If you live in an area where the weather there is always hot and humid, then life indoors can be very difficult if you don’t have a swamp cooler/evaporative cooler in your house. They’re the more energy-efficient alternative to popular air conditioners, and this is because they rely on the cooling effect that happens after water evaporation to produce cool air. The 525-790CFM Honeywell evaporative cooler could be a great one to start with if you’ve never really bought one before, and a serious option to consider if you’re looking around for the best windowless air conditioner. Go ahead and get to the end of this review to find out what it’s got in store.

Why We Like It – Honeywell 525-790CFM Portable

Anyone hoping to enjoy a nice cool breeze over the hot summer should really look into getting the Honeywell 525-790CFM portable evaporative cooler. It’s got an ice compartment for that extra chilly breeze, 3 fan speeds, and is capable of humidity control thanks to its dehumidifying function.

  • 3 in 1 functioning
  • Water level low alert
  • Active Carbon filter type for eliminating bad odors
  • No check filter indicator


As you might probably be able to tell, the Honeywell 525-790CFM has an airflow output capacity of about 790 cubic feet per minute, and is best for a floor area of 320 sq ft. This is similar to the Haier portable A/C. It’s also got 3 built-in functions, where it’s got a fan, a humidifier as well as a cooler. This is very much similar to the Whynter ARC-14S 14,000 BTU Dual Hose Portable Air Conditioner, as it also has those three functions, despite being fit for an area that is larger than that of the Honeywell 525-729CFM Evaporative Cooler. Also worth mentioning is that the Honeywell portable evaporative cooler has a decent-sized 7.9-gallon water tank, and it comes with a low water level alert so that you know exactly when you need to refill it.

Energy Efficiency

To make sure your energy consumption doesn’t spike once you purchase the Honeywell 525 portable evaporative air cooler, one thing that you can do is make use of its timer. The Honeywell MO08CESWK doesn’t have a timer, but it does have a handy remote. By using the timer on the 525, you’ll be able to program & schedule it to function at specific times, or even use less energy when doing so. A lot of evaporative coolers, like the Honeywell CO60PM evaporative air cooler, and air conditioners have this function, so it’s not really just unique to the Honeywell 525-790CFM. The Honeywell CO25AE for example also has a 7.5-hour programmable timer for lower power consumption. However, if you are a DIYer, you can always learn how to make a solar-powered air conditioner to try and save on some energy costs.


To keep the air that’s circulating in your room clean and free from any kind of unwanted bacteria, the Honeywell 525 indoor evaporative air cooler relies on a carbon dust filter. This filter is far better than the one that you’ll find on the serene life portable air conditioner because its carbon element helps get rid of any bad odors that might be present within the air, and in doing so, the portable air cooler keeps your air even fresher than a typical air conditioner would. Although, for a reusable, washable filter, you’ll want to check out the hOmelabs 14,000 BTU portable air conditioner.


Unlike air conditioners, evaporative air coolers don’t come with a compressor inside. This means there’s no huge risk over one particularly important part of a swamp cooler no longer working. This is why you’ll find that similar to most swamp coolers (like the Black + Decker BPACT08WT Portable Air Conditioner), the Honeywell 525-790CFM has a 1-year warranty backing it, that covers both parts and labor.


With evaporating cooling being accepted as a more energy-efficient alternative to air conditioners, air coolers such as the Honeywell 525-790CFM portable indoor outdoor unit are fast becoming the norm in a lot of households found in hot dry climates. The air cooler is fit mainly for indoor use, and comes with a remote control that you can use to adjust its settings at your convenience.
