Read our review
We tested this device and we’re using it ourselves at home right now. We have to say it’s a great water purifier, especially for those who don’t have space under the sink for a reverse osmosis filter. This device replaces it perfectly, but of course it requires a larger worktop. We didn’t find any bigger downsides, since it can completely replace the kettle with instant water heating.
Water heating in 3 seconds and precise temperature thanks to a smart display
Hydrofast W100 offers up to 8 water temperature options and can heat water in as little as 3 seconds. Whether you want to prepare delicate green tea, instant porridge, or coffee, you can set the ideal temperature easily via the color touch display. There are also 3 preset modes and up to 15 water volume settings, so you can choose exactly how much water you need. A practical night light ensures comfort even during evening use.
Touch control is complemented by a child lock that prevents accidental starting of hot water. The purifier is therefore safe for the whole family, including kids.
Premium 6-stage filtration with mineral enrichment
At the heart of the system is advanced reverse osmosis with a 0.0001 μm membrane, which removes up to 95% TDS and more than 1000 types of harmful substances. The filter handles heavy metals, chlorine, bacteria, and fluoride. While standard RO filters “drain” the water, Hydrofast W100 goes the other way—it remineralizes the water and balances its pH, creating naturally great-tasting and healthier water.
The filtration system consists of 6 layers: PP / CTO / PCF / MIN / RO / UV. In addition to standard filtration, it also provides UV sterilization that eliminates up to 99,99% of bacteria and viruses continuously for 24 hours per day.
Eco-friendly and low-waste
Hydrofast W100 boasts an efficient clean-to-waste water ratio of 3:1, meaning that compared to other RO systems it produces very little waste water. It can filter up to 2000 liters of water with a single set of filters, replacing up to 6000 plastic bottles.
The RO membrane lasts up to 12 months, and the composite filter lasts approximately 9 months. Regular automatic filter regeneration and a simple replacement mechanism via twisting ensure hassle-free maintenance. There’s also a smart reminder for when you need to replace the filters.
No installation required and ideal for any room
A big advantage is the “plug & play” installation. Just plug it in and you can use it anywhere—kitchen, bedroom, or office. It’s ideal for households of 2–3 people, as it features a 4-litre water tank and a daily output of up to 100 GPD (about 380 litres).
A 700 ml cup fills in about 60 seconds. The body is made from BPA-free safe materials and comes with certified components according to the highest food standards.
