1)Sick house syndrome and decomposition of  VOC.

It's well-known that the formaldehyde and VOC cause sick house syndrome; such as, atopic allerygy. Although new regulation of Building Standard Law has been adopted last year in Japan, no permanent countermeasure of the sick-house syndrome has made yet and additional ventilation system is being adapted alone.

“Ｗｅｌｌｃｏａｔ” reduce the VOC to the safety range and the performance will last semiparmanently.

2)Odor eliminating effect

Decompose organic matters that eliminate all kinds of odors. We have the test certificate of following odors.

1.Methylmercaptan:Initial value: 100ppmAfter 24 hours: less than 0.2ppm
2.Xylene:Initial value: 100ppmAfter 24 hours: less than 1.0ppm
3.Toluene:Initial value: 50ppmAfter 24 hours: less than 1.0ppm
4.Formaldehyde:Initial value: 25ppmAfter 90 minutes: 3.8ppm

 

3)Anti-bacterial effect

Because of the increase of hospital infection, the significance of countermeasure against the MRSA(Methicillin-Resistant Staphylococcus Aureus) becomes very popular of hospital and also in the general household. “Ｗｅｌｌｃｏａｔ” contains silver oxide that enhance the anti-bacteria effect where there is no UV. It's been used for medical institutions, food processing factories, and families who is suffering from compromised immune systems.
