A WARNING ON PORTABLE ROOM AIR CONDITIONERS

For the people defending these, I'm not saying "they don't work" if the room is small enough. I'm simply saying they are an incredibly poor and inefficient design, and in this day and age should be WAY better. Even simple old window whangers for the last 30 years are designed better and more efficient than these, because they do not exhaust room air that the unit "just attempted to cool". And ......there ARE air to air portable units with dual hoses........and intake and exhaust.

I bet there is AT LEAST a solid 20-30% drop between a comparable window unit and one of these "exhausting" units

My neighbor paid the price. There HAS to be others, and if you google reviews of these, there is plenty of dissatisfaction.

..........Like one of these.........
