We are living in uncertain times

Viruses, pollution and allergies have been on the increase and seem to be getting more extream every year.

There seems little we can do to improve our situation?

Viruses mutate rendering vaccination almost useless, pollution is spiraling out of control and our diet and fitness levels weaken our immune systems rendering us more suseptable to allergies & viral infections.

At LightAir we are clean air specialists, through our patented technology we have created IonFlow air purifiers and we are proud to say that our air cleaning devices are considered the best and most effective air purifiers for your indoor environment.

LightAir IonFlow

Life changing Improvement

LightAir makes a life-changing improvement for people with asthma, allergies and COPD, as well as for children, the elderly and the ill, these are the people who are most sensitive to infections, fine particles, and ultra-fine particles.

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.

Our filter-free and silent IonFlow efficiently cleans your air from 99.94% of pollutants such as traffic pollution, mold, smoke, fine dust, pet allergens and more – all the way down to PM0.007.

Scientific research also prove that IonFlow neutralizes over 97% of the virus immediately in your indoor-air, without having to pass through any filter or similar device.

The 7 years long study was carried out by well known scientist at Karolinska Institute, one of the foremost medical universities in the world and awarder of the Nobel Prize in Medicine, and published in Nature, the world’s most highly cited scientific journal.

Provides truly clean air

LightAir gives you the cleanest air you can get! According to the scientific community, size matters.

More than 90% of all particles in the air are smaller than PM 0.1. These particles are the most harmful to your health because they deposit deep into the lungs and enter our bloodstream and affect your inner organs.

This is why fine particles are one of the largest causes of premature death.

According to third-party governmental tests, LightAir IonFlow air purifier remove particles down to PM 0.007 meaning that we keep your air virtually free from harmful particles.

Silent operation- Quieter than a whisper

Your air purifier will not disturb your important work or your precious sleep!

But it will improve your sleep quality.

It will do a better job than the best HEPA air purifier but without a sound!

IonFlow air purifiers work at less than 21 dB(A)! That is less than half the sound of a whisper.

This can be compared to most other air purifiers that tend to have a noise level of 35-80 dB(A) or more.

Energy efficient

Low energy consumption saves both money and the environment!

Thanks to LightAir’s innovative technology the energy consumption of the IonFlow air purifier is only 5W, (about $5 usd/฿150 thb per year), which is extremely low compared to other air purifiers.

Don’t forget that the air stays clean only as long as you do something about it – air purifiers should therefore stay in operation 24/7 to give you clean and healthy air around the clock.

Science says

Filterless- There is nothing to replace

LightAir IonFlow air purifiers are hassle-free and very easy to maintain.

Once your LightAir IonFlow reusable particle collector starts looking dirty, just clean it by rinsing the collector under a tap.

There is no reduced capacity due to clogged up filters, no more ordering new filters and no need for complicated installation of new filters.

And don’t worry, even if you forget to clean your particle collector it will continue to operate just as efficiently.

lightair Ionflow purifiers do not produce ozone icon in blue
Science says

Environmentally friendly - No OZONE

Some air purifiers emit ozone, not LightAir!

Ozone can cause health problems such as asthma, emphysema, and COPD. Ozone has traditionally been a side effect of many air purifiers meaning the higher ion generation the higher the ozone level.

LightAir alone has been able to solve this problem and can generate an extremely high concentration of negative ions, thus a very efficient air purification without ozone.

LightAir removes particles typical HEPA air purifiers can't

Typical HEPA-based air purifiers can remove particles down to 0.3 microns, but 90% of the particles in the air, including the most harmful ones, are smaller than that. Most HEPA air purifiers only catch a fraction of these harmful particles. Our LightAir IonFlow air purifiers use negative ions, not filters, to effectively remove particles all the way down to 0.007 microns.
