Best Evaporative Air Cooler to Ensure Comfort on Hot Days

The best evaporative air cooler can act as an affordable alternative to an air conditioner, especially in areas with humidity levels of less than 40%. It can be difficult to keep cool, especially when living in a dry region, and standard AC units may not be enough. Evaporative coolers, also called swamp coolers, are air conditioners that employ vaporization. These machines lower the temperatures by pulling in warm air and then moisturizing it. In addition, they consume less energy because they only operate a fan. These air coolers are cheaper to run and eco-friendly, but if you live in a humid air location, these machines are unnecessary as they will make your home muggy.

If you want the best evaporative air cooler in the market, which will also be a money-saving solution for your home, we have listed some of the best options with their pros and cons. Read on to find important considerations on what to look out for when shopping to understand better.

Factors to Consider Before Purchasing the Best Evaporative Air Cooler

1. Cooling Area (CFM)

The cooling area is an important factor to consider because this lets you know whether the evaporative air cooler will be effective in cooling your room or not. To check the cooling area, you will need to check the cooler CFM rating sized in Cubic Feet per Minute (CFM), which usually describes how much air volume a specific cooler can process.

If you need an evaporative cooler for your outdoors, then opt for a powerful CFM rating of at least 1000 CFM, and this will be able to cool a large space. Notably, keep in mind that opting for the big evaporative cooler will make you have humid and uncomfortable air. Also, it would be ideal if you opted for water and UV-resistant choice as this will help your evaporative cooler withstand any temperature or element.

2. Water Tank Capacity

Evaporative coolers work by pulling the hot and dry air through a wet media pad. The hot air will cause the top moisture layer on the pad to evaporate, lowering the air temperature in the cooler by up to 20 degrees. Therefore, a water source is important because it will keep the media pad wet. The water for these portable swamp coolers is held in internal tanks that can be as small as a gallon for the portable evaporative coolers and up to 10 gallons for the whole-house model.

The larger the tank capacity, the longer the best evaporative cooler can operate, so opt for a swamp cooler of at least 5 gallons to run the cooler through the night. The evaporative coolers usually utilize the water from the tank based on the CFM. Some outdoor models usually have a garden hose hookup that refills themselves instead of manually doing it.

3. Power Consumption

Purchasing the best swamp coolers should be a one-time investment and if you come across two models, always pick the one that consumes the less power despite the price. Also, how large the area you want to cool is should determine the power consumption you should opt for, and there is a general rule that there will be an increase in power consumption if there's an increase in the cooling area.

4. Air Swing Delivery System

This system is the oscillation feature in some evaporative air coolers where oscillating louvers in the cooler will control how far the evaporative cooler can oscillate, ranging from a 0 degree fixed position to an arc of up to 120 degrees. Determining the right air swing delivery system will need a user to consider the size of their room, and the larger space, the higher the needed degree of oscillation.

5. Timer

A timer function will allow a customer to program the cooler for an uninterrupted working period, and once the set time is reached, the evaporative cooler will switch off automatically. The best evaporative coolers usually have a maximum timer function of around 15 hours with switch buttons of one to four hours. Still, they might come at an expensive price if they have this option available.

6. Cooling Pads

Cooling pads also referred to as media pads, are usually responsible for adding moisture to the mix. They work by getting wet in cold water, absorbing the heat easily from the air, and delivering a cool breeze. A large cooling pad is usually nice because it is made from materials with cellulose or wood. Still, you also have to consider how often you will need to replace them as the exotic options are quite pricey to replace, making the maintenance of evaporative coolers cost higher.

7. Decibel Level

The decibel level is not important if you run your evaporative cooler outdoors, but it's very important to choose a portable air cooler. Notably, it can be difficult to find the DBA rating on some evaporative coolers but always check because this rating tells you how loud your evaporative cooler will be for indoor and outdoor use.

8. Portability

The best swamp coolers would be the ones that are easy to move around, and these usually come with a lightweight but sturdy body and also wheels. This is an important consideration because most evaporative coolers usually handle a single room simultaneously, and the wheels minimize the tank spilling or shifting.

9. Air Filtration

This usually prevents allergens like dust and pollen from being pulled into your home. These evaporative coolers usually pull air through a filter before they hit the cooling pads and removes any airborne irritants. Some of the best evaporative coolers usually feature odor-blocking or activated carbon filters.

10. Types of Evaporative Coolers

There are different evaporative air cooler types, and they differ in terms of mounting location, size, and the angle at which cool air is released. They include:

a). Portable evaporative air coolers

These are the most popular options, and they stand on a wheelset and come with top and side handles to move the portable evaporative cooler around.

b). Window evaporative air coolers

These coolers are designed to be placed in a pen window, and they pull hot and dry air from outside directly and cool your home inside. They are more effective than portable coolers, but they come at a high price and are not popular.

c). Down discharge evaporative air coolers

These units are usually mounted on the roof, and they blow air and cool the whole house, but they can be prone to leaks if they are not installed and sealed properly.

d). Side discharge evaporative air cooler

Side discharge coolers are the most common types because they are both window coolers and portable and push air horizontally. They are not that effective, but they are easy to access, maintain and prevent water damage from unnoticed leaks like in down discharge models.

e). Swamp cooler

This term is used interchangeably with an evaporative air cooler. Some manufacturers usually refer to the whole home units as swamp coolers while calling the small units evaporative air coolers. Despite the term used, ensure you check the product information to guarantee you are getting the type of product you want.


Frequently Asked Questions on the Best Evaporative Air Coolers

1. Are evaporative coolers hard to maintain?

No, evaporative coolers have low maintenance unless you have a whole-house evaporative air cooler. Then, the only maintenance needed is changing the media pads, draining the tank, and regularly cleaning the reservoir to prevent the growth of bacteria.

2. What is the difference between evaporative air coolers and air conditioners?

The main difference between the two is that evaporative air coolers usually add humidity to your air. In contrast, an air conditioner will dry it out or remove it not to be used simultaneously.
