    Hey guys I've got 5x5 flower with a 960 cfm fan and a 8in carbon scrubber it's way over powered for my size!

    But my question is how often do you change it out? I don't smell anything but I smoke so dam much I didn't smell anything to begin with! And my house always smells like bud! I've had my current scrubber for about 18 months give or take a few!

    Never hurts to buy a second filter. Currently doing a 5x5 myself, and my 8 inch x 36 inch phresh filter cant do it on it's own so I'm also using a 6 inch filter x 24 . I just hit week 7 so I also had to turn on my ozone generator.

    To have zero smell takes extreme action sometimes. My house has no smell.

    All this is in the basement. Nothing can be smelled even in that room until you put your face on the plant. Upstairs I always have a wax smelly good burner going so when people come to the door the only thing it smells like is strawberries or apples or whatever scent i pick for the day.

    Even after 2+ years with it, no smell. Even close to 3+

    Hey mate , if its a good quality filter 2-3 yrs, depends how dusty and humid your environment is. I also have a 5x5 I use a 6inch fan and filter for exhaust and 2× 4 inch for intake... As long as you run slight negative pressure in your tent , you shouldn't smell anything at all.

    Buy an oversized filter and use saran wrap or something similar to tape off the top half of it. That way when it starts to not work as well, you can switch the wrap and pull through the top half instead. At which point that starts to lose its umph, pull through the whole thing. Phresh filters are by far the best.

    Most of my phresh filters have lasted 2 to 3 years but I have had one or two go in a year and a half give or take. Always have an extra or 2 on hand for this reason.

    I think the best brand is phresh for sure but I have had luck with mountin air I think it was and black ops was not terrible. Anything else I feel is a waste of my money. When it comes to filters dont skimp. Then again I don't feel you should skimp on any grow equipment. I have found i spend more later to upgrade the few times i have gone cheap in the past.. happy growing! bongsmilie

    I think the secret is QUALITY filter. I have 2 cheapos and they suck. They are 6 inch filters and my 4 inch canfilter was in my suit closet running some nasty smelling train wreck and my clothes never smelled. My cheapos get a whiff of weed when you walk by the exhaust.
