ATOUR 4-Inch Carbon Filter + Built-In 265 CFM Fan — Australian Virgin Charcoal

Powerful Odor Control in a Compact 4-Inch Package

Take control of the air you breathe with a compact, high-performance filter and fan combo. This 4-inch unit pairs an advanced carbon filtration core with a built-in 5.5-inch quiet fan and adjustable speed, delivering steady airflow without a bulky setup. The system is designed to fit standard ducts, making installation straightforward in grow tents, bathrooms, basements, or storage rooms. With Australian virgin charcoal at its core, this filter targets odors and keeps airflow balanced so you can focus on your tasks or projects.

Australian virgin charcoal (IAV 1200+ grade) offers high porosity and fast odor absorption, helping keep spaces smelling fresh. The carbon bed works in concert with a double-sided galvanized steel mesh that opens up space for air to flow, improving filtration efficiency. A removable pre-filter captures dust, lint, and small debris before they reach the charcoal, helping prolong the life of the core.

Built-in fan and airflow design The included 5.5-inch style fan delivers up to 265 CFM of airflow, moving heat out and pulling cool air in to help balance humidity. A deflector focuses the airflow for maximum power with minimal turbulence, while the compact form fits tight spots. This unit is quiet enough for regular use, yet tough enough to handle constant operation in a grow space or bathroom.

Durability you can count on The 4'' flange and base are built to endure frequent setup and teardown. The heavy-duty flange creates a tight seal with standard ducts, helping prevent leaks and waste. The overall construction prioritizes long-lasting performance, day after day.
