Hang in there, MAG. I guess my New Year's Res. is to just keep chipping away at these things, one at a time, and create a healthy environment at least in my own home if not at work or out in the wide world. It's easy to get overwhelmed but keep ripping up that carpet. I ripped up the carpet in my office at work and it has improved air quality significantly! However, I work in an old house which is a satellite of our central office; if I worked there, nobody would have let me rip up the carpet.... Now at home I'll have to commit to cleaning a lot more often than I have done to date, as well as getting an air cleaner.
