From a fellow grower: What is the best air purifier that removes the noticeable aroma of growing? I only grow for personal use (4 plant tent).
Something with a carbon filter
Phresh Filter 6 in x 24 in 550 CFM https://www.amazon.com/dp/B0032JULLY/ref=cm_sw_r_cp_api_i_K1ZMDbVF9GKVP
AC Infinity CLOUDLINE T6, Quiet 6" Inline Duct Fan with Temperature Humidity Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics https://www.amazon.com/dp/B074XBXFPD/ref=cm_sw_r_cp_api_i_B2ZMDbC5XW85M
I second phresh filters, they work great!
