The ONA Fruit Fusion 170 g block is a ready-to-use odour killer designed for indoor growing. Instead of layering perfume on top, ONA (Odour Neutralising Agent) technology binds and neutralises the odour molecules suspended in the air, leaving your grow space discreet and pleasantly fruity.

| Feature | Detail |
|---|---|
| Brand | ONA (Odour Neutralising Agent) |
| Format | Solid gel block |
| Size | 170 g |
| Fragrance | Fruit Fusion (fruity) |
| How it works | Neutralises odours, no masking |
| Use | Tent, grow room, extraction, indoor spaces |
| Indicative life | 4 to 8 weeks depending on airflow |
The ONA formula reacts with the molecules behind bad smells and neutralises them in the air, instead of simply covering them with a fragrance.
Peel off the seal and place the block in the area to treat: it slowly sublimates and releases the neutralising agent with no power and no maintenance.
A fresh fruity scent that leaves a clean, light atmosphere — ideal when discretion matters as much as performance.
On average 4 to 8 weeks. Real-world life depends on temperature and above all airflow: the more air moves, the faster the block works and the quicker it is used up.
Where should I place the block for best results?Position it near a moving airstream (air intake, fan or extraction outlet) rather than in a closed corner. Moving air carries the ONA agent and neutralises odours throughout the room.
Guaranteed discretion: cleaner air and a fresh Fruit Fusion note, without masking or overpowering your space.
