Features To Consider When Buying The Best Evaporative Coolers (Buying Guide)

a) Cooling Area

Before buying an evaporative cooler, you should always read the cooling area specification written on the model description. This will allow you to know if the cooler you are buying is adequate for your space. For instance, garages and workshops are considered larger, cooler areas; hence they would need air coolers to meet this need. While smaller or average-sized areas are considered low cooling areas. It's also important to remember that the cooling area of the swamp cooler you are buying should always be greater than or equal to the area you want to cool.

b) Cooling Pads

There are two types of cooling pads in the market.

Honeycomb cooling pad: They are high density, made of cellulose, and resemble honeycomb in structure. They provide more cooling compared to other types of cooling pads. Honeycomb cooling pads are durable and highly efficient. The downside is that they are expensive.

Aspen or wood/wool cooling pads: They resemble grass in structure and provide less cooling. They are affordable but less efficient and durable.

c) CFM and Square Footage

When considering the best evaporative coolers, there are two dimensions to pay attention to CFM, which refers to cubic feet per minute and square footage.

Square footage refers to the room or area you plan to cool. To measure this, all you need is to measure the length and width of a room and multiply the figures to get the square footage. You’ll need to check the products to confirm if their square footage ratings are compatible with yours. CFM lets you know how much air a machine can remove. Every manufacturer lists this, and this goes hand in hand with your square footage.

d) Water Tank Capacity and Indicator

As the size of your cooling area increases, so does your required water tank size. Selecting an evaporative cooler with an adequate tank capacity will prevent you from constantly having to refill the tank. Outdoor swamp coolers usually have garden hose hookup attachments.

The water level indicator notifies you of the amount of water present in the cooler. When it reaches the minimum level, the empty tank will notify you to refill the tank. This feature saves the swamp cooler from getting any damage on running water-free.

e) Air Swing Delivery System

This feature ensures the reach of air blows by the air cooler in all directions of the space. The swamp cooler comes with an oscillation of 40°, 70°, 120°, and as the degree of oscillation increases, the range of air blown also increases. This is an important feature to consider against the size of your room. As the bigger your space, the higher degree of oscillation you will need.

f) Speed Control

This feature allows you to control the flow of air you want by increasing or decreasing the fan's speed. There are three speeds offered: Low, Medium, and High.

g) Extra Features:

Timer Function: A timer function allows you to program your swamp cooler for uninterrupted running, and once it reaches the set time, it will automatically go off. Swamp coolers come with a maximum timer function of 7.5 hours or 15 hours. Depending on your needs, you can select what works for you.

Wheels at Base: Wheels allow ease of movement. Most evaporative coolers have 4 caster wheels making them easy to move around your indoor or outdoor space.  

Remote Control: This can be considered an extra feature but convenient. It allows you to control your evaporative cooler from a distance with the help of a remote.

h) Power Consumption

When considering buying an evaporative cooler, power consumption should always be top min. Though an evaporative cooler's initial cost is one-off, the running cost concerning power consumption is life-time.

Hence if you come across an evaporative cooler that is eco-friendly and consumes less power, that should always be one worth considering. However, this is also dependent on the size of the cooling area
