AC Infinity | Activated Carbon Refill | 1200+ IAV Australian Charcoal, 8 lb.

Eight pounds of activated carbon for refilling a refillable carbon filter instead of replacing the whole unit. It is RC412 virgin charcoal from Australia, rated 1200+ IAV, in granule form. AC Infinity says the smaller granules match the odor control of factory-packed filters without needing to be compressed.

One bag refills a 6" refillable filter at least once, or a 4" filter at least twice.

Tip: pour carbon outdoors or over a drop cloth and wear a dust mask; the fine dust gets everywhere.
