Carbon Filters

Progrow carbon has been independently Analysed in a laboratory before the filter is manufactured to ensure it has a minimum 20% butane absorption and will provide the lightest least restrictive air flow and also deliver maximum impurity filtration. Every canister is weighed after manufacture to ensure consistency with every single filter made. Expect a minimum of 2 years life and up to five years life span in low humidity environments. Don’t be fooled by cheap copies ensure you use only the highest grade 4/12 Australian Carbon.
