IonFlow technology and products

LightAir IonFlow air purifier generates from the three corona needles billions of electrons per second that transforms into negative ions when they come in contact with the oxygen molecules in the air. The production of electrons results in a concentration of more than 250.000 negative ions per cm3 measured from one meter distance, which is, as far as we know, more than any other ionizing air purifier has ever attained before without serious side effects such as generation of unhealthy levels of ozone.

LightAir IonFlow Technology uses two pole ionizing technique. By using 110V or 220V and very low strength of current 50 mA and an effect of only 5W the technology is capable through a cascade of diodes and capacitors to accelerate an extremely high voltage of more than 200.000 eV. This enables the extremely high production of several billion electrons per second, meaning several billion negative ions per second. Consequently the particle reduction is massive as the number of ions produced at a certain time corresponds to number of particles charged and collected in a certain time.

The enormous production of ions makes it possible to effectively distribute the negative charge into all corners of a room, which means that the air in the entire room will be cleaned from particles not only the air closest to the device.

The negative ions attach to the neutral and positively charged pollution particles in the air, such as from dust, pollen allergens, smoke, car fumes, pet dander, bacteria, mold, viruses etc. It is especially effective in removing the smallest particles in the air, usually referred to as fine and ultra fine particles. These are considered the most hazardous to our health. The collector, which has a positive charge will attract the particles and slowly change color as it becomes more and more covered by particles. The collector esentially works as a large magnet for particles in the air. When necessary, the collector can easily be removed and washed clean in water and washing-up liquid. Larger clusters of particles will fall to the floor before being removed by regular vacuum cleaning.

The generation of electrons and thus the production of negative ions continuously charge particles in the air. When all the particles in the room are charged the generation of electrons decrease and the units starts to generate only as many electrons as is needed to charge the new particles that constantly enters the room. The room will stay relatively cleaner at all time as long as the air purifier is turned on.

This is the future of air purification delivered today. For your health!


We recommend that you place your IonFlow air purifier at least 3 feet (1 meter) away from all walls and furniture and that you hang the 500C model 1.5 feet (0.5 meter) down from the ceiling. If these recommendations are not followed, nearby walls and/or furniture may become somewhat dirty.

We also recommend that you place the air purifier at least 3 feet (1 meter) from all metallic objects because of their potential risk to become static and act as collectors. The small electric charge the metallic objects might attain is harmless.


LightAir IonFlow air purifier is based on traditional ionization technique, but it has been further developed and optimized, which means that the major previous disadvantage like generation of ozone has been successfully eliminated.

The basic idea to clean the air with negative ions and trap them with a collector is still the same, but the technology used to attain this objective is entirely different. LightAir has worked many years to solve the problem of ozone generation. The result is a very efficient air purifier that is completely ozone free.

LightAir recommends that you use IonFlow in rooms up to 50 m2 or 540 sq ft in a normal home environment.
It is however important to understand that depending on the sources of pollution the air purifiers capacity alters. For example, if you smoke, have a dog, work at home, frequently use printers and/or live in a busy city environment you might need two units to cover the same area. This logic goes for all air purifiers on the market.

Yes, the IonFlow products remove all types of particles. Dust, pollen, tobacco, and etc. all cause allergic and harmful reactions in many people. By removing these particles from the air, the products are able to alleviate allergic reactions.

Odors partly spring from tiny particles, which Lightair IonFlow air purifier removes very efficiently. When particles turn into gas form the air purifier has a limited ability to handle these in a larger perspective.

Two examples illustrate this very well: Smoke creates an unpleasant smell that most of us wish to avoid. Lightair efficiently remove smoke particles and thereby also the unpleasant smell. Another example is mold. Lightair handles mold spores very well and is also preventing growth of mold. In this way Lightair removes the source of smell and thereby also decrease the smell itself.

Lightair is the only air purifier scientifically proven to prevent infection of airborne transmitted virus as well as eliminate the infectivity of viruses.

The 7-year long scientific study was carried out at Karolinska Institutet and Linköping University in Sweden and published in Nature Scientific, one of the most cited scientific journals in the world.

The study included experiments on guinea pigs. The animals were exposed to influenza A (strain Panama 99). The results showed that none of the guinea pigs that were exposed to other infected animals became infected when the ionizer device was active, whereas three out of four exposed animals became infected when the ionizer was inactive.

