ONA Block 170g – Solid Odour Neutraliser for Small Spaces & Air Filters

ONA Block is a solid odour neutraliser designed for small spaces and continuous passive odour control. Using a complex formula of essential oil plant-based technology, it destroys a wide spectrum of organic and non-organic odours rather than masking them. Simply open the lid and place in a well-ventilated spot – or use inside an ONA Air Filter for ducting odour control.

Key Benefits

• Neutralises odours – not a masking agent
• 100% environmentally friendly – safe around plants, people, and pets
• Works stand-alone or with ONA Air Filters
• Adjustable strength – expose more or less surface area to control intensity
• Ideal for small areas: closets, cars, kitchens, gym bags, grow tents, and more

Available Fragrances

PRO, Fresh Linen, Polar Crystal, Apple Crumble, Fruit Fusion, Tropics, and Lemon Grass.

How to Use

Remove the cap and place in your desired location, preferably with good airflow. To regulate strength, punch small holes in the cap and replace it – more holes means more odour control. Compatible with ONA Air Filters (sold separately).
