ONA Air Filter

Continuous odour control fitted straight into your ducting

The ONA Air Filter is an in-line housing that filters every bit of air leaving your grow room or tent, neutralising unwanted smells as the exhaust passes through ONA blocks before it vents outside. Attach it to your ventilation, load in the number of blocks you need, and odours are removed quickly, effectively and permanently, with a side access hatch so you never have to strip the ducting down to top up.

Key Benefits

• Whole-exhaust filtration: all air leaving the room passes directly through an ONA block, so nothing escapes untreated
• ONA block neutralising genuinely counteracts odour molecules rather than just masking them
• Side access hatch lets you add or swap blocks without dismantling your ventilation
• Scalable output: load more blocks for stronger control in heavily scented rooms
• Permanent in-line fitting for hands-off, continuous coverage

Odours slipping past your carbon filter?

Even a good extraction setup can leak residual grow-room smell at the vent, around door seals or when a carbon filter is past its best. The ONA Air Filter tackles that final stage, passing all exhaust air through active ONA blocks so lingering odours are neutralised before they reach the outside world.

How to Use

• Fit the filter in-line with your extraction ducting, downstream of the fan
• Load ONA blocks through the side hatch, adding more for stronger odour control
• Check the blocks periodically and top up or replace them as their scent fades
• Match the housing to your ducting diameter for a leak-free seal
