• 4'' Carbon Filter & Fan Combo: Tired of fighting stubborn odors in your grow tent, basement, or bathroom? Meet your new secret weapon: our 4'' Carbon Filter & Fan Combo, built to tackle stinks, boost airflow, and keep your space fresh—no hassle, no mess.
• Crush Odors: We start with top-grade Australian virgin charcoal (IAV 1200+), the heavyweight champ of odor absorption. This stuff sniffs out and locks in smells, chemicals, and funky fumes faster than basic filters, so your grow tent, closet, or kitchen stays smelling clean.
• Built-in Powerhouse Fan:No need for extra gadgets: our combo comes with a built-in fan that cranks out 265 CFM of airflow. It’s strong enough to move heat out, pull cool air in, and circulate fresh air—keeping humidity in check and your plants (or space) happy. Plus, the included deflector focuses the airflow, so you get maximum power without chaotic turbulence. Quiet enough to not bug you, but tough enough to get the job done.
• Tough as Nails, Built to Last: We didn’t skimp on durability. The 4'' flange and base are made to take a beating—so your filter keeps working hard, longer. The heavy-duty flange fits tight with ducts (no wobbly setups here) and seals perfectly to prevent carbon leaks. No mess, no wasted filter power—just reliable performance, day in and day out.
• Smart Design = Better Results: Our double-sided galvanized steel mesh? It’s got a hexagonal pattern that opens up more space for air to flow—meaning better filtration, faster. And the removable pre-filter cloth? It nabs 99% of dust, lint, and gunk before they hit the charcoal, keeping your filter fresh for longer. Clean, simple, effective.
• Built for Where You Need It Most: Whether you’re using it as an intake or exhaust filter, this combo fits right in. Grow tents? Check. Bathrooms? Absolutely. Basements, closets, or storage rooms? It’s got your back. The 4'' flange fits standard ducts, and setup is a breeze—no fancy tools required.
