Things to Consider
Now that you’ve seen some of the best evaporative coolers around, it’s time to look at the various features and factors that help you choose the best possible model for you. This evaporative cooler buying guide will tell you all you need to know about shopping for evaporative coolers, complete with an FAQ section, revealing answers to some of the most common questions you might have about evaporative coolers.
Choosing the best evaporative cooler
When shopping for an evaporative cooler, you have to ask yourself a few different questions and consider a list of factors. Some factors might be more important to you than others. For example, if you don’t have too much money to spend on your cooler, you’ll want to find the best value model that fits into your desired price range. Or perhaps if you’re trying to find a cooler for a large home or space, you’ll need to focus on one with a lot of cooling coverage and high fan speed settings to cover all that space, rather than a smaller and weaker model.
Ultimately, choosing the best evaporative cooler is all about analysing your own situation, considering why you want the cooler, how you’re going to be using it, how much you’re willing to spend, and what features matter the most to you.
Maybe you only need a small, budget model like the Luma Comfort EC111B, for example, or perhaps you need a more powerful and feature-filled model that can handle larger spaces and comes with additional options, like the Honeywell CO60PM. Read on to learn about the individual factors and aspects of evaporative coolers.
Voltage essentially tells us the electrical power of an evaporative cooler. In terms of voltage, these devices tend to range from 110 to 120V. An example of a 120V is the Essick Air Window Evaporative Cooler, N44W, which will typically have a stronger output and potential than a lower voltage alternative. Voltage isn’t a hugely important factor when choosing an evaporative cooler, but it’s still worth keeping an eye on this detail when comparing different models.
Every evaporative cooler comes with different fan speed settings. Some may only have a couple of options, while others, like the Hessaire Products MC61M Mobile Evaporative Cooler, will have three different fan speeds, and others may have even more. If you’re trying to find the best rated evaporative cooler, having more fan speeds is always better.
Additional fan speeds give you more flexibility with your cooler, letting you adjust the speed to suit the conditions of the space.
Some coolers will also come with remote controls or automated timer settings to change their fan speeds more easily, giving you even more control and flexibility with your cooler.
The air flow of an evaporative cooler tells us how much air the device can move when set on its top fan speed. This aspect is measured in CFM, which stands for cubic feet per minute. The higher the CFM rating, the move air will be moved by the device. It’s important to note that the CFM of a cooler doesn’t tell the whole story, as various other factors will affect how powerful your cooler really is.
However, a higher air flow is always a good thing and is a strong indicator of an efficient cooler. The Cool-Space AVALANCHE-36-VD Swamp Cooler boasts of air flow rising up to 9,700 CFM on max settings.
This is one of the first factors to think about when buying an evaporative cooler. These coolers aren’t all equal. Some are able to handle huge spaces, while others are best kept in smaller areas and won’t have much of an impact in a large home or open environment. The cooling coverage of an evaporative cooler tells us how much space it can cool down. A device like the Honeywell CO30XE Portable is a good option for a small home or apartment, offering up to 320sqm of coverage, while a cooler like the Hessaire Products MC61M Mobile Evaporative Cooler is able to offer much more coverage and is a better suited fan for a whole house.
The water reservoir of a swamp cooler tells us how much water it can hold.
The more water in the machine, the greater the cooling and the longer it will last before needing to be opened up for refilling.
Some coolers, like the Cool-Space AVALANCHE-36-VD Swamp Cooler, are able to store several dozen gallons of water at once, but are much heavier and difficult to move around as a result. Others, like the COSTWAY Portable Evaporative Air Cooler, only have small reservoirs but are more manoeuvrable.
Dimensions and weight
Evaporative coolers tend to be quite big and bulky devices. They’re heavy and hard to move around for many people, so it’s important to think about their size, their weight, where you’re going to install them and how often, if at all, you plan on moving them around. Measuring up at under 17 lbs, the Whirlpool WPEC12GW is the most compact and convenient evaporative coolers. It’s highly lightweight and easy to move around, which can be very helpful for those who plan on using the cooler in different rooms around the home.
If you’re hesitating between two different evaporative coolers, it might be a good idea to consider any extra features each model has in order to help you decide on the best one. Some of the cheaper coolers out there won’t come with any extra features, but some come with a lot of useful bonuses like a remote control to help you operate the cooler and adjust fan speeds from a distance or timers that let you configure the cooler to change speed or turn itself off after a set amount of time. The Luma Comfort EC111B, for example, comes with a timer and remote control, while the Honeywell CO30XE Portable comes with a special filter for removing dust from the air.
Evaporative coolers aren’t always cheap. They can cost anywhere from one hundred dollars up to almost a thousand. Before shopping for your next swamp cooler, it’s important to consider your budget and calculate how much you’re willing to spend on the device. More expensive coolers will typically be more efficient and effective overall, having additional features, stronger fan speeds, and better cooling coverage than others, so if you want the best performance, you may have to pay a little extra. However, it’s perfectly possible to find great value evaporative coolers like the NewAir AF-1000W.
Evaporative coolers, as the name implies, work by cooling the air through the evaporation of water. Water has to absorb a lot of heat in order to evaporate, so this process can be used very effectively in order to lower the surrounding air temperature. It uses a lot less energy than refrigeration and the concept of evaporative cooling has been used for thousands of years. Put simply, an evaporative cooler will make use of water-soaked pads to cool down the air. The fan pulls hot air into the unit, which then flows over the pads to evaporate the water, which effectively absorbs the heat as it passes through.
Many people prefer an evaporative cooler over other devices, for example, cooling fans, due to their energy efficiency and affordability, but they do require a little bit more regular maintenance than a classic air conditioning unit. You’ll need to give them a clean on a regular basis and change the cooling pads too. Keeping your cooler clean is very important if you want to help it last for years without any problems, and cleaning should be done on a monthly basis, at least. Simply use a soft, damp cloth to clean the surface of the cooler. You’ll also need to check the pads every now and then, changing them once a year or more often, depending on the climate and usage of your cooler.
This really depends on the model of swamp cooler you buy. Some models are much noisier than others. It also depends on where you place the machine and how sensitive you are to noise. Some people barely notice the sound of an evaporative cooler, while others can be more easily bothered by it. The best evaporative coolers can produce around 40-50 decibels of sound, but other models can go up to 70 or even 80. For reference, a vacuum cleaner can typically produce over 70 decibels of sound, while many regular air conditioning units can range from as low as 40 up to 80 decibels or more.
The whole concept of an evaporative cooler is to make use of water to cool down the air. Without water, the cooler is basically just doing the same job as a simple fan, so it loses almost all of its efficiency and cooling potential. It is still possible for evaporative coolers to keep running when there is no water left in the tank, however, while others will automatically shut down or show some kind of notification to let you know that water needs to be added. This is why it’s important to practice regular cooler maintenance and replace the pads over time to keep your cooler in perfect condition.
Overall, our best-rated evaporative cooler is the Honeywell CO60PM. Compact, powerful, and versatile, this cooler has it all. It gives you everything you could desire in a cooler, working wonderfully in any environment and providing powerful instant cooling whenever you need it.
The second best swamp cooler is the Hessaire Products MC61M Mobile Evaporative Cooler. Built to last and offering stronger technology than leading alternatives, this cooler is so fast and powerful, you’ll feel the air temperature drop almost instantly, even on the warmest and sunniest of days.
Third on our list of best evaporative coolers is the Honeywell CO30XE Portable. One of the few coolers that can be used reliably both indoors and outdoors, this device is perfect for parking out on the patio or deck, while feeling equally at home in a bedroom or living room.
