The V-Air® SOLID particles enable superior fragrance delivery, yet are sized typically below 1.0 micron. This means they are much smaller and lighter than the particles in other fragrance systems, remaining airborne for many hours. The technology behind V-Air® SOLID is packed into one powerful refill component, so the hard work is done for you – no fuss,just fragrance. A fully recyclable retaining clip attaches the refill to the dispenser.
