The Frizzlife PD600-TAM3 is an excellent tankless under sink reverse osmosis water filtration system that scores very well in our rankings of both the best tankless RO systems and the best undersink RO systems overall.
It has a very high daily throughput of 600 gallons per day (GPD) and 7 stages of water filtration, including an alkaline remineralization stage and a great wastewater ratio.
An integrated “smart” TDS meter gives you constant feedback about the quality of your water.
Plus, since this system is tankless, it is smaller and easy to maintain under your sink.
Tankless reverse osmosis systems offer a compact, integrated system contained in a sleek housing instead of the pressurized water storage tank and exposed system components of traditional RO systems.
The PD600 system requires an electrical outlet (100-240v) to power an internal pump that provides water pressure without a storage tank.
Since there is no storage tank, the system case takes up only a fraction of the space under your sink. In addition, access to the replaceable filters is presented on the front side of the case, making filter changes very quick and easy.
The Frizzlife PD600 achieves a very good ratio of 1 gallon of waste water for every 1.5 gallons of filtered water (1.5:1). This is almost as good as an RO system can provide and much better than most other systems. Wastewater is a normal byproduct of the reverse osmosis process and it is sent down sink’s drain pipe.
Here, we present and review the PD600-TAM3 version of the PD600, which is the standard PD600 system with the addition of the Frizzlife TAM3 alkaline remineralization filter packaged as a bundle.
It’s uncommon for tankless RO systems to include a remineralization stage and many people prefer it.
The purpose of a remineralization stage is to add some of the natural and beneficial trace minerals back to the water after is has been filtered. This stage also includes an extra coconut shell activated carbon block to “polish” the final taste.
The minerals added are:
The reverse osmosis (RO) membrane is so effective that any minerals present in the source water are removed, which lowers the pH of the filtered water and makes it more acidic.
When the remineralization stage adds these minerals back, the pH is raised into the alkaline range (7.5 or higher), which is considered healthier. This also gives the water a more smooth, mineral water taste.

Another benefit of this powered system is the integrated “smart” TDS meter located on the front faceplate of the system case.
TDS (or Total Dissolved Solids) is a measurement of all particles present in water. While not all particles are bad, TDS is a general indication of how pure the water is.
A good water filtration system like this will lower the TDS in water from hundreds down to single digits and with an integrated meter, you will always know how effective the system is at removing contaminants.
When the filters are due for replacement, the system will notify you and the TDS readings may increase as the aging filters become less effective.
Traditional RO systems require you to shut off the water supply, drain the system, and then remove the filters or filter housing with special wrenches or at awkward angles under your sink.
Tankless systems like the Frizzlife PD600 present the filters right in the front of the system.
You simply remove the faceplate, twist out the older filter and then twist in the new filter without any additional steps or possible water leakage.
Plus, smart filter life indicators on the faceplate let you know when a filter is near end of life or past due for replacement. When there is less than 5% remaining on a filter, the indicator light will blink red. When there is 0% left, the indicator light will stay red and an audible system buzzer can be heard.
The alkaline remineralization stage is installed along the filtered water line between the filtration system and dedicated faucet, so changing it is just as easy.
Of the three filter cartridges used by the Frizzlife PD600, two need to be changed once per year and one only needs to be replaced once every two years. We link to the necessary replacement filters further down this page.
All undersink reverse osmosis systems require a hole in your sink or counter top for the dedicated filtered water faucet.
Besides that, the setup and installation of the Frizzlife PD600 is very easy and straight forward. Anyone with general DIY skills and basic tools can set it up in less than an hour.
The package comes with a lot of nice extras like a longer faucet stem for thick counters, extra tube connectors and elbows, and a very sturdy mounting bracket for the remineralization filter.
- Compact, tankless design
- Alkaline filter to remineralize the water
- Smart TDS meter and filter life indicators
- Excellent daily throughput of 600 GPD
- Very good wastewater ratio
The PD600 is a great system but could be even better.
- No smart faucet with filter life indicators
- Not the best waste water ratio
- Remineralization filter is pretty big
- All tankless RO systems need help to power an ice maker but Frizzlife offers the Mini Tank (described below) to solve this problem.
Frizzlife makes a really nice collection of undersink and countertop reverse osmosis filters.
If you want the benefits of a compact, easy to manage tankless system, with smart features and an alkaline remineralization filter, then this is the one to get.
Plus, the price is great compared to the competition!

Frizzlife PD600 Replacement Filters
You can refer back here to order replacement filters as necessary. It may help to order your Stage 1 and 3 filters now so you are ready when the filter indicator light turns on in about 12 months.
The Frizzlife PD600 system will show an indicator light on the front faceplate when a filter is nearing its end of life. That is the time to come back here and order the necessary replacement filter.
- The Stage 1 filter cartridge should be replaced once every 12 months
- The Stage 2 filter cartridge (which includes the RO membrane) should be replaced once every 2 years
- The Stage 3 filter cartridge goes in the remineralization filter and should be replaced once every 12 months
Frizzlife Mini Water Tank For Reverse Osmosis Systems
Frizzlife makes the model MWT3 mini water tank to help solve one of the only problems associated with tankless RO systems… lack of pressure for a refrigerator or ice maker connection.
If you have a water dispenser or ice maker in your refrigerator, it makes sense to use the same pure, clean filtered water from your RO system to feed these devices.
It’s easy to run an extra water hose from your RO system to the fridge, but tankless RO systems usually don’t provide high enough water pressure over long distances or for the short time an ice maker draws water.
The Frizzlife Mini Water tank solves this problem by offering the MWT3 mini tank.
Install this between your RO system and the refrigerator to maintain a higher level of water pressure and help with ice makers and water dispensers.
This mini tank works with ANY RO system and can be used to improve the water pressure on your existing tankless reverse osmosis water filter.
