Aquaphor RO-101S reverse osmosis system

Powerful yet compact reverse osmosis system with the innovative storage tank. RO-101s is one the most efficient and versatile domestic RO systems in the world given its high performance, water efficiency and incredible economic feasibility.

The system represents all the processes performed on a drinking water plant, providing you with tasty and absolutely safe, soft and odorless water no matter what the initial supply is. Requires one-third of the space under the sink usually assigned to classic RO systems.

Main features of Aquaphor RO-101s:
- Compact and ergonomic design
- 5 liters of fresh drinking water stored in the tank
- High water efficiency and increased speed of purification
- Operates at low tap pressure without electric pump
- Optimizes Calcium and Magnesium concentration, depending on the initial water hardness
- Reduced drainage water loss as compared to the classic ROs
Healthy minerals
Mg2+, Ca2+
No limescale
Fresh tasty water
Filtration speed
190 L/day (50 gallons per day)

Compact efficiency

The unique water-on-water storage tank design saves your time and budget! Compared to traditional RO systems with an air-on-water tank, RO-101S lets the filtration rate remain constantly high while staying compact, water-efficient and undemanding to water pressure from the mains.

Reasons to love having a reverse osmosis system

Maximum safety for drinking water
Reverse osmosis (RO) purifiers reject even the tiniest amounts of impurities in tap water making it safe to drink and cook with. In addition to common contaminants, RO systems remove fluoride, cysts, bacteria, viruses, antibiotics and hormones. The best choice for someone with a sensitive health.
Reduces hardness and limescale
Coffee makers, electric kettles, and all kind of kitchen appliances suffer from scale build-ups and film in hard water. Reverse osmosis is the most effective method to deal with scale build-up and chalky off-taste.
Improves the taste of food and drinks
Removes the off-tastes of chlorine and chalk in water making every meal and drink more delicious. This system makes water ideal for cooking.
Quick access to fresh drinking water
The RO system collects fresh drinking water for future use, filling up the storage tank within 15- 60 minutes depending on tap pressure, water mineralisation and temperature.

How it works

With the Aquaphor Morion 101S water undergoes all the same stages as on the water plant, including preliminary purification stage, membrane separation and final conditioning with remineralization.
No special maintenance is required for the filters change.
The prefiltration block should be replaced every 6 months, membrane filter - every 1.5 years.
With Click&Turn technology even a child can replace filters with no risk of contacting the filtered matter.

What it filters

Fully removes: all possible allergens such as chlorine, pollen, sediment, heavy metals including lead, copper, mercury, arsenic, organic compounds, remains of drugs including antibiotics and hormones, pesticides, phenols, microbial and organic contamination.
Water minerals: reduces excessive water hardness, provides perfectly clean and soft drinking water with the beneficial mineral balance of Magnesium and Calcium.

*not all contaminants may be present in your water

If you haven't used the water purifier for more than a week, let the water run, empty the storage tank and let it get filled in again. Use freshly filtered water, long-term storage is not recommended.
The frequency at which the filter and membrane cartridges should be replaced depends on the quality of the water that enters the appliance. Contact your water treatment specialist for replacement filters.

The installation of the RO-101 appliance on pre-treated water supply will greatly increase
the life of its filters. To find out more about pre-filters check the catalog.
