Collection: Odour Control

A carbon filter handles most odour, but gel and spray neutralisers are the backup layer — or the main line for smaller, tentless setups. ONA is the biggest name: Gel and Block for passive release, Liquid and Spray for active use, Breeze for both. OCD Cubes and Pocket Spray, plus Gorilla Gel Cherry, work the same way as cheaper alternatives. These work by evaporation, so give them some airflow.
