Zero-waste carbon filters to eliminate odours from your indoor grow tent or hydroponic grow room. 

Through our patented replaceable design, the outer housing of the carbon filter never gets replaced once attached to the inline fan. To change the filter, slide the old carbon cartridge out and slide the new one back in.

Features a stainless steel outer housing and galvanized steel carbon cartridge for superior quality. Contains above-standard North American 4-mm granular carbon in a 2"-thick carbon bed.

The trusted choice by Canadian licensed producers and perfect home growers. 

Includes: 1x outer housing, 1x carbon cartridge, 1x pre-filter
