The ONA Air Filter provides complete, continuous odour neutralisation for your indoor growing environment. Attach it directly to your ventilation ducting, load it with ONA Blocks, and any unwanted odours passing through your exhaust are permanently eliminated – not masked.

Key Benefits

  • Continuous passive odour control – no electricity required
  • Works with your existing extraction system
  • Metal lid with rubber seal for an airtight fit
  • Quick-release catches for easy block replacement
  • Blocks are fully replenishable when exhausted

Compatible Duct Sizes

Available in 4", 6", 8", 10", and 12" diameters to suit most hydroponics extraction setups.

How to Use

Attach the ONA Air Filter to your ventilation ducting. Insert the desired number of ONA Blocks into the internal mesh tube. As air passes through, odours are neutralised. When blocks are exhausted, open the lid and replenish. ONA Blocks sold separately.
