Clarifion Air Ionizer is an air purification device that’s more affordable than most air purifiers. The brand describes it as a “mini but mighty” air device that can “help keep homes fresh.”

But are air ionizers as effective as air purifiers? Are they safe? How does an air ionizer work? And how do real users rate and describe the effects of the Clarifion Air Ionizer? 

In this article we’ll answer all of these questions and more, as we analyze clinical studies on air ionization to give our take on whether or not it’s a safe and effective option for improving indoor air quality.

We’ll also feature real customer reviews, explain how air ionizers work with an animated video, and provide a cost comparison to show which retailer sells this product for the best price.

Are Air Ionizers Dangerous?

Ionization is a legitimate air purification technology that has been studied in clinical trials.

A medical review published in the International Journal of Molecular Sciences examined the effects of air ionization.

The good news is that air ionizers appear to be effective for removing contaminant matter from air.

Inhalable dust counts were reduced by around 50% with their use, which is a benefit for allergy sufferers, and particulate matter was reduced by over 50%.

Inhaled particulate matter may irritate the lungs and contribute to cardiovascular disease, so this is also a health benefit.

The main health risk of ionizers is their generation of ozone. This compound is made of three oxygen molecules, and “is a powerful oxidant and may seriously harm our health” according to the study authors.

A clinical trial published in the Indoor Air journal found that an ozone-generating air purifier actually increased the number of particulates in the air, and the researchers concluded that “These results add evidence to the potentially harmful effects of ozone generation in residential environments.”

Based on the available evidence, we do not consider air ionizers to be safe if they emit ozone.

Air ionizers may may be effective for reducing airborne contaminants and allergens, but it seems illogical to use an air purification device that can emit oxidants into the air.

It’s unclear to us whether or not Clarifion’s devices emit ozone. We cannot find this information on their website, and we hope that in the future the brand clarifies this, because it's a consumer safety issue. 

How do Air Ionizers Work?

Air ionizers electrically charge particulate matter in the air, which allows the matter to “deposit” on walls, floors and other surfaces, and removes it from the circulating air.

A YouTube video published by the Home Air Guides channel is less than three minutes long and visually represents how air ionizers work:

Are Air Purifiers a Better Option?

Air purifiers have a simpler mechanism of action than air ionizers.

Purifiers physically trap particulate matter in a filter device, similar to how water purifiers work.

High-efficiency particulate air (HEPA) purifiers are well-studied and clinically shown to be effective.

A 2021 medical review analyzed the effectiveness of air purifiers for controlling indoor contaminant levels.

HEPA filtration was found to reduce indoor air particulate matter between 37% and 64% depending on device. No side effects or adverse outcomes were reported.

As we explained in our review of the Air Doctor purifier device, we consider HEPA air purifiers to be the best option on the market for reducing indoor air contaminant levels.

Air purifiers seem to have only upsides: they reduce air pollutant levels while emitting no questionable contaminants into air.

Air ionizers have the downside of potential ozone emission.

Real People Try Clarifion

A TikTok creator named "marywill" had a positive experience with Clarifion:

@marywilhelminah My Clarifion air purifier has been so helpful since I started using it and I can definitely tell a difference! It’s time to get yours, use my discount code “MARYWILHELMINAH” for 15% off! #Clarifion #clarifionpartner #clarifionionizer #clarifiondstx ♬ original sound - marywill

A TikTok creator named “katrinaforeal” claims that the Clarifion purifier was quiet and convenient:

Our Clean Air Purifier Pick

Sans Air Purifier Mini is our top air purifier pick.

The brand uses medical-grade HEPA 13 filtration, and features an Air Quality Index (AQI) reader that shows real-time air quality data indoors.

The Sans purifier also contains activated carbon to capture volatile organic compounds (VOCs) like formaldehyde.

Sans has a decidel (dB) rating of 30, which is significantly quieter than an indoor fan.

Customers Rate Clarifion

Amazon is a better resource for honest customer reviews than a brand's website in our opinion.

At the time of updating this article, Clarifion has been reviewed over 11,000 times on Amazon with an average review rating of 3.9 out of 5 stars

A top positive review from a verified purchaser is from a user named “Kenneth J” who gave the product a 5/5 rating:

“Get this, I sleep with an Apple Watch on to monitor my sleep. The doctor advised me to invest in these watches. Anyway, it is blutooth so it talks to my computer. I looked at my weekly sleep analysis and it looks like I am sleeping an average of 16 minutes more each night since purchasing these ionizers!!! You can't put a price on sleep so I told my doctor and he said ‘whatever you're doing, keep doing it.’” 

A top negative review from a verified purchaser is written by a user named “K.T.” who gave the product a 1/5 rating:

“That's where things got a bit frightening -- the device was HOT to the touch -- not just warm, but enough I had to drop it onto the counter after unplugging it. I was shocked (figuratively, not literally electrocuted)...I got online in surprise and discovered the reviews about it catching fire -- I have ZERO doubt or surprise. I can't imagine if you plugged this in and left it for a month or more -- which it would be easy to do!”

Clarifion Air Ionizer currently has an average review rating of 4.5 out of 5 stars on Google.

Where to Get the Best Price

Clarifion’s air ionizer is sold at a variety of online retailers.

Clarifion's ionizer is around $0.70 cheaper at Walmart than Amazon.

Clarifion Pros and Cons

Here are the pros and cons of Clarifion in our opinion:


  • Should reduce contaminant matter from air
  • Should help purify air
  • More affordable than HEPA filters
  • Mostly positive online customer reviews


  • Ioniziers can generate ozone which is harmful to health 
  • Unclear if Clarifion devices emit ozone
  • Doesn't appear to be clinically tested
  • Brand's website charges for shipping

Clarifion’s Air Ionizer is affordable and may be effective for reducing indoor air pollution.

However, we don’t currently recommend the device, because we can’t confirm whether or not it emits ozone, and some air ionizers do emit ozone.

Medical research suggests that regularly inhaling ozone is harmful to human health.

It seems like a better choice to use an air purifier device than an air ionizer device in our opinion.

Both categories of devices can improve indoor air quality, but air purifier devices use a physical method of contaminant removal, and therefore have fewer health risks and potential downsides.

We hope that in the future, Clarifion more clearly documents whether or not their devices emit ozone, because this seems to be the one piece of information that would be most useful for consumers.
