A MESH electrode / plate uses the same principle as the slotted electrode plate, but improves upon it by providing cross-channeling
to more evenly direct electron flow. The applied current more evenly saturates the electrode plate, increasing the effective delivery of electrical current to create better alteration/ionization in your alkaline water. MESH electrode/water ionization plate technology is just like the best irrigation systems

Plates Automatic Cleaning System

Automatically initiates a cleaning cycle for electrodes  after each water ionizer use, so you don’t have to wait for any inconvenient cleaning discharge cycles.

Because Prime Water ionizers do not use DARC electrode autocleanse technology, cleaning the electrodes with acid vinegar or citric acid is also recommended from time to time (every 3 months for 20 mins – water ionizer cleaning pump included in package)

Prime Water Electrodes DURABILITY – 10 years

Are you worried about durability for these large electrodes? Durability Test Conducted for Electrodes ; According to the analysis of the test results:
The tests were performed according to standard test methodology.
After each test was taken according to the different water flow rates and comparing the analysis to a range of standards, even when not using the standard amounts, water cell life was ten years

prime 501 r water ionizer smps 300 W

one of the most advanced power delivery systems on the market to insure that your water ionizer is producing the most powerful ionized water for years and years to come.

Unlike the old outdated transformers, the next generation SMPS system has been shown to last longer and run cooler. With the most up to date technology, you’ll never have to worry about the pH or ORP levels of your ionized alkaline water ionizer.

Worried about so much watts ?

Prime R water ionizers usually use a SMPS max  power 450Watts, but don’t worry, when we test in factory Max used watts  were about 350 Watts for 13 electrodes water ionizer and 280 watts for 9 electrodes / plates water ionizers….about 160 Watts for 5 plates used on ALK4

here are the data for 13 electrodes water ionizer from PRIME water

Level-1 alkaline ionized water: 20 Watts

Level-2 alkaline ionized water: 40 Watts

Level-3 alkaline ionized water: 100 Watts

Level-4 alkaline ionized water : 350 Watts (13Plates) 

5 Plates /electrodes water ionizer aprox Max Watts – 160 Watts when level 4 alkaline water selected .

Prime R water ionizers allows you to program nearly any pH and ORP combination, so as to customize your pH and ORP level that’s right for you.

The higher you pH value, the higher ist also the dissolved hydrogen dH2 (up to 1200 ppm!).

Prime R water ionizers allow users to select from 1680 pH and ORP levels

Multi-Stage Media  DUAL water  Filtration System

The Prime 501 R Dual water filtration system is made up of multi level /stage specialized media water filter and a premium activated carbon water filter.

The Premium Activated Carbon water filter is structured to improve the reduction of heavy metals and fluoride found in many city water sources.

The silver activated carbon portion of the water filter kills bacteria and keeps them from growing within the water filter and being passed through to the electrolysis chamber.

The multi level stage sediment water filter reduces additional sediment particles in the water
