What Is the Function of an Air Purifier Necklace?

Most people may be baffled by the variety of air purifiers on the market today. Among these items is an air purifier necklace. However, what mainly is the function of these purifying necklaces?

Small, wearable air purifier necklaces have become popular due to their capability to guard against viruses and other pollution. In addition, since they’re so compact, they’re easy to take with you.

I’m aware that the response above may not provide you with all the information you’re looking for. For this reason, we’re going to take a closer look at wearable air purifiers and how they function.

Wearable Air Purifier Necklaces: What Are They?

Necklace-style air purifiers operate differently than standard household air purifiers. For example, they frequently employ ionizers and ionization technologies to filter contaminants from the air. On the other hand, most non-portable home air purifiers utilize HEPA filter technology to eliminate pollution.

Each minute, wearable ionizer purifiers emit thousands of ions into the air. These released ions combine with contaminants in the air, imparting a static charge. Like a statically charged balloon adheres to a wall, charged particles are more likely to stick to whatever is nearby.

Personal Air Purifiers: Are They Effective in Preventing the Spread of Viruses and Other Pollutants?

Scientists in China and California conducted a study to determine the efficacy of four wearable ionizer air purifiers. Each air purifier necklace was placed in a 0.46m3 (16.24 ft3) chamber approximately the size of a dog kennel.

They determined the effectiveness of each portable air purifier in removing microscopic particles from the air. The outcomes were: Three of the four wearable ionizers tested eliminated less than 10% of particles located 20 cm (0.1 ft) away.

10% protection is inadequate and significantly less than the 95% virus protection provided by wearing a mask. Additionally, these tests of personal air purifiers were conducted in a tiny enclosed chamber measuring 0.46m3 (16.24 ft3). Therefore, it’s conceivable that these wearable air purifiers will perform even worse in the real world when worn.

Air Purifier Necklaces Can Be Dangerous to Your Health  

Along with research demonstrating that wearable purifiers are ineffective at purifying the air, there are further problems:

Wearable Air Purifiers Produce Ozone

Numerous studies have shown that wearable air purifiers can generate ozone by using an ionizer rather than a HEPA filter. However, ozone is toxic to humans and can cause lung damage.

The precise amount of ozone generated by each personal purifier varies considerably. Nonetheless, the average consumer has no means of knowing for certain. Each ionizer produces a different amount of ozone, but some have emitted hazardous levels.

Certain marketers have attempted to convince consumers that the ozone generated by ionizers is different from other ozone and thus harmless. Unfortunately, this is not true, as the EPA clarifies.

Air Purifiers Interfere with Personal Care Products

The ozone created by air purifier necklaces may pose major health hazards. Studies have shown that it reacts with terpenes found in personal care goods such as lotions, perfumes, and cosmetics.

These ozone interactions can produce hazardous volatile organic compounds (VOCs) such as formaldehyde, as well as PM2.5 particulate matter. All of this would occur in the brain region.

Pollution Can Stick to Your Face and Clothes When You Wear an Air Purifier Necklace

Ionizers function by attracting pollution to adjacent surfaces, which traps it and removes it from the air. However, there is an issue if the nearest surface is your body.

When you wear an air purifier necklace, your face, body, and clothing serve as a magnet for pollution. This can result in soiled clothes and skin and inhaling more contaminants than you would normally.

Easy Ways to Determine Whether Your Air Purifier Is Working

The following are the ways you can determine if your air purifier is operational:

Evaluate the Airflow of Your Air Purifier

Checking the airflow out of your purifier helps determine if it’s functioning properly. Air purifiers utilize a fan to pull in air from the surrounding area.

Purifiers filter harmful contaminants from the air and then blast out clean air. If the purifier is turned on but doesn’t blast out any air, it will likely not operate properly.

Additionally, you can use the fan inside the air purifier to determine the purifier’s status. Ideally, the fan shouldn’t be working excessively hard to draw in and blow out air.

