    Dont waste your money ..get a split system!!!!


    I have had this 3.5kw mn series for about 6 week now ...seriously unimpressed with its cooling ability. I have the extremely hot plastic duct coming straight out and up to outside . have not extended it at all the cabin on my cruiser is 3 x 4 m it was 32 deg an hour ago best it ever does is drop the temp 3 or 4 degrees .. not good enough ..should have bought a split system... don't waste your money! it will cost some more but I now think its worth it...

    This air conditioning unit is very high quality and cools a room down very quickly. It is easy to install and uninstall making it a great pretty unit. It is not silent but the noise is easily tolerable. Dehumidifier also works quite well to get rid of moisture. Great air conditioning unit overall.

    Efficient and easy to install


    It is easy to install and efficient on reducing the heat in the bedroom, only down side is the noise from the cooling but was sort of expected from this kind of machine. The menu indicate you should consistently check if the water level in the machine is overflow but it never happen to me even I used it at least two nights a week for the last summer.

    Good working unit but too noisy


    Bought this unit on special from COSTCO. When it was in COSTCO displaying, we could not feel the noise level but once it is operating at home the noise level is significant. I would say sometimes is very hard to bear the noise.
    working to cool the room is not bad and definitely you will need a bucket for the water coming out. We were told by COSTCO staff that no water will be coming out. but I didn't believe it as it shows clearly on the back of the unit that water out tap is located. you will be amazed that how much water will come out.

    Overall, I think this is not suitable for home use as the noise level is too high but good for office or shop.

    GREAT product ever buy


    the cooling performance is quick.
    the portable unit look very minimalist yet modern, installation pretty easy but the air con hose not long enough because they only give you 1 meter.
    the unit are bit loud if you put it in the bedroom, but if you able to sleep with people talking around you that means this machine noice not gonna effect you.

    I was reluctant to buy a portable air-con after reading all the negative product reviews for all brands. Got a good price for this one, was assured it would cool one room (and one room only) and they were right. So far so good, it is great and has got me through this hot summer. Yes its noisy as it cuts in and out but you get used to the background noise. I like the look of it too. Can't move it up the stairs as its a bit heavy (tempted to get another for the bedroom) but so much easier and cheaper than getting a fixed air con in the wall.

    Honeywell MN10CES / MN12CES
    Is this a portable unit that can be moved from room to room
    What does it mean when people speak about window kits?

    2 answers

    Yes it can be moved from room to room. The window kit is used if you want to use the air conditioning function so it can push out hot air from the tube that’s connected to the window. I don’t use the window kit if I’m just using the fan function.

    Here’s a google image of what the window kit looks like when attached with the honeywell



    Thank you so much : )

    Will the window vent work with a window that opens out and only about 20cm?

    No. It'll only work with sliding windows.


    Yes it will if the hose fits bit you will have to block up the area around it with cardboard or plastic and it won't look pretty. If that doesn't worry you go for it.
