As I’ve already explained, the Chillmax works by evaporating water on fibrous panels by forcing air across them. That water has got to go somewhere, and in this case it comes out with the cooled air as water vapour. In the right light, you can actually see it – it’s essentially fog, so the cooled air is also moistened. And just like when it’s foggy outside, and everywhere gets damp, this water vapour can condense on cooler surfaces. My data logger collected some and began to drip during the test, and I have since discovered that it also condenses on the front grille and can drip periodically, so you’d need to be careful what you had underneath it if you placed it on a shelf. The fan is quite powerful enough to project the drips forward slightly when they drop. Chillmax Air gives you the best features of both fans and air conditioning in one, compact unit that’s also a night light. Unlike fans that just move warm air around your room, or air conditioning units that cost the earth, make a lot of noise and use ozone-destroying chemical coolants to cool the air but leave it dry, Chillmax Air sprays a fine mist that is then sent through the special filter and so only uses evaporation and water to operate!

JML claims the Chillmax can run for up to 10 hours per fill, but this is likely on the lowest of the three fan speeds, since on top speed it runs out in less than three hours. JML sells the humidification as a positive without relating it to the comfort relationship between temperature and %RH, but note what I said above. If you want to cool down in humid weather, it isn’t just the temperature that needs to come down.

Chillmax Go Fan is a little powerhouse of cooling technology. Designed to hold the maximum power in the smallest space, the clever engineering means you get a powerful, cooling performance with a fan you can hold in your hand. Thanks to the Lithium Ion technology that draws far more power than standard batteries and converts it into a level of energy that lets our smart, compact motor generate so much power you’ll feel like you’re stood in front of a full-sized wall or ceiling fan! Adjustable 360° smart-spin technology The calculation for this is complex (you should see how long my Excel formula for it is). It is non-linear, and the increase in ‘feels like’ is greater at higher temperatures. It also contains an element of opinion/perception, which is why there’s no point using numbers above about 60ºC. But the ‘Heat Index’ is what forecasters use. Incidentally, the official health designations for the colours are: yellow – caution; amber – extreme caution; orange – danger; and red – extreme danger. Vulnerable people need to take these into consideration before going out in hot weather. For the following locations next day delivery may take up to two working days: Aberdeen (AB 30-35, 41-54), Northern Highlands (AB 36-38, 55-56), FK (17-21), HS (1-8), IV (All), KW (0-14), PH (15-32, 34-48), Eire (Republic of Ireland) (EI (ZZ75) (All)), Glasgow (G 83), Guernsey (GY 9), Oban (HS 9, KA 28, PA 20-99, PH 33, 49-99), Isle of Man (IM (All)), Arran (KA 27), Orkney Shetland (KW 15-99, ZE (All)) and Cornwall (TR 21-25).

Early in July 2019, I saw the Chillmax Air advertised on TV in one of those shouty JML ads. That same evening, I was shopping in Asda and saw it on display. I am an idiot for things like this, and bought it on impulse so I could test whether it worked or not. So, the Chillmax definitely cools the air that passes through it. Let’s work on the assumption that it would be able to get the same 4ºC drop no matter what the ambient temperature was. If your room is 38ºC, pulling it down to 34ºC still means it’s bloody hot. And also note that the Chillmax is physically quite small, so the cooling is very localised – it won’t cool an entire room down, and you have to have it less than a metre from your face to feel anything. These are the data for relative humidity recorded at the same time as the temperature measurement, above (the red line is where I moved the logger). The humidity went up dramatically – a jump of about 30%RH.

Someone found this article on the search term “jml chillmax air for pc cooling”. No. Blowing damp air into your PC would be dangerous, potentially expensive, and would only gain you 4ºC at best. Evaporative coolers are a big risk with the humidity we experience in the UK. And especially indoors. There are many, many more. And in every case, the relationship with humidity is the key. If it is already humid, evaporative coolers do not work and actually make things worse.However, this is where the problems come in for the Chillmax and similar devices. If it’s 35ºC and 40%RH, it’ll feel like 37ºC. Cool the air to 31ºC but send the humidity up to 80%RH, and it’ll feel like 41ºC. So it’s actually hotter in terms of comfort. Do the same comparison when the surrounding temperature is 38ºC, and the ‘feels like’ goes from 43ºC to over 50ºC! The special, antimicrobial filter in Chillmax Air is designed to hold water without allowing the bacteria and mould that it contains to develop and grow, it's even dishwasher-safe so you can regularly clean it and use it time after time. The large capacity water reservoir, combined with the filter, means that Chillmax Air holds a lot of water, so you can rely on Chillmax Air to run for up to ten hours, that's a whole night's sleep, or an entire working day in a hot stuffy office, breathing in cool, humid air! Built-in LED mood and night light Until August 2021, the answer in relation to the ChillMax was no. However, I saw an advert (as shouty as usual) for the InstaChill tonight. Unlike the ChillMax, which is the size of a small table top radio, the InstaChill is the size of a bedside cabinet. And you can certainly get larger evaporative coolers from other manufacturers. The working principle is identical, except that the larger the surface area of water, and the greater the airflow over that water, then the greater will be the possible drop in temperature at the front end (and the more moisture being pumped out to increase the humidity). However, cooling effectiveness is influenced greatly by the RH of the air going in. The secret is Hydro-Chill Technology, which uses our advanced evaporative air-cooling filter and our enhanced cool-mist chamber, to pull in warm, dry air and instantly transform it into cool refreshing air! The filter is resistant to mould and mildew and can be put in the dishwasher to clean and sterilise it for years of use. It does cool the air by a few degrees, so in that sense it works. However, it also sends the humidity up, and in most cases that actually makes you feel hotter and more uncomfortable. In that sense, it doesn’t work.

