AirTamer A320 White | Personal Air Purifier Necklace

Loading...

Removes airborne pollutants such as cigarette smoke, viruses, PM2.5, pollen, molds and dust mites


✔ High ion delivery capabilities to capture and remove airborne pollutants!

Negative ions capture airborne pollutants such as cigarette smoke, viruses, PM2.5, pollen, molds and dust mites to remove them from the air. Air purifiers, which release negative ions, use this principle and they need to have enough ion delivery capabilities to perform as air purifiers. The AirTamer A320 has high ion delivery capabilities, so it delivers negative ions to your nose/mouth when you are wearing it around the neck. Thus, you can enjoy the purified air.



You can enjoy beneficial effects as negative ions reach you


✔ Air purification performance determined by ion delivery capabilities

While many mobile air purifiers and ion generators are sold in the market, very few products can deliver ions to the destination.

You cannot enjoy beneficial effects if negative ions do not reach your mouth/nose. Very few users pay attention to this important factor. FYI: How far negative ions travel (How to Choose the Best Negative Ion Generator)

✔ As many as 420,000(pcs/cc) ions at 32cm away!

You can enjoy beneficial effects at a distance away from the AirTamer as it has high ion delivery capabilities which ensure that a lot of negative ions reach the mouth/nose.




High air purification capabilities provided by the conductive lanyard and the nickel chrome plated frame!


Generally, a negative ion generator designed to be worn around the neck is not capable of producing a lot of ions due to the electrical characteristics.

The specially designed lanyard made of a conductive material and the high quality nickel chrome plated frame help the AirTamer A320 to generate a lot of ions and emit them into the air. This is why it has high air purification capabilities. FYI: Why does it have such high air purification capabilities?



✔ Performance guaranteed by a negative ion specialist with 27 years experience in the industry!

We guarantee the performance as a specialist with 27 year experience in the negative ion industry. Actually, some of the products produced by other companies did not meet your requirements due to poor ion distribution. The AirTamer A320 has much higher air purification capabilities than competing products because ions reach you.

We highly recommend this model if wearing a mask does not work. It will surely remove airborne pollutants such as cigarette smoke, viruses, PM2.5, pollen, molds and dust mites. FYI: How far negative ions travel (How to Choose the Best Negative Ion Generator)


Wearing around the neck to enjoy the clean air at anytime and anywhere


✔ Massive ions to purify the air & Lightweight body to wear for long hours

The AirTamer A320 is a mobile negative ion generator. It weighs only 39g (1.3oz). You can wear it around your neck. The lightweight body is good for long hours usage. About 420,000 (pcs/cc) negative ions can be detected at 32cm(1ft) away. You can enjoy the clean air at anytime and anywhere.



✔ Your personal air purifier outdoors, in the office or on an airplane

It removes second-hand cigarette smoke, viruses, pollen and PM2.5 particles outdoors or in the office where you cannot install a stationary air purifier. You can also use it on an airplane where the air is often dirty.


Removes 98.9% of smoke particles in only 5 minutes, purifies the air over 4x faster than competing products


✔ Removes cigarette smoke particles 4x faster than competing products (*1)(*2)

The graph below shows how 5 air purifiers remove cigarette smoke particles.

While the AirTamer A320 removes 98.9% of smoke particles in only 5 minutes, it takes others 20 minutes or longer to remove the same amount of particles.

Thus, the AirTamer A320 purifies the air over 4x faster than others. You can wear it around your neck and it removes cigarette smoke, viruses, PM2.5, pollen, molds and dust mites at anytime and anywhere.

✔ Removes second-hand cigarette smoke to purify the air

The photos below show just after the bottles are filled with cigarette smoke and 30 seconds after that. A lot of smoke remains in the left bottle, while there is no smoke in the right bottle in which the AirTamer A320 is working. You can see through it as smoke has disappeared. (*)





There is no smoke at all inside the bottle. (*)


(*) It takes longer to remove smoke in a room which is much larger than the bottle.

Can be used in two ways at home, in the office and anywhere


1. Wear around the neck

You can wear it around your neck. Please be sure to use the Conductive Lanyard which comes with the generator for maximum performance.



Q: I am going to wear it around the neck and hide it under the shirt during work so that it cannot be seen by others. Does it affect the performance?
A: Yes, it does. We suggest you should wear it so that the blow off point is exposed to the air. You can clip it to your pocket and hide it inside


2. Place on a table/desk

You can place it on a table/desk and use it as your personal air purifier. Negative ions can reach up to 1m +/- away from the device. i.e. You can absorb fewer ions than when wearing around the neck. Please be sure the Conductive Lanyard makes direct contact with the table/desk for better ion distribution.



Comes with convenient/safety features


Indicator light
The indicator light on the back side of the body shows you if the device is working properly. The green light blinks when it is generating negative ions. The light does not turn on when it is not working properly or when the battery is flat.



Rechargeable via USB
It continues to work about 150 hours (6.25 days) after a 3 hour charge. The red light on the back side of the body blinks while being charged.



No wind, No noise, Low ozone concentration
You feel no wind and you hear almost no noise as this product does not have a built-in fan to blow off ions. You can use it in a crowded train.
While many negative ion generators produce a certain amount of ozone which is harmful to the human body, the AirTamer A320 produces less than 0.0001ppm ozone, which is well below the safety standard established by the Japanese Ministry of Health, Labour and Welfare.


