About IonFlow 500

IonFlow 500 is designed to blend in with any office or commercial decor, with a modern, silver/gray color scheme and hand-crafted acrylic base.

Independent testing shows that our filter-free, ozone-free, silent IonFlow air purifiers neutralize 97% of viruses and effectively remove 99.94% of fine and ultra-fine particles such as traffic pollution, mold, smoke, fine dust, virus, pet allergens and more all the way down to 0.007 microns—the most dangerous particles of all and far too small for typical HEPA air purifiers to handle effectively. Read the ultra-fine particle reduction report HERE.

If you really want cleaner air, why stop at 10%?

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 make you feel better. Learn how.

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.

This is how it works.

We do it differently. This is the new generation of air purifiers.

1. Generating billions of electrons per second that transform into negative ions.

2. The negative ions charge the particles, such as virus, traffic fumes, smog, pollen, mold, etc, negatively.

Cleaner air in every breath they take.

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

    Verified Purchase

    I love the Ion Flow 500 and ion flow evolution.What great products

    i highly recommended these products
    Its so easy to clean the metal collector,I clean it on average every 2 weeks.
    i have it in the lounge room/kitchen area,also bought the ion flow evolution for my bedroom.
    people would be so surprised if they only knew what they were breathing it without one of delivery from sweden to australia,only took a couple of days
    will be buying another one soon

    Stylish and quiet

    This air purifier is very quiet, no noise at all when I sleep. I live in China and within a few days the collector became dirty, it is easy to clean. I also like the design very much!

  3. bcangela

    Pleasantly Surprised

    This air purifier worked great! It is the perfect size to fit anywhere and is super quiet. It was really easy to setup. I noticed a difference really quickly. Would definitely recommend this product to others.

    I am extremely grateful.

    I have been asthmatic all my life and unfortunately live in the east end of London where there always seems to be building work going on.

    Over the years I spent a small fortune on air cleaners that need replacement filters, although cost was an issue of constantly replacing the various filters. My biggest concern was that no matter the design, dirt would accumulate on the fan blades and eventually circulate the dirt.

    So 7 years ago I purchased what was then called a LightAir cleaner for our bedroom because it had no moving parts. I was shocked at the amount of dirt and particularly dust that it collected, and once a week would wash the collector.

    Unordinary after seven years of 24/7 service it stopped working and with no LightAir rep in London, I contacted the main office in Sweden. Without hesitation they offered to replace the faulty unit. What an incredible service , I am extremely grateful.

    I have a house full of smokers, and it’s sometimes over bearing to company. So, I bought one of these, and now I get no complaints, and that my house has smelt fresher than ever, and the air is breathable, and clean.

  6. dansedufeu

    useful and beautiful

    This thing really works! The dust collects for about two weeks before I have to clean it.

  7. Kristopher Thomas

    starsbut for a secondary room it works fine. Will buy a better one in the future

    I bought it based on price, reviews, and appearance. It is not the strongest, but for a secondary room it works fine. Will buy a better one in the future.

    Love purifying my home looks large enough that I can use for most entire house

  9. xiaodan

    Have good air purification function, filter the impurities in the air, and let these present in sight. Convenient cleaning.
