? on carbon filters

approximately how long will a 8 inch carbon filter last 1 or 2 cycles years or what just wondering how often they need to be replaced thank you for your time guys

different factors play a part, but generally 18 months if you arent a commercial grower lol

Most are 1 year but dnt last that mine is 18 months it's a phresh filter I change it every 2 grows

Here is my question for you...how do we go about getting the filter replacements?
