It removes cigarette smoke and helps me to relax and concentrate on work!
I skeptically decided to order this mobile ion generator as your website says it weights only 48g and runs on 1 x coin shaped lithium battery for 20 days continuously. It works better than I expected. The negative ions remove cigarette smoke and help me to relax and concentrate on work. I feel refreshed even in a crowded train on my way to work as it removes offensive odors. Read more

Air purified by a lot of negative ions - Lightweight body
The wearable mobile negative ion generator AirTamer A302 weighs only 51g, so it is comfortable to wear it around your neck for long hours.
As many as 420,000 (pcs/cc) negative ions are detected at a distance of 32cm away. Very few mobile negative ion generators let you enjoy such a high negative ion count. You can enjoy the fresh air at anytime and anywhere.
Personal air purifier in an airplane
This mobile negative ion generator is great when you are in outdoors or at the office where you cannot install an air purifier. It will protect you from cigarette smoke.
It will work as your personal air purifier when you are in an airplane where the air is not clean. The clear pearl white body allows you to enjoy a negative ion environment anywhere.
Quickly purifies the air
4x higher air purification capabilities than competing products!
Fig.1 shows how 5 air purifiers remove cigarette smoke. While the red line shows the AirTamer A302 removes 98.9% of smoke particles in only 5 minutes,
it takes others 20 minutes or longer (out of the range!) to remove the same amount of smoke particles. Thus, the AirTamer A302 has 4x higher air purification capabilities than competing products.
Incredible negative ion count despite the small body!
Ion count at a certain distance away
Approx. 420,000 (pcs/cc) negative ions are detected at a distance of 32cm away from the blow off points.
You can absorb plenty of negative ions when worn around the neck.
AirTamer's high density ion generation performance ensures high air purification capabilities.
There are many mobile negative ion generators in the market but very few of them let you enjoy such a high negative ion count.
Many of them allow you to enjoy the purified air only when your face is close to the ion blow off points.
High air purification capabilities provided by the specially designed conductive lanyard!
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.
Performance guaranteed by a negative ion specialist with 23 years experience in the industry!
We guarantee the performance as a specialist with 23 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 A302 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)
The AirTamer removes cigarette smoke
The photo below shows 2 hermetic containers permeated with cigarette smoke for 30 seconds each.
You see a lot of smoke in the left container while you see little in the right one. You can see through the right container as it remains almost transparent.
The photo below was taken about 50 seconds after the photo above was taken.
You see very little smoke in the right container as the AirTamer A302 purified the air during the short time period.

Safety design & User-friendly features
Shows you it is generating negative ions
The "ON" indicator on the bottom cover shows you it is working properly. The light purple LED blinks while generating negative ions.
It does not turn on when the battery is flat or the generator is not working properly.
Weighs only 51g
It is designed to run on 2 x coin shape lithium battery (CR2025) to make it lightweight. It weighs only 51g.
It continues to run up to 7 days (+/-) continuously. The batteries will last longer if you turn it off when not in use.
You can adjust the length of the strap depending on your preference.
You can clip it to your pocket and hide it inside, so your neck will not get tired, the device stays at a fixed position and no one will notice it!
There are very few clippable products supplied by others.
No wind noise, Very little ozone generation
No wind noise is generated because it does not have a built-in fan. You can use it in a crowded train.
Many negative ion generators produce a certain amount of ozone.
Ozone is said to be harmful to the human body if its concentration exceeds certain levels.
The AirTamer A302 produces less than 0.05ppm ozone, which is well below the safety standard established by the Japanese Ministry of Health, Labour and Welfare.
No EMI interference - Good in an airplane
This generator does not cause EMI interference. You can turn it on in an airplane.
Electric appliances emit electromagnetic waves.
The AirTamer A302 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
The conductive strap which comes with the AirTamer A302 plays an important role to generate negative ions effectively. The strap is conductive but it is safe to touch it.
This product runs on 2X CR2025.

Q & A
1. 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 A302 back on.
2. How long does it run on 2 x coin cell batteries?
It runs approx. 24 hours/day x 7 days.
3. I have a pacemaker. Can I use this product?
You should consult a doctor before use.
The AirTamer A302 may interfere with the pacemaker function.
4. 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.
5. Is this product water-proof?
It is not. Please be careful especially when raining.
6. 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 take negative ions generated by the AirTamer A302.
7. Will it eliminate the harmful bacteria, pollen, and mold found in most homes or offices?
The AirTamer A302 is designed to be worn around the neck in order to purify the air around you. If you are looking for a negative ion generator which provides wider coverage, the "Mecical Ion Mini" is the option.
8. Should I run my air purifier all the time?
We suggest you should run it 24/7 if you do not mind the cost to replace the batteries every 7 days +/-.
9. Does it need filters?
No, it does not.
10. What are the unique features of your negative ion generator compared with similar models?
The unique features of the AirTamer A302 are:
As many as 420,000 (pcs/cc) negative ions detected at 32cm away
As small as an MP3 player and only 51g
Low power consumption (runs on 2 x coin shaped lithium batteries for 7 days continuously)
Stylish yet simple
11. Do all particles/waste/dust collect inside the machine?
No, they do not. They combine with negative ions and fall onto the floor.
12. Will it protect the wearer from the effects of second-hand smoke?
It cannot remove cigarette smoke completely but we have received many reports that it helps.
13. Do I need to purchase any consumables on a regular basis?
No, you do not.
14. 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 A302 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.
15. Does it generate wind noise?
No, it does not.
16. Why does it have such high air purification capabilities?
Specially designed conductive lanyard & 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 provides 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.
