T-2 doesn't cover up smells, like conventional air fresheners, it actually attacks the root of the smell by causing the breakdown of the origin of the odor (ammonia, aldehyde gas [smoke], etc).

Titanium dioxide is non-toxic and therefore is used in cosmetic products (sunscreens, lipsticks, body powder, soap, pearl essence pigments, tooth pastes) and also in special pharmaceutics. Titanium dioxide is even used in food stuffs, for instance in the wrapping of salami. Small amounts added to cigar tobacco are the cause of the white ash cigar smokers so cherish.

When light strikes T-2, the powerful Hydroxyl radical is released. This radical combines with offensive odors and undesirable air particles to remove them safely and effectively.
