Top features

  • Cools effectively, consumes hardly any power: With an air throughput of 365 m³/h and a power consumption of only 36 W, the air cooler reliably supplies rooms up to 35 m² with fresh, cooled air – for a fraction of the operating costs of an air conditioner.

  • Ready to use immediately – no installation required: Evaporative cooling works entirely without a compressor and without refrigerants. Simply fill the water tank, switch on, done – no installation, no tradesman needed.

  • Suitable for bedrooms: With a maximum of 52 dB, the air cooler operates quieter than a normal conversation – for undisturbed nights in the bedroom, peaceful work in the home office, and restful sleep in the children's room.

  • Protects the respiratory tract: Unlike a traditional air conditioner, evaporative cooling does not dry out the room air but lightly humidifies it – pleasant for irritated mucous membranes and especially appreciated by allergy sufferers.

  • Control by voice: Full compatibility with Amazon Alexa and Google Home enables convenient voice control and remote operation via the app – anytime and from anywhere.

Product description

36 W, no installer, no refrigerants – yet pleasant coolness throughout the room: the Klarstein air cooler puts an end to sweaty summer nights without the need for an expensive air conditioner.

Thanks to evaporative cooling, the device operates entirely without a compressor and refrigerants. The 365 m³/h powerful airflow distributes cooled air evenly over up to 35 m² – and at a maximum of 52 dB. So quiet that you can run it in the bedroom or children’s room without disturbing sleep. Another advantage over traditional air conditioning: evaporative cooling does not dry out the room air but lightly humidifies it – good for irritated mucous membranes, good for allergy sufferers.

The robust ABS housing with all-round ventilation slots ensures even air distribution. The adjustable louvers can be precisely aligned, and the 180° oscillation spreads the coolness widely throughout the room. The 4-litre water tank is easy to remove and clean – hygiene is no issue. Two reusable cooling packs are included and enhance the cooling effect when needed. Control is via the front panel, remote control, or voice via Amazon Alexa and Google Home.

Whether in the home office, on the terrace, in the living room, or in the children’s room – the handle makes it quick and easy to move the air cooler. Cafés, boutiques, and small offices appreciate it as a straightforward solution for hot days. With only 36 W, it consumes a fraction of the energy of a conventional air conditioner – up to ten times less power in direct comparison.

Get cool air without installation effort – order today and start tomorrow.

J'ai acheté ce rafraîchisseur il y a 3 semaines et j'en était satisfaite étant donné le prix que je l'ai payé. Mais là, déception, il fuit. Tous les numéros de tél indiqués pour contacter le service client Klarstein ne sont plus attribués et je n'ai trouvé aucun formulaire de contact sur le site pour être mise en relation avec la marque et signaler le problème rencontré. C'est très décevant et j'ai un peu l'impression d'avoir fait le mauvais choix. Donc service client, à revoir car inexistant !

Bilan après 3 heures d’utilisation avec de l’eau glacée dans un espace d’une trentaine de m2 avec 30 degrés intérieur et 35 extérieur, en ventilation maxi.
Au mieux, on peut gagner quelques dixièmes de degrés et au pire la température intérieure est stabilisée malgré l’élévation de l’extérieure, avec un taux d’humidité qui passe de 55% à 63%.
Comme dit partout à propos des rafraîchisseurs d’air, il ne faut pas espérer de miracle,
Cependant l’appareil fait un job honnête de ventilation avec un volume sonore raisonnable, je n’attendais pas vraiment plus. Il est de plus commandable depuis une appli compatible Tuya/SmartLife, c’est sympa..
En résumé : ventilation assez puissante, fonction rafraîchissement qui permet de contenir la température intérieure (mais pas vraiment de l’abaisser), pilotage par application, ça vaut 4 étoiles.
