Air Pollution Air Purifier UK — PM2.5 & NO2 Protection

Last updated: January 2026 | Reading time: 5 min | Verified by experts

Urban air pollution — PM2.5 fine particles, nitrogen dioxide (NO2), ozone (O3), and black carbon — penetrates indoors and poses serious health risks. The European Environment Agency links PM2.5 exposure to 400,000 premature deaths annually in Europe. Our Corsi-Rosenthal DIY Kit with HEPA H13 filtration removes 99.95% of PM2.5 and ultra-fine particles, while activated carbon layers absorb NO2 and gaseous pollutants, creating a clean-air sanctuary in polluted urban environments.

At Clean Air Kits, we've developed premium DIY air purifier kits based on the proven Corsi-Rosenthal Box design. Our kits are Energy Star 2026 certified and independently tested to be 2.4x more efficient than commercial alternatives like Dyson.
