Cools the room without air con: Using evaporative cooling, the Mistral pushes 360 m³/h of cooled air through rooms up to 35 m² — no refrigerant, no compressor, and a fraction of the running costs of a conventional air conditioning unit.
Everything your room needs, in one place: Air cooler, fan, humidifier, air purifier, and ioniser — all built into a single unit, so you get a complete room climate without cluttering the place with separate devices.
Quiet enough for a good night's sleep: With a minimum noise level of 40 dB(A) and a dedicated Sleep mode that gradually winds down before switching off automatically, the Mistral won't disturb your rest.
Kinder to your airways than standard air con: The built-in humidifier adds up to 600 ml of moisture per hour to the room air, countering the dry, stale conditions that can aggravate allergies or irritate sensitive sinuses — something a standard fan simply can't do.
Ready to use anywhere in the house: No installation, no tools — just plug it in and it works. The compact design makes it easy to move between rooms, and the included remote means you stay in control without getting up.
Product description
Summer in the UK might not last long, but when the heat hits, it hits hard. The Klarstein Mistral is an evaporative air cooler that does the job of five separate appliances — cooling, fanning, humidifying, purifying, and ionising the air — all from one compact unit you simply plug in and use, no installation required.
Evaporative cooling works by passing air over water, which lowers the temperature of the airflow naturally — no refrigerant, no compressor, and up to 10× less energy than a conventional air conditioning unit. With a 360 m³/h airflow, the Mistral cools rooms up to 35 m² effectively, making it well suited to living rooms, bedrooms, home offices, and children's rooms alike.
The 4-litre water tank is removable and easy to clean, keeping things hygienic without any fuss. Adjustable louvres let you direct the airflow exactly where you need it, and the 80° left/right oscillation distributes cool air evenly around the room. You can control everything from the front panel or the included remote — useful when you'd rather not get up from the sofa.
One of the Mistral's less obvious benefits is what it does for your air quality. The built-in ioniser filters out dust and odour particles, while the humidifier adds up to 600 ml of moisture per hour — preventing the dry, scratchy feeling that standard air con can cause. If you suffer from allergies or sensitive airways, that difference is noticeable from the first use.
Three fan speeds (high, medium, low) and three operating modes — Normal, Nature, and Sleep — let you tailor the airflow to the moment. The Nature mode varies wind speed for a more natural feel; the Sleep mode gradually reduces the fan speed before switching off automatically. A built-in timer can be set in one-hour increments from 1 to 7 hours, so you're not wasting energy overnight. Operating noise runs between 42 dB(A) and 60 dB(A) — quiet enough to use while you sleep.
Stay cool this summer with the Klarstein Mistral — order yours today and have it ready before the next heatwave arrives.
