Bought 4 packs of these to my apartment, they smell really bad, my apartment went to non-breathable, i can't live in my house if these are on use. wouldn't recommend these to anyone who wants to breathe like normal human being. feel like i have asthma or some other problems with my lungs with these. 0/5. I have tried to get rid of the smells with soaking them in baking soda, and have tried 3 different air refreshers but still, in the mornings when i go to living room i have to open all doors and windows if i want to breath. thanks really much!
