline remineralization filter necessary, can I connect filter directly to the faucet?**
A: Hi dear customer, the water from RO membrane is slightly acidic, which also removes natural mineral. It balances the alkalinity of RO water and adjusts the PH to more than 7.5. Drinking weakly alkaline water is beneficial to your health. It also restores health-benefiting essential minerals to your water. It will be totally fine if you don't want to use the TAM3, you don’t have to disconnect the tubing and the fittings on the TAM3. You only need to unscrew the TAM3 filter and the water still can go through. 
If you have any further question, please feel free to contact us anytime. 
Best Regards,
Frizzlife Customer Service Team

**Q: Does the unit need to be installed standing up vertically or can it be horizontal?**
A: Hi dear customer, thanks very much for your interest in Frizzlife reverse osmosis system. We are sorry to tell you our RO Filtration System cannot be installed horizontally. If you put it horizontally, the internal water circulation of RO system will be affected and most functions of RO system cannot be realized.

If you have any further questions, please feel free to contact us.

A: Hi, great questions, thanks for inquiring with us. The rated power for this unit is 85W. If you have any further questions, please feel free to contact us.

### ⭐⭐⭐⭐ Impressive filtration but a few issues
*by S***R on January 21, 2025*

I bought this Frizzlife filter to replace another brand tankless RO filter that malfunctioned after 18 months. Here’s my take when compared to the 3 other brand tankless RO filters I have: Pros: - Unit is solid and well built. Installation was easy. No issues. No leaks. - Water filtration is impressive: The TDS of my unfiltered city water supply is 330ppm with a ph of 7.2. This machine reads 6ppm after filtration but the alkaline filter increases it to 28ppm with a ph of 8.7. - The taste is quite good and I think a little better than the other RO filters I've owned. Taste is smooth and well-rounded with no sharpness. Cons: - It really doesn’t work at its best dispensing a single glass at a time. I need to dispense into a carafe and run about 30 seconds first to purge the water sitting in the alkaline TAM3 final stage. If I just filled a glass with glass without running it first, I would end up with a TDS of over 75 and a ph of 9.2 - There is NO phone or even chat support. To get help with a question I needed to email Frizzlife and wait for their mail reply. I had 2 quick questions, which could have been handed in a 2-minute phone call but it took me 4 days and several back-and-forth emails to get them answered - this was really disappointing. - This one makes slightly more noise. I put some vibration pads under the unit which helped. - When recovering from a power interruption, you need to run the filter for a few minutes straight to get the TDS meter working again. Overall would purchase again but still a little disappointing there is no phone support if I have a quick question.
