Good Air™ odor eliminating fragrance contains a patented odor eliminating formula that neutralizes odor on contact, leaving nothing behind but clean, fresh air. As fragrance is diffused into the air, the beads will shrink. When all the beads have dissipated, it's time to replace with another jar. To use, just pull off the protective cover, replace with the decorative lid and notice the power of concentrated odor eliminating ingredients get right to work on tough odors. Use to battle strong odors or to freshen stale, musty areas for weeks. Perfect for the home, car, RV, office, lockers, pet "areas", bathrooms and closets.
