Dry air scenting technology works by an aroma bar placed in a diffuser. The scent is then diffused into the space using a noiseless fan. This tech does not emit any actual mist into your space – just scent.
Cold air scenting technology is based on aromatic oils being diffused into your space. This newer method emits an invisible mist that covers the space. Included in your rate are regular aroma bar/aromatic oil refills delivered to your door!
