More Info

The LightAir IonFlow 2.0 Evolution silently protects against airborne infections

The IonFlow 2.0 Evolution is our best-selling silent and filter-free air ioniser! It cleans the air from the most harmful particles – fine, ultra-fine and nanoparticles down to PM 0.007 using the proven, patented ultra-high-density ionisation technology that is used primarily for people with lung diseases such as COPD and asthma. It works great in all home and commercial environments up to 50 m2

Instantly eliminates over 97% of airborne viruses

The LightAir IonFlow 2.0 Evolution air ioniser works by negatively charging the particles in the air. As a result, the positively charged collector attracts the particles in much the same way a magnet operates.

Seven years of scientific research at Karolinska Institutet in Sweden proves that the IonFlow technology neutralises over 97% of viruses immediately in indoor air, without having to pass through any filter at all. If someone sneezes, almost all the viruses are neutralised before they even have time to reach you.  

Also, 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

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


LightAir IonFlow Air Cleaning Technology - Aerify

The filter-free and silent IonFlow 2.0 Evolution efficiently cleans your air from 99% of pollutants down to PM0.007. 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. Hence, it is crucial to choose an air purifier that effectively removes nano-level particles.

The unparalleled air purifying ability of the IonFlow 2.0 Evolution makes it an efficient solution for allergies, asthma, COPD, pregnancies, infants, children or anyone looking for a healthy lifestyle.  

Uses ozone-free and CARB certified technology

The IonFlow 2.0 Evolution is equipped with a unique and patented technology that produces around 30 billion negative ions per second at a one-meter distance from the air purifier without releasing harmful ozone.

The ozone emissions of the IonFlow 2.0 Evolution are not measurable (below the detection level of 0.002 ppm). Being ozone free is a unique feature that any other ionisation air purifier does not probably match on the market.

The IonFlow 2.0 Evolution is 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.  

Virtually silent operation allows you to enjoy healthy air without distractions

The air purifier is exceptionally quiet. Put it in a bedroom or an office and it will not disturb anyone. It operates at only 21 dB(A) - lower than a whisper in a library! 

Anything above 45 dB(A) is perceived as counterproductive and annoying. Being virtually silent makes the LightAir IonFlow 2.0 Evolution the ideal air purifier for a bedroom or office - the rooms where we may spend the longest time on average per day. 

Uses very little power, no fans and filters to replace

The IonFlow 2.0 Evolution features a reusable particle collector that you can quickly rinse with water and use again and again. That you never need to change or buy filters will save you a lot of money compared to conventional filter-based air purifiers. Add the environmental aspect and low electricity costs, the entire world is a winner!

Based on the IonFlow 2.0 Evolution consumption of 7 watts and the average use time of 10 hours per day, it costs around 45 pence to run the air purifier for a month or approximately £0.0015 per hour. 

Simply plug the air purifier into a power socket, and the device will do the work 24 hours a day.

What You Get

1 x The LightAir IonFlow 2.0 Evolution air ioniser


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. The collector should be cleaned approximately once every two weeks but may require more frequent cleaning if used in highly contaminated environments.

Does the air purifier come fully assembled?

The air purifier requires some simple assembly. 

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). The Air Resources Board has also tested and approved it 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. 

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. 

Do I need to use the protective guard?

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

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.  

What is the manufacturer's guarantee on the IonFlow 2.0 Evolution air purifier?

The guarantee is 12 months and is given by the manufacturer - LightAir.

Don't know if it really makes the difference

Besides undoubtable pros (no filters, silent, aesthetically pleasing), I can't really say if it makes the difference with the air quality of your house. It does grab dust and small particles, but still see the air full of dust in the house and notices no difference in breathing.
I think is does a good work but can't say if it's also enough. Price is quite high, and in my case I had to replace the upper part because after a few months it stopped working (since I bought it from a supplier of the company I work for, they replaced it for free).

Feel a lot safer going back to the office

I now feel a lot safer going back to the office and they seem to be picking up a lot of dust. They are very quiet and you hardly notice them once they are switched on.

Philip Tourtel

Unfortunately it's the sort of product which is difficult to know if it is improving our air quality. Perhaps a longer period of assessment will be needed. Also the circular trim item was very fiddly to put together and for the sake of a slightly larger box and the cost of the item, I believe it should come pre-assembled.

Very happy with it, sneeze less frequent now

The main reason why I went with the Swedish Evolution is that it is virtually silent so I can sleep with it on and not worry about the noise. Also, it doesn't require any filters at all. All you need to do is wash the collector with water roughly every 2-3 weeks. I sneeze less frequent now, very happy with it!
