Titanium apatite is a new photocatalytic 
material with advanced adsorption power. While
the filter’s micron-level fibres trap dust, this photocatalyst
effectively adsorbs and decomposes bacteria.
The photocatalyst is activated simply by exposure to
light. The filter delivers consistent performance for
approximately 3 years if periodic maintenance is
performed. This filter is not available with FTKS50B.

When cooling or dry operation is stopped, fan-only
operation runs automatically for 1 hour. This airflow
dries the inside of the indoor unit to reduce the
generation of mould and odours. It is available with
FTKS25/35D.
Mould-Proof Operation

Flat panel models can be cleaned instantly
with a single wipe of a cloth across their
smooth surface. If more thorough cleaning is
required, the panel can also be easily
removed from the unit.
Wipe-Clean Flat Panel
Front grille design units
collect dust on their air
inlet grilles unless these
grilles are cleaned
regularly.
1. Difficult to remove dust on the
grille through wiping alone
2. Reduced capacity due to
increased suction resistance
3. High sound levels due to
increased suction resistance

Dust
Apatite adsorbs bacteria. At the
same time, the photocatalyst
oxidises odour components,
breaking them down.

The Air-Purifying Filter with Photocatalytic Deodorising
Function is made of titanium oxide. It adsorbs and
decomposes bacteria. The photocatalyst is activated
simply by exposure to fluorescent light. This filter is
installed in FTKS50B only.
