AV-DEMI-L Aqua Vita is a 2" linear cartridge filled with PUROLITE MB400 ion exchange resin (a mixture of cation and anion exchange resins) for water demineralization. Used after osmotic filtration, it helps achieve water with very low salinity, even 0 ppm (depending on operating conditions and water quality).
AV-DEMI-L Aqua Vita demineralization cartridge is a 2" inline cartridge designed for the final stage of water treatment in installations such as reverse osmosis, an osmotic filter, or a reverse osmosis system. The PUROLITE MB400 ion exchange resin filling helps effectively reduce the salinity level of water after membrane filtration, reaching even 0 ppm depending on water quality and operating conditions. It is a practical water filter for users who expect very high water purity in an advanced water filtration system.

AV-DEMI-L Aqua Vita was designed as a 2" inline cartridge for water demineralization. Its purpose is the final reduction of dissolved mineral content in water that has previously undergone osmotic filtration.
The cartridge is filled with PUROLITE MB400 resin, a mixture of cation and anion exchange resin. This composition enables water demineralization and the achievement of a very low salinity level. In practice, this means water suitable for applications where the highest possible purity is important after the work performed by a reverse osmosis filter.
The heart of the cartridge is PUROLITE MB400 ion exchange resin. It is a mixture of two types of ion exchange media:
The combination of both components allows the removal of ions responsible for water conductivity and salinity. As a result, the cartridge used after the osmotic membrane is an effective complement to the process carried out by a reverse osmosis system.
It is at this stage that it is possible to further “polish” the water after osmosis and achieve very low TDS values, even 0 ppm, depending on operating conditions and the quality of the water supplied to the system.
The cartridge is primarily used as a final component in systems based on reverse osmosis. It is installed after osmotic filtration when the goal is to further reduce the content of dissolved substances in the water.
This solution works wherever the standard operation of the osmotic membrane is not yet the target level and additional demineralization is needed. Thanks to this, AV-DEMI-L Aqua Vita can be an important element of a more demanding process such as precise water treatment.
The cartridge is used after osmotic filtration. Achieving salinity as low as 0 ppm depends on the system's operating conditions and water quality.
This model is a 2" inline cartridge, so before purchase it is worth making sure it is compatible with your water filtration system and connection method. Its role is not classic water mineralization, but the opposite process, namely demineralization after osmosis.
If the user's goal is to achieve the lowest possible TDS level after the RO set has done its job, such a cartridge may be the right addition to the installation. It works as a final stage improving water purity after passing through the osmotic filter.

| Product type | Demineralization cartridge |
| Design | 2" inline cartridge |
| Filter media | PUROLITE MB400 ion exchange resin |
| Media composition | Mixture of cation and anion exchange resin |
| Purpose | Water demineralization |
| Installation point in the system | After osmotic filtration |
| Result | Very low water salinity, even 0 ppm, depending on operating conditions and water quality |
It is a cartridge for water demineralization. It is used as a final stage after osmotic filtration to further reduce the level of dissolved substances and obtain water with very low salinity.
Yes. The cartridge is designed for use after the reverse osmosis process and complements the work performed by a reverse osmosis filter or a complete reverse osmosis system.
The cartridge is filled with PUROLITE MB400 ion exchange resin. It is a mixture of cation and anion exchange resin intended for the water demineralization process.
It means that two types of ion exchange resins work inside the cartridge to remove ions from the water. This combination allows effective salinity reduction and lowers the TDS value after osmotic filtration.
Yes, the cartridge helps achieve water with salinity as low as 0 ppm. However, the final result depends on the operating conditions of the entire system and the quality of the water entering the system.
No. This model is used for demineralization, meaning the removal of remaining ions from water after osmosis. It is not a cartridge responsible for water mineralization.
The cartridge is used after osmotic filtration. This is the final stage whose purpose is to further reduce water salinity after passing through the osmotic membrane.
You should verify compatibility with your system in terms of the 2" inline design and the installation method used in your water filtration setup. This is especially important if you are expanding an existing osmotic filter with an additional treatment stage.
