Photocatalyst test data and results

Test 1 – Wind-tunnel airborne bacteria elimination

The following illustration shows the level of efficiency of QOLFAN devices in eliminating airborne bacteria. The measurements are based on analysis of “intake air” and “outtake air” readings.

Household or office environment contains undeniably less airborne bacteria compared to the malodorous premises of breeding kennels, waste storages and the like – obvious subjects to high bacteria concentration. The comparison results suggest that the QULFAN devices succeed in eliminating guaranteed 80% of airborne bacteria in these environments and effectively deodorizing the air.

Test 2 – Elimination of airborne bacteria in a general room

Test2 data-IMAGE1 Test2 data-IMAGE2

The first picture demonstrates the testing conditions with QOLFAN device installed in the middle of the room and surrounded by 5 airborne bacteria concentration measuring units.


The QOLFAN device successfully neutralized most of the harmful bacteria within half an hour period.

Test 3 – virus elimination capabilities

This test analyzed the OLFAN device’ efficiency against viruses. Adenovirus was chosen for testing purposes.

What is Adenovirus?

Adenovirus is an icosahedral structured virus that infects human upper respiratory tract and is spread via respiratory droplets. Symptoms are akin to flu or cold with particular enlargement of the lymph nodes and tonsils.

Outline of the test

Test3 data-IMAGE1

Test3 data-IMAGE2
90% of adenovirus had been inactivated on this test.

As a result, 20% of virus had been deactivated by ceramic form with coated with oxidised titanium. By using both ceramic form and ultraviolet light, we succeeded get rid of 90% of adenoviruss.

Test3 data

These pictures demonstrate the “before” and “after” of QOLFAN photocalyst device implementation against adenovirus particle concentration in air. The QOLFAN destroys the virus particle’s protective coat of protein called a capsid that plays a vital role in process of infecting human organism. With capsid destroyed, the virus particles lose their infecting capabilities, making our QOLFAN photocatalyst device exceptionally effective against adenovirus.

Testing was performed in cooperation with Institute of DNA Medicine – The Jikei University.

Test 4 – The effectiveness of photocatalyst devices against mycosis.

The test was conducted to analyze the effectiveness of our photocatalyst devices against mycosis. Mycosis is known for being one of the main reasons behind mold growth and for its’ resilience. Aspergillus was chosen for testing purposes.

What is aspergillus

Aspergillus is a common fungi found in various climates worldwide but preferring humid environments. Known as one of the causes of asthma and pneumonia.

Test 4 – 1.

The fungi were placed on the ceramic material unit and exposed to ultraviolet light for a certain period of time.

Test4-1-IMAGE1 Test4-1-IMAGE2


The combination of UV light exposure and oxidized titanium coated ceramic material unit allowed us to neutralize 50% of the fungi in half and hour, and 90% of the fungi – in 1 hour period.

Test 4-2. Photocatalyst technology effectiveness against mycosis.

The following diagram shows the testing device aimed at determining the effectiveness of photocatalyst technology against mycosis colony-forming abilities. The reading equipment were set up at the intake and outtake points of the device to capture the data.
Mycosis culture containing fluid was sprayed at the intake point of the device, taking the mycosis spores through 4 layers of ceramic material units and UV light exposure.

Test Data-IMAGE4


By going through the test device, mycosis colony-forming capabilities dropped to 5% of the initial value.


The results of Test 4-1 and 4-2 clearly demonstrate the photocatalyst technology ability to be exceptionally effective against not only viruses, but mycosis as well.

Testing was performed in cooperation with Institute of DNA Medicine – The Jikei University.
