Leitz TruSens captures 99,99% of airborne human coronavirus which is a surrogate for SARS-COV-2, the virus that causes COVID-19*

Results from independent third party testing using aerosolized airborne concentration of human coronavirus 229E. TruSens air purifiers captured 99.99% in a two-hour period in a 30m3 test chamber. There is no generally accepted test method to determine the viral load of air. The test was conducted by The CAS Testing Technical Services (GuangZhou) Co., Ltd. (No. 368 Xingke Road, Tianhe District, Guangzhou, P. R. China) using a Chinese standard (Technical Standards for Disinfection (2002) 2.1.3).

Captures and destroys pollutants*

360 degree filtration captures common pollutants such as allergens, VOCs, certain gases and ultra-fine airborne particles including viruses and bacteria. A UV-C lamp also destroys bacteria, germs and viruses that are captured within the filtration system for added peace of mind.

The filter is at the core of purifying your air

4 Levels of Purification

The TruSens combination filter has been engineered to capture ultra-fine airborne particles, allergens and volatile organic components (VOC’s), and odourous gases.


Washable Pre-Filter* – captures large particles such as dust and pet hair

Activated carbon – removes certain gases and odours from the air

HEPA filter – captures particulate matter down to 0.003 microns

UV sterilisation – reduces the growth of odour-causing microbes on the surface of the filter.
