MELONFARM 4-Inch Air Carbon Filter with Built-In 14cm Fan – Australian Virgin Charcoal

Meet the MELONFARM 4'' Air Carbon Filter, a compact odor control solution designed for grow tents, hydroponic rooms, and other indoor spaces. It uses premium Australian virgin charcoal to trap odors and chemicals while delivering clean air flow through a built-in fan and adjustable speed control.

Key features combine robust filtration with practical design. The 38mm thick charcoal bed provides generous absorption capacity, helping to reduce stubborn smells in enclosed environments. The carbon bed is paired with a double-sided galvanized steel mesh in a hexagonal pattern, which maximizes open area for steady airflow and efficient filtration. The result is a compact unit that balances odor control with reliable airflow, suitable for tight spaces and active grow setups.

Built-in performance and quiet operation are a hallmark. The integrated fan delivers strong airflow with low noise, enabling you to ventilate the tent, transfer heat, or bring fresh air into a room without distraction. A built-in speed controller lets you tailor the airflow to your setup, helping balance odor control with noise and power consumption. This flexibility makes it easier to adapt to changing room conditions or different growth stages.

Durability and reliability are designed in. The flange and base are stiff and precise, ensuring a secure fit on standard ducting and minimizing the chance of carbon leakage over time. The removable pre-filter captures the majority of dust and particles, helping maintain the main carbon bed's effectiveness and simplifying maintenance. A thoughtfully engineered design means fewer hiccups during routine setups or frequent reconfigurations.
