A cleaner taste

Good taste does not reveal everything about water quality. Reverse osmosis is a widely used filtration technology for reducing a broad range of dissolved substances.

Use fewer disposable bottles

One W12 filter set treats the equivalent of 2,000–4,000 disposable water bottles.

Water at your chosen temperature

W12 combines water filtration with a hot-water dispenser, providing water at your selected temperature.

25 ° C
Room-temperature water, ready to drink

45 ° C
Warm water setting

55 ° C Intermediate temperature setting

80 ° C Hot water setting for tea

90 ° C
Near-boiling water setting for coffee

100 ° C
Boiling-water setting in seconds, replacing a separate kettle

Long-lasting filters and simple maintenance

Replace filters every 6–12 months or after 2,000 litres of filtered water.

The machine alerts you when the remaining filter resource falls below 20%.

Hard or lower-quality source water may require more frequent attention and earlier replacement of individual filters.

The reverse osmosis cartridge lasts approximately twice as long as the pre-filters and is replaced half as often.

Filter replacement is straightforward and takes moments.

Does the system come with filters?

Yes. The first filter set is already fitted in W12. Fill the tank, plug the unit into a power socket and follow the set-up instructions.

How large is the W12 tank?

The source-water tank holds 2 litres, producing approximately 1 litre of filtered water and 1 litre of reject water. The internal filtered-water tank holds 1 litre.

Filters

Filter elements:

Multi-layer composite filter. Reduces coarse particles such as sand, rust and limescale particles, along with chlorine and organic impurities.
Reverse osmosis membrane.Reduces a broad range of substances. Check the system’s specifications for performance against bacteria, dissolved solids, nitrates, fluoride, metals and other contaminants relevant to your water.
Post-carbon filter. Reduces remaining unwanted tastes and odours for pleasant-tasting water.

Filter disposal:

Where appropriate, separate the filter contents from the plastic housing before recycling. Follow local waste-collection rules.

Questions and answers

Is reverse osmosis water suitable for drinking?

Reverse osmosis reduces minerals as well as other dissolved substances. Minerals also come from food, and some systems include remineralisation. Choose and maintain a system that is appropriate for your water supply and individual requirements.

Does it remove beneficial minerals?

Stayyoung Aqua’s final cartridge contains calcium and magnesium ceramic media, adding approximately 20–30 ppm of minerals back into the water.

Does it remove all fluoride?

No filter removes 100% of fluoride. Stayyoung Aqua’s stated reduction is 85–97% when the incoming level is below 1.5 ppm (mg/L).

Is the filtered water acidic?

Reverse osmosis does not set a fixed pH. Contact with air and dissolved carbon dioxide can affect the measured value after filtration. Remineralisation and the time water is exposed to air also influence the result.

Stomach acid changes the acidity of water after it is swallowed, regardless of its starting pH. Drinking alkaline water does not, by itself, make the whole body alkaline.

Our focus is on water quality rather than a particular pH. Hydrogen enrichment is a separate feature and should not be treated as a promise of medical benefits.
