 | Author: Jersey Chuck (San Franci.. | These scent refills last for maybe a week at most when running the unit 24/7. At over 3 & 1/2 bucks apiece they are not worth it at all.Get a Bounce (or similar) fabric softener sheet and fold it into a small square and insert it into the slot where the refill goes, about five cents ea.Potpourri or scented candle shavings wrapped in cheesecloth, Scented oil on a sponge (cut to fit) or a small piece of cloth with the oil will also do fine.Use your imagination and save your money! | 10 |
