Best Rated Portable Evaporative Coolers for 2016

Are you looking for the most amazing deals on the best portable evaporative cooler models you can buy in 2016? I know a secret you'll want to know too but you'll need to read this page to find out what it is.

I believe I'm right in saying you want a means of keeping cool in the heat of summer but you don't like the high utility bills that you get when running air conditioning in your home or office space. Am I pretty close? Thought so!

A much more economical alternative to AC that will still give you all the cold air you desire in a portable, vent free package is the ever more popular evaporative cooling unit. It's the genre of products this website is not surprisingly highly focused on, after all.

Top Rated Free Standing Evaporative Cooler

Honeywell CL30XC Portable
Evaporative Air Cooler

In my experience over the last two years, certainly, the top model of the non-AC class of air cooler has consistently been the Honeywell CL30XC. This year it still beats all the other models in its class for sheer cooling power, capacity, ease of use and features as well as its incredible economy rating and low purchase price over comparable portable air conditioners and coolers without exhaust vents.

With its very generous 7.9 gallon water reservoir tank and high power evaporating system and fan making it capable of cooling an area of up to 320 square feet by as much as 25 degrees Fahrenheit, this model is simply the best I've ever used. Sure, there are cheaper models but they don't stand up to this baby for sheer cooling power and long term economy.

You can buy the CL30XC online from Amazon by clicking the image or link on the right and get a really great deal on price as well as their free shipping deal if you qualify (see the info on shipping when you visit the target product page by clicking on the image).

The Best of the Rest

Just to show I'm not totally biased toward the Honeywell ventless cooler, I will also recommend two additional highly rated evaporative coolers that come a close second to the above. They're both on sale at Amazon at surprisingly low prices considering their capabilities, so be my guest and check them out as well if you want to see what else is available to get the job of keeping you cool well and truly done!

Luma Comfort EC110S

You'll love this stylish compact portable cooler that can chill a room of up to 250 sq ft by as much as 25 degrees. With a 1.75 gall water tank, it's smaller and lighter than the other models. However don't let its small size fool you. It will provide several hours of continuous cooling before needing a refill. It comes with a convenient remote control and is easy to move around the place on its easy glide wheels. It represents great value for money, is cheap to run and looks distinctively chic.
Kuulaire PACKA43 350 CFM

This unit is slightly smaller than the Luma with a room cooling capability of up to 175 sq ft by 10-25 degrees. It has a good size water reservoir tank capacity of 4 gallons for long periods of cooling without needing a refill. It has an 8 hour programmable timer, remote control and is really easy to use. Highly portable and easy to move around makes this model perfect for smaller area cooling situations and costs just pennies per day to run!

Know Your Humidity Rating

To reiterate the most important factor about owning and using an evaporative or swamp cooler, you must have a relatively moderate to low humidity level in your area. These devices are NOT air conditioners and they will lose functionality when the humidity levels are high (above 60% is a ballpark figure).

If you live in a place that has high levels of humidity on average, please DO NOT BUY ONE because you may be disappointed. Unfortunately, the only effective way to cool your home or workplace when the humidity level is high is to opt for traditional air conditioning, even though it costs a lot more to run, with up to 20x the energy consumption of a comparable evaporative (swamp) cooler.

As I explained in another articles on this site, "What is a Swamp Cooler," these cooling devices work by chilling the air by evaporation. As more moisture is evaporated to produce cold air, the amount of moisture (humidity) rises in the room being cooled until it reaches saturation point.

When that point is reached, the effectiveness of the process is greatly reduced as the air simply cannot hold more moisture (reaching 100% humidity). For that reason, you need to keep a window open to allow air from outside to circulate and carry excess moisture out of the room.

This works perfectly well when the ambient humidity outside is low enough to absorb the additional moisture created by the evaporation process in the cooler. But if that ambient humidity is very high, the air is saturated and will not assist in keeping you cool.

Of course if you're lucky enough to live in an area with low to moderate humidity, you can take advantage of the low energy consumption and high output of these innovative air chilling machines. Go right ahead and buy one and enjoy the healthy cooling capability combined with low energy bills that these give you over conventional portable air conditioners and they don't need venting or an exhaust hose either!


  1. Great review. I've been looking at alternatives to my old energy hungry AC system that is way too large for my condo and keeps breaking down. With the summer not far off, I was looking at getting two or three portable ACs but after reading this I realize it would be better to go for two or three free standing swamp coolers. I live in a really low humidity area that has hot days and cooler nights in summer. If these things can drop the daytime temp by 20 or so, its all I need. Thanks!

  2. I have searched everywhere, but cannot find an answer to this question. How long will the cool water or ice/water combination in the generous 7.9 gal reservoir last? If I have to leave this unit on to cool my pets while I'm gone can I leave it on (in evaporative cooling mode) without the risk of the unit burning out because the reservoir has gone dry? Surely this must have been tested at some point - at least as it relates to safety.

    Thank you.

  3. Martin, I guess you don't really know how these units work--they won't burn out if they run out of water, they just keep running as a normal fan when they dry out so there's nothing to worry about!

    Water usage times can vary. There's an adjustment for how much water will be released and depends on how humid it is in your area. I have my cooler set for max water flow as I live in an area that's hot and very dry. It runs for about 12 hours while I'm out at work without refilling and there's some water still left in the tank when I get home. There is an auto-shutoff timer you can set via the remote too.

    Hope that helps ya!
