The ONA Block is recommended for small areas requiring strong neutralisers to deal with unpleasant smells. The ONA Block measures 3 inches x 3 inches and performs extremely well in closets, grow tents, attics and any small, contained area! To use the ONA Block simply take the cap off the top and place it in your desired location, the fantastic odour neutralising formula will do the rest!
ONA Blocks are not fragrance dispensers, their formula actively destroys a wide spectrum of both organic and non-organic odour particles. This is why you can be sure ONA Blocks will take care of your odour problem and not just add to it!
We stock ONA Blocks in three different scents: Fresh Linen, Polar Crystal and PRO.
Please note: All ONA Blocks are the same dimensions: 3 x 3 Inches and 6oz.
