Evaporative coolers, also called swamp coolers, rely on this principle, cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it. The 15°- to 40°F-cooler air is then directed into the home, and pushes warmer air out through windows.

Whats the difference between a swamp cooler and an air conditioner?

One of the main differences between swamp coolers and air conditioners is in humidity. Swamp coolers blow air through a wet material. This adds a ton of moisture to the air. On the other hand, air conditioners dry air before releasing it back out.

Why are swamp coolers bad?

Swamp coolers do have the potential to harbor mold and mildew. The pads do stay wet through the season, which means that mold could grow. In more humid weather, mold is more apt to grow. When you turn on the cooler, the mold in the device could be spread through the process of blowing the air out into the ducts.

Are swamp coolers effective?

Swamp coolers are ideal for cooling the air in a home located in a low humidity area. They work by passing air over a wet pad. The water in the pad evaporates into the air, cooling the air and adding some moisture, or humidity, at the same time. In fact, theyre only effective in areas where the humidity is around 15%.

What are the benefits of a swamp cooler?

If you live in a low humidity area, a swamp cooler is your best cooling option. Swamp coolers help control humidity by adding moisture to the air in dry climates. When the house is cooled and moisture is brought in, your home feels much more comfortable. On the other hand, air conditioners actually remove moisture.

Do you leave windows open when using a swamp cooler?

Climate control inside a home with an evaporative cooler depends on proper air balance. A window should be open just enough to allow air pressure inside a room to slowly and quietly close the door to that room. If the door closes forcefully, there is too little exhaust and the window should be opened wider.

When should you not use a swamp cooler?

They have a hard time cooling your home when it gets above 95 degrees. They should not be used when the climate is humid as they use humidity to cool a home. They do require more maintenance from a traditional central air conditioner. They are prone to leaks due to float problems.

Is air cooler with water bad for health?

Why air coolers are good for health Unlike air conditioners, air coolers use water as their refrigerant instead of the CFC and HFC. Thus, it is safer not only to the environment but also to human health. This natural air cooling is proven to be effective even though it does not rely on harmful chemical coolants.

Is air cooler not good for health?

During the runtime of air cooler, water evaporates and increase the humidity in the air. Increase in the humidity is much favorable conditions to increase bacteria, viruses, mold in the water. Because of this reason Asthma patients should be very careful about the usage of air cooler.
