Having a decent sized air conditioner in your house is one of the things that a lot of your visitors will come to appreciate especially if you live in a region that can easily be categorized as hot and humid. It’ll also be in your best interest to get an air conditioner that works both indoors and outdoors, but since there aren’t a lot of air conditioners that would fit this use case, your next best bet would be to go for an evaporative cooler. The Hessaire MC18M indoor outdoor fits this use case, so if you’re shopping around for the best outdoor air conditioner, then it should be among your top considerations.

Why We Like It – Hessaire MC18M Portable

The Hessaire MC18M Portable evaporative cooler is a great option to consider especially if you need an air conditioning solution that’s fit for both indoor and outdoor use. The Hessaire MC18M has up to 5 different cooling & fan modes, and an impressive airflow output capacity of about 1300 cubic feet per minute.

  • Has an impressive water tank capacity of 4.8 Gallons
  • Has a water hose for continuous water supply
  • Available in 3 colors
  • No sleep mode/energy saving mode


The Hessaire MC18M swamp cooler has got a decent coverage of up to 500 square feet, making it perfect for anyone who would want to enjoy a cool breeze over a large area during a hot summer day. Unlike the Luma Comfort EC110S, the Hessaire evaporative air cooler features a water tank that’s got a capacity of up to 4.8 gallons, which is enough to keep you cool and fresh for between 3 to 4 hours. You can also choose not to avoid having to refill the tank by connecting it to a standard hose, thereby ensuring a continuous water supply.

Energy Efficiency

Being an evaporative cooler, the Hessaire MC18M won’t take up too much of your electricity. It only requires electricity to power the fan, and in doing so, it’ll then be able to direct air towards the cooling media, causing the water in it to evaporate, resulting in a nice cooling effect. To make sure that your energy bill doesn’t get too high, the Hessaire MC18M has got 5 different operational modes that you can choose from, giving you more options than what you would get with the Honeywell CO60PM Evaporative Air Cooler .


Unlike the Newair Portable Air Conditioner, the Hessaire MC18M has a filter inside that prevents any unwanted materials from getting spread out. In doing so, your air is kept fresh and clean, and after the summer season, you’ll want to make sure that you run the cooler fan for only 30 minutes to dry it out before you store it.


The Hessaire MC18M portable air evaporative cooler is backed by a 1 year warranty, so if your unit happens to arrive with any pertinent issues, feel free to reach out to the team at Hessaire, and they’ll be glad to send a technician over to check it out. The 1 year warranty period is pretty common with both evaporative coolers and tower fans, though some of them do offer the opportunity to purchase an extended warranty if need be.


Similar to how most modern evaporative coolers & air conditioners are manufactured nowadays, you’ll have the convenience to operate the Hessaure MC18M from the comfort of your bed or your couch thanks to its remote control. The air cooler works great if you maintain it well, and with 4 heavy duty, smooth rolling casters at it’s base, you’ll find it very easy to move it around whenever you need to.

Hessaire MC18M Portable Wrap Up

The Hessaire MC18M evaporative cooler is great for anyone who wants to be able to enjoy both indoor and outdoor use, and with up to 5 cooling & fan modes to choose from, there’s more than enough choice for you to pick out the perfect mode for you.
