Review on 🌬️ VIVOSUN 6 Inch 440 CFM Inline Duct Fan with 6"x18" Carbon Filter for Odor Control - Premium Australia Virgin Charcoal Included by Anna Goetz

I really liked this filter. Supplied in an unmarked box. Almost immediately I took in all the scent from a 5 x 5 foot tent with 4 plants. strong negative pressure in my tent. Walls stretch pretty well when they're low. It's fairly quiet and not very loud when set to medium or high, depending on your needs. For example, my house has only one floor and it is in my guest room. You can barely hear it if you stand outside the room with the door closed and focus it on a low level. Turning it on I've come to the conclusion that it only really stands out when it's dead in the house. The central air conditioning is enough to drown it out. Works 24 hours a day for almost 6 months with no problems. The income from the devices has already paid off.
