I am aware that carpets offgas. But this carpet smelled terribly toxic. It stunk up my entire basement. It took many hours with windows open long after the carpet was gone for the smell to leave. I placed it outside for a day to offgas and then put it in my garage. It stunk up my entire double garage. I returned it. If you are worried about dangerous VOCs, buy green label certified carpets, which Wayfair carries. It is what I will be doing from now on. I really wanted to love it.
