We stock a variety of carbon filters which prevent bad odor escaping from indoor grow tents and grow areas. Expect your carbon charcoal filter to last up to 2 years in areas of high humidity, e.g. Brisbane, and even longer in drier areas down the southern parts of Australia. We also have electronic air purifiers which remove odors, vapours, bacteria and viruses from the air. Grow tent filters are a must for controlling herb and flower smells.
