How to choose your Air Cooler?

Criterion 1: The area of ​​the room

Before buying a cooler, you should consider the size of the room where you plan to use it. Indeed, this criterion will determine the dimensions, the power and even the type of air cooler you will need. Depending on the size of the room, the season and the humidity, the more powerful models can lower the temperature by 4 to 6 ° C.

You may also buy a device to cool several rooms, including the living room, bedroom, office … In this case, the trick is to take into account the area of ​​the largest room to determine the size. device you need. So your air cooler will not lack power.

Criterion 2: Air flow

This is the volume of air circulated in 1 hour. The larger the room, the higher the air flow should be. To make your life easier, it is better to choose a cooler on which the air flow is easily adjustable. This allows it to be adapted to various conditions. A high-performance device must be able to offer a flow of 250 to 450 m³ / h with the possibility of varying the flow.

Criterion 3: The water tank

The larger the water tank, the longer the cooler can run. This criterion directly influences autonomy. For example, mini evaporative air coolers have a tank capacity between 400 and 1000 mL. This will require you to refuel often. Conversely, standard models can last 6 to 10 hours.

Determine the tank capacity you need for the largest room where you plan to install the air cooler. For home use, it should cap at 8 L. Also, make sure it is easy to refuel. Finally, be aware that many coolers are sold with ice packs for an ever cooler mist.

Criterion 4: The noise level

The noise caused by an air cooler matters a lot, especially if you plan to use your device overnight. Ideally, the device will need as little noise as possible so as not to interfere. However, you should know that a so-called silent cooler is either very compact or very expensive.

In this sense, there are many models of air coolers of all ranges that adapt very well to night use or in the workplace. For these devices, the average sound level should be between 30 and 35 dB. For models intended for larger living rooms, a level of 40 dB is acceptable.

Criterion 5: Energy consumption

The performance of an electrical device inevitably raises the question of energy consumption. The air cooler is no exception. And depending on the frequency of use, it is good to check the power in order to estimate the electric power consumption to ensure that the device remains economical enough.

Therefore, an air cooler for a small room should have a power of about 60 W. For high performance, suitable for a larger area, you can choose a model with a power of 100 W .

The different types of air coolers

Depending on the surface to be cooled and the air flow rate of the device, air coolers can be classified into 3 types: standard, mini and industrial models.

The standard Air Fresheners

This is the most widely used type. This is also the closest thing to a portable air conditioner, but much more ecological. Most often, the standard air cooler combines several functions: ionizer or air purifier, air humidifier, fan, air cooler, etc.

Suitable for an area of ​​20 to 50 m², the device is equipped with casters, which makes it easier to move around given the fairly large dimensions. You should also know that this type of cooler is easy to use and often offers excellent value for money.


  • Ideal for surfaces ranging from 20 to 50 m², or even a little more
  • Easy to adjust and move
  • Device much more ecological and less energy consuming than the air conditioner
  • Often combines many functions: humidifier, cooler, fan, air purifier, etc.


  • Cooling slightly below A / C despite ice packs
  • Some models cost as much as a portable air conditioner

Who is it for ?

To have fresh air without exploding electricity consumption, the standard air cooler is an excellent solution. More ecological than the mobile air conditioner, it is also a cheap alternative for almost similar performance.

The mini Air Cooler

The name of this type of device sums up its qualities. Lightweight and ultra compact, the mini air cooler can be moved easily and accompany you everywhere. You can even take it on a trip. Even camping enthusiasts will be delighted to have this portable model, also the cheapest on the market.

But as you might expect, the qualifier “mini” also sums up the shortcomings of this type of air cooler. Impossible to ignore the low capacity of the tank, which will force you to regularly refuel. Not to mention that you have to place the device nearby and orient it correctly for optimal efficiency.


  • Lightweight and compact to accompany you everywhere
  • Very interesting price for small budgets
  • Most are multifunctional: ventilator, air purifier, humidifier, cooler …
  • Some models come with cooler bags and can accommodate ice cubes


  • Cannot refresh an entire room, only a part
  • The device must be oriented towards the user for an ideal cooling
  • The capacity of the tank considerably limits the autonomy of the device

Who is it for ?

