Ona Blocks are a simple way to get rid of unwanted smells naturally. Simply place the block in the area where you want smells to disappear, hallways and porches are a common use fo r this product, and the smell will be removed and replaced with the smell of the block. Available in 4 different scents with the biggest sellers being Pro and Fresh Linen. Once you start using ONA youll never stop, you just get used to having the pleasant smell around. Each block lasts around 4-6 weeks, can also be placed in ducting outlets but this will significantly reduce the lifespan of the block. For longer-lasting options see our ONA Gel page. Recommended.
