Our Affordable Clean Air Solution
We understand that commercial air purifiers are often too expensive for many schools especially in underserved areas. That’s why we’ve developed a low-cost, high-impact solution: the FiltAir Purifier, inspired by the Corsi-Rosenthal Box. What is the FiltAir Purifier? It’s a simple yet powerful DIY air purifier made using a fan, high-efficiency filters, and basic materials. It captures harmful PM2.5 particles and pollutants from classroom air. Cost Comparison: While commercial air purifiers can cost ₹20,000–₹50,000, the FiltAir Purifier is just ₹3,550—without compromising on effectiveness. Why It Works for Schools: Easy to Build: Students and teachers can assemble it together in a hands-on workshop. Effective: Removes dust, pollutants, and allergens from the air. Accessible: Extremely affordable for widespread adoption. With this purifier, we’re turning awareness into action—empowering schools to take control of their indoor air quality without depending on costly solutions.
Fresh Air for Every Classroom
Empowering Delhi Schools with Simple, Sustainable Air Quality Solutions
Our work begins when Delhi Public Schools reach out or are identified as needing air quality help. After establishing contact, we visit the school to assess its specific needs.
Through direct surveys and communication with teachers and students, we uncover the root problems, such as poor air quality, harmful particles, or gaps in infrastructure.
From there, we match each school with tailored solutions like DIY workshops, air purifiers, indoor plants, or sealing classroom walls.
Our team implements the fix, revisits for follow-ups, and continues to support schools long-term with maintenance and education. Every step is designed to make classrooms safer and healthier, sustainably.
