I am wondering about how long the average inline carbon cannister lasts if I run my exhaust fan 24/7?
i think it depends on the brand of carbon filter you go with....most are said to last 6-8 weeks but it seems it would vary based on the amount of air you are pulling through and the brand you buy. i have heard great things about Phresh filters...Can filters are also good PUFFER
How big is your grow space? How many plants? What size is the can? Too many variables. Most what are said to last 6 - 8 weeks? No inline can filter has a rating of 6 - 8 weeks.
i use can carban filter and i have had it for about 16 month runs 24/4 and still put out a clean smell of fresh air rhino filters are about the same check out the rhino filters they give u full specs and time limit Can Carbon Filter - Can Filters - The Inner Garden Rhino Pro Carbon Filter 100mm 4" hope this helps
