GPS

Naturally occurring ions are everywhere outdoors, and they are constantly working to clean the air. Ions are created with energy from rushing water, crashing waves and even sunlight. GPS NPBI technology generates ions without producing ozone or other harmful byproducts, so you can freshen the air indoors.
