Hospitals
What do they use ? Dirt belching shake out bags ? Paper bags, or a central vacuum system ? I know one thing : I don't want particles from a dried out rubber mat in my lungs, or fiberglass particles thrown into the air, and settling onto the surface of my eyes, mouth and sinuses. If the shake out bags prevent that, I am fine with them. But if it can be shown that a HEPA, or any other paper filter can catch those micro nasties, I am open to that, too. I like scientific studies. We have a lot more toxins to contend with in certain parts of the world, now.
