I purchased $100 humidifier last year (https://www.amazon.com/gp/product/B013OLI792/). It is supposed to emit warm air and didn't, hence i got huge discount. Just now I took it out of closet for winter and the power will NOT come on. Doesn't matter what outlet. I tried all troubleshooting steps. It will cost more to send for repair to have it replaced by a refurbished one. Not to mention spending time that I don't have (see my other post on time management) I am upset and frustrated right now because I planned to do lot of things and I got so many useless, external distractions today. Just please, recommend a good humidifier that - emits warm air - for large room - water to be changed at most every 24 hours Right now we are managing with https://www.amazon.com/gp/product/B001FWXKTA/ Water needs to be changed every day, and it also needs to be cleaned with white vinegar every day. The previous humidifier that broke down did not require such time-consuming cleaning.
