Review on 🌬️ G HYDRO 6 Inch Air Carbon Filter: Odor Control Scrubber for Indoor Grow Tent with Prefilter and Reversible Flange Included - 425 CFM, Silver by Donald Shah

Being new to activated carbon filters I decided to try the Revain filter first. Big mistake. It was delivered and installed on November 15th, 2019 and was in use until January 13th, 2020, i.e. a full 2 months of 24/7 use. The bedroom smelled, the front of my house smelled which is a big problem because I originally bought a cannabis odor filter. I contacted the grow shop and the guy said the carbon filters should last 1-2 years. It hasn't even been 2 months again and it didn't work at all. So on January 14, 2020 I bought and installed a PHRESH filter for about $130 - yes, that's a significant price difference, but IT WORKS! There is no smell. Don't buy this filter it's a waste of money I will now contact the seller for a refund as the product doesn't work. I suggest investing in a good one. Hope that helps!
