Evaporative cooler is the affordable alternative to air conditioner, especially in dry and semi-arid areas (with less than 40% humidity levels).
They use evaporation method to decrease the temperature by up to 15 degrees. When compared to air conditioners, they consume less power. And moreover, they can be used both indoors and outdoors.
If evaporative cooler is your choice, then consider the below factors while making the purchase…
1. Cooling Area
It refers to the volume of cool air delivered by the evaporative cooler. You should consider room size while analyzing this factor.
- For a small area – Invest in low CFM model as higher range will make the air muggy & humid and uncomfortable.
- For larger hall/workshops – Go for a cooler with a large CFM rating. Lesser CFM rating will not be adequate to cool the air.
- For outdoors – look for a cooler with airflow of at least 1000 CFM.
2. Water Tank Capacity
To prevent constant refilling of the tank, you have to choose a cooler with an adequate water tank capacity. For a complete working of all the night/day, it should have a tank capacity of at least 5 gallons of water.

How to Choose an Evaporative Air Cooler?
There are several factors to consider while shopping for evaporative air coolers. Below, we have listed all the essential factors, which you have to check and differentiate between various models to pick the right one, as per your requirement.
1. Cooling Area (CFM):
The size of the cooler/cooling area is essential to consider while buying an evaporative cooler. This will let you know whether the cooler can effectively cool the room or not. For this, you have to check the CFM of the cooler. Just like AC sized in BTUs, evaporative air coolers are sized in Cubic Feet per Minute (CFM). This describes how much volume of air a particular cooler process.
- If you brought a cooler that is too small for your room, then it works just more than a fan.
- If purchasing a cooler that is big/large for the room, it makes the air humid and uncomfortable.
- A swamp cooler with a high CFM will make pass more air through it. Thus, cool down the room/space quickly and thereby easily handle a large room.
Here is the formula used to calculate the right CFM, based on your room size.
Simply, multiply the room’s square footage with its ceiling height, and then divide it by two to get the right CFM for your room. For instance, searching for a cooler to use in a room with a 300 Sq. Ft & a standard 8Ft ceiling, then the right cooler size will be 300 X 8 /2 = 1200 CFM.
Also, remember that you should not be strict with this CFM rating. So, you can choose a cooler with 500 – 800 CFM for a room of 300 sq. ft. rather than 1200 CFM. But this less CFM will slowly cool down the room. When once your room cools down, then it will maintain the temperature easily.
Still, not sure about the cooler’s size, then check the product, as the manufacture suggest the maximum CFM a cooler can cool the room/space.
Want to use evaporative coolers for the outdoors, then purchase a powerful CFM rating (airflow at least 1000 CFM) cooler to cool a large space. Also, it’s best to choose the one designed with water and UV resistant to withstand any element or temperature.
2. Water Tank Capacity:
Are you tired of refilling the water tank constantly in an evaporative cooler? Then simply opt for coolers having adequate water tank capacity. For instance, a tank capacity of at least 5 gallons of water will be enough to run a swamp cooler all night/day. While a smaller tank with 1 – 3 gallons of water will last for 5 – 7 hours. A cooler utilizes the water from the tank based on its CFM.
Most outdoor models offer hose attachments that can refill themselves instead of manual filling of the tank. While indoor models, you need to refill the water to top off the tank eventually.
3. Cooling Pads:
In general, the cooling pads get wet in cold water, which allows them to absorb heat easily from the air and thus deliver a cool breeze. There are two types of cooling pads available in the market – Honeycomb cooling pad and aspen/wool cooling pads. Let’s know about them in detail.
Honeycomb Cooling Pad – These high-density cooling pads are made of cellulose, which resembles honeycomb in structure. They provide more cooling compared to other types of cooling pads. These are durable and highly efficient. The only drawback is that they are expensive.
Aspen or Wood/Wool Cooling Pad – This type of cooling pad resemble grass in structure. This makes it provide a less cooling effect. Since they are less durable and efficient, they are affordable.
Also, consider how often you need to replace these cooling pads, as some of the more exotic options are pricier.
4. Power Consumption:
Buying an evaporative air cooler is a one-time investment, but its running cost will be a lifetime expenditure, which matters a lot. In case, if you come across two similar features of air coolers but with different power ratings, then pick the one that consumes less power, irrespective of their prices.
The amount of area you want to cool will decide the power consumption of a particular model. A general rule is – the power consumption of a cooler will increase when there is an increase in its cooling area.
The cooler that is easy to mobile and portable are considered the best swamp coolers. They come with wheels and a lightweight yet sturdy body. Most of these models can be used to handle a single room at a time, which makes portability as a must option for these coolers.
