Key Features
- Superior Activated Carbon: Made with 1050+ Virgin Australian activated charcoal, ensuring efficient absorption and 100% filtered airflow.
- Effective Odor Control: Specifically designed to eliminate odors and chemicals, suitable for grow tents, hydroponic rooms, and general household use (pets, smoke).
- Multiple Functions: Can be integrated with a 6-inch inline fan for both intake and exhaust air configurations.
- Durable Construction: Features aluminum flanges and dual-sided galvanized steel mesh for enhanced rust and corrosion resistance.
- Pre-Filter Included: Comes with a machine-washable pre-filter cloth to prevent carbon residue and extend the filter's lifespan.
- Reversible Flange: The design allows for reversible installation, offering flexibility in setup.
- Replaceable Carbon Pellets: The activated carbon can be replaced by removing the top cover side screws when it becomes ineffective.

Setup and Installation
- Unpack: Carefully remove the carbon filter and pre-filter from the packaging.
- Pre-Filter Application: Slide the included pre-filter cloth over the carbon filter. Ensure it covers the entire mesh surface.
- Orientation: The filter features a reversible flange and base. Determine the desired airflow direction (intake or exhaust) for your system.
- Connection to Inline Fan: Connect the carbon filter to your 6-inch inline fan using appropriate ducting and clamps (not included). Ensure a secure, airtight connection.
- Placement: Position the filter within your grow tent or ventilation system. It can be hung using straps (not included) or placed on a stable surface.
- System Integration: Integrate the filter and fan assembly into your overall ventilation setup, ensuring proper ducting for air intake and exhaust.

Operating the Carbon Filter
The MARS HYDRO 6 Inch Carbon Filter operates passively as an integral part of your ventilation system. Once properly installed with an inline fan, it continuously filters the air passing through it.
- Ensure your inline fan is operating at the desired speed to draw air through the carbon filter effectively.
- For optimal odor control, maintain continuous airflow through the filter during periods when odor management is critical.
- The filter is designed to work efficiently in both intake and exhaust configurations, providing flexibility for various grow room setups.
Maintenance
Regular maintenance is crucial for ensuring the longevity and sustained effectiveness of your carbon filter.
- Pre-Filter Cleaning: The included pre-filter cloth is machine washable. Periodically remove it and wash it to prevent dust buildup and maintain optimal airflow. Allow it to dry completely before re-applying it to the carbon filter.
- Carbon Replacement: The activated carbon inside the filter will eventually lose its effectiveness, indicated by a decrease in odor control. When this occurs, it is time to replace the carbon.
- To replace the carbon, carefully remove the top cover side screws.
- Dispose of the old carbon responsibly according to local regulations.
- Refill the filter with new activated carbon pellets.
- Reattach the top cover securely.
Note: Replace activated carbon only when the original carbon has become ineffective.

Troubleshooting
If you encounter issues with your carbon filter, consider the following troubleshooting steps:
- Persistent Odors:
- Check all ducting connections for leaks. Air bypassing the filter will not be purified.
- Ensure the inline fan is powerful enough for your space and is operating correctly.
- Verify the pre-filter is clean and not obstructing airflow.
- If the filter has been in use for an extended period, the activated carbon may be saturated and require replacement.
- Reduced Airflow:
- Inspect the pre-filter for excessive dust or debris and clean it.
- Check for any obstructions in the ducting or within the filter itself.
- Ensure the fan is running at full capacity if needed.
