Our Bonded Carbon Media
Green Matrix bonded carbon filtration technology was originally developed for cleanroom and high-purity environments, and it delivers a dramatic performance improvement over standard loose-fill carbon.
Filters are manufactured from high-quality virgin coconut shell carbon with a minimum 60 CTC activity (per ASTM D-3467).1 Bonding the carbon into a solid, porous structure produces superior, consistent odor removal. With multiple bonded carbon options and the ability to custom-tailor solutions to your application, Green Ladder Technologies has a fit for your needs.
1. CTC (carbon tetrachloride) activity measures a carbon’s adsorption capacity. 60% adsorption is a high grade for HVAC and general air treatment.

Bonded Carbon vs Historical Loose Carbon Filters
Green Matrix media is engineered to optimize removal efficiency while eliminating the core problems of standard carbon filters:
- No channeling or bypass: Bonding prevents the media settling that lets contaminants and VOCs bypass loose carbon filters.
- Even filtration: Air passes evenly through the entire filter body for consistently superior contaminant removal.
- Virtually dust-free: Bonding eliminates carbon fines, so no post-filtration is needed.
Green Ladder’s proprietary bonding technology is what sets us apart. With nearly 20 years as an industry leader, we deliver effective solutions that save you time and money.
Additional Features
Green Matrix filters can be custom-manufactured to fit most existing HVAC and filtration systems, with all common media options available to target the pollutants your application needs to solve.
Every filter also includes integrated UL Class 1 anti-microbial pre-filtration, reducing biological contaminants like bacteria and extending carbon media life. All Green Matrix filters are disposable no second set of trays required.
