Air Science

This is not traditional air purification. This is the future. Delivered today.

We believe that the reason you are here is because you are trying to find the best solution to improve your health. We all know that clean air is essential to good health and that it’s a basic human need. But how would you define clean air?

We have to get a little technical here, in order to explain what clean air really is. Particulate matter is everywhere in the air around us. Each and every day, the average adult breathes about 20,000 liters of air. Thus, when you inhale, you breathe in any particles that are in the air, whereof most are invisible to the naked eye. With numerous pollutants in most indoor air that affect your health – such as pollen, mold, smoke, fossil fuel pollution, pet allergens and viruses – it’s increasingly important to purify the air. On this page we will explain to you how and why our technologies are the best way to do this.

IonFlow and CellFlow – Our patented technologies


IonFlow Technology


Removes the smallest and most harmful particles, down to PM0.007.

Only air purification technology scientifically proven to neutralize and remove 97% of all virus in the air

Completely silent for undisturbed work and sleep.

Filter free and minimal energy consumption – a great solution for both you and our planet.

With unique technology, we do it better

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. Learn more HERE.


LightAir neutralizes 97% of viruses

LightAir IonFlow air purifiers offer unmatched protection against viruses, which HEPA-based filters don’t deal with. IonFlow air purifiers attach negative ions to viruses, making them harmless (not contagious) already when in the air. The 7-years long scientific study involved is explained HERE.


We welcome comparisons. See how we measure up.

Our IonFlow air purifiers don’t just clean the air better and offer more virus protection than any regular HEPA filter can. They are also virtually silent, use less electricity and have annual operating costs close to zero compared to more than $500 a year for less effective HEPA filter systems.


Virtually silent, IonFlow air purifiers won’t disturb your sleep or your concentration. Operating at 21 decibels (compared to 35-80 decibels for HEPA filter systems), they cannot be heard above normal background noise.


At full power, IonFlow air purifiers use only 5 watts compared to 60-175 watts for typical filter-based air purifiers. Since the air stays clean only as long as you do something about it, air purifiers should operate 24/7.


There’s nothing to replace and no need to ever buy an expensive filter again. Just rinse LightAir’s reusable particle collector in water. This will save you $50-400 per year compared to filter-based air purifiers and is also great for the environment. Combined with lower electricity costs, savings can go into the hundreds of dollars per year—enough to pay for a second IonFlow air purifier.
