The hot weather has continued for a while and you cannot stand being in your home any more, and the outside feels no better?

Or perhaps you have an office in a non-air-conditioned room, and during hot summer days you literally stick to your chair? We all know this problem, don’t we? We all realize as well that even the best fans give little relief during high temperatures; besides, by directing the air stream straight at yourself, you can easily catch a cold.

You can, of course, invest in professional air conditioning, which will surely be effective at freeing us from the heat, but the cost of its installation is extremely high. There are portable air conditioners, too, similarly expensive and rather not very convenient, which in some way must be able to release air through the window. However, there is also a product called CoolAir, a small, portable air conditioner which is supposed to provide relief on hot days, without costing a fortune. Is this device really noteworthy?

Product description as prepared by the manufacturer


17 x 17 x 17 cm – yes, this is the exact size of the small box which, according to the manufacturer’s assurances, should to a large extent resolve the problem of unbearable heat in apartments or offices. Even the smallest desk fans are bigger, so at first glance, the device may seem rather insignificant.

The manufacturer, however, explains on its website the details behind the principle of this small machine’s operation. The CoolAir portable air conditioner is equipped with a fan with three speed settings, a water container and a special filter that plays a very important role in the device.

The filter soaks up the water collected in the container and the fan behind it pushes in hot air from the surroundings; this air, flowing through the filter, generates the phenomenon of water evaporation accompanied by a significant temperature decrease. As a result, the air behind the filter is already significantly cooler, and also humidified and purified, which is an additional advantage of using this equipment.

The portable air conditioner is of course not a device suitable for cooling very large rooms. According to the manufacturer, this air conditioner in a short time provides pleasant air in its surroundings, and its portable form makes it possible to set it anywhere in the office or home.

Cooling efficiency

Can such a miniature air conditioner actually be effective in its operation? Taking advantage of water evaporation really gives you a lot of hope that the air coming out of the fan will be pleasant. We must remember that standard fans cool the air only slightly, using momentum, but do not humidify it.

The very fact that the air conditioner produces nicely humidified air gives us the certainty that staying in its vicinity will give us at least a moment of respite from heat. No doubt the device can boast high operating efficiency, for which it needs water – according to the manufacturer’s assurances, filling the whole tank allows for about 8 hours of effective operation at the lowest setting of the fan speed. At higher speeds, the operating time will of course decrease.

Main features

Too hot?

Cooling with such a small device is not the only advantage that CoolAir can boast of. Among other important features are:

  • humidifying air;
  • filtering out pollution.

We have already mentioned humidifying; purifying, in turn, is a useful side effect of the way this device works. The air flows through moist filters, on which dust, mites and various microorganisms settle. The filters themselves, of course, have a certain lifespan and after some time are subject to replacement.

Saving energy costs

In addition, the device has a really low power consumption. As the manufacturer assures, in order to operate the device needs as little energy as a small desk fan. The equipment is also very portable, it can be taken even under a tent or into a trailer. An additional advantage is the eye-pleasing form. Its nicely designed case can be backlit by LEDs. The device allows you to turn off the backlight, turn on a single, static backlight or a color-changing one.

Customers’ reviews

All this may still sound not credible enough, but the effectiveness of this small air conditioner is also confirmed in the opinions expressed by customers.

We were able to find an additional, interesting tip in them. To increase the efficiency of the fan, you can pour in water that has previously been chilled in the refrigerator or in the freezer.

What is the price of the device and where can you buy it?

How much does this device cost? Although the manufacturer frequently organizes sales promotions, for many people the price may be rather high. At the moment, with a 50% discount the device is fairly affordable, but fortunately, we can significantly reduce this price.

The more devices we order, the lower the unit price. You can have devices for several rooms or arrange making a purchase together with family and friends. Why is it worth it? For example, when buying 3 fans, we get 2 more at no charge at all.

    got one little question. How long do those filters in the device last, and how much do they cost later on? Can you switch them easily?

  2. pasquale arevalo says:

    I’m looking for people who have already decided to buy it. Let me know if it will work in an 11-meter room where I have my office. Unfortunately, it’s right under the roof and in the summer it can be unbearable, and I can’t afford air conditioning…

  3. beauregard potter says:

    Hey. What’s the period of warranty on this device, does anybody know?

  4. kenneth beavers says:

    do you know any info on how loud the fan is at each of the speed settings? I’m looking for a quiet but efficient fan, so it wouldn’t wake up family members sleeping in the same room as me.

    Why is the term “humidify” used, instead of dehumidify, as less humid air is cooler ? Just wondering.

    1. Anonymous says:

      I agree. We’re always taught that an airconditioner DEhumidifies the air. Hot moist air (humidity) is what makes the temperature seem hotter than it actually is.

        I totally agree. Why do we want to add MORE humidity to humid air?? The more humid, the hotter feeling. A lot of misleading advertising. These are NOT true ‘AC’s……. they don’t take humidity OUT… and they can cool a whole room down, even a tiny one?? C’mon…..we’re not all so gullible…
