Air surrounds us, we can not live without air

We can choose which food to eat.

This is somewhat different with air! We have no choice at all. We must breathe it - it provides us with oxygen.

Equally trivial and fundamental

The quality of the air we breathe plays a vital role in our wellbeing and health. 

Air is polluted by natural and man-made substances.

Natural pollution:

  • Bacteria and viruses
  • Mould spores
  • Pollen and allergens 

Mostly man-made pollutants:

  • Fine dust and fumes
  • Cigarette smoke
  • Formaldehyde

 Tiny particles underly all these pollutants - particles with a diameter of less than 0.1 micrometers.

For comparison: 

  • The human eye can perceive particles from a size of approximately 30 micrometers.
  • A human hair has a diameter of approximately 50 micrometers (0.05mm)

 The human body is very capable of filtering particles with a size of one micrometer or more itself.

On the other hand, we can not filter smaller particles ourselves. They can enter our respiratory system unchecked.

Many of these particles are hazardous to our health and may accumulate in the lungs.

Cigarette smoke, soot or smoke from the hob, fireplace or fumes from traffic or pollen, viruses and bacteria need to be mentioned in this context.

According to research conducted by the Technical Research Institute of Sweden, approximately 90% of questionable particles in the air are smaller than one micrometer, making them too small for the body to filter them effectively.

Modern ion-technology makes it possible to remove these tiny particles from the room air.

The Karolinska Institutet in Stockholm, Sweden has proven under clinical conditions that influenza viruses can largely be removed from the air using ion-technology.

Effizient against influenza viruses (true influenza)

ENVIRONMENT: Air purification - nature report: IonFlow technology is proven to reduce a large part of influenza viruses

The unique LIGHTAIR IonFlow technology protects you from infection with influenza viruses in the air.

The Nature Scientific Reports - the professional periodical Nature’s primary scientific trade magazine published a study on the efficiency of the IonFlow technology on the 23rd of June 2015.

The department for microbiology at the renowned Karolinska Institutet in Stockholm, Sweden, supported by the Swedish Research Council (LS) 32031, studied the influence of ionised air on differently types of influenza viruses.

The device used for the scientific laboratory testing is based on the IonFlow technology by LIGHTAIR AB from Solna in Sweden.

Ionizing air affects influenza virus infectivity and prevents airborne-transmission

Summary of the report:

A LIGHTAIR ionising device was modified for the laboratory tests.

An effective prevention of influenza A viruses (strain Panama 99), which are transmitted by air was proven.

The influenza infection’s transfer between two groups of guinea pigs was observed.

An active ionizer was 100% efficient at protecting the first group, while the second group - without inoized air - became diseased.

Furthermore, it was discovered that the device efficiently attracted airborne viruses and deactivates up to 97%. Calici viruses, rota-viruses and influenza-viruses were examined.

The ionizer generates negative ions and passes these on to the air.

These negative ions then charge fine dust, nano-particles, aerosols, viruses, etc. by surrendering their own charge.

The charged particles are attracted by the positively charged collector surface.

The collected viruses were then recorded quantitatively in real time.


The device (LIGHTAIR IonFlow) offers unique possibilities to rapidly remove viruses from the air.

ENVIRONMENT: Air filter - lab experiment - LIGHTAIR IonFlow absorbs smoke

Smokebox test

For this test, a LIGHTAIR IonFlow was placed inside an airtight box (plexiglass tube).

The tube was then filled with dense smoke (incense).

It was quickly observed that the LIGHTAIR was able to absorbe the heavy smoke within a short period of time.

The graphic above gives an overview of different pollutants and their sizes.

Depending on their size, some of these are visible to the naked eye (e.g. household dust), but microscopes or even scanning electron microscopes become necessary when dealing with smaller particles.

Important information:

By far the major portion of these particles - approx. 90% - is invisible to the naked eye!

Scientific research has proven the efficiency of the LIGHTAIR IonFlow’s ion-technology.
