heres the unit in action! lol

it might be worth noting that this unit blows out moist air, rather than dry air that you get with air-con.

i havent had any problems with humidity, i get a constant 50-60%

but if you live in a huimid climate it may be an issue. saying that though, power is ajustable, low medium, high so you can set it to what you need. i doubt youll get much more humid than ambient levels anyway, ive found that it barely increases humidity.
