When I last looked, the evaporative methods were better than others. You don't need distilled water for it, tap will work. They do need cleaning and frequent disinfecting though due to the pad constantly sitting in the water. The prices of replacement pads are a bit expensive but it was cheaper than constantly buying distilled water.

There are a few brands out there but the Philips ones seemed better than the others and the prices were not as insane. I just disliked their marketing and buzzword filled content but otherwise they seem OK. Oh and you should know a lot of their stuff now are internet connected(disabling it will make you lose some functions but otherwise the device still works) and have touch buttons and screens etc. It's unfortunate but this seems to be where every device is heading.

I do agree with you that this seems overly complex. You can pretty much do it yourself if you'd like to take on a project. A fan and a constantly wet rag has the same function but is not as compact.
