How Do I Choose the Best Evaporative Cooler?

Evaporative cooling is a simple, healthy, eco-friendly and cost-effective way of cooling a space. The first factor to consider when getting an evaporative cooler is your climate, as evaporative coolers work best in arid environments. They work by absorbing warm, stale air into the unit using a fan. This air is cooled when it passes over water-moistened pads. This process can cool the air by as much as 30 degrees. This cooled air is then circulated throughout your environment. Because this air is circulating naturally, the temperature of your environment will most likely be four to six degrees lower. Due to this process, evaporative coolers are most effective when the weather is dry and hot. They are least effective in warm, humid environment because the air is already saturated with moisture.

There are two basic types of evaporative coolers:
  • Portable evaporative cooler: portable evaporative coolers are designed to be moved around. They come with casters to enable movement. They are mostly lightweight and are easy to transport. They are more suitable for personal cooling.
  • Window-mounted evaporative cooler: this type is designed to be situated in a particular area in a room. Most models can be easily installed in vertical or horizontal window. They are more energy-efficient than window air conditioners.

If you are on a tight budget, consider evaporative cooling. It is relatively more affordable than other traditional cooling methods. When compared to air conditioners and fans, evaporative coolers are 50% less expensive. As a matter of fact, an average evaporative cooler can operate for eight hours at the cost of a dollar. To get the best out of an evaporative cooler, you need to get a cooler of a suitable size for your space. If the cooler is too small, it might not effectively cool your space, thereby wasting energy.

You may also need to consider how much maintenance a cooler will require. The method of caring for a portable evaporative cooler is slightly different from that of window-mounted swamp coolers. The performance and life of the cooler is primarily determined by the basic maintenance, little cleaning and shutdown of the appliance. For the portable evaporative coolers, the filter and water curtains should be cleaned every two weeks with lukewarm water and a little detergent to prevent a buildup of dirt – especially during long periods of usage. The outer casing can be cleaned with a damp cloth. The window-mounted evaporative cooler, on the other hand, will require a change of the moisture pads, cleaning of the pump and oiling of the motor any time it is about to be used for a warm season.
Price
The price of any product usually depends on a lot of things. Factors like brand and quality can affect the price of a product. Though price is quite an important factor, you must consider the features which have the greatest impact on the price and whether they are features you can afford to skimp on.

The price range for evaporative coolers is relatively wide. You can get one for as little as $90 or as much as $500 and though we saw many cheap evaporative coolers in the market, we deliberately ignored them so we can present to you coolers delivering real value for your money.
Features
Evaporative coolers, just like all home appliances, have a variety of convenience features that make operating them easy. These features also affect the price of the evaporative coolers. Here are some features to consider before purchasing an evaporative cooler:
  • Water consumption and tank capacity
  • Oscillating louvers
  • Ice compartment
  • Remote control
  • Timer
  • Multiple cooling speed
  • Air filtration
  • Fan motors
After selecting the features that are important to you, compare the prices of those evaporative coolers with those features before making a purchase.
Construction and Design
Evaporative coolers require water to keep cooling pads wet. Depending on the size and the temperature, an evaporative cooler can use up to 3 to 5 gallons of water per day. The size of the water tank determines the amount of time it will last before needing to be refilled. Some models have water compartments that can be refilled directly using a hook up hose while others have removable water compartments that you must take out before refilling. Some can even be connected to your continuous water supply. It is important to note that the amount of water your evaporative cooler consumes will affect your operation cost.

There are evaporative coolers with at least two speeds (high and low) and a fan-only option. Evaporative coolers with multiple speeds allow you to control the cooling efficiency of the units. The fan-only option can be used to save water by turning off the water pump so the air is not humidified. This way you can use it as a conventional fan when the weather is too humid for evaporative cooling. Though evaporative coolers only use a little electricity, it is more energy efficient to find a model that has the fan-only option. High speeds can be used during the hottest hours of the day when you need to lower the temperature of the room especially when your cooler has been off for some hours, while low speeds are good for the night when the weather is cooler.
Performance and Ease of Use
Oscillating louvers are a feature that allows you to adjust the main airflow to the direction where you need it without moving the cooler itself. This is particularly useful when you need to cool an area with a higher concentration of people. A large amount of area is cooled by the moving back and forth of the oscillating louvers.

The ice compartment is designed to hold ice which improves the cooling efficiency of the unit. Ice is stored in the ice compartment and it is incorporated into the cooling process.

Some evaporative coolers come with remote controls and timers. The timer can be used to save a great deal of energy. With it you can program your cooler to turn off at a particular time of the day or when your space is as cool as you want it. The remote control, on the other hand, allows you adjust the settings of your evaporative cooler from a comfortable distance. It saves you the stress of always getting up to operate it. Some coolers come with thermostats as well. The thermostat can be programmed to turn off the cooler when it reaches a certain temperature rather than a particular time.

Most evaporative coolers have air filters that eliminate dust and allergen particles. This air filter function is performed by the moist pads. Some coolers have activated carbon filters for filtering odor and inbuilt air purifiers with ionizers and HEPA filters. This protects you from allergic reactions if you are asthmatic or have pets at home.

Lastly, it is wise to stick with brands that are reputable in manufacturing evaporative coolers. Top brands offer warranties and guarantees for their evaporative coolers. This eliminates the burden of fixing the unit or worrying about replacement if it breaks down.
