The Honeywell HL09CESWK Portable Air Conditioner is a stellar example of a well designed air conditioning unit that’s got everything you might need to make it ideal for you, especially if you’ve been looking for an air conditioner that you’d be able to place in a room that’s about 300 to 400 sq ft in size. This Honeywell portable air conditioner is also very compact in size, so if you no longer want to use it, it’ll be very easy to put in storage. If you’re an individual that spends most of your time travelling, you probably want to find out if it could be the best portable air conditioner for RV. Make sure you get to the end of this review for that answer.

Why We Like It – Honeywell HL09CESWK Portable Air Conditioner

The Honeywell HL09CESWK Portable Air Conditioner is pretty much a standard AC unit that’s got all the required features to supply you with all the cool air that you need, as long as you intend to place it in a room that’s a maximum of 400 square feet.

  • Energy saving sleep mode
  • Dual filtration system
  • 3 in 1 functionality
  • No check filter indicator


With a cooling capacity of about 9000 BTU, the Honeywell HL09CESWK portable air conditioner is best suited for being situated in a somewhat smaller space. It’s got 3 functionalities built into it, as it is an air conditioner, a fan and a dehumidifier all in one. The portable AC unit has a dehumidification capacity of up to 80 pints a day, making it vastly different from the Ontel Arctic Air Ultra evaporative cooler which has a built in humidification function.

Energy Efficiency

To keep energy consumption at a low, the Honeywell portable air conditioner includes a 24 hour timer that you should be able to use to decide exactly when you need to have it on or off. Also worth noting is that it also features a sleep mode, which is a feature that the Costway Portable Air Conditioner also has in store. Alternatively, you can also choose to use the lowest of the three fan speeds that the Honeywell HL09CESWK features, and in doing so, energy consumption would be fairly reduced to a minimum.


While most portable air conditioners only have a single filter, Honeywell portable air conditioners like the HL09CESWK 9000 BTU portable air conditioner features a dual filtration system, which filters the air to a level where it is twice as clean. The filters are pretty easy to clean, since all you’ll have to do is wash them under a faucet and they’d be good to go.


As far as durability is concerned, Honeywell is well known as a reliable manufacturer, so the build quality on most of their products should be beyond reproach. The HL09CESWK Honeywell Contempo series portable air conditioner also does come covered with a 1 year limited warranty, so if you come across any challenges with it, feel free to reach out to their customer care team and they’ll be happy to help.


To make sure that you’re all ready and set to begin using the Honeywell HLO9CESWK AC unit once you purchase it, it comes with a full set window kit that includes a window bracket, unlike the LG LP0817WSR 115v portable air conditioner which will require you to get these things separately. On top of that, a remote control is also included to ensure convenient operation.

Honeywell HL09CESWK Portable Air Conditioner Wrap Up

The Honeywell HL09CESWK is a good quality pick for anyone that needs to have an affordable air conditioning unit in their house, and anyone that also needs a compact option that they can easily store away.
