For the cost it is worth it to me to keep using them like once a week or so
Made a difference. The first time i put one through i found some dog hair and a marble. The marble through me because we have not had marbles for almost 3 years. Not sure where it was hiding but, it's out now. I don't notice there smell after I use them but, my system vents out side. For the cost it is worth it to me to keep using them like once a week or so.
