Re: Furniture off gassing
There is something called a "bake out". I learned this from a professional Indoor Air Quality consultant. Close off the room where the offending furniture is. Get the heat up in that room to 85-90 anyway you can (easier in summer weather). You can use portable heaters. The heat will accelerate off-gassing. Several times/day for 3d or more open windows and use fan to air room out well. Then close window and so on... This really works. Just make sure the room is shut off well from the rest of the house. We did this with a polyurethane floor and actually left the house for several days. Worth a try.
Also, when ordering items (blinds), be sure to let them know you are chemically sensitive and you expect the product to be completely cured.