Some users do not necessarily need to cool the entire room, either because it costs too much or because they are looking for more mobility. If you are one of those, the cooler might be right for you. And it costs almost nothing!

The industrial Air Cooler

Unlike the 2 types mentioned above, the industrial air cooler is strongly discouraged in homes. They are mainly used in offices, factory workshops, stores and supermarkets, reception rooms… in short, buildings with surfaces of 100 m², or even much more.

Very energy intensive, this type of device is also expensive. Count more than 1000 $ for a low cost installation! However, the costs remain lower than those of an air conditioning. Finally, the industrial air cooler must be placed on the roof due to the vertical flow. This complicates maintenance work.


  • Indicated for offices, workshops, supermarkets, reception rooms …
  • Lower costs than industrial air conditioning
  • Ecological solution


  • Not suitable for homes: too expensive, too complicated …
  • Consumes much more energy than the other 2 types of air coolers
  • Very specialized product, therefore not sold everywhere

Who is it for ?

If you have a convenience store, workshop or offices to cool in the summer, this type of device will save you money, unlike air conditioners. However, the costs of acquisition, installation and maintenance are too high for domestic use.

Air cooler or air conditioner: a dilemma between cost and efficiency

The fan just moves the ambient air. This process quickly shows its limits in summer, not to mention the inconvenience caused by noise, dust and fine particles. For real freshness in hot seasons, you will need to use an air conditioner or evaporative air cooler.

Cooling power

The evaporative air cooler is very effective in cooling the dry and stale air. Thanks to their air circulation process, they can lower the temperature in a room or a house by 1 to 5 ° C. It should be noted, however, that air coolers do not work very well in climates with more than 60% humidity,

The air conditioner cools the air inside the house. It does this by sucking hot air and passing it over an evaporator coil cooled with R-22 or R-410A refrigerant gas. This process also removes some of the moisture from the air in the form of condensation. The drier, cooler air will then be returned throughout the room.

Energy consumption

The cooler consumes less energy to complete the cooling process. That means you’ll pay less over the life of the evaporative cooling unit, compared to an air conditioner of similar size and wattage. In some cases, these savings can reach 50%. Some brands even claim 75%!

Despite its efficiency, the air conditioner cannot compete with the cooler in terms of consumption. Air conditioning requires more energy than cooling the air by evaporation. Many air conditioners consume as much as 50 refrigerators  ! In addition, the refrigerant gases used contribute to the pollution of urban areas.

Investment and deployment costs

The last important point concerns the amount you will have to pay to acquire an air cooler or an air conditioner. Here again, the cooler is distinguished by a significantly cheaper price. In addition, the absence of refrigerant gas and evacuation pipe considerably facilitates its installation and maintenance.

Conversely, the air conditioner is often expensive. Count 800 to 3,000 $ for a powerful Japanese brand model. However, the lifespan of an air conditioner is substantially similar to that of an air cooler. And for the installation, you will often need to hire a professional. Not to mention the maintenance.

Why buy a good Air Cooler?


Unlike most air conditioning units, the air cooler is very easy to move. Many models have ergonomic wheels and handles. So you can lift, roll or pull the device as you see fit.

The format

Another important advantage of the air cooler is its size. The compact format offers significant space savings. For a standard model, the dimensions of the device are small enough to easily fit into a closet. There are even portable and lightweight models that can sit on a table or the dashboard of a vehicle.

Energy saving

Unlike the air conditioner, the air cooler is much more economical. Indeed, its low power consumption does not have too much of an impact on operating costs. Some portable models even have built-in batteries with great autonomy.

The price

Air fresheners offer a wide range of prices to suit all budgets. Thus, it is possible to equip yourself with a good device from 50 $. Depending on user needs and additional functions desired, the price can vary between 150 and 600 $. It costs less than an air conditioner while being much more efficient than a fan.

What is the price of an Air Cooler?

Entry-level air cooler.

For around 50 $, the manufacturers offer very practical mini air coolers for camping or placed on a piece of furniture for local cooling. For something bigger, you will have to pay 100 to 150 $. If you search well, you will find a great deal.

Mid-range air freshener.

From 150 to 250 $, you should find a device capable of cooling an average surface of 30 m². According to manufacturers, some mid-range models may be suitable for an area of ​​80 m². Of course, the price will depend on the versatility, the sound level and the brand.

