The BREEAM sustainability rating for buildings is highly valued today and ensures an improvement in the quality of life for occupants, a commitment to the environment, and greater productivity. Air quality is a fundamental aspect of achieving a healthy building, and although ventilation systems with filters are typically used, there are alternative technologies such as PUROH’s Open-Air Factor that neutralizes toxic compounds and pathogens in air and surfaces with the same neutral radicals produced in the troposphere. This technology is very effective, affordable, and does not require construction, making it an ideal way to increase BREEAM ratings without investing a lot of money.
