VIVOSUN 6 Inch Inline Fan With Filter Kit
The VIVOSUN 6 Inch Inline Fan Kit combines a galvanized steel inline fan rated at 390 CFM with a carbon filter and 8 feet of ducting. The system is designed to remove heat and humidity from grow tents while pulling odors through an activated carbon bed. The fan operates up to 2450 RPM with a maximum noise level of 34 dB, offering strong airflow without excessive noise. The carbon filter uses interior/exterior mesh and 1200+ RC 412 virgin Australian activated charcoal to capture contaminants, helping maintain a cleaner grow space.
VIVOSUN Smart Air Filtration PRO G6 Kit
This kit features the AeroZesh G6 6” inline duct fan paired with a GrowHub E42A WiFi controller, a 6” carbon filter, and 8 feet of ducting. The GrowHub E42A allows precise control of fan speed and airflow, with automatic environmental monitoring for temperature and humidity via an app. The mixed-flow design distributes air over longer distances, while a PWM-controlled motor keeps power consumption modest and noise low (32 dBA). A built-in probe monitors internal and external conditions, helping maintain optimal VPD for your plants.
Hon&Guan 4″ Filtration Kit
This 4″ kit provides a balanced solution for smaller grow tents. It includes a 4″ inline duct fan with a speed controller, a 10″ high carbon filter, and 8 feet of ducting. At 130 CFM, it delivers effective airflow with a notably quiet operation (26 dB). The odor-absorbing RC 48 activated carbon with a substantial 38mm bed delivers strong odor control, making it well-suited for apartments or rooms with close neighbors.
AC Infinity Refillable Carbon Filter Kit 4”
This kit emphasizes sustainability with a reusable carbon filter and a refill option. The included refill matches the filtration capacity of two standard 4” carbon filters, enabling long-term cost efficiency. Removable twist-off flanges simplify refilling using the included funnel and scoop, reducing maintenance downtime. This design is ideal for growers seeking lower ongoing replacement costs without sacrificing filtration performance.
AC Infinity 6″ Carbon Filter Kit
This 6” carbon filter utilizes premium Australian virgin charcoal for robust odor control in larger grow spaces. The gunmetal powder-coated exterior provides durability in high-humidity environments. Its design supports inline duct fans commonly used with 6” systems, offering strong adsorption capacity and a longer filter life. It is compatible with a variety of 6” fans and ducting configurations for flexible installations.
AC Infinity Air Filtration Kit 4” CLOUDLINE LITE
This kit pairs a CLOUDLINE inline fan with a carbon filter for 4” installations, delivering silent and efficient airflow. The prefilter cloth on the carbon filter adds an extra layer of odor control, using 1200+ IAV activated charcoal to block odors before they escape the tent. The combination is suitable for compact grow tents and hydroponics setups that require quiet operation.
VIVOSUN Smart Air Filtration G4 Kit 4”
The G4 kit includes a 4” AeroZesh inline fan, an E12 speed controller, a 4” carbon filter, and 8’ of ducting. It provides precise speed control with PWM, a quiet operation at 28 dB, and a compact footprint ideal for smaller grow rooms. The E12 controller supports app integration where available, and the kit is designed to stabilize temperature and humidity while efficiently circulating air.
AC Infinity Refillable Carbon Filter Kit 6”
This 6” refillable carbon filter kit mirrors the 4” model with a patented reusable design, allowing users to refill carbon without replacing the entire unit. It includes one refill to match the capacity of two standard 6” carbon filters, offering a cost-efficient solution for high-odor control in larger grow rooms. Removable flanges support easy, tool-free refilling using the included funnel and scoop.
Buying Guide: Key Considerations For Selecting A Carbon Filter Kit
- Grow space size and ducting compatibility: Match filter size (4″ vs 6″) to your tent or room dimensions and the inline fan you plan to use.
- Filtration capacity: Look for activated charcoal volume and media quality. Higher charcoal load generally improves odor removal and longer filter life.
- Airflow vs. noise: PWM-controlled fans reduce energy use and noise. Consider measured dB ratings to choose a quiet unit for living spaces.
- Maintenance options: Refillable or refillable filters lower long-term costs, but ensure availability of replacement media and ease of maintenance.
- Monitoring features: Built-in temperature and humidity sensors or app-controlled systems help optimize ventilation strategies and plant health.
- System integration: Some kits include smart controllers or app connectivity; ensure compatibility with existing grow tent hardware and environment.
- Durability and materials: Look for rust-resistant housings and robust filters, especially in humid grow rooms.
- Noise management: If you need stealth operation, prioritize low-noise models (under 30 dB where possible) and consider fan placement to minimize sound transmission.
When assessing options, compare total airflow (CFM) to your tent’s heat load and plant canopy size. For larger spaces or higher intensity lighting, a 6″ system with a high-CFM fan and a quality carbon filter offers stronger odor control and better air exchange. For small grow tents, a 4″ kit with efficient filtration and quiet operation can be sufficient. Evaluate whether you prefer a basic kit or a smart, app-controlled system for more precise environmental management.
