Buying Guide For The Best Evaporative Cooler

Cooling Capacity

When selecting a cooling unit, it's important to consider the size of the area you want to cool. Choose a unit with appropriate CFM (cubic feet per minute) for the space you want to cool. A unit with insufficient cooling capacity will not be able to effectively cool the area, while a unit with excessive cooling capacity will be wasteful and inefficient.

Water Tank Capacity

If one wishes to avoid frequent refilling of the cooler's water receptacle, it is imperative to opt for a model with a larger water tank capacity. By doing so, the cooling process may persist for a longer duration without necessitating the replenishment of the tank. Nonetheless, it is essential to acknowledge that a larger tank capacity may also result in a heavier and more unwieldy unit.

Airflow Direction

Different coolers are designed to provide airflow in different directions. Some models allow for vertical airflow, while others provide horizontal airflow. Consider the layout of your space and your desired cooling pattern to choose a unit that can provide airflow in your desired direction.

Noise Level

If you plan to use your cooler in a home or workplace, it's important to consider the noise level of the unit. Some coolers can be quite loud, which can be disruptive to those around you. Look for models with low noise levels to ensure a comfortable and peaceful environment.

Energy Efficiency

It is an important consideration when choosing a cooler. Choose a model with a higher SEER (Seasonal Energy Efficiency Ratio) rating for better energy efficiency. This will help you save money on energy bills and reduce your carbon footprint.


Maintenance is an important consideration when choosing a cooler. Look for units with easy-to-clean filters and minimal maintenance requirements to save time and effort. Regular cleaning and maintenance will ensure that your cooler performs at its best and has a longer lifespan.


A warranty is important for protection against defects and other issues. Consider an extended warranty period for added peace of mind. This will ensure that you can get repairs or replacements if anything goes wrong with your cooler within the warranty period. Be sure to read the terms and conditions of the warranty carefully to ensure that you understand what is covered.

Evaporative Cooler FAQs

  • What is an evaporative cooler?

    An evaporative cooler, also known as a swamp cooler, is an air conditioning unit that uses water evaporation to cool and humidify the air.

  • How does an evaporative cooler work?

    An evaporative cooler draws dry and hot air through moistened pads or media, which evaporates the water and cools the air. The cooled air is then circulated throughout the space.  

  • What are the different types of evaporative coolers?

    The different types of evaporative coolers include portable, window-mounted, ducted, and direct evaporative coolers. 

  • How do I choose the right size of an evaporative cooler for my home or office?

    The right size of an evaporative cooler depends on the size of the space to be cooled. You should consult the manufacturer’s recommendations or consult with an HVAC professional. 

  • How often should I clean and maintain my evaporative cooler?

    You should clean and maintain your evaporative cooler at least once a year or more if you use it frequently. This includes changing the pads or media, cleaning the water reservoir, and checking the pump and fan.

    Evaporative coolers are typically less expensive and more energy efficient than traditional air conditioning units. However, they are less effective in humid climates.

  • Can I use an evaporative cooler in a humid environment?

    Evaporative coolers are not effective in humid environments because the air is already saturated with moisture, so the water in the pads or media cannot evaporate and cool the air.
