While targeted for healthcare, has anyone tried this PAPR for woodworking? Many significantly discounted new units are available on eBay. I just purchased one for $100 with free shipping. The system looks less durable than woodworking PAPRs and additional face protection will be needed, but I can see this being useful as a backup PAPR especially for sanding, bandsawing, chainsawing, etc. Again, proper head and eye protection will be required as the face shield looks flimsy but overall value appears excellent.
