The Honeywell HL09CESWK Portable Air Conditioner is a stellar example of a well designed air conditioning unit that\u2019s got everything you might need to make it ideal for you, especially if you\u2019ve been looking for an air conditioner that you\u2019d be able to place in a room that\u2019s 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\u2019ll be very easy to put in storage. If you\u2019re 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.\r\n\r\nWhy We Like It - Honeywell HL09CESWK Portable Air Conditioner\r\nThe Honeywell HL09CESWK Portable Air Conditioner is pretty much a standard AC unit that\u2019s 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\u2019s a maximum of 400 square feet.\r\n\r\nPerformance\r\nWith 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\u2019s 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.\r\nEnergy Efficiency\r\nTo 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.\r\nFiltration\r\nWhile 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\u2019ll have to do is wash them under a faucet and they\u2019d be good to go.\r\nDurability\r\nAs 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\u2019ll be happy to help.\r\nValue\r\nTo make sure that you\u2019re 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.\r\nHoneywell HL09CESWK Portable Air Conditioner Wrap Up\r\nThe 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.
