February 27, 2013, Hyderabad, India – Kitasato University, School of Allied Health Sciences, Microbiology Research Laboratory, conducted tests of Comfor’s Water’s (or Ecolle Water’s ) inactivation effect of human influenza virus. Test Method and result are as follows:-

 

•     Test Method – In a cabinet, size of 1m x 1m x 1m, human influenza viruses were exposed by spraying comfort water (Ecolle water) with 50 ppm of concentration. The water number of virus –infected particles was counted with respect to each pre-deter minded lapsed time from the start of spray.

•       Result – 1 minute after the start of spray, the number of virus-infected particles decreased 66%. Then, the decreased along with each determined –lapsed time, and 20 minutes later no detection was recognized.

Table:

0	9.3 x 106 puff/ml	-------
10	3.1 x 106 puff/ml	33.3% (66.7%)
30	2.1 x 106 puff/ml	22.5% (77.5%)
50	1.8 x 106 puff/ml	20.0% (80.0%)
100	2.5 x 105 puff/ml	2.6% (97.4%)
200	< 10 puff/ml	-------

•     Prospect – It is considered that spray of Comfor Water ( Ecolle Water) has an inactivation effect of human influenza viruses in a significantly short period of time and with a small amount of it.
