I used these old can filters for years. 1 small 4 incher diy with ground charcoal. The one I just changed had pellets and I ran it for years no trouble. Now In 2 bd apt with Mrs that can’t handle the smell anymore.
I believe it’s psychosomaticst lol
I changed it out cuz I can’t take the chance of pissing her off. Going th refill with the granitor charcoal I have on hand. But yeah, I’ve got this 5 footer 150lb can I use for a air scrubber for lung room. Going to fill it with the cheaper pellets and I’ll keep it updated on smell removal and length of time.
Can’t wait to cracked that 5 footer. If she’s filled with pellets. I’m sold cuz I’ve had an run this can the most over the years and it’s still cleaning the smell.
Happy growing bro
