①KB AIR MASK claims to be manufactured in the same factory as our company, but it has no connection to our company whatsoever.

②KB AIR MASK claims to generate 2 million negative ions, which is more than our company's Ionion MX. Our company measures this in accordance with the JIS standard set by the Japan Functional Ion Association.
When measured by the Japan Functional Ion Association, Ionion MX had a density of 690,000 particles/cm3, while KB AIR MASK had a density of 230,000 particles/cm3.

③It is said that when fully charged, the KB AIR MASK can operate for 24 hours, while the IONION MX can only operate for 20 hours.
The Ionion MX can operate for over 30 hours when new. In comparison, the KB Air Mask we purchased for our research only lasted for 17 hours.

Please be careful not to be deceived by unscrupulous sales tactics.
