This isn't due to the blind spot, but it is still pretty weird to experience! Here's some more info if you are curious: https://en.m.wikipedia.org/wiki/Averted_vision

That's not as bad as I was expecting, but yeah extra cost is annoying. Thanks for the info about this!

Thanks, I will definitely spend some time looking into those! I saw some information about an additive for the water, and a special cleaning solution you are supposed to use. Do you have to order those regularly to keep it clean and running well?

Could you explain how this humidifier/air purifier works? I've wondered about the possibility of an air purifier that uses water rather than a "screen" but haven't seen anything. My wife and I both have allergies, and our house gets really dry in the winter so one small appliance to deal with both issues sounds like a nice solution.
