The BIGW Car Air Purifier integrates advanced purification technology with blockchain transparency to create real-world environmental impact. Once installed in vehicles, the purifier captures pollutants and transmits verified clean air data to the BIGW Blockchain through the BIGW App. Each registered driver—whether from a private car, fleet, or ride-hailing service—contributes to measurable air-quality improvements backed by secure blockchain records.

This verified data generates NFTs (Proof of Impact) that represent tangible positive outcomes. Once issued, these NFTs fund meaningful initiatives such as supporting underserved communities, animal shelters, and geo-tagged tree plantations. When an NFT is executed, it converts into a Verified Water Credit, linking clean air efforts with global sustainability goals and traceable social good.
