They will help protect their crews from airborne smoke particles while they sleep in their tents set up nearby active fires. #wildfiresmoke #airpurifier31 May 2026 20:51 +0000at://did:plc:h2bimymngnick7psij5lisnu/app.bsky.feed.post/3mn6gzmatec2thttps://bsky.app/profile/northboxsystems.bsky.social/post/3mmudumm3zc2fHere is our prototype activated carbon air cleaner.
