Models of the De'Longhi Clessidra class represent an advanced mid-range drip coffee maker for domestic purposes. The brewing of an invigorating drink in them occurs without forcing excess pressure. Devices of this type are also called filter coffee makers, since they use replaceable paper filters with ground coffee to make black coffee. The aroma, taste and tonic power of such coffee depends on the type of beans, the degree of their grinding and the amount of water passed.

The glass flask for water in the models of the series has a volume of 1.2 liters, which is enough to prepare up to 10 servings of fragrant Americano. During operation, the water heats up to 90-94 °C and then slowly “drips” through the layer of ground coffee in a disposable filter. At the same time, Clessidra coffee makers are able to keep the drink hot for a long time thanks to the function of heating the glass coffee pot stand, which can be useful in an office environment.

Simple and inexpensive "workhorses" from the portfolio of the Italian brand De'Longhi for quick preparation of americano from ground coffee. They belong to the class of filter coffee makers.

In the devices of the series, a “drop-stop” leakage protection system is implemented, a mechanism for auto-shutdown of coffee makers in case of overheating is provided. Nothing superfluous like a timer is supposed to be here, just as there is no information screen. Models of the De'Longhi Clessidra squad are definitely worth the money - in the mid-low-cost echelon of filtration coffee makers without all the frills, they need to look for equals.
