HydroPure™ Deionizer System

The lowest cost source of pure battery water!

The system comes with everything you need to make your own pure water right from your own tap: a wall-mounting plate, one high-capacity Deionizer cartridge, purity light, hose hanger, quick connects and input and output hoses. Installation takes just minutes — and replacing spent cartridges takes just seconds.

Battery water should be free from metallic impurities because they can affect cell voltages and self-discharge. Also to be limited are calcium and magnesium compounds found in hard water because these may cause mossing and dendrite growth through the separators. Note that these impurities are dissolved in the water and cannot be removed by conventional filters.

Features Specsifications FAQs

Professional quality deionizers: Not just a filter, which only removes particles, but a real ion-exchange medium which electrostatically removes dissolved impurities. Purity is comparable with distilled water and ideal for batteries.

Our Deionizer system reduces the high price of buying bottled water and is more convenient as well.

How does it work?

Inside the Deionizer, tap water is passed through a cartridge containing beds of cationic and anionic resins which electrostatically remove impurities. The result is very pure water. When the cartridge becomes exhausted it is simply replaced with a fresh one.

Purity Chart

The following chart can be used to determine how many gallons of pure battery water can be obtained from one cartridge based on the purity of the incoming tap water.

Purity of Tap Water	Total Dissolved Solids			Cartridge Capacity
	PPM	Grains	uS/cm	U.S. Gallons	Liters
Good	50	3	28	1440	5,451
Good	75	4	42	960	3,634
Average	100	6	56	720	2,725
	120	7	67	600	2,271
	150	9	84	480	1,817
Poor	200	12	112	360	1,363
Poor	250	15	140	288	1,090

I have installed the HydroPure Deionizer, but the purity light is flashing red, why is this?

Before first use, run 10 gallons / 40 liters of water and check again.

If you are using the deionizer to fill a watering cart or a bucket, be sure to have the flow restrictor connected to the end of the output hose. The water needs enough time to interact with the resins inside the cartridge to deionize effectively.

If the problem persists, remove the purity light from the deionizer and leave it to dry in open air for 30 mins, if the light is still flashing red in the open air you will need to replace the purity light.

If the purity light flashed green in the open air, please contact customer service to help diagnose the issue.

How much water can I expect out of one cartridge?

The capacity of the cartridge is directly related to the purity of the incoming water, or TDS level. To determine what the capacity will be precisely, you must test the incoming water with a TDS meter. Using the Cartridge Output Calculator at the bottom of the page, enter in the resulting Parts Per Million data to see how many gallons/liters you will get from your cartridges.

Can I connect the Deionizer to a Water Injector System?

No, the Injector system requires consistent 25-35 PSI to function properly, which the deionizer cannot produce.

What is the shelf life of the cartridge?

The deionizer cartridge has a shelf of 5 years.

How long can I extend the length of the output hose?

If connecting to a Stealth system, the maximum length is 100 ft.

If connecting to a Watering Gun (GUN-X, GUN-S, GUN-RR), you must confirm that your flowing water pressure is at least 30 PSI which will allow you to extend the output hose up to 100 ft.
