Frequently Asked Questions



  • How does your product clean the air and what’s the principle?

  • Our product can releases massive amount of negative ions.
  • Negative ions help to clean the air by causing smoke, dust, bacteria and other harmful particles floating in the air to be attracted and stick together forming clusters.
  • These clusters of particles then become heavy enough to drop to the ground where they can be vacuumed rather than staying in suspension where they can be breathed in.
