Founded in 1999, FLORY is dedicated to creating a comfortable and healthy indoor environment through technology. FLORY has been engaged in the air purification area since 2012.

In 2014, FLORY established a laboratory with Shanghai Jiao Tong University and invented catalytic filters that can decompose ozone into oxygen. This ozone-decomposing filter can work at normal temperature and last for ten years.

FLORY combined ozone-decomposing filters with ESP (Electrostatic Precipitator) technology into the ESPCC technology, which can efficiently eliminate particles (PM2.5 & PM10) and inactivate viruses and bacteria without worrying about the by-product of ozone. It not only eliminates ozone generated by the Electrostatic Precipitator but also ozone from outside.

These ozone filters have been in use for nearly ten years since 2014. The ozone filters have been installed in the CITIC Tower (the tallest office building in Beijing) since 2018. The ESPCC combination filters have been installed in The Oriental Pearl Tower (the landmark of Shanghai) since 2020. All the filters are working in good condition. The ozone filters and ESPCC combination filters have been used in more than 200 buildings in China.

FLORY continues to research and develop new ozone filters. The second generation of ozone filters is more economical, has lower resistance, is more flexible in shape, and offers more size options. It can be used in more situations and areas.
