If you are looking for a wearable negative ion generator that is small and lightweight, yet high powered and effective, this detailed guide has the top 8 ionic necklace brands on the market in 2020 and why they are recommended.
Also learn how they work, why you’d want one, potential benefits, 3 important factors, and frequently asked questions on travel ionizers at the end of this article.
This new miniaturized ionization technology can create a ‘clean air bubble’ around you wherever you go. It’s important to choose carefully though as there are many bad options if you don’t know what to look out for.
Top 3 Choices If You’re Short On Time
Many hours of research have gone into this review of the best 8 ion necklaces ahead. If you’re in a rush though, here are 3 recommended choices to consider for your personal needs.
- Buriucu Mini Air Freshener: Generates 20 million negative ions per cubic centimeter per second – 1 hour USB charging for 30 hours use – Weighs just 0.7 ounces and dimensions of 1.8 x 0.94 inches.
- Miuopur Air Filter: 20 million anions pcs/cm3 – 90 minutes charging, 10 hours operation – 1 ounce and 2.36 x 1.18 inches.
- Woolalla USB Air Cleaner: 20 million ions per second – 3 hours to charge, 10 hours operating time – 1.5 ounces and 3.15 x 1.34 inches.
There are 5 more alternatives to consider ahead if you are looking for a different design or style to suit you personally. There are also more established and proven personal air purifiers covered here.
How Do Ionic Necklaces Work and What are the Potential Benefits?
These devices are miniature air ionizers, with a chain or lanyard that you wear around your neck, to generate high levels of negatively-charged ions within your breathing space.
They aim to create a clean air bubble around you by clearing the air of pollutants, such as PM 2.5, pollen, mold spores, pet dander, cigarette smoke, bad odors and chemical contaminants like VOCs.
They also work for airborne bacteria and viruses that travel on floating dust particles and microscopic water vapor, a particularly important feature in 2020.
These wearable negative ion generators flood the air with millions of negatively-charged ions that are naturally attracted to positively-charged pollution particles.
As they attach to these pollutants in great numbers they become too heavy to float and drop to the ground or the nearest surface and out of the air you breathe.
Aside from air cleaning, scientific studies show there are many other potential benefits of negative ions, including improved mood and mental clarity with regular exposure.
3 Important Factors to Look for in Wearable Ion Generators
1. Negative Ion Output
These air cleaning necklaces work by generating millions of negatively-charged ions, also known as anions, to combat positively-charged pollutants.
It makes sense then that devices with higher ion generation will be more effective at purifying the air than those with lower outputs.
2. Comfortable to Wear
No matter how well a wearable ionizer works, it’s useless if you don’t have it switched on and wearing it.
Given this, comfort and an attractive style you’re happy to wear around your neck is an important factor.
Make sure you like the look of any negative ion necklace you are thinking of buying. Also check the weight of it, and consider whether you’d prefer a chain or fabric lanyard. If you don’t wear it then it’s a waste of money.
3. Operation time
If you need a necklace ion generator for traveling, particularly for long flights on airplanes, then check the operation time.
8 hours may not be enough when you factor in airports and public transport – both places you’d definitely want these devices to work in.
Top 8 Negative Ion Generator Necklaces in 2020
Amazon is the best place to buy an ion necklace due to the low prices and wide section. However, due to the recent popularity of wearable ionic devices, any search brings up dozens of new brands and unproven designs.
Customer reviews and owner feedback are in short supply and listings come and go quickly, making it difficult to make an informed decision.
In researching and compiling this list of the best wearable ion generators, I’ve consulted manufacturer websites, and in many cases written to them directly, to work out the truth amongst varying claims and specifications.
After a great deal of time and research, I’m confident these 8 are currently the top travel ionizer brands on the market in 2020.
1. Buriucu Air Filter Necklace
The tiny Buriucu may not be the most stylish wearable ionic device on this list. However, my research shows the ion generation quoted, an impressive 20 million ions pcs/cm3, is the most likely to be accurate and effective.
On manufacturer sites and online stores, the listed specifications are consistently the same. Proven mini ion generators, like the excellent ionMi available here for a lower price (without the necklace but still wearable), have the same ionic output so the technology exists.
