Chillmax Air Go - Portable, take-anywhere personal cooler

Product Information

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! 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. 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 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. 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.

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.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 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

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.

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! Cools and humidifies 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. 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. 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!

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! As an example, if the air temperature is 30ºC and 50%RH, it will feel like 31ºC, but if the humidity goes up to 80%RH, then it will feel like 38ºC – even though the thermometer still tells you it’s 30ºC. Evaporative coolers are a big risk with the humidity we experience in the UK. And especially indoors. 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! Adjustable three-speed whisper-quiet fanJML 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. 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. They cool the inlet air by several degrees. But they send the humidity of that air up considerably, and this cancels out the benefits of the cooling effect when it is very hot. The ‘Heat Index’ is the key detail, as explained above. In the case of the InstaChill, it will add a lot more humidity than the ChillMax, and as I have explained and demonstrated, the ChillMax is bad enough when it comes to increasing the ‘feels like’ temperature.