Chillmax Air uses a super-quiet fan set within its sound-protective casing so the noise you hear is minimal, and with three settings you can have the perfect amount of cool, moist air with the least amount of noise. Reusable, antimicrobial filter, runs up to 10 hours per fill No. Evaporative coolers are not influenced significantly by the temperature of the water used in them. The temperature of the air that comes out depends on the temperature (and humidity) of the air going in, and the science of evaporation. Only this evaporation results in the cooling effect observed. Lithium Ion batteries don’t just give you power, they also mean you can recharge and take that power with you. Whether to the office, the bedroom or the beach- even in your hot car for those long road trips. With enough charge to hold for months, and enough power to give you up to six hours of personal cooling, you can rely on Chillmax Go Fan to keep you cool all day, wherever you go! Easy-to-use power dial When the air outside is just as hot and dry as it is inside, you want to take your personal cooling with you. Chillmax Air Go is portable and rechargeable so you can charge up the fan, fill the water tank and away you go! Thanks to the sure-grip clamp you don’t even have to carry it. Just clamp it to your desk, table, the handle of a pram or buggy, take it in the car with you- wherever you want to go, you can have personal cool air at all times! Also has an LED nightlight

The housing of Chillmax Go Fan is cleverly designed around a similar concept to a gimbal or gyroscopic mechanism used in aerospace, aviation and navigation devices. Able to spin on two independent axes, it means you can position your Chillmax Go Fan through 360⁰ in any direction and at any angle for the perfect, multi-directional stream of cool air. Rechargeable lithium ion battery runs for up to 5hours The HUGE difference between Chillmax Air Go and a fan is that a fan simply moves air around so the moving air you get is the same temperature as the room! Why push warm, dry air around when you can cool it down and humidify it first? Like a standard, bulky air-con unit, Chillmax Air Go actually takes the air in your room, or outside, and through evaporation, lowers its temperature. This way you get cooler air, but it’s also been humidified, so no more dry, burning sinuses when you’re trying to sleep. With Chillmax Air Go you’ll get measurably cooler air coming right into your personal space that isn’t dry! Portable design, just charge the fan and take it anywhere At the time of this most recent edit, it is 20 minutes past midnight on 19 July 2022 and the official Met Office temperature in Nottingham (where I am) is between 28ºC and 29ºC (it was just over 37ºC earlier on 18 July). Humidity is 35%RH, but it is up to 60%RH less than 40 miles away at the next Met Office station. In Nottingham, humidity peaked at 60%RH on 18 July, even if it dropped to under 30%RH at times. And that was outdoors – indoors you can add 30-40%RH without blinking.

The ambient humidity in the room where I did the test was about 44%RH. The Chillmax sent that up to over 70%RH. It is this elevation of the humidity of the cooled air which really brings into question whether the Chillmax is worth the investment. Chillmax Air turns cold water, via a special filter, into a finer mist of cool, refreshing air circulated by a fan with three speed settings. It humidifies while it cools your personal breathing space so you can stay cool and breathe moist, humid air wherever you need it. This antimicrobial replacement filter will keep your Chillmax Air running perfectly for months. Designed specially to fit, easily into your Chillmax Air cooler, you can simply swap out the old filter for this new one and you're ready to go! Why not have a spare filter on hand so you always have a clean, working filter in your Chillmax Air and you're never left waiting for the dishwasher on those really hot, dry days and nights? We recommend you replace your filter every three to six months so this replacement filter will last you all Summer! The special, antimicrobial filter in Chillmax Air is designed to hold water without allowing the bacteria and mould that it contains to develop and grow, it’s even dishwasher-safe so you can regularly clean it and use it time after time. The large capacity water reservoir, combined with the filter, means that Chillmax Air holds a lot of water, so you can rely on Chillmax Air to run for up to ten hours, that’s a whole night’s sleep, or an entire working day in a hot stuffy office, breathing in cool, humid air!It might – while you’re blowing air over ice. But once they defrost, which will happen in a few minutes in the temperatures you’ll likely be experiencing, then no. You’ll also have more condensate to deal with from the melted ice pouring out of the front grille. Chillmax Air uses a fan set within its sound-protective casing, and with three settings you can have the perfect amount of cool, moist air for whatever the weather throws at you