Additionally, there is an ODSound anion generator being sold online (at an extra $50 retail at the time of writing) with the same design. Their website states this model complies with FCC digital device limits and has a 1-year warranty.
All in all, the compact yet powerful Buriucu wearable ionizer looks like a safe pick amongst a crowded field of unproven competitors.
See it here on Amazon, currently with free delivery. There’s also a video in that link that shows how it works.
- Very high ion output to combat airborne pollution, offensive odors, volatile organic compounds, and floating pathogens, like viruses, bacteria and mold spores.
- The ODSound air purifier product page says this model clears 98.4% of suspended PM2.5 pollutants from the surrounding air.
- Adjustable chain, quick USB charging with the free cable, and long-lasting operation.
- Smaller than it looks. Check the pictures of people wearing it in the link.
- You should not allow the brush ion emitter at the top to touch your skin or you might get a mild shock. Also do not operate it while charging or near running water.
- People with pacemakers, stents, or patients with heart conditions should consult a doctor before using this or any other wearable negative ionizers to avoid possible side effects.
- 20 million negative ions generated per cubic centimeter per second. Works best in a 3-foot radius around the user.
- 60 minutes USB charging for up to 30 hours of use.
- Weighs 0.7 ounces (20g) and dimensions of 1.8 x 0.94 x 0.59 inches.
See the Buriucu here at the lowest price I’ve found online. The ion generation technology in it is impressive for its small size and light weight.
2. Miuopur Wearable Ionizer
The oval-shaped Miuopur is a 20 million ions per second negative ion generator, according to every sales page and manufacturer site I could find.
It’s small in size, light in weight and comes in white, grey, green and pink color choices.
I like the simple and unobtrusive design with no writing or lights and the adjustable conductive lanyard, rather than chain.
The Miuopur ionizer doesn’t run for as long as the Buriucu, with 10 hours operation time from 90 minutes of charging. For most people that should be enough though (it’s not like our phones last that long right?).
Check the price and see pictures, a video, and more details here for this high powered ionizing necklace.
- 20 million anions per second is a high output for such a small device. Ionization technology has come a long way in the 5+ years I’ve been researching and writing about these products.
- By flooding the air with negative ions the Miuopur clears floating contaminants, such as pollen, pet dander, smoke, odors, VOCs, and PM2.5 particle pollution. Airborne germs also become too heavy to float.
- Great price for the high ion generation. USB cable included. Simple design. Lightweight and different color choices.
- 8 – 10 hours of operation time. This may not be enough for some people traveling long distances and for long haul flights. Consider the Buriucu or Oxy-Angel air purifier below for longer run time.
- Some other sales pages for this model show a ‘threading crochet’ and the linked product mentions an included ‘lanyard aid’. This could mean you have to fit the lanyard on yourself.
- New product with very few customer ratings or reviews online. Can also go out of stock or have delayed delivery on some pages so check the ‘Arrives’ date.
- 20 million anions pcs/cm3. Adjust the connecting lanyard closer to your face for best results.
- Takes 90 minutes to charge and works for 8 to 10 hours.
- Weighs 1 ounce (28g) and dimensions of 2.36 x 1.18 x 0.98 inches.
Currently, the Miuopur listing here on Amazon has the best price of this model.
If it’s not in stock then Jinserta and Woolala travel air filters also sell similar designs you can find with a product search.
3. Woolala Mini Air Ionizer
Woolala is a big brand that seems to do a version of virtually every negative ion air filter necklace design on the market.
Unfortunately, I haven’t always found their specifications to be that reliable. With, for example, stated ion generation sometimes much higher than other brands selling the same design.
In the case of this particular travel ionizer, the output Woolala list of 20 million negative ions pcs/cm3 is in line with factory sites which builds trust.
The simple black rectangular design itself looks quite good and you could also have it resting on a table or desk beside you if you didn’t want to wear it around your neck.
Woolala has it at the best price here is also the only company I’ve seen with American stock to delivery quickly.
Their product pictures state that this little ionizer removes 94% of airborne bacteria and 99% of PM2.5 pollution in close proximity. It’s also noiseless, has no radiation, and can be safely taken on airplanes for traveling.
- High ion generation to purify the air of floating pollutants, bad smells, chemical gases, and airborne germs.
