Green Nanotech Air Filter Cleans Indoor Air & Grain

An Indian research team has achieved a breakthrough with a newly patented, indigenous green nanotechnology-based air filtration system. This innovative technology is designed to combat indoor air pollution in various public settings, including schools and hospitals, and to prevent microbial spoilage in grain warehouses.

The specialized filters are coated with eco-friendly nanoparticles synthesized using plant extracts. These include silver (AgNPs), zinc oxide (ZnO), and copper oxide (CuO), which not only capture dust and microorganisms but also actively destroy them.

Field trials have shown remarkable efficacy, with airborne bacterial load reduced by 72.7% and fungal contamination by 66.9% in classrooms. Grain storage facilities also saw substantial improvements, experiencing a 68.3% reduction in bacterial and 68% in fungal loads.

This development offers a safe, cost-effective, and environmentally friendly solution to pressing air quality and food security concerns. The nanotechnology employed effectively targets harmful microbes like Aspergillus and Staphylococcus, which are linked to respiratory ailments and spoilage.
