This cooler features a pad that filters down the dirt particles from the air which ensures that you are breathing natural and clean air.

Are you looking for a cooler with a modern design? Well, the Honeywell CS071AE Portable Evaporative Cooler could be a great catch for you. It has a design that will suit any modern house and the compact design makes it look classy.

Normally evaporative coolers work best in the southwest and Midwest region of the United States because the humidity level there is less than 50 percent. This Honeywell cooler is also no different, so it would be better if you use this cooler in those areas or in very dry climatic regions.

Moving on. This cooler is also portable but not as much as the Ontel AA-MC4 because the Ontel AA-MC4 is smaller than this one. However, this cooler features moving wheels on the bottom which will make it much easier for you to move the entire thing whenever you want.

This Costway evaporative air cooler has an impressive design. In white and black combination this cooler is sufficiently handsome to fit in any modern house, same as the Honeywell CS071AE.

We don’t see much difference in the Honeywell CS071AE and Costway evaporative cooler. Apart from having 4 wheels at the bottom, it has two handles on the side which makes it easy to lift the entire machine.

This cooler will lower the temperature by water evaporation. Unlike others, this cooler features a honeycomb pad to filter down the air. Moreover, these filters are removable and washable.

As the name suggests, it looks like a tower. You will find a bunch of coolers that come with a three-speed setting but this cooler comes with an 8-speed function. You can control the speed with both touch and remote.

This cooling fan comes with oscillation. Fans which doesn’t come with oscillation, we don’t know if you have ever noticed, they blow a huge amount of air in one direction which is quite irritating. Because that can blow off papers, pens, or light things.

Expectations of buying an evaporative cooler.

If you want to replace a standard AC with an evaporative cooler, then you are just wasting your money.

These appliances just blow cold air to keep the room moist and free from dryness. So, if you are living in a desert or very dry region, then you can complement this with an AC.

If you don’t use an AC, be realistic and know that these coolers will only cover a small area and suitable for a single person.

Evaporative Cooler Buying Guide.

1. Understand the instructions first

A lot depends on the installation process. Though it comes into play after you buy the cooler, you can gather information on installation before buying. Faulty installation and usage can result in leakage issues. Don’t hesitate to contact a professional or an experienced user to help you out if the instructions are unclear.

2. Durability and Portability

Look for units that are sturdy and require very little to no maintenance. Even if it cost you a little more, you will end up saving more in the long run.

Evaporative coolers are most effective when they are portable. Because you may need to move them from one room to another. Look for caster wheels at the bottom, compact design and carrying handles.

3. Variable Airflow Settings

Some coolers have variable airflow settings. These units are more versatile and help you adjust the airflow as you need. So, if the weather is not much dry, you can lower the setting.

4. Space coverage

Let’s face it. Evaporative coolers will only cover a very small area of your room. The best whole-house evaporative cooler will offer maximum coverage. This will help to enjoy the cooling effect along with your family.

You will also need to take the CFM ratings into consideration. Generally, for use at home, an evaporative cooler with 3000-8500 CFM is sufficient.

But if you are planning to use it in a large home or office, go with the one with 7000+ CFM ratings.

5. Silent operation

Most air coolers operate silently. However, some will make a beeping sound and others will operate silently. It will become a mandatory option if you are not a heavy sleeper.

6. Filters

Some models have filters. And others don’t have any filters. Filters will help to protect against germs and bacteria. If your chosen cooler has a filter, make sure it is washable.

7. Ease of installation.

If you are planning to install the evaporative cooler on your own, it’s best to go for the wall-mounted version.

These coolers need very little maintenance and are also cheaper. The downside is they blow less air than the rooftop versions.

If you are willing to spend extra on installation, rooftop evaporative coolers will keep your whole room cool. The downside is you will have to spend more on maintenance afterward.

8. Different versions of evaporative coolers.

Depending on your space and needs you can choose between any one of these 4 evaporative coolers:

Portable coolers- Portable evaporative coolers are for smaller rooms. If your room is anything between 300-400 square feet, these coolers will work great. The advantage is you can easily move them from one room to another.

Window mounted coolers- These are the evaporative coolers that fit into the window. They are generally used to cool the entire room.

Rooftop evaporative coolers- Rooftop mounted coolers are great for cooling your entire home. They are also known as down discharges because they push the air down to the home.

Wall Mounted or side discharge- These types of evaporative coolers are attached to the side of the building or to the wall inside.

9. Fiber pads vs Rigid Media pads.

You will need to decide whether you want to pay more upfront or end up paying more later on maintenance costs.

So, if you are on a tight budget, you can go for the fiber pads. These pads are cheaper but they need to be replaced quite often. Most fiber pads are either cellulose or synthetic.

If you don’t want to spend time and energy on maintenance, it’s better to get an evaporative cooler with rigid media pads. They cost more but at the same time last longer than the normal fiber pads.

Due to their extra thickness, they will keep your room cooler for longer.

How well do evaporative cooler works?

The evaporative coolers work perfectly fine when everything is on point. Both evaporative coolers and air conditioners do the same job, keeping the environment cool. But the difference between them is their operation.

Evaporate coolers function by soaking air through a damp pad which lowers the air temperature and they deliver humid air as the air absorbs the water during the filtering process.

On the other hand, air conditioners function by taking the humidity out of the room which delivers dry and cold air. Ac works best in an airtight room.

If we think overall, evaporative coolers are better. As they consume less energy, moisturize the air and they are highly portable. The evaporative cooler offers a bunch of benefits, discussed in the below section.

As we mentioned earlier, evaporative coolers offer some benefits which make them suitable for some people. We are breaking each advantage of evaporative coolers below, have a look.


Refrigerate coolers user some different chemicals which cause damage to the environment. Plus, this cooler makes the air dry. On the other hand, evaporative coolers are completely natural, no chemical and moreover, they moisturize the air.

Low Installation cost.

You’ll need to hire professionals in order to install a regular air conditioner which will cost you a good amount of money. Moreover, you might need to buy some tools separately. And when it comes down to evaporative coolers, you’ll need to spend very little compared to air conditioners. With minimal knowledge, you can do it all by yourself.

Low Maintenance.

Regular air conditioner requires high-maintenance such as, repairing the fan, blower, compressor, etc. Evaporative coolers, on the other hand, require less to no maintenance compared to regular conditioners.

Breath fresh air.

Here comes the best part. Evaporative coolers don’t use any kind of chemicals so they ensure that you are breathing fresh air. On the other hand, evaporative cooler soaks air through two damp pads which filter contaminants and prevents them from going into your lung.

Another importance of owning an evaporative cooler is, your home will feel lively because of the natural air smell that would be produced from these coolers.

How Do You Size an Evaporative Cooler?

This is actually a very important thing to pay attention right before you make a purchase decision. An oversized cooler will increase the humidity which could be quite irritating.

So you have to buy a cooler according to your room size (the entire area you want to cool with the cooler). We are going to show you the easiest way to get the right size for you.

All you have to do is a little math. Aren’t you good at math? Don’t worry we are here, note down your entire surface area you want to cool with the cooler and note the height of the room. Now multiply the surface size by the height and divide the result with 2.

For example, if your surface area is 2000 Square feet and the height of your room is 10 feet. If we multiply, it would be (2000 x 10) = 20000 and then divide it by 2 (20000 /2) = 10000. You’ll need a cooler of 10,000 CFM (Cubic feet per minute).

Isn’t it simple?
