Buying Guide

Match fan size to duct diameter

Choose a fan or filter listed by its inch size (3", 4", 6", 8") to ensure compatibility with your ducting and fittings

Check airflow (CFM) for grow space

Pick a fan with CFM suited to your tent or room volume; higher CFM moves more air for larger setups while lower CFM works for small enclosures

Prefer activated charcoal type

Look for filters that specify Australian or virgin charcoal for consistent odor adsorption and longer effective service life

Use speed controllers for flexibility

Variable-speed controllers let you balance noise, airflow, and plant needs without swapping hardware

Assess noise and mounting options

Inline fans with quieter operation or clip fans with 360° tilt provide flexible placement and reduce vibration transfer to the structure

Consider filter dimensions and sealing

Verify filter length and flange design to ensure a good seal in your inline setup and adequate carbon bed depth for odor control
