Top features

  • Cools a room without running up your energy bill: Using evaporative technology, the Skytower delivers an airflow rate of 280 m³/h across rooms up to 25 m² — while consuming just 60 W of electricity. That's up to ten times less power than a conventional air conditioning unit.

  • Four jobs, one appliance: The Skytower combines air cooling, fan circulation, air humidification, and air purification in a single tower unit — so you get a genuinely comfortable room environment without needing four separate devices cluttering up the place.

  • Whisper-quiet overnight: At a maximum of 55 dB, the Skytower runs well below the threshold that disturbs sleep — and with Sleep mode reducing fan speed gradually through the night, you won't even notice it's on by the time you drift off.

  • Ready straight out of the box: No installation, no engineer, no waiting. The Skytower uses evaporative cooling — no refrigerant, no compressor — so you simply fill the tank, plug it in, and start cooling. Four castors let you move it from room to room in seconds.

  • Control it without getting off the sofa: Fully compatible with Amazon Alexa and Google Home, the Skytower responds to voice commands so you can adjust the fan speed, change the mode, or set the timer from anywhere in the house — or use the dedicated app when you prefer.

Product description

When summer arrives and your bedroom turns into a furnace, you don't need a full air conditioning system — you need the Klarstein Skytower. This evaporative air cooler delivers a steady breeze to rooms up to 25 m², using just 60 W of power and zero installation. Plug it in, switch it on, and feel the difference within minutes.

The Skytower works through evaporative cooling: water evaporates across the humidifier pad and the outgoing air drops in temperature — no refrigerant, no compressor, no noise. The 6-litre water tank keeps it running for hours between refills, and the maximum 55 dB operating volume means it won't disturb a light sleeper. That's quieter than a normal conversation.

The tower design does more than look smart in a corner. A 60 cm air outlet distributes fresh air across the room, while adjustable louvres let you direct airflow exactly where you want it. Switch on the 180° horizontal oscillation and cooled air reaches every part of the room evenly. Control it from the top-panel display, the included remote, or via the Klarstein app — and if your hands are full, just ask Amazon Alexa or Google Home to handle it.

Unlike a conventional air conditioner, the Skytower adds moisture to the air rather than stripping it out. That's genuinely useful in centrally heated or dry environments — your throat, skin, and sinuses will thank you. The integrated ioniser also removes dust and fine particles from the air as it circulates, making it a practical choice for allergy sufferers. Four castors mean you can roll it from the home office to the living room to the bedroom without effort.

In short: 4-in-1 functionality (air cooler, fan, humidifier, air purifier), a long-running 6-litre tank, smart home compatibility, up to 61 dB maximum noise, and running costs a fraction of a traditional air con unit. No plumber, no engineer, no fuss.

Stay cool this summer — order the Klarstein Skytower and get on with enjoying the warm weather.

Le produit est vraiment bien et fonctionne parfaitement. Seul petit bémol : impossible d’enlever la pompe à eau pour retirer complètement le réservoir. J’ai suivi les indications de la notice à la lettre, mais rien à faire, ça ne se démonte pas. Dommage, car ça aurait rendu l’entretien encore plus pratique.

The product is really good and works perfectly. The only small downside: it is impossible to remove the water pump to completely remove the tank. I followed the instructions in the instructions to the letter, but nothing to do, it does not disassemble. Too bad, because it would have made maintenance even more practical. _______________________________ ================================== REPLY ================================== Dear customer, We sincerely thank you for taking the time to share your experience with our product.

Ein Luftkühler kann kaum besser sein! Eine Bekannte, die Leiterin einer Reha-Klinik ist, hat gleich mehrere Luftkühler für die Klinik bestellt, als sie den Luftkühler bei mir gesehen hat :-)

Positiv: unproblematischer Aufbau, Wifi Verbindung über die Klarstein App und gute Luftreinigung. Als schnelle Lösung für trockene Luft perfekt. Negativ: - keine Anzeige der Temperatur oder Luftfeuchtigkeit ( hab mir zusätzlich einen Wifi Thermometer / Luftfeuchtigkeitsmesser bei Amazon gekauft, um überhaupt zu wissen ob die Luft Feuchtigkeit braucht) - Pumpe für für Luftfeuchtigkeit gluckert - Von der Kühlung mit Eispads merke ich nichts und ist auch nicht messbar - Lautstärke des Lüfters bei Schlafmodus und Normal Modus ist identisch Insgesamt bin ich gut zufrieden, da ich einen Luftreiniger und Luftbefeuchter haben wollte - wer sich eine deutliche Abkühlung erhofft - ich kann keine feststellen

Positive: Easy setup, Wi-Fi connection via the Klarstein app, and effective air purification. Perfect as a quick solution for dry air. Negative: - No temperature or humidity display (I also bought a Wi-Fi thermometer/humidity meter from Amazon to know if the air needs humidity) - Humidity pump gurgles - I don't notice any cooling effect from ice pads, and it's also not measurable - Fan noise is identical in sleep and normal mode. Overall, I'm quite satisfied, as I wanted an air purifier and humidifier. For those hoping for significant cooling, I haven't noticed any.

