Air conditioners are no longer the expensive equipment that we all used to dread purchasing especially for a house or office that we happened to be moving into for the very first time. Nowadays, there are so many top top-tier air conditioners to choose from, depending on how much you’d like to spend on one. If the cheapest air conditioner remains out of your budget, you could also opt to go for an evaporative air cooler, and these are known to be more energy efficient in the long run. The Honeywell CO25AE indoor outdoor evaporative air cooler for example is a modern, reliable example of what you could go for if you’re dealing with a floor area of 300 sq ft. Does it have what it takes to be ranked as the best outdoor air conditioner? Let’s find out.

Why We Like It – Honeywell CO25AE

As perhaps one of the few evaporative air coolers that have got 4 different fan speeds instead of three, the Honeywell CO25AE evaporative air cooler is a premium option for anyone that would want an energy-efficient way of getting cool.

  • Water level low alert
  • Programmable 7.5 Hour Timer
  • 6.6 Large capacity water gallon tank
  • Expensive


The Honeywell CO25AE swamp cooler looks good, is weather-resistant, and guarantees a powerful airflow capacity of up to 500 Cubic Feet per Minute, pitting it side by side with the Luma Comfort EC110S. These attributes make it perfect for outdoor use, and on top of that, its oscillative louvres allow for air directional control. The unit is easily capable of a 9.3-yard air throw, and it also features a 6.6-gallon water tank, similar to the Honeywell 525-729CFM cooler, and it’s got a built-in low water alarm so that you get notified whenever the water level drops too low and needs topping up. For a unit that features a larger water tank, consider getting the Honeywell 525-790CFM which holds 7.9 gallons.

Energy Efficiency

Most air coolers score pretty high in regards to energy efficiency, as they are very well known for their low power consumption. This also rings true for the CO25AE Honeywell evaporative air cooler, as it’ll only require about 235 Watts to function. If this still isn’t low enough for you, then maybe the Newair portable air conditioner, at 80 Watts, may be a more viable option.


Aside from generating cool air as a result of water evaporation, evaporative air coolers also help keep the air fresh and clean, and this is done through the use of a dust filter. The filter does get dirty over time, and when it does, all it needs is a wash to get it back to optimum working condition. The filter in the Honeywell CO25AE indoor/outdoor evaporative air cooler is a mesh filter, which is the same type as that which you’ll also find in the Hessaire MC18M Portable evaporative cooler.


As is the norm with most portable air conditioners, the Honeywell CO25AE evaporative cooler is backed by a 1-year warranty, and it covers both parts and labour. Therefore, in case you have a problem with your new unit, don’t hesitate to contact Honeywell’s customer service desk.


The Honeywell CO25AE comes with a remote control to allow for a remote operation just like the Honeywell CO30XE Portable AC so you’ll be able to easily adjust its settings without getting off your couch. It has also got 4 fan speeds instead of the typical 3 options, and it features a top-loading ice compartment for a much cooler breeze. Users will also have some control over when the evaporative cooler will run thanks to its 7.5-hour timer.

Honeywell CO25AE Wrap Up

Evaporative air coolers are particularly meant for areas where there is low humidity. The Honeywell CO25AE would work best in areas where the humidity levels are less than 60%, making it a perfect source of air moisture. Have a look at some of its consumer reviews, and you’ll see that it remains a consumer favourite for anyone that’s a fan of evaporative cooling.
