Anyone who wants to have an air conditioner in their building should be very keen about what type it is that they need, as there are many kinds of air conditioners that are available in the market to choose from. You could go for a window unit, but one of its main disadvantages is that it would only be fit for servicing one room.

Another pick would be a mini-split AC unit, which would be best for when you’d want to be able to individually control the room temperature in each room, but they happen to be quite expensive. Going for a portable evaporative cooler would be best if you only want air conditioning in one room, and you’d like to be able to move it around, or hide it away when not in use. Some portable options include the Honeywell CO25AE and the Honeywell CO48PM.

In this case, the Honeywell 525-728CFM is potentially the best evaporative air conditioner you could get, especially if you don’t want to spend more than $300 on one. Read the rest of this review to find out why, and possibly compare it with other top-rated air conditioners.

Why We Like It – Honeywell 525-729CFM Evaporative Cooler

The Honeywell 525-729CFM Evaporative cooler is one of the best indoor outdoor evaporative air coolers in the market right now that guarantees that you’ll be able to enjoy cool air over any room or area that’s less than 325 square feet. To cool your entire house, you’ll want a central unit as you’ll find in our Goodman GSX13 review.

  • Very energy efficient
  • 7.5 Hour Programmable timer
  • Weather-resistant for outdoor use
  • Short programmable timer


An evaporative cooler, which is otherwise known as a swamp cooler, relies on the use of water-soaked pads to cool the air. It essentially works by a fan pulling in hot air into the unit, putting it through several pads to have it evaporate into a gas, and then having it blow out cooler than it was when it entered the unit. The Honeywell 525 CFM portable evaporative air cooler works in this exact way, and is built to cool large areas of up to 320 sq ft. This may be significantly smaller than the 950 square feet that the Hessaire MC37M portable evaporative cooler is capable of doing, but it is still one of the best Honeywell evaporative air coolers for indoor use. A more advanced model with a 3 in 1 functionality that you will love is the Honeywell 525-790CFM portable evaporative cooler.

Energy Efficiency

Evaporative coolers are known to use up to 80% less energy than a typical air conditioner would, making them perfect for anyone who is looking for an air conditioning solution that guarantees low power consumption. The reason for this is that it does not have a compressor, which is the main reason other air conditioners tend to use a lot of electricity to run. For the purpose of efficiency, another option is to go for a unit with a sleep function like the hOmeLabs 12,000 BTU Portable Air Conditioner. Also worthy of mentioning is that the Honeywell portable air cooler has an output rate of about 525 cubic feet per minute, making it almost half as powerful and efficient as the Hessaire MC18M, which has an airflow rating of 1300 CFM.


The Honeywell 525-729CFM indoor evaporative air cooler features a carbon dust filter that’s perfect for preventing any kind of air contaminants from getting through to the area that’s meant to be air-conditioned. The carbon element is specifically meant to get rid of the bad odor, to make sure that you get to enjoy a fresh breeze every time you have the AC unit on. You won’t find a carbon dust filter on the Luma Comfort EC111B, and neither will you find it on a lot of window air conditioners for that matter, making it very unique. 


Backing the Honeywell 525-729 indoor/outdoor cooler is a 1-year warranty on both parts and labor, so you shouldn’t really hesitate to contact the manufacturers if you find out that there’s a problem with your unit. It should always be able to produce a cool breeze whenever you have it switched on, and cover a cooling area of up to 320 square feet without any strain. This certainly categorizes it as a great outdoor air conditioner


The cooling effect that’s created through water evaporation is the only principle that the Honeywell 525-729CFM evaporative cooler relies on to create a comfortable environment for its users. The biggest advantage of this is energy efficiency, and this makes it much more reliable. The air cooler also comes with a remote control for more convenience when handling, an ice compartment that guarantees cool air, and also features a detachable water tank that’ll hold up to 7.9 gallons of water.

Honeywell 525-729CFM Evaporative Cooler Wrap Up

As a product that has received a lot of positive customer reviews, the Honeywell 525 CFM indoor/outdoor evaporative air cooler is one of the most reliable swamp coolers on the market. You’ll be able to use it outdoors since it’s weather-resistant, and with a timer that’s programmable for up to 7.5 hours, you can set and leave it to go about your business.
