So today I worked on an air purifier, now my idea is pretty simply an air purifier that is compact yet powerful and most importantly silent because I dont want to listen to a fan all the time, I first looked through some avalible air filter and some cool open source ones and I took inspiration for the deisign from Dieter Ram who is famous for making all kinds of really cool minimalistic stuff

The main parts:
3d printed case
True H13 Hepa Filters
small filter paper

I also plan to include an custom pcb which includes a pcb with a Temperature, Humdity, and VOC , I want to use an esp32 for its bluetooth and maybe make an app to control it remotely?(idk about this part)

I also want to have a small screen but I haven’t looked through this idea yet, becuase I want this to be really minimalistic and easy to use
