Carbon Filters are an essential odour control component in any grow room. These filters allow you to neutralise the warm air as it leaves your grow room so it does not contaminate the rest of the house. Carbon Filters remove the distinct smell of fertilisers, decaying plant matter and soil that are unwelcome within the rest of your home. At 3CH we offer a range of carbon filters and pre filters in a range of sizes and prices to ensure that we have a filter that fits your budget. Choose from leading brands such as Polar Air and Rhino Carbon filters.
