Do you feel too hot and the air is too dry? Are you under a heat wave? Then do not miss the Evaporative Climatizers, also called bioclimatizers, which work by cooling the environment based on water and ventilation.

What is an Evaporative Air Conditioner?

An evaporative air cooler is a device that uses water evaporation to lower the air temperature and increase the humidity. Unlike conventional air conditioning systems, which use compressors and refrigerant gases to cool the air, evaporative coolers use a natural process.

The water is distributed over the panel by means of a pump or by capillarity. Thus, the air passes through this panel, causing the water to evaporate and absorb heat from the air, reducing the temperature and increasing the humidity.

In short, its operation is based on a fan that circulates the air and a water pump. Thus, hot and dry ambient air absorbs moisture, becoming cooler and more humid.

But, do they really work?

The answer to our question is yes; The air conditioner really works. And the drier the air, the better the result.

Evaporative coolers are most effective in areas with low relative humidity, where water evaporation is most efficient. They can also help reduce dust and other air pollutants, and are more cost-effective and sustainable than traditional air conditioning systems.

These systems are increasingly used both in individual homes with portable air conditioners and in large buildings.

What are the advantages of evaporative coolers?

Evaporative air conditioners are ecological, as their energy consumption is much lower than conventional air conditioners. In addition, they are less noisy and more portable, as they do not need to install a tube to drain the air. Some models also have an ionizer and filtration system incorporated, which improves the quality of the ambient air.

In addition, they humidify the air which in hot environments becomes very dry.

Many of the models allow you to insert ice into the water reservoir for a greater cooling effect.

These coolers are a good alternative to portable air conditioners.

Pros and Cons of the Evaporative Cooler


  • Very efficient, low consumption
  • Long-lasting water tank
  • Reduced purchase price
  • Portable and no installation
  • Silent
  • Good for humidifying dry air
  • Low level of carbon footprint as it has no emissions


  • Less cooling than an air conditioner

Are they efficient?

Evaporative air conditioners are very efficient as they consume little energy when compared to traditional air conditioning. In addition, they manage to reduce the air temperature by several degrees. You will notice the biggest difference when using it in a very hot and dry environment.

Which Evaporative Air Conditioner to buy?

You have many options on the market and many are similar. You must take into account the area you want to cool and with that choose the power of your air conditioner.

FAQs – Frequently Asked Questions

If you want to have more information and summary, see now the most frequently asked questions.

  1. What is an evaporative cooler and how does it work? It is a device that uses water to cool the air. It works by pulling warm air from the environment into the device through a fan. The air passes through a filter moistened with water, which reduces the air temperature.
  2. In what type of environment is an evaporative cooler most efficient? Evaporative coolers work best in dry environments. Yeah, they release moisture into the air to reduce the temperature.
  3. How to clean and maintain an evaporative cooler? To keep the evaporative cooler working properly, it is important to regularly clean the filter and water container. The frequency of cleaning depends on the intensity of use, but it is recommended to clean at least once a month during the use season.
  4. Can evaporative coolers replace air conditioning? Yes. They are a more cost-effective and eco-friendly option compared to air conditioning.
  5. Can evaporative coolers help reduce allergies? Yes, they help reduce allergies. Yeah, they increase the relative humidity of the environment, which helps relieve nasal congestion and throat irritation. In addition, they use a filter that helps remove dust, pollen and other particles from the air.
  6. Do I need to add chemicals to the evaporative cooler water? It is not necessary to add chemicals to the water. However, it is important to use clean water and change it regularly if it is not completely consumed.
  7. What to do if the evaporative cooler is giving off an unpleasant smell? If it is emitting an unpleasant smell, it is likely that there is dirt in the filter or water tank. In that case, just clean the filter and the tank.
  8. Are evaporative coolers silent? They are quieter than air conditioners. However, the noise level may vary according to the model and power of the device.


Evaporative coolers work and are increasingly used, as are sprinkler fans (or fans with water nebulizers) of droplets with water. Well, they are a low-consumption alternative for cooling hot, dry air in an ecological way. In addition to being lower in terms of equipment and electricity, these air conditioners do not require installation and are always ready to use.

The drier the ambient air, the better result you will get with an evaporative cooler. Therefore, they are very good for use in heat waves.
