This DEMI cartridge holds about 0.6 L of MB20 mixed-bed resin and is meant for the last stage of water treatment, after reverse osmosis. It suits marine aquarists who need water with no dissolved minerals before mixing salt, where mineral content would affect sensitive marine organisms.
Why it matters
- Mixed-bed resin: the cartridge contains a blend of cation and anion exchange resins, which removes dissolved minerals from the water passing through it.
- Target of 0 ppm: the supplier states the filter is designed for water with a salinity of 0 ppm after demineralization.
- Flow rate: it operates at flows up to 4 L/min, so it can be used in a standard setup without slowing the system.
- Capacity depends on input water: output is rated at up to 1000 L, with the actual figure depending on the quality of the water entering the cartridge.

Frequently asked questions
No. Water after demineralization is not suitable for consumption, so it should be used only for purposes where the supplier intends it, such as marine aquaria.
It is intended for final demineralization after osmotic (RO) filtration. The cartridge contains a mix of cation and anion resin (about 0.6 L) that removes minerals, and the supplier aims for 0 ppm salinity in the output.
It uses a standard 10" x 2½" size, which the supplier says fits most housings available on the market.
The filter works at a flow rate of up to 4 liters per minute.
Capacity is up to 1000 liters, but it depends on the quality of the input water, so feeding it pre-filtered RO water will affect how long it lasts.