- Woolala’s recommendation to wear it when you travel by plane, train or bus, at the gym, in crowded elevators, and at the office, is a good description of how to use necklace purifiers like this.
- Adjustable lanyard, free charging cable, and a design that can rest on a table or work desk if you don’t want to wear it around your neck all the time.
- Competing brands have higher specifications online (which are questionable) and few customer ratings or feedback for this recently released model.
- Longer charging time yet less operation time than the Nulipam or Oxy-Power air cleaners ahead.
- 20 million negative ions per second generated from the brush emitter on top.
- 3 hours charge time. 8 to 10 hours of operation time.
- Weighs 1.5 ounces (43g) and dimensions of 3.15 x 1.34 x 0.73 inches.
At the time of writing, Woolala brand has the best value for this model available here.
If it’s sold out then a search on Amazon for N/O or Formemory should find what looks to be the same design, though specifications can vary.
4. IGOKOTI Ionic Air Cleaner (2020 Upgraded Model)
This recently released necklace purifier is something of a wildcard. I spent a lot of time researching it and am still not 100% sure about it. You can find it here on Amazon to see what I mean.
On the one hand, if its stated negative ion output of 120 million is accurate then it’s more than 10 times higher than the vast majority of wearable ionizers on the market. It’s even comparable to the best negative ionizers for your home.
On the other, websites selling this product have conflicting information, with some exhibiting an obvious lack of knowledge about what negative ions are.
For example, “negative ion concentration: 8000-12000W/cm” is the most commonly stated output for this product online and shown in sales imagery. Usually, anions are measured in millions per second per cubic centimeter (pcs/cm3).
I’d never seen this W/cm measurement before so I asked an ionization expert from Japan his opinion and he didn’t understand the term either. That makes me cautious to recommend this model.
Perhaps it’s just a lost in translation typo and this new 2020 ionic necklace really is that powerful. If so it would be outstanding for the price.
I wrote to both the seller on Amazon and the company I suspect is the manufacturer, asking for proof. I’ll update this review if they provide it and may well move it up to the top pick.
If the meantime, I think it’s safer to conservatively assume this necklace air filter is more like 12 million pcs/cm3. That’s still very high and more in line with competitors in the wearable negative ionizer market.
- Very high ion generation for its small size, whether 12 or 120 million pcs/cm3. These negatively-charged ions attach to floating pollutants and allergens so they become too heavy to remain suspended in the air you breathe.
- Available in silver and black. Long operation time. Stylish design and lightweight at just 1.69 ounces.
- Product images on manufacturer sites state the IGOKOTI has “passed CE, RoHS and FCC certification and complies with international standards”. That also means it’s unlikely to be an ozone generator.
- Conflicting information on various sales pages and brand new mid-2020 product so few customer reviews and unproven track record.
- 3 hours charge time is comparable to some smartphones but still much longer than most competitors. A USB charging cable is included.
- Negative ion concentration: 12000W (this could be either 12 million or 120 million negative ions).
- 3 hours charging time for 30 hours operation on high and 60 hours on low.
- 1.69 ounces (48g) and dimensions of 3.15 x 1.38 x 0.9 inches.
Currently, this mini ionic air purifier is at the lowest retail price here from IGOKOTI on Amazon.com.
If it’s unavailable there then Eva zzy, AirDinbor and Woolala air purifiers also sell this new model.
5. Oxy-Angel Personal Travel Negative Ion Purifier
The diamond-shaped Oxy-Angel was one of the first of the next generation of ion necklaces to appear on the market and became very popular due to concerns about airborne viruses in 2020.
Since it’s been around for longer than any of the other choices in this best wearable air ionizers list, it has also had time to receive far more feedback from users.
With 60+ buyer reviews and a 3.5-star rating on Amazon at the time of writing, it’s not exactly outstanding. You get what you pay for though and the Oxy-Angel is low cost for a 7 million pcs/cm3 ion generator.
This customer feedback is fairly indicative in my opinion: “It works great. I’ve probably ordered about 20 for family & friends. Of all, only 1 was defective – can’t complain about those odds. It would not hold a charge and would turn off after 5 mins. The seller accepted the return so I can’t complain about the customer service.”
You can check its price and availability here and see many more user reviews. The customer Questions & Answers section is also helpful for making a decision.
Some people who purchased the Oxy-Angel complained about long delivery times since this necklace purifier frequently sold out in the early months of 2020.
These stock issues seem to be resolved now with the model available for free delivery within a few days.
- The pendant design looks quite good, though perhaps more appealing for female customers. Keep in mind that these air ionizing necklaces should always be worn above clothing, not under them next to the skin.
- Charging time of 1 hour and lasts for 30 hours on a single charge.
- The seller states that the TSA will allow the Oxy-Angel on airplanes. Since it looks like jewelry it seems less likely to be checked or draw attention on public transport.
- They also say they offer a 30-day return policy with a money-back guarantee.
- Customer ratings are both positive and negative. For some it works well. However, some customers complain about the Oxy-Angel not holding charge.
- Several people give bad ratings for not being able to smell ozone. They are confused though as this is not designed to be an ozone generator and should not emit detectable O3.
- 7 million negatively-charged ions emitted per second.
- 60 minutes charge time for 30 hours run time, according to the seller.
- Weighs 1.2 ounces (34g) and dimensions of 2.1 x 1.8 x 0.7 inches (customer figures as the ones listed on sales pages are clearly inaccurate).
Oxy-Angel is the best-seller in this design and is available here with free USA delivery.
You can find Oxy-Angel on Walmart, eBay, and even a website oxy-angel.com, though these were all more expensive purchasing options.
There are also many brands selling the same design on Amazon, including Nulipam, Mifavor, Breathe Green mini ionizers, and the ever-present Woolala. The later have different color options like blue and pink, though I’m personally skeptical of their listed ion output.
6. Nulipam USB Air Cleaner Necklace
Another popular design in the negative ion wearable market is the circular pendant style you can see here at a low price for the Nulipam air sanitizer necklace.
A feature I do like with this design is the twin ion emitters on either side of where the necklace chain attaches. If one fails then the other could continue working.
Generating 6 million negative ions per second and only an ounce in weight, this USB air cleaner also comes with a free charging cable, gift box, and long and short chain, according to the sales listing.
- Lightweight circular pendant design with 6 million negative ions generated from twin emitters.
- One of the lowest priced ion generating necklaces on the market in 2020.
- As recently as 2019 an anion output of 6 million would have been considered impressive for the size of this ion pendant. Now there are competitors with higher specs.
- Customer reviews are mixed with some saying this product is working well for them. While there are complaints about occasional shocks if worn on the skin and problems operating it.
- 6,000,000 ions pcs/cm3 for this mini portable negative ion purifier.
- 1 hour charge time for 30 hours operation, according to several listings and manufacturer sites.
- 2.36 x 2.17 x 0.67 inches and 1 ounce (30g) in weight.
This is a very popular design and you can see it available here with free delivery within the USA.
There are also versions made by other necklace ionizer brands like Floward, Konren, Shuode, Huidangjia and Blandstrs. Woolala sells it on Amazon in several different colors as well.
You can also find websites selling the PuraSafe anion necklace in the same design for significantly more than these models. Though these sites do have a lot more positive customer feedback.
Cacat Mini Ionizer Portable Air Freshener
This simple silver pendant is the smallest ionic wearable in this guide at just 1.5 inches by 0.6 inches.
Despite its small size it still generates 5 million anions per second and works for 12 hours on an hour of USB charge.
It’s also so cheap to buy here on Amazon you could easily get a second one as a gift for a friend or family member without spending too much.
- Lightweight and inexpensive 5 million ionic generator. Some customer reviews mention high readings when tested with an ion meter.
- Zero ozone, no radiation, and safe for airplanes, according to the manufacturer website.
- Silver pendant design could easily pass as jewelry with no indication it’s an air-cleaning device.
- Being made of metal the Cacat electronic air necklace should not rest directly on your skin or it may give you an occasional mild shock. Not suitable for V-neck clothing.
- Varying operation times on different listings for this mini negative ion generator. 12 hours is most common but some sites state 8 hours. Best to assume the lower number to be safe.
- Check whether this product is ‘In Stock’ and expected delivery date as some customers complain of long waits to receive the product.
- 5 million negatively-charged ions per cubic cm per second.
- 1 hour charge for 8 – 12 hours operation, according to manufacturer sites (free USB charging cable).
