Anti-Odor ONA Block Duct Adapter 

This meshed duct by ONA Block offers growers the possibility to eliminate any odors in your air ducts in a natural, safe way in indoor grows.

How to install ONA Block Duct Adapter

  • It’s made out of a length of metal duct, available in different sizes, exactly the same as normal metal ducting.
  • It comes with a little hatch on one side, which should be the side that faces downwards so that you can access it easily and quickly.
  • It has a metal mesh on the inside that can fit a couple of ONA Blocks.
  • This easy system allows air to flow through and any odors to be destroyed instantly by the ONA Block.

ONA Block Duct Adapter Helps Remove Odors

Before this marvelous invention, grows used to have to undo ducting to place blocks inside and then check them periodically, but now you can get it done in a jiffy.
