Air Purifier Myths Debunked: Part I



Over the years as people have become more and more aware of air quality and how it affects their health, air purifiers have become an increasing part of people’s lives. With that, though, there are a number of myths about air purifiers that have gained acceptance.

We’ve spent countless hours with air purifiers from some of the most innovative companies in the world, and our people have been involved with every part of the air purifier life cycle from R&D and manufacturing to service and sales, and of course, years and years of air purifier use.

We’re putting those hours of experience to work as we bust some of the most common air purifier myths.


Myth 1: An air purifier will magically solve all my breathing problems.

They Do for Many

Air purifiers are life savers for millions of people, worldwide. Those with allergies, asthma, and COPD often experience marked relief when using an air purifier. Once you have an air purifier to remove the irritating particles from the air, your symptoms can improve dramatically, and we have review after review from customers who are stunned by the improvement.

But It's Not A Guarantee

However, that doesn’t mean that an air purifier will 100% cure your respiratory problems. If you still have the occasional allergy or asthma attack, that isn’t necessarily a sign that your air purifier is not working. Instead, be aware of the frequency and severity of your allergy or asthma issues. The overall trend of your symptoms should decrease.

The Difference Is Awareness

Some people don’t realize a significant improvement until the following allergy season rolls around and their allergy problems are significantly reduced from from the prior season. It’s easy to forget that you’ve got an air purifier that’s been quietly working in the corner all year, and to realize that it might be the reason for the “lighter allergies this year” or “sleeping better on most nights”.

Myth 2: An air purifier creates ozone.

Is It True?

15 years ago, Consumer Reports sent a shockwave through the air purifier industry when they announced that the most popular air purifier on the market, the Ionic Breeze by Sharper Image, produced unsafe levels of ozone. This finding was a major catalyst for the $500 million bankruptcy filing a few years later.

Ever since then, the word “air purifier” has been synonymous with “ozone” for many consumers.

Not True Any More

Most air purifiers include an ionizer. Ionizers can produce Ozone. So do all air purifiers produce Ozone?

Ionization technology has come a long way in the last 20 years. These days, the ionizers used do not produce ozone. For extra measure, all air purifiers sold on Air Purifiers America are certified by the California Air Resources Board to be “Ozone Safe”.

And if that doesn’t relieve your concerns, most air purifiers come with a switch that allow you to turn off the ionizer all together.

Try A Unit With No Ionizer: Austin Air Healthmate Air Purifier

One of our most popular chemical and odor purifiers, the Austin AIr Healthmate is able to remove significant volumes of toxic vocs as well as airborne particles. It doesn't use an ionizer to boost its performance, so even if ionizers are tainted in your opinion, you have nothing to worry about with this top performer.

Myth 3: All air purifiers work more or less the same.

Are All Cars The Same?

This is kind of like saying “all cars work the same.” While all cars can get you from point A to point B, very few people would put a Honda Civic in the same class as a Tesla Model S.

The Technologies Can Differ

When it comes to cleaning the air, there is a wide array of technologies used on the market, including some that promise a lot but do very little, if anything.

HEPA Is Most Trusted

Air Purifiers America promotes air purifiers that utilize a HEPA filter because HEPA filters provide the best filtration effectiveness out of any technology on the market.

Ionic Only Units Are Popular, But Less Effective

Some promote ionic air purifiers, which do not have filters or fans as being much quieter or more cost effective. However, these purifiers remove a far smaller percentage of the pollutants in the air and often do not cover large areas.

AVOID Ozone Generators!

Some even market ozone generators as air purifiers due to their ability to make the air smell fresh. Ozone is an irritating pollutant, so we recommend that you avoid these at all costs!

Air Purifiers Can Differ Significantly

Looking beyond these three main filtration technologies, there are still dozens of other features and functions that air purifiers can employ to improve their performance and effectiveness for specific concerns.

Air purifiers are definitely not all the same, which is why we provide many recommendations depending on what your needs are. Check out our Top 10 list if you want to see the air purifiers that we believe do the best job overall.
