Improved efficiency of air conditioning

In winter, warm air from the air conditioning will quickly spread through the room and become warm.
In summer, cool air from the air conditioning will quickly spread through the room and become cool.

Tested at Chiba University Fungal Medical Research Institute

Methodology

Bacterial Strain: Aspergillus niger IFM 54309
0.1ml of 1×106 Spore suspension/ml is placed on a sample and left for 7 days at 25°C (wet tissue was left to keep the humidity constant).

1.Placing potato dextrose agar (PDA) on a culture media directly and cultivate for 7 days at 25°C

2.Stirring with 5ml of surface-active agent and applying 0.1ml of it to PDA culture, cultivate for 7 days at 25°C.

Result
There was no mold observed for Healthy Wallpaper “Ken”, and therefore, the difference between the controlled culture and “Ken” is observed.

Odor test is conducted already

The surface of “Caby-sheet” is coated by ceramic, and therefore, it does not cause static electricity and prevents the room from having an odor due to dust. “Caby-sheet” can make your room into a refreshing place.

Healthy wallpaper, “Caby-sheet”, odor measurement test

The result of “Caby-sheet” and a standard wallpaper’s odor measurement test (simplified method)

1.The purpose of measurement:
Verifying the deodorizing effect of “Caby-sheet”

2.The date of measurement:
Standard wallpaper was measured on March 14th, 2018 from 13:30 to 15:00.
“Caby-sheet” was measured on April 5th, 2018 from 13:30 to 15:00.

3.The measuring instrument:
Handy Smell Monitor OMX-SR (Shinyei Technology Co., LTD.)

4.Measurement methodology:
From 13:30 to 13:45, burning 5 pyrethrums (mosquito repellent) in a library,
and then take them out of the library. From 13:45 to 15:00, measure the smell of the pyrethrums at the library.

5.About the simplified method:
Odor measurement is done by multiple instruments. Therefore, it is costly to measure an accurate level of smell. Therefore, to simplify the methodology, this test used an available instrument and used pyrethrums as odor. Please refer to this data as a simplified reference.
