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 dissapear, hallways and porches are a common use for this product, and the smell will be removed and replaced with the smell of the block.

Available in 5 different scents, we stock the biggest sellers Polar Cystal, Pro and Fresh Linen. Once you start using ONA you'll probably never stop, you just kinda get used to having the pleasent smell around.

Each block lasts around 4-6 weeks, they 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.
