Off gasses

So we got a new mattress and bed delivered yesterday and the off gasses are horrid. I woke up today with a migraine and sore throat. We had the windows open and fan going for the day and only one open at night. Today the windows are back open and fan on blast. Does anyone know how to speed up the process? We have a mattress cover on it, so that’s supposed to help. I’m going to sprinkle baking soda on the carpet in hopes that it helps too. I’m so paranoid about breathing this poison in while pregnant.
