I'm looking to purchase I guess a respirator soon, because while I don't break down anything too toxic yet, I feel like it's a good investment for when I start cutting into stuff or tearing out boards, etc, etc. Just a smart thing to do. Thing is, I have no idea what kind of respirator (is that the right thing even? ) to buy. I want something that's a decent quality, not disposable, one with replacement filters, nothing special. Can any of the members of the Scrap Metal Forum here provide some advice? I did a quick search and nothing really caught my eye.
