Ona 170g Scented Blocks

Ona Block can be used as a stand-alone odour neutraliser. Ona Blocks are ideal for small areas such as closets, foyers, attics, cars, gym bags, boats, kitchens, garbage cans, cupboards or vents. These Blocks are 100% environmentally friendly therefore totally safe to use around plants, people and pets. Ona is a complex formula using essential oil plant based technology to destroy a wide spectrum of organic and non-organic odours. Unlike other similar products, Ona is not a masking agent, it neutralises odours instead. Simply open the lid and place in your desired location, preferably somewhere with a good air flow. Alternatively Ona Blocks are ideal for the Ona Air filter.

Available in scents: PRO, Fresh Linen, Polar Crystal, Tropics and Apple Crumble

Please note that we cannot guarantee which blocks are sent. If you have a particular scent you would like, please add a note to your order.
