Updated they worked.
First of all these come in a thin black plastic bag inside a plastic mailer. There are no instructions included. After doing some research I found they need to be renewed approximately once a month in sunlight for 2 hours. So first I placed one in each room. Not that I had any glaring odors. I did have a bag of yarn that I was given that has the person's perfume scent on it that gives me asthma. Put the largest bag in with the open bag. No change. Going to put the whole set in with it and see if it helps but not holding my breath. The two with buttons and attached loops are my favorites. Updated: they totally worked in the yarn bag. I can now use the yarn.<br /><br />Be careful if you cut open the bag. I cut both bags.
