While some of the water is recirculated through the system, some will inevitably leave the cooler in the air blown out by the fan. Because of this – and the fact that the water in the absorbent pad or membrane can grow stale – you need to keep the air cooler filled and change the water in the tank daily. You should also wash the pad or membrane occasionally or you might get some pretty nasty smells. Is there anything worth looking out for? This depends on the air cooler you have. Most use some sort of water pump which can be damaged if you run it without filling the tank. However, our air coolers have a “cool” button which lets you switch between the air cooler mode and a fan-only mode. When you press that button, the water pump shuts off, meaning you can use it as a normal fan. This is good for those days when it’s not quite hot enough to warrant that extra cooling power! Do Air Coolers Humidify the Air?

Additional research and reporting were done by Mattie Schuler, an adventure journalist who specializes in the outdoor industry. Air coolers use a natural process called evaporative cooling to chill the air. As a result, they don’t use any complex machinery. This means they cost much less and are smaller, lighter, and more portable! They also use much, much less electricity, so they’re eco-friendly and cheap to run. They don’t have the same cooling power as an air con and you shouldn’t expect them to, but they still provide more than enough chill for most homes and offices! What is Evaporative Cooling?As the name suggests, it also has basic smart features. With the cooler connected to your Wi-Fi network, you can control it from your smartphone or even an Alexa or Google Assistant speaker, although the voice commands don’t cover much more than switching modes or turning the unit on and off. We also like the fact that you can clean the filter under the tap or in the dishwasher, and that the illuminated side panels can be set to glow with a choice of seven colours if you fancy a little mood lighting. While it could be easier to remove the filter and get the water tanks in and out of place, for sheer value and convenience, this cut-price compact cooler is a winner.

When water droplets collide with each other or with a hard surface, they generate a negative electrical charge which attaches itself to the oxygen atoms in the air. These atoms are negative ions. This is quite complicated and it sounds quite bad, but don’t worry; negative ions are actually really positive! This cheap cube desktop cooler doesn’t have a lot of bells and whistles, but it’s a good way to chill your fevered brow while you’re plugging away at your desk. Its two removable 300ml tanks mean it doesn’t constantly need refilling, and you can freeze them if you want some extra cooling. The three-speed fan gives you options from subtle breeze to full-on gusting, and on the lowest setting it’s quiet enough that it won’t disturb you while you work. Air coolers are much less complex than air conditioners, so they need much less maintenance. All you really need to do is ensure you change the water in the tank daily. This will prevent the water from becoming stagnant and prevents bad smells from building up! Yes, air coolers are an effective and energy-efficient way to cool your home or office. Air coolers use the simple and natural process of evaporating water to lower the temperature of the air. Unlike air conditioners that use refrigerants and compressors, air coolers are more cost-effective, without the need to run a vent pipe out of the building. As air coolers work by increasing the humidiity of the room, it's important to consider your climate and personal preferences when choosing the right air conditioning for you.With some air coolers, there’s a risk of adding to the room’s humidity, which can be a problem if it already suffers from excess humidity. Plus, where water tanks are open inside the cooler, there’s also a risk of spillage – which can be a worry if you’re using a desktop model plugged into your laptop or PC.