High-end air freshener.

If you are looking for an ultra quiet but powerful cooler, you will need to opt for a high-end model. A Dyson or a De Longhi will cost 300 to 650 $. For areas larger than 80 m², you will probably need to choose an industrial cooler. Count at least 1,000 $ for this type of device.

The best brands of air fresheners

In our opinion, the best brand of air fresheners for most people in 2020 is:

Klarstein – This German brand produces small and large household appliances for everyday use. What all of its devices have in common is their price / quality ratio. If you don’t plan to invest more than 250 $ in an air cooler and still demand quality, consider Klarstein.

Here are the other brands we recommend. They offer, in our opinion, a slightly poorer quality / price ratio for most people, but they can be better for price ranges (entry-level, high-end,…) and specific needs.

Dyson – Everyone knows this brand for their bagless vacuums, hair dryers and air handlers. Dyson is also for its bladeless fan design and exorbitant prices. But if you are looking for a high-end, reliable and efficient cooler, you’ve come to the right place.

OneConcept – You would be amazed at the variety of household appliances that this brand offers! Like Klarstein, OneConcept manufactures a bit of everything: vacuum cleaner, food processor, boiler, fan, air conditioner, washing machine, air cooler … Its powerful Kingcool Frost Line will not leave you indifferent.

Taurus Alpatec – For 25 years, this French brand has been offering solutions for air treatment and water treatment. Fan, boiler, air conditioner, air purifier, etc., Taurus Alpatec certainly has a device capable of meeting your needs. Its Taurus Alpatec R 501 air cooler is an entry-level must.

Olimpia Splendid – The Italian brand is one of the world leaders in air conditioning, heating, air treatment and hydronic systems. The success of air conditioners without an outdoor unit has not been denied for decades. Its series of air fresheners named Peler should do the same.


Adequate ventilation in the room is the key to effective cooling.

Unlike air conditioners, air coolers work best in a well ventilated area. An incessant flow of air is required for these devices to function effectively. In addition, good ventilation is also necessary to remove humidity from the room.

Place your air freshener in front of the window.

Air coolers work on the principle of evaporative cooling. The faster the warm air enters, the faster it evaporates and the cooler the air will be. Always keep a window slightly open when using an air freshener. This maximizes the effect of cooling and helps the cooler to operate efficiently.

Clean the air cooler before using it.

Even when not in operation, the air freshener collects dust and pollen. It must be cleaned before use, in particular after a longer or shorter period of inactivity. In case they are really in bad condition, it is better to replace them. Also, make sure that the tank has no leaks.

Put a little ice in your device for optimal freshness.

We use air coolers after filling their water tank. It may be interesting to add ice to this water to have more freshness. Nowadays, some air coolers have dedicated ice compartments. As you add ice to the water, the pads get colder resulting in cooler air.


Which air cooler to choose?

In our opinion, the best air freshener for most people is the Klarstein Whirlwind. The Manwe mini cooler will please those looking for a portable and ultra compact model. The Dyson AM10 is probably the best high end cooler. As for the OneConcept Kingcool Frost Line, its phenomenal power makes it a very pleasant surprise. Especially at this price.

How to choose your air cooler?

Determine the area of ​​the largest room you want to cool. Air flow, water tank capacity and energy consumption should be sufficient for this area. Finally, the noise level is important in case of night use. But the quieter it is, the more expensive it is.

What are the different types of air fresheners?

Manufacturers decline their production according to 3 types of devices: standard air coolers, mini air coolers and industrial air coolers. The last type is mainly suitable for large surfaces such as offices, supermarkets, workshops, reception rooms, etc.

Should we prefer the air cooler to the air conditioner?

Yes and no. The air cooler costs less, is easier to maintain, is much more environmentally friendly and consumes much less energy than the air conditioner. It must be said that the latter consumes as much as 25 to 50 refrigerators! But for cooling power, wall air conditioner and mobile air conditioner are still superior to evaporative cooler. Compared to other types of air conditioners, the cooler stands the comparison.

How much does an air freshener cost?

For only 50 $, you could treat yourself to a mini air cooler. A standard model sells for between 100 and 650 $. And you will have to spend more than 1000 $ for an industrial air cooler.
