The Fresh Air Buddy creates an almost particle-free "exclusion zone" around the wearer by generating high intensity ion streams that add charges to nearby airborne particles. These charged particles repel each other and adhere to surfaces out of your breathing zone. This means substantially decreased concentrations of toxic allergens, smoke, dust, viruses, and bacteria in the air you breathe and the air that contacts your eyes. With most viruses and bacteria measuring between 0.04 and 3 microns in size, the technology in the Fresh Air Buddy has been confirmed by world authorities in health-related aerosol studies to significantly reduce particles of this size range. This significantly decreases the probability that these particles will be inhaled, giving you cleaner, fresher air to breath, and a reduced risk of adverse health effects.

Using the same technology as the Fresh Air Buddy, Ecoquest makes a small space ozone purifier called the Focus.
