Description
Continuous odour control with no power or plumbing
ONA Block is a solid-gel odour neutraliser for the times carbon filtration alone isn't keeping a space smelling clean — drying rooms, workshops, bathrooms, or the corner of a tent room that always holds onto smell. Rather than masking odours, the ONA formula binds and breaks down the odour molecules themselves, and each block keeps working for weeks with no pumps, batteries or timers to manage.
Key Benefits
- Continuous action around the clock — just open and place, no power needed.
- Long-lasting: a single block keeps working for weeks before replacement.
- Genuine neutralisation that targets odour molecules directly rather than covering them.
- Choice of scents to match the room and the strength you want.
- No electrics or messy chemicals — a safe, low-maintenance backup for any grow or utility space.
Stubborn smells your filter can't catch?
Carbon filters handle extracted air, but lingering odours in drying rooms and surrounding spaces slip through. ONA Block sits in the room and neutralises odour molecules directly, giving continuous, discreet cover exactly where a filter can't reach.
How to Use
- Remove the lid and place the open block in the area you want to treat.
- Position it where air moves across it — near a fan or airflow — for the strongest effect.
- Leave the lid off throughout use and replace once the gel has fully evaporated, typically after a few weeks depending on room size and ventilation.
