RO3 Aqua Vita VONTRON 150gpd aquarium filter is an efficient reverse osmosis filter for preparing water with very low hardness and conductivity. This reverse osmosis system is equipped with a VONTRON 150 GPD membrane, locking quick-connect fittings, and a complete set of connections, making it ready for efficient installation and convenient use. It is a practical osmosis filter for freshwater and marine aquatics, as well as a solution supporting precise water treatment in household applications.

RO3 Aqua Vita is an original aquarium filter with a Vontron 150 GPD membrane and a capacity of up to 570 liters per 24 hours. The system is designed to improve water quality using reverse osmosis, considered one of the most advanced water purification methods.
The filter removes up to 98% of contaminants present in water, including mechanical impurities, dissolved compounds, and microorganisms. In practice, this means it can prepare water for use in marine and freshwater aquatics when the goal is to obtain water with zero general hardness, low pH, and almost zero nitrogen compound content.
The design uses quick-connect fittings on the inline filters, which significantly simplifies installation and later servicing. The quick-connect fittings have additional protection in the form of a sealing mechanism lock, so operating the system is not only convenient but also safe during everyday use.

The filter is already prepared for installation, and its design allows for self-service maintenance. It is a solution for people who want an effective water filter without complicated installation.
The water obtained from this system can be used not only in aquatics. It is also suitable for cosmetic purposes, laboratory applications, and for use in steam irons.
*The final effect depends on the parameters of the filtered water and the operating conditions of the system.

The 3-stage RO3 Aqua Vita system combines pre-filtration with the operation of an efficient osmosis membrane. Each stage performs a specific function and affects the quality of the produced water.
Inline cartridge made of polypropylene foam. It is used to filter sand, silt, rust particles, and other solid contaminants from drinking water, effectively protecting household appliances. The cartridge should be replaced at least every 6 months.

The inline carbon cartridge removes contaminants such as chlorine, chlorine compounds, and organic impurities from water. The cartridge should be replaced at least every 6 months.
The osmosis membrane is made of semi-permeable thin-film membranes. Combined with polypropylene nonwoven and activated carbon filters, it makes it possible to obtain truly clean water. The osmosis membrane removes up to 99% of all compounds dissolved in water, as well as bacteria and viruses. The estimated membrane service life is about 3–5 years.
If the shower connection is selected, the set does not include a brass valve, because the shower faucet serves as the valve and no additional element is needed.

The system is prepared for installation and supplied with a complete set of components needed for connection. This makes it easier to start the filter quickly and later replace the consumable cartridges on your own.
For the reverse osmosis system to operate stably and ensure high filtration efficiency, the replacement intervals for consumable components must be observed. The WPL2 cartridge and the WWL2 cartridge should be replaced at least every 6 months. The VONTRON 150 GPD membrane has an estimated service life of about 3–5 years.
The efficiency and the ratio of pure water to rejected water are mainly affected by water pressure and temperature. Proper operation, regular replacement of pre-filter cartridges, and maintaining operating parameters within the recommended range help extend the service life of the osmosis membrane.
Capacity up to 570 l/24 h applies to operating conditions at 6 bar pressure and water temperature of 25°C.

Choose a set or individual cartridges. Replacement intervals depend on the cartridge and operating conditions.
Yes. The filter is prepared for installation, assembled, and supplied with a complete set of required components, including the membrane, tubing, drain clamp, brackets, and installation manual.
The system is primarily suitable for freshwater and marine aquatics, where water with very low hardness and conductivity is needed. It can also be used for cosmetic purposes, laboratory applications, and steam irons.
The filter helps reduce conductivity, soften water, and achieve a lower pH. In many cases, the pH decreases by 1–2 points, and the general hardness may drop to zero or close to zero dH, depending on the parameters of the feed water.
The WPL2 cartridge and the WWL2 cartridge should be replaced at least every 6 months. The estimated service life of the VONTRON 150 GPD membrane is about 3–5 years.
Available options are 3/8”, 1/2”, 3/4” for a washing machine or dishwasher, and 1/2” for a shower. If no option is specified, the standard 1/2” connection is selected by default.
Yes, the system is also used in marine aquatics. For this application, expanding the set with a DEMI module is recommended to reduce water conductivity even more effectively.
First, the WPL2 cartridge traps sand, silt, rust, and other solid contaminants. Then, the WWL2 cartridge reduces chlorine, chlorine compounds, and organic impurities. The final stage is the VONTRON 150 osmosis membrane, which removes most dissolved compounds as well as bacteria and viruses.
The system capacity and the ratio of pure water to rejected water mainly depend on water pressure and temperature. The declared capacity of up to 570 l/day applies to operation at 6 bar and 25°C, and the pure water to rejected water ratio ranges from 1:2 to 1:6, averaging around 1:3.
