Grow Room Charcoal Filter Replacement

Mines at 3 years old and still no smell
 
I am going on a year and a half. I was just looking at the prefilter thinking I should wash it.
 
Reading this makes me think i change my filters too much. I buy the cheap $30ish from amazon and replace every 6 months. To be fair, i dont actually test them, i just toss them because im in prohibitionland and cant afford even a half-days stank... Id rather KNOW im good than think im good and be wrong.

Same here! lol Replace them fast because they are low $ and cheap insurance
 
After 3 years I finally changed charcoal filter. Didn’t grow everyday but got my money’s worth. It is a dyna farm 6”
 
Coming up on a year with terrabloom, if you order direct from them you can get a 16" 4inch or a 24" 6 inch. More for your money.
