Boysen® KNOxOUT™ air cleaning paint is a water-based coating that uses a revolutionary new technology to break down noxious air polluting gases into harmless substances through an environmentally safe process called photocatalysis. It is also self-cleaning and has antibacterial properties

KNOxOUT™ is the first air cleaning paint in the world with CristalActiv photocatalytic technology. It uses light energy to break down noxious air pollutants and convert them into harmless substances. Any surface coated with KNOxOUT™ instantaneously becomes an active air-purifying surface that helps protect people from harmful gases. Photocatalysis also provides KNOxOUT™ with self-cleaning, anti-bacterial and de-odorizing properties.