Adjustable Conductive Lanyard
You can adjust the length of the Conductive Lanyard.



No EMI interference
The AirTamer A320 conforms to the FCC's (Federal Communications Commission) specifications Part 15 - Class B. This regulation sets exact limitations on the amount of electromagnetic interference (EMI) allowable from digital computing and other electronic devices when used in the home or a residential area.



Cautions before use

  1. The Conductive Lanyard which comes with the AirTamer A320 plays an important role to generate negative ions effectively. It is conductive but it is safe to touch it.
  2. This product can be charged via USB. You can use a USB power adapter for Smartphones or a USB port of a PC. A USB power adapter is not included in the package.


    * You need to get a USB power adapter by yourself.

  3. Consult a doctor prior to using this product if you:
    • are using a pacemaker
    • are under 10 years of age
    • have a history of respiratory problems or heart or lung disease


Q & A


1. How long is the life span of the AirTamer A320?
It will continue to work for about 2 years if you use it 24/7. Mathematically the life span will be about 6 years if you use it for 8 hours a day. Usually it will work longer. You can turn it off when not in use in order to extend the life span. Of course, you can continue to use it after the above-mentioned periods if it is working properly.

The negative ion emitter brush determine the life span. They become worn out as they generate negative ions. You can replace the brush with a new one.

2. How can I clean the unit's exterior?
  • Turn unit off.
  • Gently wipe the exterior with a soft cloth moistened with warm water or mild detergents only. Do not use harsh solvents or chemicals for cleaning.
  • Remove all moisture with a soft, dry cloth.
*Note: Always allow the exterior to dry completely before turning your AirTamer A320 back on.

3. Does it need filters?
No, it does not.

4. Do I need to purchase any consumables on a regular basis?
No, you do not.

5. I have a pacemaker. Can I use this product?
You should consult a doctor before use. The AirTamer A320 may interfere with the pacemaker function.

6. Does this product produce ozone? If it does, is it harmful to the human body?
It produces less than 0.0001ppm ozone. It is not harmful at all.

7. Can I use this product in an airplane? I am afraid it may cause EMI interference.
This generator does not cause EMI interference. You can turn it on in an airplane. Electric appliances emit electromagnetic waves. The AirTamer A320 conforms to the FCC's (Federal Communications Commission) specifications Part 15 - Class B.

8. Is this product water-proof?
It is not. Please be careful especially when raining.

9. What is the power supply?
This product can be charged via USB. You can use a USB power adapter for Smartphones or a USB port of a PC.

Please note: A USB power adapter is not included in the package.

10. How long does it work once fully charged?
It continues to work about 150 hours after a 2-3 hour charge.

11. Does this negative ion generator come with a warranty?
We offer 2 years warranty.

12. Can you repair it if it does not generate negative ions after the warranty period expires?
We can repair for a fee. Please contact us.

13. Why does it have such high air purification capabilities?
Specially designed Conductive Lanyard/High quality Nickel Chrome Plated Frame and High efficiency electrical charge process
We have measured ion counts of many mobile negative ion generators since 1996. Most of them generate fewer ions than the manufacturers claim. Some products generate no ion at all!

This is because it is hard for mobile generators to obtain a good grounding effect. A negative ion generator cannot convert electric power into negative ions effectively without good grounding.

The AirTamer has solved this technical problem. The specially designed Conductive Lanyard & the high quality Nickel Chrome Plated Frame provide a good grounding effect and the high efficiency electrical charge process technology dramatically improves ion generation efficiency. This is why this product generates a lot of ions and has higher air purification capabilities than others.

14. Do I have to wear around the neck when in use?
You can place it close to the body instead of wearing around the neck. It generates fewer negative ions but you can still enjoy negative ion effects.

15. Does it generate wind noise?
No, it does not.

16. I often wear a flu mask. Are negative ions absorbed before reaching my nose/mouth?
We do not have exact data but it has been said that a certain amount of negative ions permeate through cloth. However, a lot of negative ions are absorbed by the mask. We suggest you should expose at least the nose to effectively take the negative ions generated by the AirTamer A320.

17. Will it protect the wearer from the effects of second-hand smoke?
It cannot remove cigarette smoke completely but we have received reports that it helps.

18. Do all particles/waste/dust collect inside the machine?
No, they do not. They combine with negative ions and fall onto the floor.

19. Do negative ions have an effect on odors? My co-worker wears a very strong perfume will this device help remove the offensive smell?
The AirTamer A320 does not provide wider coverage. It will not remove the smell completely. If you are looking for a negative ion generator which provides wider coverage, the "Medical Ion Mini" is the option.

20. Is it true that no purifier can actually effectively remove industrial/transport pollution as the particles are too small?
The AirTamer A320 can remove small particles. Negative ions emitted by it and small particles combine together and fall onto the floor to remove the particles from the air.

21. What does pcs/cc stand for?
It stands for the number of negative ion molecules contained in 1cc.

22. What's the price if I buy two/bulk?
Please contact us if you are going to purchase 10 pcs or more as we can offer discounts.
