What Does a Portable Swamp Cooler Do?

Portable swamp coolers use water evaporation to absorb the hot air and release cool air. The temperature of the hot air can be decreased significantly with the help of water that is absorbing the heat. The water that absorbed the heat then turns into vapor, which is called evaporation. The device then releases the much cooler air that is also moisturized.

Swamp coolers are also called evaporative coolers, and sometimes they are called swamp boxes, desert coolers, and wet air coolers. They are becoming an increasingly popular option due to their energy efficiency, especially when compared to air conditioners.

Portable swamp coolers can be used to cool down the air indoors and outdoors equally as effectively. Swamp coolers can be the perfect solution for dry and hot areas, as they will decrease the air temperature as well as release humidity into the air through evaporation.

What are the Types of Portable Swamp Coolers?

Depending on the size and power of the swamp cooler, we can divide the swamp coolers into three general categories:

  • Portable indoor swamp coolers
  • Portable outdoor swamp coolers
  • Whole house or window-mounted swamp coolers

Portable Indoor Swamp Coolers

Portable indoor swamp coolers are the most common type of portable swamp coolers. These are made primarily for indoor use, and you can easily transport them within your home and use it in different rooms. If you have larger rooms inside your home, then you will want to purchase a swamp cooler with a higher CFM (Cubic feet per minute). The great news is that there is a wide variety of products in this regard.

Portable Outdoor Swamp Coolers

Portable outdoor swamp coolers tend to be much sturdier than their indoor counterparts. They are made to withstand the elements, and they are weatherproof, too. These devices are perfect for patios, gardens, pool areas, or other outdoor areas around your house. They can also be great for camping or for BBQ with friends.

Whole House Swamp Coolers

These devices are permanently installed into the window or onto the roof and will connect to your home’s water supply. They can become a great alternative for central air conditioning, especially for warm and dry areas. However, these swamp coolers are not portable.

How to Choose a Portable Swamp Cooler?

Choosing a portable swamp cooler can be simple if you know the ins and outs of the devices. There are several factors you need to consider that will make your decision much easier. These are the ones that matter the most:

  • Coverage area
  • Type of portable swamp cooler
  • Ease of use
  • Sizing and portability
  • Tank capacity
  • The climate you live in

Let’s take a closer look at each aspect of buying portable swamp coolers.

1. Coverage Area

Arguably the most important feature to consider when choosing portable swamp coolers is the coverage area of the cooler. It’s great to have a cooler that can cover larger areas. That’s especially the case if you’re looking for outdoor swamp coolers, where the coverage needs to be larger. But it’s also very important for indoor areas.

2. Type of Portable Swamp Cooler

Depending on your needs, you will want to choose the right type of portable swamp cooler. If you are looking for a cooler for your home, then an indoor portable swamp cooler might be best for you. If you are looking to cool in outdoor areas such as your garden, patio, or when you’re camping, then an outdoor portable swamp cooler is best.

3. Ease of Use

Is the cooler easy to use? Or is the usage complicated? One aspect of this is also how easy it is to maintain the cooler, and how often you will have to refill the tank. Also, how easy it is to do that, and what are some features that allow you to use the product with ease.

4. Sizing and Portability

These two aspects go hand-in-hand. The larger the swamp cooler is, the harder it will be to carry it around. Also, lighter coolers are also easier to take with you and are more portable. You will have to consider the sizing and the portability options when you’re choosing your portable swamp cooler.

5. Tank Capacity

Larger tank capacities can help you use the swamp cooler for longer without having to fill it up that often. However, you do compromise on portability slightly as larger capacities can also mean higher weights.

6. The Climate You Live In

Yes, this is also a factor to consider. Swamp coolers are great for warm and dry areas; if you live in an area that’s already humid, then swamp coolers might not be the best option, as they will emit humid air, increasing the air humidity around them.

How Effective are Swamp Coolers?

Swamp coolers are more effective than air conditioners. They will use only about 15-35 percent of all the electricity that air conditioners use, for example. That’s a great way to save money in the long-term.

Airflow in swamp coolers is controlled by opening and closing windows, as they will turn on and off automatically. Air conditioners, on the other hand, will use air ducts to move cool air into your home, demanding more energy to do that.

However, you do make some compromises with swamp coolers. Namely, they are not great for humid areas as they will emit humidity into the air. They can also cause mold to grow, which is something you will need to keep in mind when opting for a swamp cooler.