6. Humidity Levels:
As we already mentioned, evaporative air coolers add moisture to the air and thereby meant to use in hot and dry areas. If using a cooler in a humid area, then it raises the moisture levels beyond the safety level. Thereby results in the development of mold in your home.
Most experts say that areas with less than 60% humidity are suitable to use an evaporative cooler. So, check out the moisture level in your space before buying an evaporative cooler.
7. Decibel Level:
The noise level of any item is measured in terms of decibels (dBA). While running an evaporative cooler outdoors won’t let you consider this decibel rating, but when you’re running a cooler indoors (or) looking for a smaller unit, then it is a must to consider this dBA level.
It is essential to know how loud your cooler will sound while operating and to know whether it disturbs your sleep or not. For instance, a vacuum cleaner is around 70dBA and a fridge can be at 50dBA.
8. Other Features:
Here are a few additional features that aids in the smart functioning of this swamp cooler. Have a look at them.
Speed Control – This lets you control the airflow of the fan’s speed, as per your requirement (either to increase or decrease). In general, there are 3-speed levels offered – Low, Medium and High. Set the speed level as needed to make yourself cool and comfortable.
Remote Control – With this convenient and comfortable feature, you can easily control the evaporative cooler from a distance by using the remote.
Air Filtration – Choosing a cooler with added air filtration will prevent allergen particles like pollen or dust or other debris, while cooling your space. A few models offer activated carbon filters for odor filtration.
ABS Plastic – Pick a durable model made with ABS plastic for a heavy-duty cooling effect, especially in industrial spaces.
Continuous Use – An evaporative cooler having a hose hook up will let you use it continuously. Simply, connect the hose for the cool air till you space is cool and comfortable.
Wheels at Base – The cooler with 4 caster wheels will make them easy to move around (ease of movement) in either indoor or outdoor areas.
Garden Hose Adapter – It is not fun to refill the tank after every few hours. If you’re tired due to this refilling water tank, then look for a swamp cooler with a garden hose adapter. This adapter will let you connect the hose to have a constant water supply.
9. Air Swing Delivery System:
This feature will ensure the reach of air blown by a cooler in all directions of the room. Here the swamp cooler has oscillation louvers of 40°, 70°, or 120°. As the degree of oscillation increases, the range of air blown will also increase.
To determine the proper air swing delivery system, you have to consider the size of your room. The bigger the space, the higher degree of oscillation required. If you want to cool down a large area/room, then purchase a cooler with a higher degree of oscillation.
10. Timer Function:
With this timer function, you can easily program the cooler for uninterrupted working for a certain period of time. When once the set time reaches, the cooler will switch off automatically. The coolers offer a maximum timer function of 15 hours with 1hr/2hr/3hr/4hr switch buttons. Also, remember that coolers with this option are a bit expensive. All you need is to select the time as per your requirement.
11. Water Level Indicator:
This water level indicator will let you know the amount of water present in the cooler. If water reaches a minimum level, then this indicator will notify you with a sound (alarm) and light to refill the empty tank. Thus, this simple gauge will save the swamp cooler from not getting any damage due to less/no water in the tank.
The price of evaporative coolers is affordable than ACs. Its price range will be from $. Make sure to choose the model that comes with decent quality and essential features, which comes within your budget range.
Most of these evaporative coolers offer short guarantees. Since they won’t have many moving parts, yet there are a few things that can leak, break or rust. So, look for a product the comes with an effective warranty period.
How does an evaporative cooler will work to cool the room?
An evaporative cooler will cool the room with the process of evaporation. They work by pulling the dry, stale air and move this air through a water-moistened cooling pad. Then the cool water gets evaporated into the air. Thus, this released cool air will be re-circulated back into the environment by using a powerful, and efficient fan.
Finally, this re-circulated cool air will produce a cool, gentle breeze that reduces the air temperature. The daily operating cost of this cooling solution will be up to 75% lower (affordable) than ACs. But remember that while using these coolers indoors, they should have access to a constant supply of fresh air either from an open door or window.
How to Maintain an Evaporative Air Cooler?

Frequently Asked Questions:
Ans: These coolers lower your room temperature by pulling the warm air into it. Here the pulled air passes through water-soaked filter pads and thus cools it before blowing out by a fan. This results in temperature dropping. With this continuous process, your room will get cooled down quickly. All you need is to check and refill the water for its continuous usage.
Ans: Evaporative air coolers work by combining the steady breeze with a natural cooling property of water to lower indoor temperatures. A slight difference between these coolers and ACs are the coolers will add humidity to the air and AC units will remove (dries it out). So, these two should not be used at a time.
