Vivosun 8" Duct Air Carbon Filter

The Virgin Australian activated charcoal features an exceptional 1050+ RC 48 rating and an optimal pore structure. This creates a massive surface area that traps and neutralizes odor molecules and chemical irritants far more effectively than lower-grade carbon, resulting in cleaner air.

Absolutely. The 8-inch diameter and 22-inch length are specifically designed for the high-volume airflow of large grow rooms and commercial facilities. It effectively handles the intense odor output from many plants, making it a reliable choice for professional growers.

The filter includes a changeable Velcro pre-filter that catches dust and larger particles. This pre-filter should be washed every 30-60 days. You can purchase a replacement 8" pre-filter cloth to avoid downtime. The carbon filter itself typically provides effective odor control for 18-24 months, depending on usage and environmental conditions.

Installation is straightforward. Connect the filter to your 8-inch ducting and inline fan using duct clamps. It can be placed at the beginning of your ventilation system (as an intake filter) or at the end (as an exhaust filter). It's a key part of complete systems like the Vivosun AeroZesh G8 Smart Air Filtration Kit.

This filter performs best in environments with relative humidity below 75%. High humidity can saturate the carbon pores with water vapor, reducing its odor-absorbing efficiency. For tips on managing your environment, check out our guide on grow room temperature and humidity.

While using the same high-quality Australian charcoal, the 8-inch filter contains significantly more carbon and has a larger surface area than 4-inch or 6-inch models. This allows it to handle much higher airflow volumes and neutralize more intense odors, making it the superior choice for larger spaces.
