Long-lasting battery life, about 45 minutes of charging, about 24 hours of use How it works: Release the negative ions into the air using a built-in carbon fiber brush system. The released anions attach to air molecules and dirty particles in the air, making them negatively charged. The negatively charged particles repel each other, fly out of your breathing space and are attracted to the near positively charged surface, forming large particles that are drawn by the center of the earth!
