AC Infinity Cloudline Carbon Filters

Stop merely masking odors—eliminate them. Discretion and clean air are non-negotiable for serious indoor cultivation, and the AC Infinity Cloudline Carbon Filters deliver the absolute performance you need to maintain a completely undetectable grow space. Built for seamless integration with the powerful Cloudline Inline Fans and the central Controller 69 Pro ecosystem, these filters feature an extra-thick bed of premium 1200+ IAV Australian virgin charcoal that captures and neutralizes even the most potent organic compounds. From compact 4-inch setups to commercial-scale 12-inch ventilation systems, trust this line of carbon filters to safeguard your privacy and purify your air from start to finish.

Achieve Unrivaled Odor Elimination with AC Infinity

AC Infinity engineered the carbon filter line to meet the high demands of professional growers. Their commitment to maximizing activated charcoal capacity and optimizing airflow means you achieve superior absorption without compromising the performance of your ventilation system. Protect your harvest and your privacy with filtration built for consistent, commercial-grade results.

Secure Maximum Absorption and Longevity

Your filter’s lifespan and efficacy are directly tied to the quality of its carbon media and construction. Do not sacrifice clean air for cost; invest in a system that performs longer.

Unlock maximum chemical absorption with a densely packed, 38mm bed of Australian Virgin Charcoal, known for its high Iodine Value (IAV), which guarantees maximum porosity and superior odor capture.
Maximize your equipment's operational life using durable, reversible flanges that allow you to flip the filter once the near side becomes saturated, effectively doubling the usable duration and saving you money.
Protect the charcoal media and maintain optimal airflow by utilizing a washable pre-filter cloth, which traps dust, debris, and pet hair before it can clog the carbon bed.

Sizing and Application for Every Grow Space

Matching your filter size to your fan and grow space volume is essential for efficient air exchange and effective odor control.

For smaller, stealth operations like 2x2 or 3x3 grow tents, the 4-inch kit systems provide a perfect balance of low noise, high airflow, and potent odor neutralization.
Scale up for heavy-duty 4x4 or 5x5 environments using the 8-inch filtration systems, which handle large air volumes required by powerful lighting and high-density plant counts.
Eliminate odors sustainably and reduce long-term operating costs by choosing a refillable carbon filter model, allowing you to easily replace spent media without disposing of the entire housing.

Advanced Odor Management and System Integration

True environmental control requires more than just a carbon filter—it demands comprehensive integration with climate control accessories.

For challenging, high-humidity environments, pair your filter with an XL carbon depth model for enhanced contact time and odor elimination.
Optimize the performance of your entire ventilation setup by installing a quiet duct silencer, which cuts fan and airflow noise by up to 50% without sacrificing critical CFM.

Frequently Asked Questions

How long will an AC Infinity Cloudline Carbon Filter last before needing replacement?

A filter’s lifespan is highly dependent on humidity, odor concentration, and airflow, but typically ranges from 18 to 24 months. You can often extend this life by utilizing the reversible flanges, which allows you to flip the filter when the carbon near the inlet becomes saturated.

What makes the Australian Virgin Charcoal in these filters so effective?

AC Infinity uses a premium 1200+ IAV (Iodine Adsorption Value) Australian charcoal. This high IAV means the carbon has an extremely high number of micropores, giving it superior surface area to capture and neutralize odor-causing volatile organic compounds (VOCs) compared to lower-grade carbon.

Do I need to clean my carbon filter, and how should I maintain it?

You should never attempt to wash the carbon media itself. However, you must regularly clean the washable pre-filter cloth to prevent dust and debris from restricting airflow. A clean pre-filter ensures the carbon bed remains fully effective and extends the overall life of your filter.

What is the difference between a standard filter and an XL Carbon Filter?

The XL carbon filter models feature a deeper, thicker bed of charcoal media. This offers a longer contact time between the air and the carbon, providing enhanced absorption capability and superior odor control for exceptionally pungent or larger grow operations.

Can I use an AC Infinity Carbon Filter with an inline fan from another brand?

Yes, these filters use standard duct sizes (4-inch, 6-inch, 8-inch, etc.) and are compatible with most inline fan brands, provided you match the size correctly. However, for seamless integration and optimal CFM pairing, we highly recommend pairing them with a compatible AC Infinity Cloudline fan.

Should I consider a Refillable Carbon Filter model?

Absolutely. Refillable carbon filters offer significant long-term savings and are an eco-friendly option. Instead of purchasing an entirely new filter, you simply buy bulk Australian charcoal and refresh the media in your existing, durable filter housing for sustainable odor control.

Are there other ways to reduce noise and odors in my ventilation system?

For quieter operation, ensure your fan is running at the minimum speed required to maintain your environment. Additionally, consider installing an AC Infinity Duct Silencer, which dramatically reduces the noise produced by the fan and air moving through the ducting.