Your air purifier may need a new filter, or another issue may be underlying the noisy fan. Similarly, if your air purifier is silent, it is generally not drawing in enough air to improve your indoor air quality.

Examining the Air Purifier’s Filters

A clogged filter is amongst the common causes for your air purifier to stop working. Purifiers clean the air by forcing it through a filter that catches pollen, mold, and other pollutants. Unfortunately, the filter will eventually become blocked and may require replacement.

While some cleaners include a filter service indicator that alerts you when it should be replaced. Most of these indicators are timers that alert you when the recommended time frame for filter replacement has gone. Nevertheless, your filter will not last as long in heavily polluted locations and will need to be replaced more frequently.

When inspecting the filter, look for discoloration or black patches. In general, if the filter appears unclean, it should be replaced.

A filthy purifier can even become a source of pollution, blowing germs, molds, and particles back into your home. However, numerous contaminants are imperceptibly small, and any filter damage may be minuscule. 

Using an Air Quality Monitor to Assess Your Purifier

Utilizing an air quality monitor is one of the most effective methods of determining the efficiency of your air purifier, regardless of its type.

The test is straightforward:

First, take a baseline reading of the air quality with the purifier turned off, and then switch it on. Any change in air quality can be ascribed to your purifier when all windows and doors are closed. You may either set the air quality meter near the purifier’s vent or in a room where you frequently use it.

Depending on the scale and form of the space, your cleaner should restore healthy air quality within 30 minutes to a few hours. If your cleaner runs for an extended period with little to no improvement in air quality, you’ll know it’s not working.

The information above is useful for more than just checking your purifier. For example, many believed operating their purifiers for 30 minutes would do the trick. However, after the test, they discovered that they would likely need to operate their cleaner to cleanse the entire room for much longer.

How Effective Are Wearable Purifiers Against Viruses?

Air purifiers using wearable ionizers are poor at cleansing the air. Additionally, these portable cleaners generate ozone, which might have a detrimental effect on the health of those who use them.

What is the Function of Air Purifier Necklace?

Small, wearable air purifier necklaces have gained popularity because of their ability to combat viruses and other forms of pollution.

How Do You Turn on an Air Purifier Necklace?

The air purifier necklace is quite simple to operate. Press down the power button for three seconds to power it on, and the indicator light will flash green to signify that it is operational. The air purifier necklace operates quietly for 10 to 12 hours on a full charge.

What Are the Benefits of an Air Purifier Necklace?

The following are some of the advantages of air purifiers:

  • Taking steps to eliminate hazardous substances from indoor surroundings
  • Reduces the risk of contracting airborne infections
  • Eliminates dangerous radon
  • Enhances Sleep Quality
  • Eliminates harmful asbestos particles

Is an Air Purifier Effective in Treating Asthma or Allergies?

Air purifiers don’t treat asthma or allergies but help prevent the symptoms by filtering out allergens in the air. Therefore, purifiers are primarily used as a preventative strategy and not a treatment method.

Are There Any Negative Effects of Using an Air Purifier?

In general, there are no adverse consequences. Nonetheless, a few cleaners on the market employ electrostatic precipitators and ionizers; these devices may release trace amounts of ozone. So before purchasing an air purifier, it is critical to review the product specifications.

How Much Does an Air Purifier Cost to Operate?

It’s contingent upon a few factors. For example, power is a secondary expense of running an air purifier. However, the device’s energy efficiency will affect its running costs.

Additionally, you’ll need to purchase replacement filters from time to time. For instance, if you get a high-quality HEPA filter, it should be replaced every 3-5 years. There are less expensive filters available, but they are less effective and require more frequent replacement.


Demand for air purifiers has increased due to inadequate ventilation in households. They help reduce indoor air pollution, but their filters have a limit.

Certain filters are good for two to three months, while others last longer. Continue to monitor the air filter indication to ensure that you replace filters on time and maintain a clean indoor environment.
