Methodically capture PM0. 3 ultrafine airborne pollutants. Achieve exceptional filtration of fine particles utilising dynamic 360 filtration system technology to drastically reduce pollutants as small as 0. 3 microns¹.¹Based on external tests of Initial Fractional Efficiency and Airflow Resistance according to NIOSH TEB-APR-STP-0059(2019).99. 97% HEPA filtration Features HEPA filtration, capable of filtering up to 99. 97% of airborne pollutants as small as 0. 3 microns. Proactive protection against viruses²The filter features a special combination of materials that deactivates up to 99. 24% of trapped airborne viruses² such as Influenza A virus H1N1 and Human Coronavirus HCo V-229E.²Based on external tests for Influenza A virus A/PR8/34 H1N1 and Human Coronavirus HCo V-229E according to ISO 18184. Not tested for SARS-Co V-2. Effective anti-bacterial protection³The anti-bacterial coating eliminates up to 99. 99% of captured bacteria³ to help prevent further growth inside the filter.³Based on external tests on Escherichia coli, Staphylococcus aureus, and Serratia marcescens according to GB 21551. 2-2010 Appendix B. Intelligent purification at your fingertips Each filter is equipped with a smart tag that measures the fine particle exposure and the filter lifespan. The app indicates when it's time to replace the filter to ensure fresh air in your home.