Ich verwende schon seit fast sechs Jahre Luftkühler mit Wasserkühlung, der neue den ich mir geholt habe übertrifft alle anderen! Und ich bin zufrieden mit der Leistung außer dass er zu viel Wasser verbraucht

I've been using water-cooled air coolers for almost six years, and the new one I got outperforms all the others! And I'm happy with its performance, except for the fact that it uses too much water.

Tenemos el climatizador en una habitación orientada al Sur, muy calurosa. Usando los dos depósitos de gel congelados y vertiendo dos botellas de agua de 1,5 l. el equipo logra reducir la temperatura de forma sostenida entre 2 y 3º. En el nivel 3 hace bastante ruido, pero el 2 es muy aceptable. Después de un mes de uso diario, soportando una ola de calor tras otra, el resultado es muy satisfactorio. Además, su diseño es muy elegante (para ser un ventilador - climatizador)

We have the air conditioner in a very hot, south-facing room. Using the two frozen gel containers and pouring two 1.5-liter bottles of water, the unit manages to steadily reduce the temperature by between 2 and 3 degrees Celsius. On level 3, it's quite noisy, but level 2 is very acceptable. After a month of daily use, enduring heat wave after heat wave, the results are very satisfactory. Furthermore, its design is very elegant (for a fan-air conditioner).

La mia scelta è caduta su questo modello di raffrescatore evaporativo principalmente per la sua compattezza e per il basso consumo di energia elettrica necessaria al suo funzionamento essendo la potenza assorbita di soli 60 watt; particolare non di scarsa importanza considerato atteso l’attuale elevato innalzamento dei costi di questa fonte energetica. Ho inoltre apprezzato la possibilità di poter utilizzare l’apparecchio solo come ventilatore con tre diversi livelli di potenza che assicurano il raffrescamento dell’ambiente in maniera uniforme grazie alla possibilità di oscillazione delle lamelle direzionali del flusso d’aria, prodotto dal dispositivo, sia in senso verticale che orizzontale. La modalità di funzionamento prescelta viene indicata su un ampio display e tutte le funzioni dell’apparecchio sono gestibili da remoto a mezzo del telecomando fornito in dotazione; è inoltre possibile la connessione del dispositivo alla rete WIFI di casa in modo da poter attivare le modalità di funzionamento anche attraverso lo smartphone previa la semplice installazione di un’apposita applicazione. Il raffrescatore è facilmente trasportabile grazie alle quattro rotelle piroettanti poste, a scomparsa, nella base dello stesso. Considerate le molteplici prestazioni offerte mi ritengo soddisfatto dell’acquisto anche per il buon rapporto qualità/prezzo.

I chose this evaporative cooler model primarily for its compactness and low energy consumption, with a power consumption of just 60 watts; this is a significant advantage given the current soaring costs of this energy source. I also appreciated the option of using the unit as a fan only, with three different power levels that ensure uniform cooling of the room thanks to the oscillation of the slats that direct the airflow produced by the device, both vertically and horizontally. The selected operating mode is shown on a large display, and all the device's functions can be managed remotely using the included remote control. The device can also be connected to your home Wi-Fi network, allowing you to activate the operating modes even via your smartphone by simply installing a dedicated app. The cooler is easily transportable thanks to the four retractable casters located in its base. Considering the many features offered, I am satisfied with the purchase also because of the good quality/price ratio.

