Ona block

The ONA Block is ideal for small areas such as closets, foyers, attics, cars, gym bags, boats, kitchens, garbage cans, cupboards or vents. Simply remove the cap, or punch several small holes in the cap and place in desired location. The ONA Block measures 3" x 3" and will fit in most places.

The ONA Block will release its powerful odor neutralizing agent and keep the location free from undesirable odors. Replace as necessary.

Available in our popular scents: Fresh Linen, Polar Crystal, and now in the incredible new ONA PRO. This amazing new formulation has been well received by our customers and they are constantly finding new uses for the ONA Block.
