Without proper care, portable evaporative coolers, sometimes called swamp coolers, can become breeding grounds for mold and fungus. These infestations thrive in dark, damp areas with stagnant air and can cause a wide range of respiratory problems for people exposed to them. The good news is keeping your portable evaporative cooler mold-free is easy with some simple maintenance and preventative measures. Continue reading

Summer is approaching very fast, and this summer is expected to be one of the warmest on record. Most people in the United States use air conditioners to cool their homes, which means summer is also when their electricity bills spike. Air conditioners consume large amounts of electricity. A central AC system consumes 21 times as much electricity as your desktop computer or refrigerator. A window mounted AC unit consumes 5 ½ times as much.  Depending on where you live, your air conditioning will cost you anywhere between $160 and $660 this year. What if there was a more cost effective way to cool your home? Continue reading

The Many Reasons to Own an Evaporative Cooler

For those of you that live in hot and dry climates with low humidity levels then you can absolutely benefit from an evaporative cooler, also known as a swamp cooler. Instead of spending a ton of money on an air conditioning system, evaporative coolers are a profitable alternative when it comes to being economical and energy efficient.

Living in humidity is extremely uncomfortable and can even lead to death. The high temperatures are dangerous for the human body and it’s imperative to keep the humidity levels within your home at a safe range. Evaporative coolers work to cool the air surrounding you without using harmful coolants or chemicals. This guide helps explain the benefits using an evaporative cooler that will enable you to control these types of humidity levels.

What is Humidity?

Humidity is the water in the air around you. It is a gaseous state that is invisible to the human eye called water vapor. It is expressed as a maximum percentage that the air temperature can hold at, and it is measured in relative or absolute terms. Humidity also determines the probability of dew, fog, and precipitation.

The Dangers of Humidity

Humidity makes our bodies feel hotter, which makes it difficult for us to easily cool down because we lose water and chemicals that our body needs. Our body tries to adapt to the changes in temperature to keep cool by sweating, changing blood circulation, and increasing respiration.

Without the proper techniques to cool down, we can suffer from:

  • Heat cramps

    • Heat can cause muscles to cramp.

  • Heat exhaustion

    • We lose fluids and salt within our bodies when we sweat a lot.

  • Fainting

    • Blood pressure can drop tremendously in the heat, which can lead to fainting.

  • Heatstrokes

    • Our body temperatures can rise to a dangerous level that cause us to suffer from a heatstroke.

Humidity Levels Best for Evaporative Coolers

Evaporative Coolers work best and are more effective in areas with low humidity and hot temperatures. They should operate in humidity levels below 50%, which are usually found in southwestern US states where the air is hot and dry.

How do Evaporative Coolers Work?

The main purpose of an evaporative cooler is to lower indoor temperatures by combining cooling properties of evaporating water with an air moving system. With open windows, airflow is controlled to allow the unit to push warm air outside, add moisture, and remove dust and allergens. It’s a great alternative to the traditional air conditioners, but is more effective and energy efficient.

The pump circulates water onto a cooling pad that absorbs the water and then the fan draws air from an outside unit through the moistened pad. As it passes through the pad, the air is cooled by evaporation, so you must make sure that the cooling pads are completely wet at all times during operation. Through evaporation, the added moisture keeps your skin from drying out and prevents any type of dangers from the heat. These units circulate the air from outside into your home helping to make the air fresh and clean.

Which Size Will Suit Me and My Home?

To determine the correct size of an evaporative cooler for your home, you need the cubic feet per minute (CFM). CFM gives the number of cubic feet of air an evaporative cooler can move in just one minute. The first step is to determine the cubic feet of space needed to be cooled, and then divide that number by two.

Formula: Square Feet * Ceiling Height = Cubic Feet

Cubic Feet / 2 = CFM

Example:

If you have a 1,600 sq. ft. room to cool and an 7 ft. ceiling, you should multiply them together, and then divide by two as such:

1600 * 7 = 11,200

11,200 / 2 = 5,600 CFM

You need a evaporative cooler rated at 5,600 CFM or higher.

Maintenance

Evaporative coolers require little maintenance with basic and proper cleanings. The pumps and pads should be cleaned and replaced at least once every 2-3 weeks in order to avoid mold and dirt buildup. This may depend on how long the cooler is operating. However, you will save yourself a ton of money by proper maintenance to increase the longevity of your unit. They are highly energy efficient and operate for way less money than a traditional air conditioner.
