Ultra Beads, the commercial strength air freshener that attacks odor at the source for up to 90 days. Designed in an easy to hang bag, you can use Ultra Beads in stairwells, by dumpsters, in sewers, and anywhere else you need extra strength odor solution. Using Fresh's patented fragrance load, each bead is packed with fragrance for up to 90 days of freshness. Traditional Non-Para Super Block's are expensive, but Ultra Beads are just as effective and half the price.
