  See IonFlow technology in action:

The LightAir 2.0 Signature actively finds and eliminates over 97% of viruses while they are still in the air. Additionally, it captures the most harmful air pollution particles, down to 0.007 microns in size. Under normal circumstances, these nanoparticles represent 90% of all particles in the air and are thought to cause the most severe respiratory illnesses and diseases.

The IonFlow 2.0 Signature works silently as it doesn't have a noisy fan. This makes it an excellent choice for bedrooms, offices and other places where excessive noise can become an issue. Last but not least, the air purifier consumes very little electricity, and you don't need to buy any replacement filters either, which are both economical and environmentally friendly. Simply plug it in, turn it on and let the IonFlow 2.0 Signature clean the air you breathe!

  Excellent choice for:

  • Shoppers with spacious rooms up to 60 m2

  • Those who seek protection from airborne viruses and bacteria.

Air Purifier Expert's Opinion - Aerify

"I like the IonFlow 2.0 Signature for its award-winning Scandinavian design. The high-density ionisation technology neutralises harmful nanoparticles down to an impressive PM 0.007 killing viruses while they are still in the air. It is super cheap to run, there is no filter to replace, and it is practically silent." - David, customer support.

More Info

Instantly eliminate over 97% of airborne viruses

The IonFlow 2.0 Signature air ioniser works by negatively charging the particles in the air. The positively charged collector, which you can simply wash in the water, attracts these particles like a magnet.

Seven years of scientific research at Karolinska Institutet in Sweden proves that the IonFlow technology can neutralise over 97% of viruses immediately. If someone sneezes, the IonFlow 2.0 neutralises almost all the viruses before they even have the time to reach you.  

Additionally, the Swedish National Test and Research Centre and other independent research agencies show that the LightAir IonFlow air purifiers capture over 99% of all airborne particles, including ultrafine particles, bacteria and viruses, pollen and pet dander, traffic pollution, mould spores and fungi.

Eliminates the most dangerous particles down to 0.007 microns

Conventional air-purifying solutions only handle particles larger than PM0.3 and cannot deal with the most dangerous air particles, hence only addressing 10% of harmful indoor air pollution.

LightAir IonFlow Air Cleaning Technology - Aerify

The IonFlow 2.0 Signature produces around 30 billion negative ions per second. This high-density ionisation enables it to clean your air from 99% of pollutants down to the most dangerous air particles 0.007 microns in size. Under normal circumstances, these nanoparticles represent 90% of all particles in the air and are thought to cause the most severe respiratory illnesses and diseases. 

The unparalleled air purifying ability of the IonFlow 2.0 Signature makes it an efficient solution for people living with allergies, asthma, COPD, or anyone looking for a healthy lifestyle.  

Uses CARB certified ozone-free technology 

The ozone emissions of the IonFlow 2.0 Signature are not measurable (below the detection level of 0.002 ppm). As a result, it was certified by the California Air Resources Board (CARB). To be approved, air purifiers must be tested for electrical safety and ozone emissions, and meet an ozone emission concentration limit of 0.050 parts per million.

Silent operation for clean air without distractions

Anything above 45 dB(A) is perceived as counterproductive and annoying. The IonFlow 2.0 Signature is perfect for quiet environments such as bedrooms, living rooms and offices. It operates at only 21 dB(A) - lower than a whisper in a library!

Filterless design and low running costs

With IonFlow 2.0 Signature you will never have to buy or change filters, full stop. The air ioniser has a washable particle collector that you can simply rinse with water every two weeks and use again and again. This will save you a lot of money if you were to buy a conventional filter-based air purifier. Standard HEPA filters cannot be recycled and around 6,000 tonnes of these are sent to landfills every year! 

Running the IonFlow 2.0 Signature 24/7 will not break the bank either. It only consumes 7 watts of power, much less than conventional HEPA based air purifiers.

LightAir IonFlow Power Consumption - Aerify

Luxury Scandinavian design in three colours

The IonFlow 2.0 Signature takes little space and has a modern Scandinavian design that will look great in any room. The switchable LED lighting makes the air purifier an attractive object that effortlessly adapts to any interior.

  • Can I keep the IonFlow turned on 24/7?

    In indoor environments, the air is exchanged continuously.  It will not remain free from pollutants unless the air purifier is on.  Since the IonFlow is virtually silent and extremely energy efficient, we recommend leaving it on at all times.  

  • Do I need to use the protective guard supplied with the air purifier?

    No, the protective guard is optional and not necessary from any safety perspective.

  • How do I know if the air purifier is working?

    When you turn on the air purifier, the blue LED light on the top will light up and the particle collector will become static. The collector will become dirty on the outside. How fast depends on how polluted the environment is where the air purifier is placed.

  • How safe is the air purifier?

    The IonFlow has been tested by third-party institutes and organisations in order to ensure that it meets all current regulations and legislation around the world. Negligible ozone - ozone emission has been tested and approved by the Finnish VTT Technical Research Centre where the test result was not even measurable (instrument measures down to 0.002 ppm).  It has also been tested and approved by the Air Resources Board in California (ARB). Electric discharge - the electric discharge that can be felt when you touch the collector is completely harmless.  Electromagnetic field - the electromagnetic field has been tested and approved by Intertek. 

  • Does the air purifier come fully assembled?

    The air purifier requires some simple assembly. 

  • Is the particle collector washable? How often do I need to clean it?

    The particle collector is reusable and can be easily rinsed in water and used again and again. How often you need to clean the collector depends on how polluted the environment is where it is placed. In general, the collector should be cleaned approximately once every two weeks but may require more frequent cleaning if used in highly contaminated environments.

Clean air

Excellent device the house smells much less doggy!!!!

A Fa
Very pleased with the purchase

I am very pleased with this air ioniser. It is whisper quiet, consumes almost no electricity and looks amazing in our living room. The air feels cleaner inside the room and after a while, you notice a buildup of dust and larger particles on the collector. You only need to rinse the collector every 2-3 weeks to get rid of the dust. The ioniser does require some simple assembly, although I would say the guard is a bit fiddly to put together and can be broken if not careful. Overall very pleased with the purchase.
