Wholesale Ecosoft P’URE AquaCalcium reverse osmosis filter

With mineralization filter

Reverse osmosis is the most effective technology of drinking water purification. It reduces 99.8% of impurities, as well as odors, flavors, and viruses making water clear, clean, tasty, and safe for human health, both adults and children. Along with that, the reverse osmosis filter is one of the most cost-effective methods of domestic water purification.

Advantages of the Ecosoft P’URE AquaCalcium reverse osmosis filter

  • World leader DOW Filmtec™ membrane (USA)

  • 6 stages of water purification including mineralization

  • 280 L of drinking water per day

  • Up to 7 L storage tank

  • Water enriched with calcium in the AquaCalcium filter

  • Both vertical and horizontal mounting possible

  • ‘Clean room’ effect — vacuum tightness of the filter since it leaves its assembly line

Benefits of using the filter

  • Source of absolutely clean and safe drinking water

  • Dishes cooked with the water will taste better

  • Coffee beans and tea leaves will open up their flavors and aroma

  • With the water, you will get the important mineral element calcium

After the Ecosoft P’URE AquaCalcium reverse osmosis filter, the drinking water is enriched with calcium. That is why it is especially recommended for:

  • children and teenagers

  • elderly people

Calcium reduces risk of osteoporosis, hypertension, brain attacks, obesity and many other diseases.

Components of the filter

  1. Filtration module

  2. Metal storage tank (general vol. 11 L, effective vol. up to 7 L)

  3. Stylish faucet ‘Modern’ for purified water

  4. Included feed water adaptor with feed valve for connection with water mains

  5. Ball valve faucet of storage tank

  6. Set of color tubes (4 pc.) for convenient filter installation

  7. Drain saddle clip for connection of the filter to sewers

  8. Set of replacement pre-filters (improved)

  9. DOW Filmtec™ membrane 75 GPD (280 L per day)

  10. Service wrenches for replacement of filters and the membrane

  11. Instruction manual

Stages of water purification

The feed water flows through the three pre-filters intended to reduce sediments (rust, sand, silt etc.), chlorine and chlorination by-products, as well as organic matter.

The fourth stage is represented by the reverse osmosis membrane which at the molecular level purifies the water from 99.8% impurities including bacteria and viruses.

The water purified by the reverse osmosis membrane flows through the AquaCalcium replacement filter where the 1st stage of mineralization takes place. Special technology of the filter reproduces natural speed of water flowing through mountain rocks. The time of its contact with the composition of the AquaCalcium replacement filter increases, and consequently permanent content of minerals in the purified water is provided.

Then the purified water is supplied to the storage tank. From the tank, the water undergoes the 2nd stage of mineralization in the AquaCalcium replacement filter.

Then it flows to the carbon post-filter intended for the final water purification. It contains high-quality activated coconut shell carbon which improves purified water taste and odor, and adds slight sophisticated sweetish flavor.

* If pressure in the water supply system is lower than indicated, the filter should be supplied with a pump. If pressure in the water supply system is higher than indicated, it is necessary to install a pressure regulator at the inlet before the reverse osmosis filter.

** If pressure is lower or higher than indicated, it is necessary to pump up or release the pressure.

*** If the temperature of feed water is within the range +20…+30 °C, selectiveness of the membrane insignificantly decreases, and capacity increases leading to insignificant growth of the TDS indicator. Application of the filter when the temperature of feed water exceeds +30 °C is not recommended.

The reverse osmosis filter is intended for treatment of cold water only.

If time needed to fill the storage tank has increased, it means that the pre-filters are exhausted, and it is necessary to urgently replace them. Delay with the replacement might damage or destroy the membrane. To avoid such critical situations, we strongly recommend to replace the set of pre-filters at least once in 3 months.     

If speed of filtration is decreasing significantly, it is necessary to replace the reverse osmosis membrane. We recommend to replace the membrane at least once a year.

In case there are long breaks (exceeding 2 weeks) in filter application, it is necessary to disinfect the filter (see detailed description of the procedure in the manual). When you are not planning to use the filter during a long period of time, it is recommended to turn off water supply to the filter.

* If the feed water condition does not correspond to the indicated requirements, service life of the membrane and replacement filters might decrease.

** In case of application of the filter for borehole or well water, it is recommended to make a preliminary chemical analysis of the water. If certain indicators exceed the values in the table, it is recommended to install additional filters before the reverse osmosis filter.
