Liquid Cooling kit Review

With the hotter days on the way, the heat can make even the most basic task unbearable. Just trying to work, cook, exercise or even sleep become a challenge.

Not to mention, long heat exposure also means dehydration, profuse sweating, and a severe dip in everyone’s mood. 

Who wants to deal with droves of irritable, grumpy people on top of a blistering hot day? No one.

No one definitely likes sweating and being uncomfortable because of the adverse temperature of the environment.

An air conditioner sounds like the most obvious solution. However, air conditioners are expensive.

You sure needed an answer checking up this site. keep reading through, we’ll solve your problem.

What is the Water Cooling Kit

Fans don’t change the air temperature, instead making you feel cooler by aiding the evaporation of sweat from your body.

But to really get cool, you need a device that can lower the air temperature, such as the Evapolar Personal Air Cooler. Designed for personal use, this neat box is an evaporative cooler that uses a tank of water to cool the air it blows at you.

Water Cooling Reservoir – Design

Most evaporative coolers are rather large devices that look more like portable air-conditioning units.

The Evapolar Personal Air Cooler is a small cooler, measuring just 174 x 170 x 170mm, which makes it ideal for placing on a desk. It’s rather gorgeous, too, and is available in three colours.

I’m reviewing the neat glossy white model, but there are black and blue options as well.

As this is an evaporative cooler, it has a 750ml water tank that sits on the side. It’s a little fiddly to remove, and the flap on top is a bit flimsy, but after a couple of refills I got the hang of getting the tank in and out smoothly.

Water from this tank is absorbed into the cartridge inside, spreading evenly over the surface of the cooling pads. As the fan at the rear blows warm air over the water, it evaporates, cooling the air and adding humidity to it.

Cartridges last approximately six months before they need to be changed. The water tank will provide three to four hours of cooling, and the cartridge can absorb around 400ml of water; refilling when the cartridge is saturated extends the cooling time by between one to three hours.

Controlling the Evapolar Personal Air Cooler is easy thanks to the bright screen on top, which doubles as a button.

Press and hold this screen in and the cooler turns on or off. Use the dial around the outside, and you can adjust the fan speed.

With 20 speed settings, there’s plenty of scope for it to offer everything between a gentle breeze and a full blast of air.

In its default mode, the display shows the incoming air temperature, which is the ambient temperature of your room. It also displays the outgoing air temperature, which shows you how effectively the unit is working.

Tap the button once and you’ll access the main menu. This lets you adjust the colour of the water reservoir’s light – you can pretty-much match your decor – and the light intensity; or you can turn the light off.

With Night mode, the reservoir light turns off, and the main display dims, so it isn’t distracting. There’s an option to shine a specific colour when the cartridge runs dry, too, so you know it’s time to refill the water.

It’s a shame that there’s no onboard warning to notify when it’s time to replace the cartridge; the only way to tell is when cooling performance drops, with the Personal Air Cooler becoming less effective.

Who Benefits from Cooling kit?

Heat does not discriminate against anyone. As such, anyone and everyone can benefit from a CoolAir in their lives.

If you work in a tight, stuffy cubicle or office, the CoolAir can save you from having to compromise your comfort for a centralized cooling and heating system.

  • The CoolAir is also perfect for families. 
  • No young child or baby wants to nap in an uncomfortably hot bedroom. Not only that, the CoolAir’s colorful moodlight doubles as a fun nightlight for children. The CoolAir ensures that you are always resting in totally relaxed conditions.

If you are just looking for a reliable source of consistently cool air, the CoolAir is ideal for you. Whether you are lounging in your living room, working in the office, trying to cook or workout and you find the heat is unbearable, the CoolAir is your most effective and low energy cost solution. 

Evapolar Personal Water Cooling Kit – Performance

Once the cartridge has fully absorbed the water from the tank, the Personal Liquid Cooling Kit can operate at maximum efficiency.

The cooling effect depends on a lot of factors, including ambient temperature and relative humidity. Evaporative coolers work best in hot and dry environments.

Liquid cooling kit has a handy table that shows the expected performance of the cooler: at 25oC with 30% relative humidity, you can expect the air output to be 15.4oC; at the same temperature but at 60% relative humidity, output temperature is 19.7oC.

At 70% relative humidity and above, the Personal Air Cooler may not work at all, and you should ventilate the room or run a dehumidifier.

Testing in a room with an ambient temperature of 22.8C and 53.2% relative humidity with an external probe, I first left the cooler for 20 minutes, to give the cartridge time to absorb enough water.

Once the cartridge was saturated, I measured the output from the Personal Air Cooler at 16.3oC.

The Personal Air Cooler reported that the input was 22.3oC and the output had been cooled to 16oC.

In other words, the sensors are pretty much spot on. You can see the cooler in action with the thermal imaging camera below: the purple part of the image is the cold air.

Should I buy the Evapolar Personal Air Cooler?

Testing performance on a relatively hot summer’s day in the UK, with typical humidity levels for my home, I found that the Evapolar Personal Air Cooler managed to output a stream of air that was considerably colder than the ambient temperature.

It will make working on your desk more comfortable and thanks to the way it works.

Best of all, running costs are extremely low. Air-conditioning units will cool down an entire room and work better in high humidity environments, but they require ventilation and are more expensive to buy and run.

Fans can cover a wider area, but don’t have an effect on air temperature.

For personal use, such as those of us desk-bound or for sleeping, the Evapolar Personal Air Cooler is a great way to beat the heat.

No one can control the seasons or the weather, but you can definitely control how you react to it. You can burn away your comfort by enduring the heat or you could burn away your money by using an air conditioner and racking up those electricity bills.


You could get the CoolAir device and you’d be getting 2 birds with one stone. You won’t have to endure the heat and you won’t use up as much electricity when compared to traditional air conditioners.

Now the CoolAir isn’t for everybody, not everyone is bothered by the heat or their electricity bill, for those people they probably don’t need this device, but…

  • If you don’t want to be the person who is constantly uncomfortable because of the heat.
  • If you don’t want to be the parent whose kids can’t enjoy a good night sleep or even a nap because the heat is making it nearly impossible for them to.
  • If you don’t want to be the person who is constantly grumpy and cranky because the hot weather is frustrating them

Then this is a very good option you should consider, it solves all the problems listed above and more
