Hey, do you guys use any kind of system inside your homes to help with airborne toxins? Is there anyway to help clear the house of what comes in regarding the chemtrail toxins?

I know that some biologic dentists use extraction systems for mercury and I wonder if there is anything simlar you can use? Not that I"ve noticed their extraction systems help much, we're talking about a heavy metal here, even if it is vaporised and I still got poisoned after entering a dental office that was not only new, but had extraction system in place to help clear mercury vapor....

But I'd be interested to know if you guys have anything that helps with this? Or could think of something you could get put in that might help?
