  • Titanium Apatite Photocatalyst

Powerfully Absorbs and Removes Bacteria and Removes Viruses!

Antibacterial 99.99%

Employs a Titanium Apatite Photocatalyst developed through nanotechnology

Titanium Apatite Photocatalyst, contains apatite, which excels at adsorbing viruses and bacteria. This apatite has been partially "replaced" with titanium at the atomic level, enabling viruses and bacteria adsorbed by the apatite to contact the titanium, which then completely removes them.

Four-layer system with photocatalyst and catechin for powerful bacteria and odour removal.

Antibacterial photocatalytic filter

1st layer: Catechin pre-filter

  • Catechin acts to removes bacteria adhering to dust. 

2nd layer: Filter roll
Rear surface of antibacterial photocatalytic filter

  • The new material, Titanium Apatite Photocatalyst, removes bacteria and removes viruses after thoroughly adsorbing them.
  • Odour molecules in trapped dust and other particles are broken down!

3rd layer: Photocatalyst 1
Antibacterial photocatalytic filter

  • Odour molecules that slip through the filter are broken down
  • The antibacterial and antiviral filter removes viruses.

4th layer: Antibacterial Photocatalyst 2
Photocatalytic filter

  • Even hard-to-decompose chemical pollutants are broken down!

Special inverter lamp

  • The photocatalyst is activated by a non-harmful ultraviolet light source.

How the photocatalyst works to remove bacteria / viruses and deodorise

Broken down to water and carbon dioxide

When light strikes titanium oxide, hydrogen peroxide (H2O2) and hydroxyl radicals (OH) are formed. These two substances possess powerful oxidizing properties and through mutual interaction they are able to decompose acetaldehydes and similar odourous substances into odourless carbon dioxide and water.



Also, a powerful oxidative removes bacteria and viruses. Because the hydrogen peroxide and hydroxyl radicals are only present at the surface of the photocatalyst, they do not pass into the atmosphere of the room.


What is catechin?

Catechin, a bitter-tasting component found in plants, is a type of polyphenol. Found in abundance in tea, it possesses antibacterial and antiviral properties. It is used in clothing such as underwear and in products such as masks and bedding.


Photocatalytic Power Breaks Down Odours & Cleans the Air

Photo deodoriser 85%

Collects and deodorises smells even from the furthest corner of a spacious living area

The photocatalytic deodorizer's large airflow and suction from four directions ensure that odours are properly collected, for performance that ranks with the best in the industry.


Be aware that the unit is unable to remove the harmful carbon monoxide that results from cigarette smoking.

Rapid deodorisation of tobacco smoke

An 85% rating refers to the Photocatalytic air purifier's ability to reduce, within 1 minute after operation, the amounts of ammonia, acetaldehyde, and acetic acid by 85% delivered by the smoke from five burned cigarettes in an enclosed 1-m3 space.


Large air flow and four-directional suctiom

Large air flow 420m3/h

Large Airflow + 4-directional Suction

Large airflow means speedy particle collection and rapid odour breakdown. In addition to home use, this powerful performance is great for offices, shops, medical waiting rooms, and other places of business.


Four-directional suction

Even when installed on the floor, the newly-designed, four-directional air suction at the top of the unit exhibits superlative power. Dust and odors are relentlessly sucked in from all corners of the room: above, left, right, and front. 


Quiet Operation

Ultra quiet 16dB

Quiet enough for any room!

Along with its powerful dust collecting and deodorizing performance, this unit is very quiet, allowing you to use it with confidence in places where silence is valued, such as office meeting rooms and home bedrooms.


Newly Developed fan

The secret is in the fan

Developed to minimize the turbulence and eddy currents caused by airflow, Daikin's new fan and non-clogging photocatalytic filter ensure in quiet operation, not only in the LL mode but even during the powerful flow of air delivered in the H mode.
