Premium charcoal granules intended to refill carbon filters and efficiently scrub air in grow spaces. Actively improves air quality and promotes cleaner ventilation by blocking out odors and chemicals. Increased porosity of granular surface adsorbs greater amounts of unwanted substances than pellets. RC412 Virgin charcoal sourced from Australia features a 1200+ IAV rating for an extended lifespan. Refills 8" carbon filters 2+ times, 6" filters 4+ times, and 4" filters 8+ times for extended sustainability. Product Description Premium-grade Australian charcoal to replenish refillable carbon filters in compact and medium-sized grow spaces. The RC412 charcoal significantly improves odor and chemical suppression through its expanded internal surface area and increased porosity. Its greater adsorption rate enables larger quantities of contaminants to be trapped for enhanced ventilation. The charcoal's 1200 +IAV rating supports air quality enhancement by promoting a longer lifespan, extending the time between refills. Their charcoal pieces are smaller in size, tested to have the same odor-blocking efficacy as factory-built carbon filters without requiring active compression. Replaceable Carbon This 32 lb. supply of activated carbon can provide 2+ replenishments to 8" refillable carbon filters, 4+ refills to 6" filters, and 8+ refills to 4" filters. Together they can block odors and chemicals from escaping growing environments like grow rooms, grow tents, and hydroponic grow spaces. It can also be used in air filtration ventilation projects like laser cutting, smoking rooms, bathrooms, and more. In addition to HVAC settings, activated carbon improves aquatic environments such as aquariums, fish tanks, and ponds.
