Prem-i-air KY44B

It cools the office down a bit

Very noisy Drain hose / reservoir needs to be continually emptied (I leave hose in a 4 gallon bucket now !) Packing polystyrene is in unit which is blowing around inside with no means of escape

Powerful and quick

It's a biggie so beware of your size

Powerful cooling, powerful fan

Heavy unit; airborne water removal process can be swamped in high humidity resulting in on-board tank filling (though requiring only simple emptying)
