Carpets can harbor toxicants and other gross stuff

I was reminded about carpets while hosting an open house today in Seattle at a LEED Platinum home that not coincidently has no carpets (you get LEED points for reducing or eliminating carpets, as they decrease Indoor Air Quality). Someone who came by today was quite pleased about the lack of carpet in the house, as he grew up in Mexico where carpet is uncommon.

Nice and cheap, cheap and easy, in and out in one day, and it’s foot traffic ready that same day.

There is one fact about carpet that the industry might wish you didn’t know, and it kind of sums up whats wrong with it in one quick tidbit: Carpet weighs twice as much when being removed from your house as it did the day it was installed. That should conjur up some pretty good images.

Everything you and your guests ever tracked in your home remains in the carpet, and can embed itself permanently deep in those lush fibers to the backing and in the pad too. Well, it’s just dust, no biggie. Did you ever wonder what dust actually is though? I recently attended a lecture by toxicologist Steven Gilbert, and what I learned is that dust contains:
