Featured Case Study

Rusutsu Resort Hotel & Convention

Hotel & Resort Facility

Challenge

• Using ozone deodorizers after strong odors or norovirus incidents
• Staff had to leave the room during disinfection, causing housekeeping delays

Solution

• Introduced SterilizAir on continuous operation
• Staff can handle odors quickly while remaining in the same space

Added Value

• Odor reduction while guests are in the room
• Guest complaints eliminated — used as 'room upgrade' benefit
• Zero virus infections achieved through continuous operation

"Operations improved dramatically as a replacement for ozone generators. The biggest deciding factor was reducing the number of rooms taken off sale."
