Overview

Remove foul odours naturally – use ONA Blocks. 


They don’t just mask odours - they neutralise odours using an essential oils based formula that seeks and destroys organic and non-organic odours, replacing it with your choice of scent.  


Simply remove the lid and let the active ONA ingredients evaporate and neutralise any odours they come into contact with, permanently and efficiently. It’s as easy as that.


Choice of Scents: Pro, Fresh Linen or Polar Crystal
• Strong essential oils based formula
Doesn’t just mask foul odours – it eliminates them
Reliable and long-lasting odour control
• Permanently removes even the most stubborn of smells
• Completely organic

The Science

Ona’s neutralising agent was first initiated over 25 years’ ago, when a scientist found that terpenes (found in essential oils) permanently remove foul odours by absorbing them.


Based on these findings, Ona was born. It uses essential oil technology (organic) to remove foul odours.


It was first developed for industrial use, to neutralise strong odours in sewage treatment plants, rendering plants and chemical plants.


Now, you can use it in your grow room.

How to Use

Ona Blocks are for use in small, enclosed areas. Simply remove the lid and place your block and place the tub anywhere near the entrance to your grow room or exhaust outlet
