If clunky window units are not an option, and swamp coolers don’t do enough to help you deal with the humidity in the air, then perhaps a portable air conditioner might be worth looking into. A portable air conditioner, like the Honeywell 525-790CFM portable unit, is so convenient to have since you can just roll it into any room that you want to cool down, and you’ll also be able to store away when you don’t need it. Does this sound like something you’d be interested in? Then perhaps the Honeywell MO08CESWK portable air conditioner might be of interest to you. Sit tight, and we’ll have a look at what it’s got to offer to see if it’s the best portable air conditioner and heater around, or if it ranks among the top-rated air conditioners on the market today.

Why We Like It – Honeywell MO08CESWK Compact Portable Air Conditioner

The Honeywell MO08CESWK Compact Portable Air conditioner is a mid-tier air conditioner that’s perfect for anyone that needs some fresh air in a small room. Like many air conditioners of its size, you’ll be able to roll it into any room you need to have it in, and even put it away when not in need. A similar light and compact AC unit is the Honeywell MO08CESWB portable air conditioner.

  • Bucketless operation
  • Removable & Washable filter
  • 24 Hour Timer
  • Only fit for small rooms


With a 10000 BTU rating, you’ll be able to warm up or cool down a room of up to 350 square feet in size, and with a dehumidification capacity of up to 41 pints per day, the Honeywell portable air conditioner will be able to efficiently drain the moisture out of the air. Granted, it’s not as efficient as the Whynter Portable Air Conditioner, but it does do pretty well for the price you’ll have to pay. The bucket-less design due to the auto-evaporating feature is a nice perk so you don’t have to empty buckets of water anymore, just like the design of the unit in our Friedrich P12B dual hose portable room air conditioner review. Its fan is only limited to two speeds, but it does come with a window bracket and exhaust hose required for installation, making it easier to put together. A more advanced model is the Honeywell MO10CESWK which has a dehumidification capacity of 61 pints per day, and a cooling coverage of 450 sq ft.

Energy Efficiency

In regards to energy efficiency, the Honeywell portable air conditioner doesn’t do too badly, as you’ll be able to control when and for how long you need it to run through its 10-hour sleep timer. The portable AC also features a smart humidistat, and this allows it to measure the amount of moisture in the air and regulate the amount of energy used to dehumidify it.


To help keep away any dust particles and clean up the air from harmful contaminants, the Honeywell compact portable air conditioner has filters within it that you can take out to wash, or also remove when they get worn out. This also applies to the LG LP1217GSR portable AC, and would be best to do after every 45 to 90 days of use.


Like most modern portable air conditioners, the Honeywell portable AC comes backed by a 1-year warranty that covers both parts and labor, so if you come across any issues with your recently purchased, compact portable air conditioner, then all you’ll need to do is contact one of their technicians, and they’ll be able to help sort out any problems.


Thanks to the remote control that comes with the Honeywell MO08CESWK AC unit, you won’t even need to get up to it to make any adjustments. Also, at between 50 and 55 decibels, it guarantees quiet operation just like the Newair Portable Air conditioner and heater does, which can be very handy if you have small kids in the house that need to sleep every now and then.

Honeywell MO08CESWK Compact Portable Air Conditioner Wrap Up

Available in either white or black, the 8000 BTU portable air conditioner is guaranteed to blend in perfectly with your interior decor. It’ll be able to easily control airflow through its front louvers, and since it’s got a timer, your electricity bill isn’t likely to go up after having it installed.
