The ONA Block is an odour neutraliser in solid wax form. It is a complex formula of essential oils – industrial strength yet safe for home and business, and can be used around people, pets and plants. ONA blocks are a fast and easy way to fight against odours at their source in small sized areas.
Simply open and expose to the air or remove the block from its container. The lifetime of the ONA block will vary but it will be effective for about 4 weeks relative to the airflow and environment around the block.
