1. The indoor air is full of particles that come from yourself, your surroundings and your daily activities such as bacteria, virus, mold, pollen, car exhaust, dust, etc


2. Lightair IonFlow 50 generates billions of electrons per second that transforms into negative ions.


3. The negative ions charge the particles in the air negatively

4. Once the particles have been negatively charged they are attracted by the positively charged collector which essentially acts like a large magnet for dirt. IonFlow 50 is especially effective in removing the smallest particles in the air, which are considered the most hazardous to our health.


5. The collector will become dirty on the outside. How dirty and how fast depends on how polluted the environment is where it is placed.


6. When necessary, the collector can be easily removed, rinsed in water and then reused.

How does it work detail

Lightair IonFlow 50 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.


The 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 7W 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 positively charged pollution particles in the air, such as from dust, pollen allergens, smoke, car fumes, pat dander, bacteria, mould, viruses etc. It is especially effective in removing the smallest particles in the air, usually referred to as fine particles. These are considered the most hazardous to our health. The collector will be covered by particles and slowly change color as it becomes more and more dirty. 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 positive charge that can be felt when touching the collector is far below the safety threshold value and is necessary to attain the strong attraction of particles. It is completely harmless!


The generation of electrons and thus the production of negative ions continuously charge particles in the air. This process takes some time depending on the size of the room. 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.

It is especially effective in eliminating the smallest particles that are considered to be most dangerous to our health. The efficiency is proven by several third party test institutes. Please learn more under Performance.

No expensive filter to replace instead a reusable collector that you easily wash clean in water and washing-up liquid when needed. The fact that you never need to buy a filter will save you lots of many in comparision to filter-based air purifiers.

Less than 5 dB. For reference; a level of 45 dB indoors is identified as preventing activity, causing interference and annoyance. Most other air purifiers have a noise level of 35-80 dB.

Uses less than 7W per hour, which is much less than most other air purifiers. The energy consumption is highly relevant as all air purifiers should be turned on at all times to efficiently keep the particle concentration down.

The ozone level is not even measurable and thus considered to be equal to zero. This is the first time, as far as we know, that anyone has managed to obtain a high emission of negative ions without producing ozone as a bi-product!

An object of desire! Lightair IonFlow 50 has earned several prestigious design awards, among others the International Design Excellence Awards (IDEA). It offers you a stylish alternative to typical industrial looking air purifiers.

Just plug in and let it work for you around the clock. Only four main parts to assemble and no moving parts that can break down! The collector that attracts the particles is easily removed and cleaned with water and washing-up liquid when needed.

Small & moveable. Fits into any environment.

Lightair strives to respect the environment at all stages of the product life cycle.

LIGHTAIR IonFlow 50 is based on a revolutionary and unique technology and is showing remarkable performance in particles reduction tests of different kinds. The extraordinary performance is mainly due to the ability to generate enormous amount electrons forming a corresponding quantity of negative ions and to efficiently collect particles from the air. As far as we know no other air purifier has never before reached this high number of negative ions without serious side effects such as generation of dangerous amount of ozone. Compared to traditional air purifiers Lightair is not moving air through a filter to catch the particles, but instead it is moving the actual particles out of the air to a collector with only the natural airflow in a room.


SP (Part of the Swedish Government, Ministry of Industry) has tested a number of the market leading air purifiers in regards to their particle reduction performance of small particles. The test verifies that Lightair IonFlow 50 efficiently removes practically all airborne particles. It is actually as good as one of the best HEPA filter based air purifier, but without the noise, energy consumption and expensive filter change! Please find full test report for download below.


Test reports from several third party governmental testing institutes such as SP in Sweden and VTT in Finland has proved the IonFlow 50 to be ozone free. Ozone has always been a side effect of ionization meaning the higher ion generation the higher the ozone level. This has resulted in inefficient ionizers in order to respect the threshold value of ozone. Lightair is as far as we know the only one who have been able to solve this problem and can attain an extremely high amount of negative ions without any ozone!


Besides the air cleaning capacity of the Lightair purifier, it creates an environment with very high quantities of negative ions in the air. French physicist J Bricard discovered the relation between the electric state of the air and its micro pollution as early as the 50’s. The physical law of Bricard is simple: Low concentration of negative ions in the air equals pollution. High concentration of negative ions equals healthy air. There has been extensive research conducted in many fields of science of the general effects of negative ions. The results show a large number of positive effects on overall health. Find out more about the positive health effects of negative ions.

This benchmark test report shows that Lightair IonFlow 50 removes the smallest and most dangerous particles better then most air purifiers on the market! The test was conducted by SP, the Technical Research Institute of Sweden (Part of the Swedish Government, Ministry of Industry) in Sep 2008.
