What is a portable evaporative cooler?

A portable evaporative cooler, also known as a swamp cooler, is a device that uses evaporation to cool air. The device consists of a water reservoir, a fan, and a cooling pad. The fan draws in hot, dry air and passes it through the wet cooling pad. As the air passes through the pad, some of the water evaporates into the air, which in turn lowers the air temperature. Portable evaporative coolers are often used in areas where there is little or no natural humidity, such as deserts.

The price of an evaporative cooler will vary depending on its size and features, but they’re quite affordable compared to other cooling systems like air conditioners which tend to be much more expensive due to their high energy usage requirements (although they’re still cheaper than having an electrician come out and change out your wires so they run through your attic instead).


A portable evaporative cooler is made from a variety of materials, including metal and plastic. The material used in the construction of the unit can impact its durability, weight, and cost. Some units are designed for use in areas that may be exposed to moisture or rain (such as a patio or yard), while others are designed for indoor use such as a living room or bedroom.


The design of a portable evaporative cooler also impacts its durability, weight, and cost. Units with more than one fan blade tend to be more powerful than those with only one fan blade but they also tend to be heavier and more expensive than single-blade units. Some models include an additional hose port so that you can connect multiple hoses at once which provides additional cooling power, but this may also make the unit heavier than other models with fewer features.


A good warranty should last at least 2 years. A longer warranty is better, but it is not essential because evaporative coolers are generally very durable. The key thing to look for is that the warranty covers all parts of the product, including any labor costs if needed.


This is the ability of a cooler to take moisture out of the air. The higher the dehumidification rate, the drier air it will produce. If you are in an area where humidity is high or if your home has poor air circulation, then it’s important that you find a portable evaporative cooler with high dehumidification rates so that you can combat these issues effectively.


Portable evaporative coolers come in all shapes and sizes, but they can be divided into two groups: those with wheels and those without wheels. If you want to move the unit around your house easily, then look for one with wheels; otherwise, a non-wheeled model may be more suitable for your needs.

Power source

There are two common types of power sources for portable evaporative coolers: electricity and gas. Gas units are usually more expensive than electric, but they can also be more efficient and quieter than electric units, which can make them worth considering if you need a lot of cooling power or if you have a hard time hearing anything over the sound of your central air conditioner running all day long (as many people do).

The size of your evaporative cooler is crucial. If it’s too small, it won’t be able to cool the whole room. If it’s too big, it will take up valuable floor space in your house or office. If you’re not sure what size would work best for your needs, look at the coverage area and find out how much square footage it can cool in one hour. That will help you determine how much space it can cover before needing to be refilled with water.

Noise level

The noise level refers to how loud an evaporative cooler is while running. This information can also be found on manufacturer websites and should be taken into consideration when making your purchase decision because some people may find it annoying or distracting if they are using the machine while watching television or listening to music in another room.

Coverage area

Not only do you want to consider how much area an evaporative cooler can cover in one hour, but also how long it takes for the unit to cool down once turned off or emptied of water. Some units take up to 30 minutes before they reach their optimal cooling levels again after being turned off or emptied of water (depending on their size). This is something that should be factored into any decision about whether this type of cooling system would work well for your needs.

Control system

Different types of control systems have different features which may be suited to your needs. For example, some systems use timers for shutting off automatically at certain times while others allow users to manually turn them off when needed. Keep this in mind when shopping around for a new portable evaporative cooler because not all control systems are created equal!


Some brands are better than others, and some have more experience in making evaporative coolers. If you buy a cooler from a company that has been making them for years, you will likely get a better product than if you buy one from someone who just started making them and doesn’t have much experience.

You should consider whether your style and the style of your home match up with what is available on the market. If not, it may be worth waiting until another style comes out that meets both your needs and your desires.


The design of an evaporative cooler can make all the difference in whether it fits into your space and helps keep things cool enough without being too loud or difficult to clean up after use!

Customer Service

You want to make sure that there are plenty of customer service options available if you need them. This can include phone numbers, email addresses and even live chat support via a website or app. If there aren’t any phone numbers listed, then check out their social media pages – they should have some way of getting in touch with someone if necessary!

The pros and cons of portable evaporative cooler:


-Portable evaporative coolers are inexpensive and easy to move.

-They are energy-efficient and require little maintenance.

-They can be used in any location and at any time, even in places where there’s no electricity or water supply.


-Portable evaporative coolers can be noisy.

-They have a short lifespan, so you’ll have to replace them frequently.

-They don’t work as well in humid environments.

Types of portable evaporative cooler:

There are three types of portable evaporative coolers:

-Cool mist: These are the most common type of evaporative cooler, and they work by blowing air over water that has been sprayed into the air. The water evaporates, creating a cool mist that helps to cool down the surrounding area.

