This is an air purifier developed to remove VOCs from the air. With built-in reformed activated carbon, this air purifier removes gaseous pollutants (VOCs, etc.), dust and microbes. Several models are available for home and business use.

This is a system for regenerating activated carbon filter that has reached its breakthrough point. The system uses superheated steam to restore broken-through activated carbon filters safely and efficiently.

A combination of ozone and ions has greatly improved the sterilization capacity above conventional levels, enabling exceptional sterilization at normal temperatures and humidity.
