Build your own Powered Air Respirator

When you're building the solarpunk future, it's possible you might spend hours in the workshop. If you need a PPE solution for airborne contaminants - consider building your own powered air respirator (PAPRa). You can build this PAPRa for less than $200 in parts. Originally created during the pandemic when supply chain issues made it difficult to acquire these devices. Wearing a PAPRa is more comfortable and safer than wearing an N95.
