I ordered one last time they were on sale. I got it through Casa.com for like $28 i think. less than $30. I am very happy with it. Been running it about 12 hours a day on max. Doesn't seem to really puff unless I turn it all the way up. No white mist. Super quiet. No mold yet. Cleaned with vinegar one time so far. Will prob do it again this weekend. Prob clean w vinegar 2x a month, might increase with age. Very happy with it.
