The reuseable aspect was one of my priorities when sorting out the Chez B face covering supply.
Good quality washable reuseable handkerchiefs and washable reuseable hair bands, and reuseable washable safety pins.
I also got a roll of v high quality filter media to insert - that isn't reuseable, but it is easily disposed of very responsibly.
Having said that, I hardly wear a mask at all, due to happily avoiding crowds, shops and the high street wherever possible (a habit that predates COVID). I don't see the point of wearing one on a dog walk, and simply back away when people come too close. If they follow me, I ask them to step back. They always look shocked, I mean, no one bothers with that nonsense any more, do they?
Mr B is supplied with good quality masks at work, and uses a lot of them, as per the regs for his role.
