What is an Evaporative Air Cooler

Every time a stiflingly hot summer comes we wishfully think how great it would be to have a whiff of fresh air. Stop dreaming, start acting! Buy an evaporative air cooler, it is a perfect device to cool and moisturize the ambient air, making it a lot easier to breathe. And it is cheaper than an air conditioner. So, what is an evaporative air cooler? Like we said above, it's a device that cools and moisturizes the air in your room. The mechanism is pretty simple: there is a filter at the back continuously showered with water and the fan that draws the water through this filter causing it to evaporate; thus, the air is moisturized and cooled. The evaporative air cooler does not require mounting, just plug it in, pour the water into the tank, and select a mode. Mostly, the evaporative air coolers are used indoors but some innovative models work perfectly well outside too. The only limitation here is that as the evaporative air cooler cools the air with water, it is designed for dry air mostly. If the air around is already moisturized, the device will be less performing. But in a hot dry air, it will make the difference! And as a cherry on the top, the evaporative air cooler is a really energy-efficient device! Your electricity charges will be cut significantly.

For those living in the regions of high humidity and wishing to maintain comfortable temperatures in their houses, we can offer several other reviews: portable air conditioners, split air conditioners, and window air conditioners.

What Features to Compare

Starting to look for an evaporative air cooler, first, consider its Design and Usability. For example, there are stationary evaporative air coolers that are mounted on the roof and are connected through a special ventilation duct. Or there are portable evaporative air coolers that have wheels and can be moved from one room to another. The differences in design are often also important: a slim tower portable evaporative air cooler will be more convenient in a small room than a bulkier one. By contrast, for commercial use, it will be better to buy a monoblock portable evaporative air cooler with a big diffuser. Also, such device can be used outdoors — on a patio, in a garden, or by the pool. The wheels make it easier to move the portable evaporative air cooler. 

Same as any household device, evaporative air coolers have different technical characteristics, and the most important one is probably Performance. It largely depends on the room size; the bigger the room is, the more powerful cooler you need, obviously. As the evaporative air coolers operate by evaporating the water, the water tank volume should also be quite large for the cooler to function longer (before you need to refill the tank). If you are busy or just don't want to refill the tank from time to time, there are models that take water just from the water pipes. The water, in this case, is supplied continuously and you don't need to participate. In a battle "evaporative air cooler vs air conditioner", when discussing energy efficiency, the former wins even without trying. They consume less energy to provide approximately the same temperature. Just look at the amount of energy your future evaporative air cooler needs and at its airflow (shown in CFM), compare them to those of an air conditioner. The difference is seen by a naked eye. The last point that we include with the performance is the noise level. We recommend you to keep in mind that more powerful evaporative air coolers might be a bit loud for a small closed room. You buy a cooler to work and rest in a cool room, right? The noise is a distraction, so take it into account. 

Control and Functionality can vary from model to model, too. For instance, the oscillation feature can help you control the air flow direction, and it can be controlled either manually or automatically. Some models can have an additional compartment for ice to prolong the time the evaporative air cooler operates at one fill. Also, the ice adds a bit of "frosty" feel to the air. The water level indicator will show (or even notify!) you that it is time to refill the tank. Control-wise, there are two major distinctions — some evaporative air coolers are controlled manually and some electronically. Manual evaporative air coolers are easy to manipulate and reliable. Generally, they might have fan speed adjustment, several operating modes, and oscillation. evaporative air coolers with electronic control usually have more options. There can be a timer, a sleep mode, an auto-oscillation, a Nature mode, and they can be managed with a remote control. Before you make your final decision and purchase an evaporative air cooler, carefully think about everything we've mentioned. If you are buying an evaporative air cooler for commercial use, a portable device with a constant water supply, high air flow, and mechanical control will probably be the best option. But if all you need is a device to cool and moisturize a small room to get the most comfort, then the smaller size and electronic control might be a better choice.

Honeywell CS10XE

Money-saving Comfort

If you live in a dry hot climate, a conventional air cooler is probably not something that you would buy — they make the already dry air even drier. But what to do? Well, you know how the saying goes: "Where there is demand there will be supply". So, Honeywell decided this is a good way to apply their efforts and created this Honeywell CS10XE Indoor Portable Evaporative Air Cooler. With this device, you will easily adjust the climate in a room of 150 sq.ft, make the air cooler and fresher. The cooler is quite compact and does not take a lot of space. Also, it is equipped with wheels for additional portability. The water tank is fairly big and is able to provide cooling for up to 6–8 hours continuously. This means that you will be able to enjoy decent temperature almost whole day or night. In order to provide most even cool air distribution, the manufacturer implemented automatic louvers oscillation. There are two ways to control the operation, you can use either a convenient electronic panel at the front or a remote controller. The timer feature will offer you the option to turn the evaporative cooler on for up to 7.5 hours when you leave, for example. This is really convenient — you will then come back to an already chilled and fresh room. Or you can use the timer when you go to sleep. But we have left the best part to the end. To be the cherry on the top. You'd think a device with this number of features would probably empty your pockets on bills. Not at all! During operation, Honeywell CS10XE only needs 100 Watts per hour. It's like a light bulb, no way an air conditioner can compare. So, make your room comfortable with this wonderful evaporative air cooler!

Review of Honeywell CS10XE Indoor

Some Tips

  • Maintenance is important. Evaporative air coolers lately are much easier to use but maintenance is still necessary. Look after it to be clean and to work properly, especially if the forecasts warn you about the coming heat.
  • For the same reason, models with bigger water tanks are more convenient. No need to change water too often.
  • Do not turn on an evaporative air cooler and an air conditioner at the same time. These two devices do different jobs and forcing them into a conflict may result in your electricity bills skyrocketing.
  • Clean the filter regularly. Water filters in evaporating air coolers are made to stop any impurities to ensure maximum evaporating. But filters do not dispose of those impurities for good, they stay on the filter. And when they accumulate, the evaporating slows down or even stops. If this is not a reason enough for you, we can add that accumulation of water impurities on the filters may lead to weeds growing. And weeds smell. You do not want your room to smell.

What Else You May Need

To control the moisture level in the room, as yet dehumidifers and humidifiers are the best devices available.
