This is a great thing to clean up the air, I think it's Cypress where we worked out and they had one of them. Though it was took up a ton of space. But overall I loved it... =)
GMR Chalk Eater Air Filtration System Reviews
This is a really cool way to clean the air of all the chalk in the gym. We have one in our gym and it works really well. The only thing is it can get in the way especially if you don't have a lot of space.