Gases are not particles, but molecules. IonFlow, like HEPA filters, does not remove gases from the air. A true carbon filter will reduce harmful gases such as what we refer to as VOCs.

No, once the particles have attached to the collector they stay there even if the unit is turned off. It is also important to know that already at the moment a negative ion attaches itself to a particle, that particle becomes neutralized. Hence, losing its harmful effects as a virus, bacteria, allergen, etc. on humans.

No, contrary to HEPA filters which quickly loses efficiency once they get dirty (could be as quickly as a few weeks in dirty environments) the IonFlow product does not lose efficiency over time. Even if the collector get extremely dirty it still maintains its capability to attract negatively charged particles. It is important to note that it’s not the collector that neutralizes dangerous particles such as viruses, bacteria or allergens, but these particles are already neutralized in the air at the moment negative ions attached to them. Furthermore, even in the absence of a collector the ions would attach to particles causing them to eventually drop to the floor due to their increased weight or stick to walls and furniture, thereby making the air cleaner.

Yes, since the IonFlow products don’t produce any noise and are completely silent as well as extremely energy efficient we recommend to have the product on at all times. Thanks to the unique technology and its ability to evaluate the air quality, the ion generator will adjust its production of electrons accordingly. Hence, if the air is dirty more ions will be generated and vice versa.

The IonFlow products only consume 5W/h, which translates into only USD 5/year in the US, far less compared to our competitors’ products. The low consumption of energy makes the products extremely energy efficient and environmentally friendly.

IonFlow air purifier absolute noise level is at only 5dB. The relative noise level including background noise according to standard is 21dB. The threshold for hearing is usually set at 10dB. Our competitors’ air purifiers typically give off a noise between 30 and 70dB, which is potentially harmful to the human health when exposed for a longer period of time.

All our products have been tested by third-party institutes and organizations in order to ensure that we meet all current regulations and legislation around the world.


Our product’s ozone emission has been tested and approved by the Air Resources Board in California and Finnish VTT Technical Research Center of Finland. The levels of ozone that our products produce are below the detection limit of the measurement instrument (0,002ppm). Hence, the ozone generation is negligible and harmless.

Electric discharge

The electric discharge that can be felt when you touch the collector is extremely small. According to tests that Intertek performed in order to meet regulations and legislation, the electric discharge was over 2000 times below levels that would be considered dangerous. Even babies and animals can touch the collector without being harmed.

Electromagnetic field

The electromagnetic field has been tested and approved by Intertek in order to meet regulations and legislation.

Yes, our products have been used in extremely humid climates like in Thailand to drier climates like in Sweden without any decrease in efficiency or quality.

Hot and wet climate facilitates the growth of mites and mold. Buildings with poor ventilation also don’t allow humidity to disperse. The need of air purifiers are thus even greater.

As with other health-related appliances, there is a multitude of claims made by companies regarding their products’ efficiency. Air purifiers may be rated on: CADR; efficient area coverage; air changes per hour; the clean air delivery rate, which determines how well air has been purified; energy usage; and the cost of the replacement filters. Two other important factors to consider are the length that the filters are expected to last (measured in months or years) and the noise produced (measured in decibels) by the various settings that the purifier runs on. As stated above noise is often an ignored problem with air purifiers. The health consequences of a loud air purifier can be serious. All these figures and facts make it very difficult for regular consumers to properly evaluate an air purifier.

Furthermore, it is important that the tests that many companies base their statements on are properly evaluated if a fair and correct comparison between different products are to be made. Certainly if the tests are done by lesser known institutes.

HEPA filter

The majority of air purifiers today are sold with HEPA filters, because the technology has been around for some time and it’s a relatively simple solution to clean the air. However, there are many drawbacks with using HEPA filters that IonFlow are able to solve. Some of them are the following:

  1. Rapid decrease in efficiency.
  2. Noisy
  3. Expensive, frequent and inconvenient filter replacement.
  4. Focus is on cleaning the air from particles that are larger than 0.3 microns.



Many of the ionizers in the marketplace have very little or no reliable data regarding the number of ions they produce, which make it very difficult to evaluate them properly. Many ionizers that claim to produce large amounts of ions also produce ozone at levels that are above safety levels.

Other technologies that are being marketed are plasmacluster and various combinations of different technologies such as HEPA together with ionization and carbon filters.
