A Smarter Carbon Filter
Traditional carbon filters are designed to be discarded once the activated charcoal reaches the end of its working life. The AC Infinity Refillable Carbon Filter offers a more sustainable solution by allowing you to simply empty the used charcoal and refill the filter with fresh activated carbon.
This innovative design helps reduce waste while significantly lowering the long-term cost of maintaining your ventilation system. Rather than replacing the complete filter housing, you only replace the activated carbon when required.
Premium Australian Activated Charcoal
Each filter is filled with premium Australian RC412 virgin activated charcoal featuring a 1200+ IAV rating. This highly porous carbon provides exceptional adsorption of unwanted odours and airborne contaminants while maintaining excellent airflow through your ventilation system.
Every kit also includes an additional charcoal refill, giving you enough activated carbon for approximately two complete filter fills before purchasing more replacement carbon.
Simple Tool-Free Refilling
The removable aluminium end caps twist off easily, allowing quick access to the carbon chamber without specialist tools. The included refill funnel and scoop make replacing the activated charcoal fast, clean and straightforward.
The filter has been designed so the carbon naturally settles into the correct position without requiring excessive compression, helping maintain optimum airflow and filtration performance.
Built for Long-Term Performance
Constructed from heavy-duty galvanised steel mesh with corrosion-resistant aluminium flanges, the refillable filter is built to withstand demanding indoor growing environments. The reversible flange design also allows the filter to be rotated during use, encouraging more even carbon usage and extending its overall service life.
