Physical sterilization

Photocatalytic technology

Using BioEm air sanitizing and purifying liquid

In CLeanTech, BioEm air disinfection and purification liquid is sprayed into the chamber and deposited evenly on human clothes for final disinfection. The components of BioEm air disinfection and purification liquid are mainly extracted from natural plants, which can effectively sterilize, disinfect, deodorize, and decompose total volatile organic compounds such as formaldehyde.

BioEm Air Sanitising and Purifying Liquid has been tested by three universities in Hong Kong (including a university technology transfer company and two well-known universities) and authorities (China National  Center for Quality Supervision and Test of Environment Protection Products and the Hong Kong Standard Testing Center) to ensure product quality and safety. It can kill various viruses, including SARS coronavirus (99.99%), H3N2 (99.99%), H1N1 (99.995%), and 100% bacteria. Meanwhile, the formula can also decompose total volatile organic compounds (TVOC) in the air, such as formaldehyde, to improve indoor air quality. The deodorizing effect is even more significant.

BioEm is a multi-functional sterilization and purification solution that can kill fungi very quickly. Effectively resist all kinds of fungi and skin allergies after mosquito bites, spray directly on the affected area, the effect is significant.
