Abstract
A table-top air freshener has a tubular cylinder containing perfume-impregnated cellulose strips. The cylinder press-fits into a cylindrical cavity formed in a decorative housing with the bottom of the cylinder exposed for attachment to a stand. A selected length of the cylinder can be withdrawn from the cavity to provide a desired perfuming effect.
