Our Visible Light Titania™ photocatalytic powder can be applied to interior wall, floor and ceiling surfaces, as well as exterior building surfaces, with binders from other manufacturers as is done now with normal titania photocatalysts with commercial binders that are designed to be unaffected by the photocatalytic activity. The resulting surfaces passively clean themselves when illuminated with sunlight or interior lighting.
Similarly, our Visible Light Titania™ photocatalytic powder can be applied to air filters for use in HVAC systems. For best effect, a full-spectrum light source must illuminate the filter.
