Vivosun 4" Duct Air Carbon Filter

The Virgin Australian activated charcoal features a 1050+ RC 48 rating, which indicates a highly porous structure with a vast surface area. This allows it to adsorb three times more air contaminants, odor molecules, and chemical irritants than conventional carbon filters.

Absolutely. The 4-inch diameter and 14-inch length make it a perfect fit for small to medium grow tents, such as the VIVOSUN 2' x 2' Smart Grow Tent Kit, where space is limited. It provides powerful filtration without a large footprint.

The filter includes a changeable Velcro pre-filter that catches larger particles like dust and hair. This pre-filter should be cleaned or replaced every 3-6 months. The main carbon filter typically provides effective odor control for 12-18 months, depending on environmental conditions.

Yes, the Vivosun 4-inch filter is highly effective at eliminating common household odors from pets, smoking, cooking, and musty basements. Its ability to remove chemical irritants and airborne particulates makes it a versatile tool for improving overall residential air quality.

The filter connects to your 4-inch ducting. For optimal odor removal (exhaust), place it inside the tent and connect it to the intake side of your fan, like the VIVOSUN R4 Inline Fan. For filtering incoming air (intake), place it at the beginning of your ducting. For a detailed overview, check out this complete grow room setup guide.

This ensures that all air passing through the unit is forced through the activated charcoal bed, preventing any air from bypassing the filtration media. This robust design maximizes contact time between the air and carbon, guaranteeing thorough purification.

While smaller, this filter uses the same high-quality Virgin Australian charcoal as larger models. The 4-inch size is optimized for smaller spaces and lower CFM fans, delivering the same professional-grade efficiency.
