ONA Blocks


* Required Fields


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.

Also consider using the ONA blocks in an ONA air filter within your ducting/air exchange system for maximum odour neutralisation.
