Description
The DEMI Purolite MB400 water demineralization filter is a linear cartridge designed to work as the final stage in systems such as reverse osmosis, an osmosis filter, or a complete reverse osmosis system. Installed after the RO membrane, it helps achieve water with 0 ppm TDS, which makes it suitable wherever a very low level of remaining dissolved salts matters. It is a practical solution for users expanding a water filter and the entire water filtration system with a final demineralization stage.
Final water demineralization after reverse osmosis
The DEMI linear cartridge is filled with Purolite MB-400 resin, designed for water demineralization. This reverse osmosis filter is installed as the last stage of the system, after osmosis filtration, to remove the remaining ions still present in the water after the membrane.
Purolite MB400 is a mixture of cation and anion exchange resin. Thanks to this, the bed works as a demineralizing resin that effectively lowers water salinity and helps achieve a 0 ppm reading at the filter outlet.
For the user, this means an easy expansion of the existing water treatment system with an additional “polishing” stage after RO, without the need to replace the entire installation.
Main benefits
- final water demineralization stage after osmosis filtration,
- Purolite MB-400 resin, a mixture of cation and anion exchange resin,
- helps achieve water with 0 ppm TDS,
- 2" linear format makes it easy to integrate the cartridge into a reverse osmosis system,
- the set includes the mounting accessories needed for connection,
- a practical solution for expanding a reverse osmosis filter with an additional water treatment stage.
Application
The DEMI Purolite MB400 filter is designed for installation after a reverse osmosis system. It works best as the final filtration stage when the goal is as complete a water demineralization as possible and reducing the final TDS to 0 ppm.
It is a suitable choice for users who want to expand a water filter or reverse osmosis system with a final polishing stage. Unlike solutions responsible for water mineralization, this cartridge is intended to remove the remaining ions, not replenish them.
Set contents
- 1x DEMI linear filter with MB-400 resin
- 2x connector bracket for 2" linear filters
- 2x 1/4" male thread x 1/4" tubing elbow
- 1.5 m of 1/4" tubing
Construction and operating principle
The cartridge has a linear design with a 2" diameter and a height of 10". Inside there is about 0.4 l of Purolite MB-400 resin. The bed in the form of a mixture of cation and anion exchange resin is responsible for water demineralization by capturing the remaining ions present after the osmosis membrane has done its work.
In practice, this means that after passing through a standard osmosis filter, the water goes to the DEMI cartridge, which serves as the final purification stage. Such a setup is especially useful wherever a very low salinity level is required.
The DEMI cartridge should be used after osmosis filtration, as the last stage in the system. The operating temperature range is 2-42 °C. For correct installation, use the included accessories and 1/4" tubing according to the flow direction in the installation.
Why choose the DEMI cartridge with Purolite MB400 resin
This solution is intended for users who expect more from a reverse osmosis system than standard purification. Adding the DEMI stage makes it possible to achieve very low salinity, and thanks to the included accessories, the set can be used to expand an existing installation.
The 2" x 10" linear format and the included mounting components simplify integration with the RO system. It is a practical component for those developing a water filtration system with a final demineralization stage.

Questions
What is the DEMI Purolite MB400 filter used for?
It is a linear cartridge designed for water demineralization. It is used after reverse osmosis as the final filtration stage to remove the remaining ions and help achieve water with 0 ppm TDS.
Is this cartridge installed before or after the osmosis membrane?
The DEMI cartridge is installed after osmosis filtration, as the final stage of the system. Its purpose is not pre-filtration, but final water demineralization after the RO membrane.
What resin is inside the filter?
Inside there is PUROLITE MB-400 resin. It is a mixture of cation and anion exchange resin designed for water demineralization.
How much resin does the cartridge contain?
The filter contains about 0.4 l of demineralizing resin.
What are the cartridge dimensions?
The cartridge height is 10" and the diameter is 2". It is a linear 2" filter designed to be integrated into an installation with 1/4" tubing.
What is included in the set?
The set includes: 1x DEMI linear filter with MB-400 resin, 2x connector bracket for 2" linear filters, 2x 1/4" male thread x 1/4" tubing elbow, and 1.5 m of 1/4" tubing.
At what temperature can the filter operate?
The operating temperature range is from 2 to 42 °C. Under these conditions, the cartridge should be used in a standard water treatment installation.
Is the DEMI filter used for water mineralization?
No. This model is used for water demineralization, meaning the removal of remaining salts and ions. Its operation is the opposite of cartridges responsible for water mineralization.
Is this product suitable for expanding an existing reverse osmosis system?
Yes, the set was prepared specifically with expanding a reverse osmosis filter with an additional DEMI linear cartridge in mind. The included brackets, elbows, and tubing make installation in an existing system easier.