Me encanta el diseño,ocupa muy poco. Necesitaba algo pequeño para un dormitorio. Se sincroniza con la app klarstein por wifi,es muy muy fácil, sólo tuve que pulsar unos segundos en el botón del wifi del enfriador y desde la app busqué el modelo y sincronizado. Se puede activar y desactivar,elegir el modo, programar rutina... Tiene 3 velocidades de ventilador (baja (1),media(2),alta(3)). Cuanta más velocidad, obviamente más aire y más ruido ya que las aspas se tienen que mover más para proporcionar la ventilación indicada pero no es un ruido molesto. Además del wifi me ha gustado que tiene dos rejillas de dirección de la ventilacion,una interna que se mueve de izquierda a derecha y la exterior que es de arriba a abajo. Ambas son independientes puedes poner una fija y la otra móvil,las dos fijas o las dos móviles. El tanque de agua es fácil extraerlo, tiene además dos placas para congelar. Además de la app y los propios botones del aparato,lleva un mando el cual se puede guardar en el propio enfriador. En cuanto a si ’’tira’’aire frío, sí. Hay que tener en cuenta que es un enfriador y no un aire acondicionado, el aire lo coge del tanque de agua+placas congeladas. Tira un aire muy agradable,nada molesto. Yo estoy usando la opción de purificador hasta que llegue el verano. Lleva el modo noche por si lo usas para dormir que no haga ruido. Quizás pueda parecer costoso,pero es de tremenda calidad y son 3 en uno.

I love the design; it takes up very little space. I needed something small for a bedroom. It syncs with the Klarstein app via Wi-Fi; it's very, very easy. I only had to press the Wi-Fi button on the cooler for a few seconds, then search for the model from the app and it synced. You can turn it on and off, choose the mode, program a routine, and so on. It has three fan speeds (low (1), medium (2), high (3)). The higher the speed, the more air and the more noise, obviously, since the blades have to move more to provide the desired ventilation, but it's not a bothersome noise. In addition to the Wi-Fi, I liked that it has two ventilation directional grilles: an internal one that moves from left to right and an external one that moves from top to bottom. Both are independent; you can set one fixed and the other to move, both fixed or both moveable. The water tank is easy to remove, and it also has two freezing plates. In addition to the app and the buttons on the device itself, it has a remote control that can be stored in the cooler itself. As for whether it "blows" cold air, yes. Keep in mind that this is a cooler, not an air conditioner. It draws air from the water tank and frozen plates. It produces very pleasant, non-disturbing air. I'm using the purifier option until summer arrives. It has a night mode so it doesn't make any noise if you use it to sleep. It may seem expensive, but it's of tremendous quality and it's a three-in-one unit.

Por ahora solo he hecho una pequeña prueba porque aún no está haciendo demasiado calor, o al menos no durante el tiempo suficiente, pero quería dejar mi opinión por si les ayuda a quienes estén buscando una alternativa al aire acondicionado o a los típicos “Pingüinos” y quieran adelantarse a la temporada alta como yo. Elegi este aparato porque tengo varias cosas de la marca y estoy contenta con ellas. Me gusta mucho que se pueda controlar desde la aplicación del móvil. Funciona fenomenal y da opciones de programación de encendido y apagado o incluso de temporizador que son mucho más cómodas de configurar desde la App. En la descripción pone que emite un ruido de 60dB y me preocupaba que fuera demasiado, pero es lo normal en este tipo de aparatos y he podido comprobar que con el ventilador al mínimo y a unos 2m de distancia, el ruido es de 40dB. Se me queda un poco corto el cable, no lo tuve en cuenta, pero es fácil de resolver con un alargador. De momento encaja perfectamente con lo que esperaba, cuando venga el calor y pueda probar la función de frío de verdad, trataré de actualizar la reseña poniendo información al respecto. Me gusta la sensación que da la función de viento “natural” que va alternando la intensidad del ventilador para dar una sensación de ráfagas de viento, sin embargo los cambios en el ruido al variar la intensidad pueden resultar molestos si estoy escuchando música o la tele. Para leer esta genial, es muy agradable.

For now, I've only done a small test because it's not too hot yet, or at least not for long enough, but I wanted to leave my opinion in case it helps those looking for an alternative to air conditioning or the typical "Penguins" and want to get ahead of the peak season like me. I chose this device because I have several of the brand's products and I'm happy with them. I really like that it can be controlled from the mobile app. It works great and offers on/off scheduling options or even a timer, which are much more convenient to configure from the app. The description says it emits a noise of 60 dB, and I was worried it might be too much, but that's normal for this type of device. I was able to verify that with the fan on minimum and about 2 meters away, the noise is 40 dB. The cable is a bit short for me, so I didn't take that into account, but it's easy to solve with an extension cord. For now, it's perfectly suited to what I expected. When the warmer weather arrives and I can actually test the cooling function, I'll try to update the review with more information about it. I like the sensation of the "natural" wind function, which alternates the fan's intensity to create a gusty wind sensation. However, the changes in noise when changing the intensity can be annoying if I'm listening to music or watching TV. It's great for reading; it's very pleasant.
