Allergens (mite, pollen,
mould, etc.) are
positively charged and
then captured by the
electrostatic filter.
2 Decomposition
Titanium Apatite Photocatalytic Filter
Allergens are adsorbed and broken
down by the Titanium Apatite
Photocatalytic Filter. The Flash
Streamer activates the Titanium
Apatite Photocatalyst to thoroughly
Pollen break down allergens (mite, pollen,
mould, etc.).
*2 Conditions of experiment: Allergens were irradiated for 4 hours by Flash Streamer and the breakdown of protein was verified using either the ELISA method,
cataphoresis, or an electron microscope. (Joint research with Wakayama Medical University.)
Adjuvants such as diesel exhaust particles, exhaust
gas (NOx, formaldehyde, etc.) and VOCs (volatile
organic compounds such as toluene and xylene) exist
in our atmosphere. Adjuvants not only enter rooms
through windows, but enter by clinging to our clothes.
Once inside, they attach themselves to allergens such
as pollen, mites, and mould. The Flash Streamer
thoroughly removes not only the adjuvants, but also
the heavy allergens, which consist of allergens with
adjuvants attached to them.

Formaldehyde, which continually emanates, is considered more difficult to remove than
transitory pollutants such as cigarette smoke. The Flash Streamer is able to remove it.

The falling speed of pollen is
controlled by the airflow, which
alternates between fast and slow. By
creating this gentle turbulence in the
room air, pollen is caught before it
lands on the floor where it is difficult
to retrieve.

Formaldehyde Guideline
Based on an interim report, the investigative commission for
the problem of indoor air contaminants at the Ministry of
Health, Labour and Welfare (Japan) have formulated, as
follows, a guideline for concentrations of chemical substances
contained in indoor air.

No. 1093
(0.08ppm)
From "Concentration guideline for
chemical substances in indoor air and
standard measurement method" (June,
2000), an official notice from Ministry of
Health, Labour and Welfare (Japan).
*Calculation of both units is at 25°C.
Recommended value of World Health Organisation (WHO) is also 0.08 ppm.
The change in surface structure of diesel exhaust particles were verified with an electron microscope after irradiating them with the Flash Streamer.
Following that, the change in concentration before and after air purifier operation of gaseous adjuvants were verified using the damping or constant generation method.
About the dust collection
and deodorising capacity of air purifiers:
•All harmful substances in cigarette smoke (carbon monoxide, etc.) cannot be removed.
•Not all odour components that emanate continuously (building material odours and
pet odours, etc.) can be removed.
*3 Diesel exhaust particles (DEP), benzene, toluene, ethyl benzene, xylene, styrene, naphthalene, iso-butanol, trichloroethylene, NOx, ethyl acetate, hexane, nonanoic acid, trimethyl benzene, formaldehyde,
tetrachloroethylene, dichloromethane, chloroform, and dichloroethane.
