ONA Air Filters give the ultimate in growers peace of mind. They are used in conjunction with ONA blocks for the neutralisation of unwanted odours in your ducting.

The Ona Air Filter is an inline ducting chamber to hold Ona Blocks that helps get rid of odours from the grow room air extraction system. When you mount it inline, the air passes over the cage running through the centre of the fitting. By opening the access hatch, you can place your desired quantity of Ona Blocks inside.

Depending on the size you buy, you can get a few inside for more effect. Seal the blocks inside by closing the air-tight hatch and you’re good to go! The air coming out will be a pleasant fragrance which is far better than some of the other smells that can come out of a grow room! With a variety of Ona Block scents to choose from, you’re sure to find something you like.
