Cool! How long did the project take, would you say?
BTW 82% indoor humidity is really high; usually over 60% humidity and you risk mold and mildew growth in localized moisture hotspots. Mold is terrible for air quality since the spores are biologically active, so they effect you more than just the raw PM2.5 numbers suggest. You may benefit greatly from adding a dehumidifier (placed in 'that room' or basement that's dank/musty), even if it only runs in wetter seasons.
You probably already discovered this, but cool mist/warm mist/ultrasonic humidifiers are extremely bad, effectively being purpose-built air pollution generators. I strongly recommend investing in a larger evaporative pad humidifier instead. See Tech Connections video.
For general AQI advice, it's hard to beat just adding an Airfanta 3Pro every 300 square feet with at least one per room (excluding bathrooms). Designed by an engineer, it has the best dollar-to-perf and noise-to-perf ratio of any air purifier thanks to using PC fans and balanced E11 filters[0][1]. The main downside is that some people think it looks nerdy, lol
For a sleek finished look, you could always mount the ePaper display behind a decorative photo frame of your choice, and fit the matte (the white area around the photo) to the screen size. It's roughly 2.5"x4.5", so a 4x6 frame which mattes to 3x5 should work. A local photo studio should do the custom matte cutting at a very reasonable cost, and (considering the supplies and practice needed) it's probably the best option for a one-off project.[2]
Also calculating the dew point should be a more stable measure of the air's water content over different temperatures. The first picture works out to a dew point of 23 degrees, assuming 82% humidity is accurate.
Not OP, but thanks for the comment! In my research for cleaner indoor air custom fan-mounted purifiers came up as a cheaper and much more effective alternative to commercial air purifiers, but I haven't seen the Airfanta before.
Regarding humidifiers, do you have any links for further reading on the pollution aspect? I assumed that the distilled water ones wouldn't pollute the air, but I'm now realising I haven't actually checked.
I guess that most of the humidifiers sold on e.g. Amazon are the types you mentioned, do you have any recommendations in terms of brands/models?
Unfortunately even if you only ever use distilled water, crud and dust build up over time, and even start to grow bacteria. Technically the user manuals on these units will typically say to clean them every "use" (ie every day if used continuously), but realistically nobody does that.
Just get an evaporative pad style that physically can't atomize crud into tiny air pollution particles, and then use a humidifier drops product to protect against crud.
If you are going to build this, if possible switch the DHT for a Sensirion SHT40, 41 or a similar one. They are way better, and unless you are sourcing from Aliexpress binned stuff, they are similarly priced.