- Only 1 ounce (30 g) and 1.54 x 1.54 x 0.65 inches.
If this brand is out of stock you can search on Amazon and find this model sold by Dvluck, Ray-JrMall and Xhring travel ionizers.
HiKiNS Wearable Anion Generator
Like the Oxy-Angel, the HiKiNS necklace is one of the earlier USB-charging air cleaners and ionizers. You can see its unusual shape and check the price here.
There are many more customer ratings and reviews for this model so you can get a good idea of how other people have found using it.
In general though, I don’t think its specifications vs price make it particularly competitive. Especially against the higher-powered travel ion generators in this list, unless you particularly like the teardrop design.
- 3 million negative ions pcs/cm3 and with high and low power mode (though there is no indication from the manufacturer whether there is a difference in ion output).
- Larger and heavier device than most other around the neck negative ion generators on the market.
- The bright blue light, especially on high power mode, seems a waste of battery. One customer complaint mentioned: “it makes you look like Iron Man”.
- Customer feedback is mixed. Some are positive and one person tested it for smoke filtering. While negative reviews mention poor battery life, not charging, and a cheap, plastic feel to the product.
- Several users say they have taken the HiKiNS ionizer on planes, though one said United Airlines refused to allow it. I suspect the bright blue light on the device was the problem there.
- 3 million anions – the lowest output of all the ion air necklace brands listed here.
- Manufacturer and Amazon listings state 48 hours of battery life for 1 hour charging. Customer results often seem to conflict with this figure.
- 4.2 ounces (120g) and 2.95 x 1.97 x 0.98 inches.
Fey-US, HQXHB and others sell this design on Amazon, though they often still have the HiKiNS branding.
I’ve included this model due to its popularity. Realistically though, any of the earlier mini ionizers here look like a better buying choice.
Other Wearable Air Ionizers
I also considered the ReSPR SeLF, Aircleene, Ionie, Dr Kleen, Ionkini, Kerter, BST, TTAA, 100Fixeo, Artibetter, and TLJX necklace purifiers for this guide. A strange bunch of brand names there by any measure.
Based on my research, I don’t think any of these models are worth including above the 8 best negative ion necklaces already listed here.
I will keep an eye on this evolving market and update this review if newer models deserve inclusion. There is still a case to be made though for the tried and proven wearable air purifiers here.
Special note should be made of the PureAir SOLO Personal Space Air Purification as well. This design boasts a “50 million ion wind”, however, the sellers say this is both negative and positive ions. Read that link to understand why this is best avoided.
Can an ionic necklace protect against airborne viruses?
- High concentrations of negative ions attach to floating pathogens, like viruses, causing them to become too heavy to float. Ionizing necklaces will not protect against forceful droplets, such as sneezes or coughs. This makes them not as effective as face masks, especially at close proximity. Please follow CDC advice to minimize risk.
Are air purifier necklaces allowed on planes?
- Whether you can take ionizer necklaces on an airplane depends on the carrier. There is no specific Federal Aviation Administration restriction on carrying personal air ionizers on planes. However, each airline can make its own rules, according to the FAA.
Are there any precautions, side effects, or dangers of wearing ionizing necklaces?
- Wearable negative ion generators may give you a slight shock if worn against the skin, particularly if made of metal. As a precaution, people with pacemakers or stents should not wear ionic devices. Negative ions are not ozone and breathing in anions is beneficial, not dangerous.
What is the effective range of mini ionizers you wear around your neck?
- Most wearable ionic necklaces list an effective range of 3 feet (1 meter). The closer a negative ion generator is to your nose the better it will work.
Can personal mini ionizers keep cold and flu bugs away?
- Negative ion generators reduce airborne germs, including cold and flu viruses, as well as mold spores, pollen, pet dander, cigarette smoke, VOCs and PM 2.5 particle pollution.
I hope this review of the best negative ion necklaces has helped saved you time and made your choice easier.
Many long hours of research have gone into this guide and I will keep it updated with recommended brands as new models enter this evolving market.
To take the benefits of negative ions anywhere though, especially when traveling or flying on a plane, it’s hard to beat these new wearable ion generators from brands like Buriucu, Miuopur, Woolala and Oxy-Angel.
