A Little Background


Parts of an evaporative cooler.

An evaporative cooler is a kind of air cooling device that is usually more portable and cheaper than an air conditioning unit. Not every person can afford to buy an A/C unit due to the operating and initial costs, which leads people to just use an electric fan instead, which is less effective.  Therefore, if you are on a tight budget and cannot afford an air conditioning unit, the evaporative cooler can be a more cost-effective solution.

Most of them can be used at home and even in office spaces. These can be small enough to fit into a desk so that you can get cooling action even at the comfort of your home or office desk without having to install a large unit on the ceiling or on the wall. These are also usually portable because some of them have wheels, eliminating the inconvenience of only having one room that is cooled down.

The coverage area of these cooling devices might not be as good as real A/C units, but they do the job for summer heat. They are a good in-between solution between A/C units and electric fans. If you want a similar cooling power from an A/C unit but do not want to spend too much money on the upfront cost and monthly bills, this evaporative cooler can be a great solution for you.


A/C units provide more power but are more expensive than evaporative coolers.

These cooling devices work by adding ice onto the reservoir and the use of evaporative technology generates cold air within a room or given space or area. The ice that melts is what makes this device very simple but effective.

It usually has less mess because of the design of the reservoir that keeps the device from leaking out the water and making it evaporate so that it will not spill over when ice has melted down.

In the summer season, it is important to cool down but not spend too much on your electric bill. These kinds of units are great solutions for summer escapades, for really hot weather and for office spaces that are saving up on A/C units. Therefore, if your home or work area needs a lot of cooling but you can’t afford an A/C unit, you can go for an evaporative cooler instead.

How we Picked

If you want to choose the best evaporative cooler out there, you should know about the following:

Capacity of ice or reservoir: the capacity can depend on how much power you need to cool down a room, the size of your room and how long you will be needing the device to run. For instance, if you work on a regular day shift, it should have a large reservoir so that you and your officemates can experience the cooling power for a very long time without having to refill the ice more frequently.

Effective power coverage area: this will depend on how long you intend to use the device and the size of your room. You should have a powerful one or a larger one if you intend to run it for a long time and for a large room. On the other hand, if you just need a desktop buddy at hand, you can just check out those less expensive and portable evaporative coolers out there that do the job just fine.

Ease of usage: you should also consider a unit that is very easy to operate and to adjust the settings on. Most will just have simple controls like you would on an air conditioning unit, except that the process could be simpler. Most will also have controls for the fan direction, which is also good if you want to direct the air in a specific position. Fan-only mode is present in some of these units.

Portability: a good advantage of an evaporative cooler over an A/C unit is that it is quite portable, usually with wheels or very small and travel-friendly. This advantage over the air conditioning unit is what you should definitely find on your cooling unit so that you will definitely find it much more convenient and maybe even cheaper in the overall cost.

Durability: you should know if the unit is durable enough to withstand many uses, especially if you will be operating it in really warm places like in tropical areas or in California and Texas. You should not compromise durability with a low price – pick one that is decently priced but will not get broken easily on its motor. Many cheaper ones are not very durable nowadays, so it is important to pick one that has a reputation for its motor.

Warranty and return policies: like with most appliances and home conveniences, you should check the warranty policy of the manufacturer to make sure that you know when and where you can return it, as well as the returning conditions of the product. Remember that customer satisfaction is greatly important, especially if you paid a lot for your item, such as a cooling appliance.

Q: What is Freon and why is it harmful?


Freon is more commonly used in cooling appliances like air conditioners.

A: Freon is a kind of chemical that can be identified as a household gas that can be harmful to the environment. Freon is also known as Difluorodichloromethane or CCl2F2 and can be used for fridge and freezer coolers and air conditioner coolers.

The use of an evaporative cooler does not require Freon because it only uses regular water or even ice to cool down the surroundings. This makes it more eco-friendly in the process of cooling your room or area.

Q: Is an evaporative cooler better than a wall mount fan?


A wall fan may be cheaper but could be less efficient in cooling.

A: There are certain pros and cons of this kind of cooling device over the wall mount fan. For instance:

  1. Wall mount fans are less efficient in cooling effect.
  2. Wall mount fans are cheaper than these cooling devices.
  3. An evaporative cooler can be better in terms of cooling effect.

