Application
For installation where the cold water pressure is 45psi and above
For under-sink installation for designated purified drinking water. RO water is considered by many to be the best option for drinking water due to its purity, taste, and safety.
OASIS DP is a range of RO units made up with patented and registered DP TRIO filter housings and with RO VESSEL, exclusive reverse osmosis membrane housing with double o-ring & complete with installation kit. All OASIS DP are based on a standard 6 stages unit, made up of: 3 pre-filtration stages, RO membrane stage, G.A.C. activated carbon post-filter stage, re-mineralizer post-filter stage.

This quality system carries the important Watermark certification. Products undergo rigorous testing and assessment by accredited laboratories to ensure they meet the required standards. This includes mechanical testing, chemical testing, and performance testing
Benefits: Enjoy pure, safe water with the re-mineralizing filter. This has many benefits, such as improved taste, essential minerals, pH balance, electrolyte balance, protective coating, and more, which a 4-stage system doesn't offer
Designed in Italy, assembled in Taiwan, with components made in Italy.
Environmentally Friendly
The filter housings, made of PET, a highly recyclable plastic, are manufactured with a proprietary procedure saving up to 60% of energy in injection molding compared with standard plastics. That is one of Atlas Filtri's commitments to comply with the Kyoto Treaty for the reduction of greenhouse gas (CO2) emissions in the atmosphere.

Test Results of Water Quality After RO Membrane
(Remineralization is added after the membrane.) The membrane cannot differentiate between ‘good’ and ‘bad’ substances, so it removes both.
-
pH: 5.5-6.5
Water with a pH of 5.5-6.5 is mildly acidic, which is generally safe for drinking.
Note: The re-mineralizing cartridge is designed to increase pH and reintroduce beneficial minerals like calcium and magnesium back into the water. -
TDS: 5-15 ppm
A Total Dissolved Solids (TDS) measurement of 5-15 parts per million (ppm) is exceptionally low and typically considered excellent for drinking water quality. Water with such a low TDS concentration generally tastes very pure and is often preferred for drinking. It indicates that the water has very few dissolved minerals, salts, and other contaminants, resulting in a clean and refreshing taste. -
Calcium: <2 ppm
A calcium concentration of less than 2 parts per million (ppm) in water is exceptionally low and typically considered excellent. Calcium is one of the minerals commonly found in water, contributing to water hardness. While calcium is essential for human health, excessively high levels of calcium in drinking water can lead to scale buildup in pipes, appliances, and fixtures. Having a calcium concentration of less than 2 ppm indicates very soft water, which is generally preferred for household use because it reduces the likelihood of scale buildup and may also provide a more refreshing taste. However, it's important to note that extremely low levels of calcium may not provide sufficient dietary intake of this essential mineral, so it's essential to consider overall dietary sources of calcium when evaluating water quality.
Note: The re-mineralizing cartridge is designed to reintroduce beneficial minerals like calcium back into the water. -
Magnesium: <1 ppm
A magnesium concentration of less than 1 part per million (ppm) in water is also exceptionally low and generally considered excellent. Similar to calcium, magnesium is a mineral commonly found in water that contributes to water hardness. While magnesium is essential for human health, excessively high levels of magnesium in drinking water can lead to water hardness and potential scale buildup issues. Having a magnesium concentration of less than 1 ppm indicates very soft water, which, as mentioned earlier, is typically preferred for household use due to reduced scale buildup and potentially better taste.
Note: The re-mineralizing cartridge is designed to reintroduce beneficial minerals like magnesium back into the water. -
Sodium + Potassium: <5 ppm
Having a combined concentration of sodium and potassium of less than 5 ppm indicates very low levels of these minerals in water, which is typically considered beneficial for overall health, particularly for those who need to limit their sodium intake. Water with such low concentrations of sodium and potassium is often preferred for drinking and cooking, as it contributes minimal additional sodium or potassium to the diet.
Note: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
*Values are determined under the following conditions: the temperature of supply water is 25 °C (77 °F), supply water quality, and operation conditions correspond to the manufacturer’s requirements.
Stages
-
Stage 1: 5 Micron Sediment Filter
PP Melt Blown Polyspun Sediment Filter.
The filter will remove sediment, rust, and fine particles. This filter is designed to protect the remainder of the system from particles.
Life span: 6 - 12 months.
Max temperature: 45°C (113°F).
-
Stage 2: Granular Activated Carbon Purifier
CTO, Chlorine, Taste, and Odor Reduction.
This cartridge contains granular activated carbon to reduce chlorine (bad tastes, odors), herbicides, pesticides, and traces of heavy metals.
Life span: 6-12 months.
Max temperature: 45°C (113°F).
-
Stage 3: 5 Micron Carbon Block Filter/Purifier
Chlorine, Taste, Odor, and Sediment Reduction.
This is an activated carbon block filter/purifier that will filter sediment, rust, and fine particles. It will also reduce chlorine (bad tastes, odors), herbicides, pesticides, and traces of heavy metals.
Life span: 6-12 months.
Max temperature: 45°C (113°F).
-
Stage 4: Reverse Osmosis Filmtec (Dupont) TW30-1812-Filmtec (Dupont) Membrane The FilmTec Residential Reverse Osmosis (RO) Elements are some of the most reliable and consistent elements manufactured in the industry
Membrane for the main impurity removal.The membrane has pores that are so small that only pure water makes it through to the other side, effectively removing undesirable contaminants like nitrate, fluoride, arsenic, and salt.
Lifespan depends on the level of impurities in water and incoming pressure, but under normal circumstances, the membrane is expected to last 2-4 years. FilmTec Residential Reverse Osmosis (RO) Elements are some of the most reliable
and consistent elements manufactured in the industry
-
Stage 5: Carbon Post Filter
The carbon post filter’s main job is to give the water a final polish and improve the taste of the water after it has passed through the membrane and has been stored in the tank.
Life span: 6-12 months.
Max temperature: 45°C (113°F).
-
Stage 6: Re-Mineralize
A remineralizer is generally used to add beneficial minerals back into water, particularly after a process like reverse osmosis, which can remove most minerals. This can sometimes result in a slight increase in pH, making the water less acidic. However, the main purpose is not to reduce pH but to improve the mineral content and taste of the water.
Life span: 6 months.
Max temperature: 45°C (113°F).
