2-pack of scent refills for the D1000 dispenser. The two bars come joined with a perforation. Break them apart, and use one at a time, or use both if you want a stronger scent.
Also makes a great car air freshener — just place a bar under your car seat.
Note: Like all manufacturers, Aire-Master is going through challenges in our supply chain for raw materials. As a result, the scent bar material you receive might have a different color and texture than what is pictured above. The substitute material works just the same, it just looks and feels a bit different.
