Scrub Odors and Purify Air with Precision
Vivosun filters are designed with a specific focus on adsorption efficiency and durability. By packing high-grade charcoal into a mesh housing that maximizes surface area, these units allow air to pass through freely while chemically binding odor molecules to the carbon, ensuring that the air exhausting from your tent is completely neutral.
Stop Smells Before They Escape
The primary challenge in indoor horticulture is managing the strong aromas produced during the flowering stage. Vivosun Carbon Filters tackle this head-on with superior materials and construction.
-
RC412 Australian Charcoal: Unlike standard carbon, the Australian virgin charcoal used in these filters is highly porous, offering a massive surface area to trap terpenes, allergens, and chemical irritants.
-
High Airflow Design: The porous mesh body ensures that your
inline fan doesn't have to work overtime, maintaining static pressure while scrubbing the air.
-
Integrated Pre-Filter: Every unit comes with a machine-washable pre-filter cloth that blocks dust and debris, preventing the carbon bed from clogging prematurely.
Extended Lifespan and Versatility
Growers value equipment that lasts, and Vivosun filters are built to provide extended service life through smart engineering features.
-
Reversible Flange Technology: To ensure you get the most out of your carbon, the flanges and base can be swapped. This reverses the airflow direction, utilizing the carbon near the top of the filter that often sees less use, effectively extending the unit's lifespan.
-
Universal Fit: Designed to connect seamlessly with standard
ducting and fans, these filters fit easily into any ventilation setup, whether you are scrubbing recirculating air or exhausting heat outdoors.
-
Heavy-Duty Construction: With a galvanized steel housing, these filters are robust enough to hang securely from the ceiling bars of your grow tent without warping.
Frequently Asked Questions
How long do Vivosun carbon filters last?
Under typical growing conditions, Vivosun carbon filters generally last between 12 to 18 months. However, environments with heavy dust or extremely high humidity can saturate the carbon faster. For tips on maintaining the perfect environment to extend your gear's life, check out our guide on
how to lower humidity in your grow room.
Can I refill the charcoal in a Vivosun filter?
While some handy growers attempt to refill them, Vivosun filters are generally designed as sealed units to ensure air-tight integrity. It is often more effective to replace the entire filter or reverse the flanges to extend its life before buying a new one.
What is the reversible flange feature?
The reversible flange allows you to swap the intake flange and the bottom cap. Since the bottom of the filter usually captures more particulates due to gravity and airflow physics, flipping the flange allows you to use the less-saturated carbon at the "top," extending the filter's effective life.
Do I need a specific fan for these filters?
You need an inline duct fan that matches the diameter (e.g., 4-inch, 6-inch) of the filter. Crucially, the fan's CFM rating should be slightly lower than or equal to the filter's max CFM rating to ensure effective scrubbing. If you are setting up your ventilation for the first time, read our
complete grow room setup guide for advice on matching components.
Why is my carbon filter clogging up quickly?
Quick clogging is usually caused by high humidity (above 70% RH) or excessive dust. Ensure your pre-filter cloth is washed regularly and that you aren't running a humidifier directly into the intake.
Does this filter remove the smell of flowering plants completely?
Yes, when properly sized for your grow space and paired with the correct fan, Vivosun filters are highly effective at scrubbing 99% of organic odors, keeping your grow discreet.
