Adsorbi
Adsorbi supplies a cellulose‑based adsorbent made from Nordic forest wood fibers and recycled paper to replace activated carbon in air filtration and purification systems. The material offers higher adsorption capacity for gases such as CO, NOx, VOCs, and NH₃, irreversible capture, consistent performance across humidity levels, and a visual colour change that signals saturation, enabling longer filter life and lower environmental impact.

Problem
Air purification systems rely on activated carbon, which is fossil‑based, energy‑intensive to produce, and has a high carbon footprint. Additionally, existing adsorbents can release captured gases over time, lack clear saturation indicators, and perform poorly under varying humidity conditions.
Solution
Adsorbi provides a cellulose‑based adsorbent derived from Nordic forest wood fibers and recycled paper to replace activated carbon in air filtration and purification applications. The material offers significantly higher adsorption capacity for gaseous pollutants such as CO, NOx, VOCs, and NH₃, extending filter lifetimes by several times. Its surface chemistry binds pollutants irreversibly, preventing re‑release, and it functions consistently across all humidity levels. A natural colour change from white to darker shades signals saturation, enabling timely replacement. The adsorbent is fire‑resistant, low‑dusting, and produced with at least a 70 % reduction in CO₂ emissions compared with conventional carbon, delivering a lower‑impact solution for both active (air filters) and passive (packaging) airflow scenarios.
Target Audience
Primary customers are manufacturers of air filtration and purification systems, including HVAC, industrial gas filters, and odor‑removal equipment, as well as providers of passive airflow packaging for sensitive goods.
Features
- High adsorption capacity for CO, NOx, VOCs, and NH₃, delivering multiple‑fold longer filter life
