Choosing the Best Frizzlife RO System

1. Frizzlife PD600-TAM3 Reverse Osmosis Water Filtration System

The Frizzlife PD600-TAM3 is a highly efficient tankless under sink RO System with a capacity of 600 gallons. It comes in a compact and sleek footprint, taking less space under the sink.

No tank also means no secondary pollution.

The system filters water in 7 stages and removes 99.99% of water contaminants. Some of these water pollutants include lead, fluoride, mercury, chlorine, chloramines, arsenic, and much more.

The PD600-TAM3 has a very high water production rate of 600 gallons per day. Water flows fast, and the system can fill a cup of 330ml within 10 seconds.

The high capacity and fast water flow rate make the unit ideal for a large family.

One disadvantage of RO systems is that they waste a lot of water. This, however, isn’t the case with the PD600-TAM3. It has a low drain ratio of 1:1.5. Only a gallon goes to waste for every 11/2 gallons of water produced.

It is both economical and environmental-friendly.

As RO systems filter contaminants from the water, they strip it off essential minerals as well. Remember that these minerals are not only beneficial to your health but also make the water tasty. The system’s 3rd stage filter (remineralization filter) solves this problem.

The alkalization filter reintroduces all essential minerals into the RO water raising its pH to more than 7.5.


  • Has a smart LED display that tells real-time TDS
  • Comes with all parts for easy installation
  • Removes up to 99.99% of water contaminants
  • Has fast water flow rate
  • Small and convenient footprint
  • Has a remineralization and alkalization filter
  • Saves water up to 450% compared to conventional systems


  • No filter life indicator

2. Frizzlife PX500-A Alkaline Remineralization Reverse Osmosis System

The Frizzlife PX500-A includes 3 filter cartridges and 7 filtration stages. It removes 99.99% of 1000+ contaminants from the water.

The pre-filter (ASR311) eliminates large particles like sand, silt, and rust. This stage is vital as it helps prolong the life of the RO membrane.

Although tankless, this system is quite efficient and will supply any large family with enough water per day. It produces 500 gallons of water per day and has a filtered to waste water ratio of 1.5:1.

And just like the PD600-TAM3, this system comes with an alkaline filter, the ASR313-A, that remineralizes the RO water. Thanks to this post-filter, you get to enjoy great-tasting water.

The selling point for this system is probably the fact it features a filter life reminder. The monitor comes embedded in the operation panel to remind you that it’s high time you changed the filters.

Blue light means that it’s all good, but red light indicates that you need to change the filter as soon as possible if you want to continue taking pure water.

And do you know that you can hook the system to your refrigerator using an IMC-1 ice connection kit?

The PX500-A Frizzlife comes with filters loaded and doesn’t have massive connection points. It’s therefore easy to install with basic DIY skills.

The RO-K3-A utilizes 7 layers of filtration elements to filter water effectively. In the first filtration stage, a K3-F-800 filter reduces larger particles such as sand and silt from the water.

The pre-filter preconditions the water and prolongs the life of the other filters.

In the 2nd filtration stage, the K3-G-100, RO membrane eliminates 99.99% of contaminants in the water, including VOCs, chloramines, chlorine, etc.

The TD-9 post carbon filter is an alkaline remineralizing filter that restores the essential minerals removed from your water during filtration.

Following an instruction manual that comes with the system and online tutorial videos will help you install the unit in a few minutes.

And since the filter cartridges come in a twist design, you can change them with ease using the wrench provided. The filter housing is also thickened hence sturdy enough for heavy-duty.
