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

I'm not the first to say this, but essentially your body (specifically your immune system) doesn't know the difference (as far as how dangerous a sickness is) between a cold and ebola. So it always reacts very strongly to any "invader" that isn't part of your body normally. This is super simplified and I'm not an expert by any means, but here is a playlist of videos by a channel called Kurzgesagt with much more information: https://youtube.com/playlist?list=PLFs4vir_WsTyS2cy4vj4obl5igqCOV749

Or if you don't want to click on the link (or want to use a different device) you can search for Kurzgesagt and then look at their playlists; there is one with immune-related videos.

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.