-Portable swamp cooler: These are similar in appearance to “traditional” swamp coolers, but they’re much smaller and more portable than their larger counterparts. They also don’t require any installation—you just set them up in an area where there’s plenty of ventilation, and they’ll do all of the work for you!

-Evaporative air cooler: This type of evaporative air cooler works by blowing air through a filter filled with charcoal granules that have been soaked in water. As the air blows over these wet granules, moisture is pulled out of them and into the surrounding space; this causes them to dry out very quickly so you don’t have to worry about mold growth like you would with regular swamp coolers (although it’s still a good idea to empty the unit and give it a thorough cleaning on a regular basis).

Common mistakes when using portable evaporative cooler:

  1. Not filling the water tank to its maximum capacity. This is because the reservoir will not be able to hold enough water and it will need to be refilled frequently, which will put a strain on your back and also waste water.
  2. Not using distilled or filtered water in your unit. This is because tap water contains minerals that can clog up the filter and make it less effective at cooling down your home or office.
  3. Not cleaning up after yourself when using the portable evaporative cooler; this includes cleaning out any dirt or debris from inside the unit as well as emptying out any remaining water from inside the tank when you’re done using it for the day/night/weekend etc., depending on how often you plan on using it!
  4. Using an extension cord with an outdoor appliance such as this one because it increases the risk for electrical shock or fire hazard due to overloading electrical circuits.
  5. Not having enough ventilation in the room where you’re using the unit; this could cause the unit to overheat and break down prematurely.
  6. Not reading through the user manual before using your cooler for the first time; this will help you understand how to properly operate and maintain your unit so that it lasts for many years to come!
  7. Not emptying out the water tank and refilling it with fresh water on a regular basis (at least once a week); this will keep bacteria from growing inside, which could eventually lead to health problems if you continue to use it without properly cleaning it first.
  8. Storing the portable evaporative cooler in an enclosed space such as a garage or shed; this could cause the unit to overheat and break down prematurely.
  9. Not using a cover for your unit when it’s not in use; this will help protect it from dust, dirt, and other debris that could otherwise get inside and clog up the filter or reduce its cooling efficiency.
  10. Using the portable evaporative cooler in an area that has high humidity; this could cause the unit to overheat and break down prematurely.

How to use portable evaporative cooler?

If you are interested in learning how to use a portable evaporative cooler, here are some tips that will help you get started:

  1. First, find out what size cooler will be best for your needs. There are smaller models that will fit nicely into small spaces and larger ones that can cool larger areas. Be sure that you choose one that is appropriate for the space where it will be used most often.
  2. Once you have determined what size cooler is right for your needs, pick out the model that best suits those requirements. You may want to consider purchasing a cooler with an automatic shut-off feature if it will be used in areas where children or pets might always meet it without supervision (for example). Also look at whether any additional accessories are included with your purchase – these can include everything from replacement filters to hoses that connect between multiple units so they can work together more efficiently!
  3. Read the manufacturer’s instructions carefully before using your evaporative cooler for the first time. This will help you understand how it works and what maintenance tasks will be necessary to keep it running properly. Many units require that the water reservoir be filled periodically, for example, while others may have self-contained reservoirs that only need to be refilled occasionally.
  4. Generally speaking, portable evaporative coolers work best in dry, arid climates – so if you live in an area with high humidity levels, you may want to consider another type of cooling system altogether. Many people find that these units do a great job of reducing indoor temperatures during the hottest months of the year!
  5. When using your evaporative cooler, be sure to open windows and doors in the room where it is located to allow for proper air circulation. Otherwise, the unit will not work as efficiently and may make the air inside your home feel more humid!
  6. Finally, remember that portable evaporative coolers are designed for temporary use – so don’t expect them to operate indefinitely without some form of maintenance. Be sure to follow the manufacturer’s recommendations for how often to clean or replace the filter pads, for example, and always empty out the water reservoir when it is no longer needed. With proper care, your evaporative cooler should last for many years!

FAQs about Best portable evaporative cooler

Do portable evaporative coolers need a window open?

Why do you need a window open with evaporative cooling?

Aside from the obvious benefit of keeping you cool; your windows should be left partially open to allow for fresh air ventilation. This will help keep dirt and dust out while also providing a better-quality living environment inside as evaporative cooling systems use outside forces like humidity or wind patterns in order recirculate indoor temperature levels instead!

How often does evaporative cooler dump water?

You should be aware that your evaporative coolers dump style drain valve will let water flow out every 6-12 hours and then again after it has been turned off. This helps to maintain the quality of this precious resource, which can also help stop any leaks from occurring if they do exist!
