Nano enhanced air purifiers operate by employing a variety of mechanisms:
1. Filtration: Nanofibers create a dense and highly efficient filter that can trap particles as small as 0.1 micrometers, such as viruses and ultrafine pollutants. 2. Catalysis: Nanoparticles like titanium dioxide (TiO₂) can act as catalysts under UV light to decompose harmful organic compounds and bacteria through photocatalytic reactions. 3. Adsorption: Materials like activated carbon are enhanced with nanomaterials to increase their adsorption capacity for volatile organic compounds (VOCs) and other gaseous pollutants.
