Project Description

I don’t know if anybody else remembers this, but during covid there were a ton of people making CR Boxes – homemade air purifiers, built from spare parts during the lockdowns.

I found some cheap HEPA filters recently ($1 each…), so I decided to play around with building one. I’ve previously been playing around with cardboard building supplies for other projects, like gardening and aquarium ideas. So, this was a fun change of pace.

It works fairly well, but it needs a stronger fan. Either way, it was a really useful exercise!
