34 Function and Control
1.11.4 Air-Purifying Filter with Photocatalytic Deodorizing Function
This filter combines the Air Purifying Filter and Titanium Apatite Photocatalytic Deodorizing Filter in
a single highly effective unit. The filter traps microscopic particles, decomposes odors and even
deactivates bacteria and viruses. It lasts for 3 years without replacement if washed once every 6
months.
1.11.5 Air Filter (Prefilter)
The air filter material is permeated with a safe, odorless mold preventative to make the filter
virtually immune to mold.
1.11.6 Auto-restart Function
If a power failure occurs even for a moment during operation, the system automatically restarts in
the previously existing mode as soon as power is restored.
(Note) It takes 3 minutes to restart the operation because the 3-minute standby function is
activated.
