With the Waterdrop Filter C1H, the manufacturer presents a table-top reverse osmosis system that produces hot water at the touch of a button. Within a few seconds, fresh tap water is not only thoroughly filtered, but also heated directly. This makes the system suitable for both water treatment and the preparation of tea, coffee and other hot drinks. Thanks to the integrated filter, any harmful substances such as chlorine, fluoride, PFOA/PFOS or other heavy metals are also significantly reduced. Operation is also convenient, as the Waterdrop Filter C1H is equipped with a touch display. This can be used to conveniently control both the amount of water and the desired temperature.
Today’s test will clarify whether the Waterdrop Filter C1H is worth buying and who is likely to benefit most from it.

Scope of delivery
- One filter already included in the scope of delivery
- Quick assembly of the water filter system
As far as the scope of delivery is concerned, the Waterdrop C1H is not supplied pre-assembled. Accordingly, the drip tray and the filter are stored separately in the package. The scope of delivery is supplemented by the usual pile of paper documents, including the instructions for use and an information card with customer service details.
Appearance & finish
- Sleek, minimalist design with compact dimensions
- Sophisticated design with front removal and rear raw water tank
- Robust materials with magnetic drip tray
Visually, the Waterdrop Filter C1H has a slim, minimalist housing with clear contours and a matt finish. This allows the Waterdrop Filter C1H to blend unobtrusively into modern kitchens, offices or even smaller residential units. Another advantage is its compact dimensions of around 30 cm in length and 21 cm in width, which means it should even fit into narrower shelves. The front of the Waterdrop Filter C1H is a mix of black and gray tones. The display on the top is completely black, right down to the indentation of the drip tray. The front also serves as the extraction point for the filtered water, while the 3.2 liter removable raw water tank is located behind the machine. In contrast, the top of the C1H is in two parts: one part of the lid serves as access to the filter and the carafe, while the other part is used to seal the raw water tank.
The workmanship and choice of materials score points. The plastic components feel robust and even the touch display has a pleasant feel. As the drip tray has a magnet on one side, all you have to do is attach it to the front of the C1H. It then stays in position automatically and can be easily removed for cleaning, making it easier to use. The same principle applies to the two lids, which can be easily removed to cleverly conceal the inner workings. What’s more, the pull-out handle for the raw water tank makes it easy to transport for refilling at the tap.
Equipment
- Six-stage reverse osmosis with efficient 3:1 water ratio
- Filter change should be carried out every 12 months
- Minimalist touch display without display of TDS values
In terms of features, the Waterdrop Filter C1H cuts a fine figure. At its heart is the integrated reverse osmosis filtration (RO technology), one of the most effective processes for drinking water treatment. The C1H also uses a six-stage filter system, which achieves a water-to-wastewater ratio of 3:1. Waterdrop Filter specifies a maximum service life of 12 months for the replaceable filter before it should be replaced for purely hygienic reasons. The exact replacement time naturally depends on personal use and the local water quality. If such a replacement is due, the built-in display will inform you in good time.
The touchscreen display on the front has a deliberately minimalist design, giving it a very tidy appearance. It only shows the current amount of water in milliliters and the selected water temperature. Two buttons below this are used to control the fill quantity and temperature. If you find the preset levels too coarse, you can use the favorites mode. The latter allows the filling quantity to be set individually in 50 ml increments and the temperature to be set at 5 °C intervals. However, there is no display of values such as Source-TDS or Pure-TDS, making it almost impossible to monitor the water quality precisely.
Practical test
- Simple operation with fast water and hot water preparation
- Useful child safety lock, but somewhat cumbersome in everyday use
- Good water filtration with a neutral taste
The Waterdrop Filter C1H proves to be an easy-to-use water filter system in everyday use. Initial commissioning only requires the insertion of a new filter and subsequent rinsing, which takes a little more time as this involves filtering through twice the volume of the raw water tank. The machine is then ready for use as usual.
Everyday experience
In everyday use, the fast water supply via the front outlet is impressive. At ambient temperature, the water comes out immediately and using the hot water function it only takes around three seconds – with virtually no delay. By comparison, a conventional kettle takes considerably longer. The power-saving function of the display is particularly practical. It switches off completely when not in use and can be reactivated simply by tapping the screen again.
Childproofing & handling with a carafe
The automatically activated childproof lock when drawing hot water is basically cleverly designed, but proves to be rather cumbersome in practice. When the water temperature is increased – for example from the ambient temperature to 45 °C – a red warning symbol appears, which blocks the water from being drawn. The hot water can only be dispensed after tapping the symbol. Although the function provides additional protection, a manual on/off option for the child safety lock would have been much more intuitive in everyday use.
Another positive feature is the one-liter carafe, which fills automatically when inserted into the Waterdrop Filter C1H. However, a second carafe in the scope of delivery would be desirable. This would allow you to use one carafe that is already full while the other is being refilled at the same time. In the current version, you always have to wait a short time when reinserting the carafe until the Waterdrop Filter C1H has finished filtering and refilling. Please note: As long as there is no carafe in the housing, no water can be removed.
And how is the taste?
The taste of the filtered water from the Waterdrop Filter C1H is quite neutral by German standards, with a tendency towards blandness. Of course, it should be noted that German tap water is already of high quality and can be consumed straight from the tap. People in many other countries do not have this privilege, which in turn underlines the necessity and importance of such a water filter system.
Conclusion
The bottom line is that the Waterdrop Filter C1H is well worth considering as a water treatment system. The multi-stage RO filtration produces noticeably pure, tasteless water. Added to this is the fast preparation including hot water function, while the preset temperatures and quantities make it easy to use. In this respect, the Waterdrop Filter C1H is not only suitable for the home kitchen, but also for the office or on the road in a mobile home.
However, we see room for improvement in the comparatively cumbersome child safety lock, which is automatically activated when the machine is restarted and cannot be switched off completely. An additional 1-liter carafe would also be useful so that you always have a carafe on the go and can refill the other one in the Waterdrop Filter C1H.
The Waterdrop Filter C1H could therefore be of interest to anyone who is currently leaning towards an installation reverse osmosis system but only has a limited budget. Experience has shown that standard professional reverse osmosis systems cost several hundred euros more.
