BLE & STEMHub Bio-enzyme Intelligent Device

Bacterial Virus Microbial Contamination

In fact, public toilets are always the largest “households of germs". Public places have become vectors for disease transmission, mainly because the human body is full of pathogenic bacteria. When we sneeze or cough, germs spread around and wait patiently for the next person to touch them and pick them up.

Indoor Air Pollution

The public toilet space is characterised by foul odour, second-hand smoke, human body odour and other bad smells.

When IAQ reach the threshold, the Enzyme Permeable Biofilter will be triggered by the IoT cloud service through the BLE gateway.

Enzyme Permeable Biofilter

Actively capture harmful substances in the air, thoroughly eliminate VOCs, quickly remove odour, long-term sterilisation and anti-bacterial. Through full coverage and diffuse governance, use biological enzymes to absorb and degrade harmful gases generated when using public toilets, contains harmful volatile organic compounds VOCs, and odour molecules, transform it into a non-toxic and harmless end product and it has the effect of disinfection, sterilisation and anti-bacterial, and achieves a comprehensive treatment effect.

Special for Urban Public Toilets · Intelligent Control

After interacted with STEMHub IoT cloud service, this intelligent device can turn bio-enzyme to be nano-atomized. The atomized particles are small and the amount is large. The floating time of the atomized particles in the air is much longer than normal liquidic particles, which can quickly capture activated harmful substances and proceed natural degradation. Harmful The comprehensive removal rate of harmful substances is over 98%. This smart device can elliminate all kinds of bad odours, proceed air sterilisation and anti-bacterial with 24-hour intelligent control, which is also very easy to be installed.
