What does the HVC Carbon Filter 315mm x 1000mm do?
It removes strong odours and VOCs from exhaust air using activated carbon. It’s designed to keep grow rooms discreet by scrubbing smells before air exits the space. It can also help reduce general odours from pets, cooking, or chemicals, but it doesn’t filter moisture or fine particles like a HEPA filter.
What are the key specs of the HVC Carbon Filter 315mm x 1000mm?
This filter has a 315mm inlet, is 1000mm long, and weighs approximately 32.2kg. It’s rated for up to 3570 m³/h airflow, making it best suited for large grow rooms or commercial ventilation setups—not small tents.
How do I match the HVC Carbon Filter to my fan?
Choose a 315mm fan that can deliver airflow within the filter’s rating, after accounting for resistance from ducting, bends, and silencers. EC fans are ideal as you can fine-tune speed for optimal smell control and filter longevity.
Should I run the filter at full speed?
It’s best to run slightly under the maximum airflow. Slower air gives the carbon more time to adsorb odours, improving performance and extending lifespan. A speed controller helps dial in the sweet spot for your setup.
Where and how should I install the filter?
Mount it high in the room (heat and smell rise), using heavy-duty straps or anchors. Most setups have the fan pulling air through the filter. You can mount it horizontally or outside the room—just ensure all duct joins are airtight.
Can I use this filter in high humidity or hot environments?
Yes, but humidity reduces carbon efficiency. For best results, keep relative humidity below 70% and avoid placing the filter where it could get wet. High heat plus humidity can shorten lifespan, so environmental control matters.
Why do I still smell odour with the filter installed?
Check for duct leaks before the filter, overpowered fans pushing too much air, high humidity, or a filter that’s wearing out. Also ensure your space has negative pressure so all air is forced through the filter.
How long does the HVC Carbon Filter 315mm x 1000mm last?
Filter lifespan depends on odour load, humidity, and dust. In clean, well-ventilated setups, it can last a long time. If smell returns during late flower or drying, or fan speed no longer helps, it may be time to replace it.
Does the filter come with a pre-filter, and should I use it?
Most units include a Velcro pre-filter sleeve. It catches dust before it hits the carbon, helping maintain airflow and extend filter life. Always use it, and clean or replace it regularly for best results.
Can I wash or recharge the filter?
You can wash the pre-filter, but not the carbon. Once the carbon is saturated, the filter should be replaced. Industrial recharging isn’t practical for home growers, and water damages carbon efficiency permanently.
Is the filter noisy or hard to move?
The filter itself isn’t loud, but high airflow can cause whooshing or turbulence. Proper ducting and silencers help. At 32.2kg and 1m long, it’s heavy and awkward—two people are recommended for safe installation.
Can I use adapters, dampers, or silencers with this filter?
Yes, but every component adds resistance and affects airflow. Use smooth, sealed transitions and monitor performance if adding reducers, backdraft dampers, or insulated ducting. Aim for minimal bends and clean airflow paths.
Should I run this filter 24/7 or only during lights-on?
For full odour control, 24/7 operation is common. However, you can use a controller to reduce speed during lights-off. Just remember that odour doesn’t always follow light cycles, so constant extraction is safer.
How should I store the filter if not in use?
Keep it sealed in its original packaging or an airtight bag, in a cool, dry place. Carbon will slowly absorb ambient smells and moisture even when not in use, which reduces performance once installed.
