When you live in a dry region, keeping cool can be challenging, and standard AC units may not cut it. The best evaporative cooler can solve that crisis as it does something an air conditioner can’t and is considerably cheaper to run.
If you’ve found yourself reading our guide, you’re planning on buying an evaporative cooler. Also known as swamp coolers, these machines lower temperatures by pulling in warm air and moisturizing it.
As air is pulled into the unit, it passes across pads soaked with water, which cools it before it’s blown back out by a fan.
This can drop the temperature in a room considerably depending on the size of the system and a few other essential factors.

The diminutive stature makes it an option for the best portable evaporative cooler, although it comes with a few drawbacks, as you’d expect.

Buyers Guide for Evaporative Cooler Fan
1. Cooling Area
Before buying an evaporative cooler, you should always read the cooling area specification written on the model description. This will allow you to know if the cooler you are buying is adequate for your space.
For instance, garages and workshops are considered larger, cooler areas; hence, they need air coolers to meet this need. While smaller or average-sized areas are regarded as low cooling areas.
It’s also important to remember that the cooling area of the swamp cooler you are buying should always be greater than or equal to the area you want to cool.
2. Cooling Pads
There are two types of cooling pads in the market.
- Honeycomb cooling pad: They are high density, made of cellulose, and resemble honeycomb in structure. They provide more cooling compared to other types of cooling pads. Honeycomb cooling pads are durable and highly efficient. The downside is that they are expensive.
- Aspen or wood/wool cooling pads: They resemble grass in structure and provide less cooling. They are affordable but less efficient and durable.
3. CFM And Square Footage
When considering the best evaporative coolers, there are two dimensions to pay attention to CFM: cubic feet per minute and square footage.
4. Water Tank Capacity And Indicator
As the size of your cooling area increases, so does your required water tank size. Selecting an evaporative cooler with an adequate tank capacity will prevent you from constantly having to refill the tank. Outdoor swamp coolers usually have garden hose hookup attachments.
The water level indicator notifies you of the amount of water present in the cooler. When it reaches the minimum level, the empty tank will inform you to refill the tank. This feature saves the swamp cooler from getting any damage on running water-free.
5. Air Swing Delivery System
This feature ensures the reach of air blows by the air cooler in all directions of the space. The swamp cooler comes with an oscillation of 40°, 70°, 120°, and as the degree of oscillation increases, the range of air blown also increases. This is an important feature to consider against the size of your room. As the bigger your space, the higher degree of oscillation you will need.
6. Speed Control
This feature allows you to control the flow of air you want by increasing or decreasing the fan’s speed. There are three speeds offered: Low, Medium, and High.
7. Extra Features
- Timer Function: A timer function allows you to program your swamp cooler for uninterrupted running, and once it reaches the set time, it will automatically go off. Swamp coolers come with a maximum timer function of 7.5 hours or 15 hours. Depending on your needs, you can select what works for you.
- Wheels at Base: Wheels allow ease of movement. Most evaporative coolers have four caster wheels making them easy to move around your indoor or outdoor space.
- Remote Control: This can be considered an extra feature but convenient. It allows you to control your evaporative cooler from a distance with the help of a remote.
8. Power Consumption
When considering buying an evaporative cooler, power consumption should always be top min. Though an evaporative cooler’s initial cost is one-off, the running cost concerning power consumption is a lifetime.
Hence, if you come across an eco-friendly evaporative cooler and consumes less power, that should always be one worth considering. However, this is also dependent on the size of the cooling area.
Frequently Asked Questions
1. How often do I need to replace the media pads?
Great question, but one that’s difficult to answer. It varies depending on how frequently you use the machine, along with the model and type of media used.
2. Do you need to leave a door or window open when using an evaporative cooler indoors?
Yes. To get the full effect, you’ll want a fresh supply of air coming into the area you need to be cooled, or humidity will increase.

Maintenance is low with these types of machines unless you have a whole-house evaporative cooler. Aside from changing media pads, you will need to drain the tank and clean the reservoir regularly to prevent bacteria.
4. Are portable evaporative coolers any good?
A Portable Evaporative Cooler can deliver a high level of cooling power in a highly effective way. Interestingly, it also consumes less energy while delivering unmatched cooling power. An Evaporative Cooler is a device that is also referred to by many as a swamp cooler.
5. How do I choose an evaporative cooler?
When choosing an evaporative cooler, look for the CFM – cubic feet per minute of air delivered to the house.
This will usually be in the range of 3000 to 25000, and depending on your climate, it’ll need to deliver 20 to 40 air changes per hour.