Q: Should I buy an evaporative cooler that has an air purifying capability?

A: Yes, it is worth investing in this kind of cooling device if it has an air purifying capability, because it has the capability to purify the air and cool it at the same time. This device is usually less expensive than regular A/C units but it will be worth the investment to have an air purifying capability to help the air be protected from contaminants. This can be helpful for your loved ones.

Q: Can this kind of cooling device save more money than using an A/C unit?

A: Whether your cooling device can be able to save more money than using an A/C unit can depend on the following factors:

Size of your area This refers to the cubic meters or area of the room you intend to cool.
Climate in your area This refers to whether you have a really humid climate or a dry climate.
Kilowatt hour in your area Most countries have less expensive kilowatt hour prices but many are still in the problem of having an expensive electric bill, despite the efforts of saving energy.

Q: Why is this cooling device an eco-friendly process?

A: The main reasons why this cooling device is eco-friendly are the following:

No Freon There is no Freon used in the process because it is only using natural evaporation process that involves only water or ice.
Does not dry your air For those with problems of dry air with air conditioners, this evaporation process does not dry the air when you want to cool it down, making it more comfortable for those with irritation problems.
No need for keeping air flow With an air conditioning unit, you need to keep your doors and windows closed to keep yourself cool. With an evaporation system, you don’t need to do that because air flow is constant.

Q: How do I know the ideal cfm or air consumption needed for my room or area?

A: The formula to find out the ideal cfm or air consumption needed for your room or area would be the following:

CFM = A / 2

Wherein:

A = area of your room in length, width and height.

For instance, a room measures 13 x 14 x 15 feet. It would be something like this:

CFM = (13 x 14 x 15) / 2

= 2,730 / 2

= 1,365 cfm

This would be your ideal air consumption for this room.

Q: On what climate is this kind of cooling device best used for?

A: This cooling device works well if your area has a humidity level that is lower than 60 percent or 50 percent. This means that cooling devices like these work more effectively in desert areas like in Texas or even some parts of California. It will still work on certain humid areas but not as effectively as it would on somewhat dry and hot areas.

Q: How do you clean or disinfect your cooling device?

A: To make your cooling device clean again after some time of usage, you can do the following:

  1. Consult the user’s manual on how to clean the device.
  2. Try replacing the pads as recommended or at least after 1 year.
  3. Make a spray bottle using vinegar, purify oil, citrus bliss and optional essential oils.

Q: Is it okay to add ice to my evaporative cooler?


Some evaporative coolers can accept ice other than water.

A: Yes, it is okay to add ice to your cooling device. This is because many of these cooling machines do have the capability to process ice if they have really large reservoirs. If it really gets hot in your area and normal water may not be doing the job properly, you can potentially go for ice other than water to speed up the cooling process or intensify it.

Q: How often should I refill the cooling device?

A: You can be able to know when to refill the cooling device in its water reservoir by knowing the following:

  1. Know how frequent you use the cooling device on a daily or weekly basis.
  2. Determine what speed you frequently use on the cooling device.
  3. Know the capacity of the water reservoir in total.
  4. Identify the temperature indoors and outdoors.

Q: What is the average power consumption of this cooling device?

A: The power consumption of this cooling device, on the average, is about 193 watts. This can vary depending on the size of the cooling machine, the brand, the motor type and the speeds available. It can also vary depending on what the device is intended for – if it is for home use or for industrial use.

Q: is it possible to use bore water for this cooling device?

A: Bore water is a kind of water source that comes from underground. There are some evaporative coolers that might not accept bore water due to the presence of minerals that could potentially break some of the circuitry in the cooling device. It is best to ask the manufacturer first if the cooling device can accept bore water.

Q: If my area is highly humid, will an evaporative cooler still work?

A: Evaporative coolers will still work even if the temperature is highly humid. However, it will not work as effectively as it would on a dry desert in Texas. Most people resort to a swamp cooler instead of an evaporative cooler. However, it can be hard to distinguish both, because some manufacturers confuse swamp coolers with evaporative coolers, but they are different in terms of effect on humidity.

Wrapping It Up

Overall, the Arctic Cove 700 is our pick for the best evaporative cooler due to its easy to use remote control and its fan motor not being too noisy. It has a coverage area of 500 square feet, has a timer option, and you can add both ice and water to make the cooling power last longer.
