I build my filters and re-fill. I like that I'm taking the smell OUT of the air and not adding anything to the air I'm breathing. That's just me, not saying that anything else is bad. Just what I do.
You'd prefer to use carbon that was optimal size for vapor filtration. That would be 4x6 mesh size. Slightly larger than carbon for water filtration. It's what you'd find in commercial filters. Coconut carbon is what you want. Highest Iodine number.
Can be had for $2 a pound in 55 pound orders. Shipping is $1 a pound. that's 2 cu ft.
Well, you can make a few filters from that much carbon. I use metal screen (hardware cloth) and landscape fabric. 12" dia x 20. Top and bottom are 5 gallon pail lids. So maybe $30 worth of carbon per filter? Maybe? Dunno
Where you buying it? It's like $8 a lb for aquariums...
