GrowMax Water Deionization Filter Kit (DI) 10". For 0 ppm water

The GrowMax DI Filter Kit 10" was specifically developed to remove the last traces of dissolved salts from water. When combined with a GrowMax reverse osmosis system such as the Power Grow 500 or the Mega Grow 1000, this kit delivers a final result of 0 ppm EC – the ideal water quality for demanding applications.

Ultrapure water for sensitive applications

The DI kit is used wherever absolutely pure water is essential: in aquaria (marine and freshwater), hydroponic systems, the cultivation of sensitive plants , or technical applications in the laboratory. The kit uses a 10" mixed-bed resin cartridge to remove even the smallest amounts of dissolved minerals from the water.

Plug & Play – easy installation

Included in delivery are a wall mount, screws, 3/8" connections, DI housing , and a matching DI cartridge. Installation is quick and easy – the filter can be installed directly after a reverse osmosis system.

When does the DI cartridge need to be changed?

The replacement intervals depend heavily on the quantity and quality of the filtered water. Using an EC or TDS meter, you can easily check when a replacement is necessary: ​​As soon as the EC value rises above 0 ppm, the cartridge should be replaced. Suitable replacement: GrowMax DI cartridge 10" .
