ATOUR 4 Inch Activated Carbon CFF4 Air Filter with Dual Built-in Fans – Reversible Airflow for Intake or Exhaust, Odor Scrubber for Grow Tent, Hydroponics, Basement Ventilation

• Dual Built‑in Fans with Reversible Airflow – One‑Click Direction Swap – The CFF4 and CFF4D come equipped with two independent high‑performance fans – one forward‑rotating, one reverse‑rotating. With a simple switch, you can instantly change airflow direction between intake and exhaust without rewiring or remounting. One unit covers both ventilation needs.
• Complete Self‑Contained Unit with Replaceable CF4 Filter Core – This is a fully functional standalone air filter with its own dual‑fan system – no external inline fan required. The internal activated carbon filter core is replaceable with our CF4 replacement filter (sold separately), allowing you to refresh filtration performance without replacing the entire fan unit – a more economical and sustainable solution.
• Premium Australian Virgin Carbon for Maximum Odor Adsorption – Filled with high‑grade activated charcoal (iodine value 1200+), this filter aggressively captures smoke, fumes, cooking smells, pet odors, and volatile organic compounds – while the built‑in fans actively pull air through the carbon bed for thorough scrubbing.
• Optimized Airflow with Dual‑Fan Power – Two fans work together to deliver strong, consistent airflow with minimal pressure drop. The forward fan mode pushes air out (exhaust), while the reverse mode pulls air in (intake). Switch between modes on the fly to adapt to changing ventilation needs in grow tents, basements, or kitchens.
• Durable Steel Housing with Washable Pre‑Filter – Sturdy galvanized steel body withstands typical indoor and grow‑tent environments. The included removable pre‑filter traps dust and large particles, protecting the fans and carbon core for consistent performance. Complete mounting hardware included – ready to use right out of the box.
