What's to like about the Costway Evaporative Air Cooler
What’s so great about this air-cooling device is the fact that it can be used to cool an entire room. Its swing mode can disperse cool air in all directions, thus providing cool air not just to people seated in front of the unit.
What's not to like about the Costway Evaporative Air Cooler
Some people have complained that this unit can only cool off small spaces.
Because all they do is cool the air, it may seem like all air-cooling systems are the same. Then again, that statement cannot be more untrue. Air-cooling systems are all different and range in size, cooling capacity, airflow, and extra features.
It is important to know exactly what you want before you start looking for one as this will help narrow down your search. Here, we will introduce you to five of the most crucial buying considerations when it comes to choosing an efficient evaporative air cooler.
Types of Evaporative Coolers
There are three main types of evaporative air coolers that you need to be aware of. To help break down the three different models, we have created a quick overview of what each version does:
A direct evaporative air cooler also goes by the term of “swamp cooler”. These devices are energy efficient and are the easiest version to install. They are inexpensive, plug directly into an outlet, and don’t require much maintenance.
On the other hand, indirect evaporative air coolers are installed into one place in your home and can’t be moved. These versions do not enhance the humidity in a room, but they shine when it comes to reducing the overall temperature in a space. These units often are more expensive and require professional installation.
The last type of evaporative cooler is the portable version. This version is a small unit, usually weighing under 10 pounds and can be picked up and carried around. Many of these units feature USB charging ports or can be plugged directly into a wall outlet.
While these are good for small areas, portable evaporative coolers can’t really produce enough cool air to fill a room. Still, they are relatively inexpensive and can get the job done.
The cooling area changes depending on the system you purchase. The best evaporative coolers can cool rooms up to 900 square feet or more while others are only good at cooling a small space.
Overall, you’ll need to check the specific model to see how large the cooling area is. We would always recommend units with a moderate range, as these are best for home use.
Air Volume (CFM)
CFM or cubic feet per minute is known as air flow. Basically, this translates into how fast a fan can produce air. The larger the CFM, the faster the room will cool.
A lower CFM will produce a moderately cold room and may take more time to cool a larger area. Generally, you would want a CFM at around 800.
To power an evaporative air cooler, it generally costs 0.10/kwh or approximately two cents every hour. However, if you have a more extensive system, you may be looking at a higher rate.
An industrial-level evaporative cooler, which cools up to 3,000 square feet, runs at two cents every hour, which is a very reasonable rate.
Water Tank Capacity
When it comes to water tank capacity, it’s going to be highly dependent on the dimensions of the unit. The bigger the system, the more likelihood the water tank is going to be larger. But then again, why would you want a large water tank?
Water particles are added to the fan to help produce cool humidity in your home. This can help alleviate dry skin, coughs, and help stuffy noses. The larger the water tank, the less frequently you’ll need to replace the water. Typically, you’ll need to replace a five-liter tank every three to four hours depending on the settings.
What is an evaporative cooler?
An evaporative air cooler is a device that uses water to help produce cold air. The cooling system features a water tank that has pads that soak up the water. At the same time, it also disperses the water molecules into the air and produces a cool breeze from a fan.
Some evaporative coolers feature filtration systems and can be packed with ice. As a result, they deliver clean and refreshingly cool air.
How to use evaporative coolers?
Evaporative coolers aren’t complicated and are similar to any other household appliance. Most units can be plugged directly into a wall outlet and will automatically go to work. The only steps you will have to take is to fill the water tank up and change the settings to your liking.
How do evaporative coolers work?
The process is pretty straightforward. First off, the cooler will suck in hot air through the back of the system and suction it through grates. From there, the air goes through the system and circulates with water.
The pump will then cool the air before dispersing it through the force of flexible blades. Lastly, the air will be pushed out of the system and spread throughout the room.
How to install evaporative coolers?
With most modern evaporative coolers, you won’t need to install them unless you get an indirect system. We always recommend following the manufacturer’s instructions and making sure that you have stable support for your system.
However, we do recommend getting a professional to install your system, as this will ensure that it doesn’t come crashing down. If you’re more into DIY projects, we can walk you through the necessary steps to install a system into your home:
- Begin by preparing a window. If you are installing a swamp cooler, you’ll want to measure out a window and make sure that the dimensions fit.
- Then, place the cooler in the window. The next step is to take the cooler and place it into the window. Use blocks or other stable objects to create an even surface.
- Level the cooler. It’s essential to take a level tool and make sure that the system is not uneven. After you make level marks of where you want the cooler, attach the system using chains.
- Next, take waterproof stripping and use it to close any areas around the window that may leak. You will need to do this as water can form around the crevasses of the building. This will cause a buildup of bacteria and mold.
- Lastly, fill the cooler with water, and you’re ready to use it!
How to clean evaporative coolers?
Similar to any type of filtration system, you are going to want to use white vinegar and water. The vinegar mixture will help break down calcium buildup, which is common with any appliances that come into contact with water.
How can you do this? Mix three parts of water to one part vinegar and use a toothbrush to scrub the inside of the water tank softly. If your water cooler uses a filter, be sure to change it out for a new one. However, if the filter is a reusable version, wash it according to the manufacturer’s instructions.
Once you’re done, fill the tank back up with water and use it as you normally would.
When it comes to finding an effective cooling system, it is essential to look for one with a decent-sized tank, one that can cover a large area, and one that can last for at least a few hours before it needs to be refilled.
While each of the five air-cooling systems on our list is considered the best ones on the market, there needs to be one hailed as the best evaporative cooler of 2018. Out of all the ones on this list, the Honeywell Evaporative Air Cooler is the one that fits this description.
The Honeywell Evaporative Air Cooler has mainly positive reviews, and the only downside we have found is that it doesn’t work well in humid areas. However, if you do live in a humid place, you can opt to keep the water tank empty.
