Perfect for those hot summer days (and nights!), the JML ChillMax Air is your very own personal space air cooler and humidifier.

Unlike fans that just move warm air around your room, or air conditioners that use nasty chemical coolants, the JML air cooler only uses evaporation and water to operate!

Using innovative Hydro-Chill Technology, the JML ChillMax pulls in warm air from the room and filters it through cold water. Then turn it into a fine mist of cold air to cool you down. Featuring a whisper-quiet fan with three speed settings, this cool air is then easily circulated throughout your whole room.

The JML ChillMax Air Personal Space Air Cooler and Humidifier doesn’t use chemicals or toxic coolants. It uses ordinary water to keep you and your family safe. 

The Hydro-Chill, antimicrobial filter is designed to hold water without allowing bacteria and mould to develop and grow. It’s even dishwasher-safe, so you can regularly sterilise it and then use it time after time.

Compact and portable, you can easily set up this air cooler wherever you’d like – from the bedside to the office – and enjoy its cooling and humidifying effect. With just one fill, the ChillMax air can run for up to 10 hours on just one filling! Simply fill with water, plug it into any standard wall socket, and enjoy!

This impressive unit features a super-quiet fan set within a sound-protective casing, and a built-in, soft-lit blue LED light, so you can rest easy in comfort.

    Life saver!

    Bought one over the extremely hot Bank Holiday weekend and went back the next day for 3 more! Extremely pleased with the cooling effect. Gave one to a friend with breathing difficulties and it made a huge difference for her.

    Life saver

    Saw this advertised on tv during the very hot spell. Ordered it straight away as the heat was making me feel very unwell. It was brilliant. Instant relief. It just created a cool personal space and I love it. Bring on the next heat wave.

    Great little cooler

    Staff member was honest inasmuch as saying it is for personal space, not a normal sized room. It worked so well especially through the very hot nights and freezing the filter makes quite a difference. Happy customer

    for a small unit, it really does well. Moist cool air delivered over three speeds. Great for hot\humid days when a fan does not do enough. Also good for nights - keeps you cool so you can sleep comfortably. I purchased two: after trying them out ordered another for my office. Very pleased with it. a mini air-con unit.
