  We have found many personal air purifiers that we could have offered for sale, but you wouldn't have wanted any of them.

  Before we found this one, all we found was junk.

   Some of them only emitted ozone, or even undesirable positive ions. (No kidding).

   So, in keeping with our unchangeable way of doing business that the customer comes first ahead of profits, Comtech Research has not made a personal air purifier available - until now.

We've been looking for a good Wearable Air Ionizer like this one for many years.



Finally, we've found a Personal Ionizing Air Purifier that actually works.

The model A300 is being replaced with the improved A302.

Air Tamer A302

The new A302 AirTamer® has DOUBLE the negative ion output.


  • This effective personal wearable travel negative ion generator is exceptionally well-designed and built.
  • Longest battery life AND highest negative ion output of any wearable ionizer.


    The people that designed and built this ionizer actually understand what is really important in a Wearable Ionizing Air Purifier!

    After evaluating many others and testing this one, Comtech Research is proud to finally make a superb portable ionizer air purifier available to you.



  • Protects against harmful airborne pollutants and germs.
  • Breath cleaner, healthier air - everywhere you go!
  • No filters to buy or clean.
  • A302: Over 21 days battery life if operated 7 days a week for 8 hours or 7 continuous days of run time on two batteries.

Wearable personal ionic air purifier - AirTamer A-300

"Letting you know that after receiving the ionizer a few weeks ago, I am completely satisfied! Finally, a portable high-output negative ion machine which is really low profile, (looks like an MP3 player) and has long battery life! I find it surprising the output of this little machine resembles that of a high-density home machine. You are absolutely correct in that this is a very powerful negative ionizer! "

Section 2: About Your AirTamer®

Your AirTamer A300 uses advanced ionization technology to protect you from super-small, atomic-sized particles, such as bacteria, mold and viruses, which are often the most hazardous to your health. Emitting a constant stream of healthy negative ions, AirTamer causes pollutants in the air to become negatively charged, forcing these pollutants from your personal space and creating cleaner, healthier air to breath everywhere you go. AirTamer is completely safe to leave on as long as you like - even 24 hours a day.


Section 3: Description

  • Pocket/Shirt Clip
  • Negative Ion Emitter
  • Conductive Cord
  • Battery Cover
  • Coin Cell Battery (CR2032)
  • Integral Stand
  • On/Off Switch
  • "On" Indicator


Section 4: Setup

Install Battery

One CR2032 coin cell battery is included with your AirTamer. To provide power to your AirTamer, please install the battery as follows:

1. Slide off the BATTERY COVER.

2. Insert the included CR2032 coin cell battery into the battery compartment with the positive (+) side facing up.

3. A new battery will provide approximately 22 days of continuous 24 hours per day cleaning. When the flashing blue "ON" indicator no longer blinks, it is time to replace the battery.


Conductive Cord:

A unique CONDUCTIVE CORD is attached to your unit, which significantly increases the output of negative ions.

The CONDUCTIVE CORD is permanently attached to the unit and incorporates a safety "break away" feature that disconnects the CONDUCTIVE CORD from the unit in the event that the unit gets caught.

Note: for best performance, ensure that the CONDUCTIVE CORD touches your skin when your AirTamer is worn. AirTamer will still work when the CONDUCTIVE CORD is not touching your skin (e.g. when the CONDUCTIVE CORD is coiled up inside your shirt pocket), however, negative ion production will be reduced.


Section 5: How To Use

Using your AirTamer:

1. Turn the unit on by sliding the ON/Off switch to the ON position. A steady stream of negative ions will be emitted from the NEGATIVE ION EMITTER thereby creating a clean zone of healthier air within your breathing space. A blue light will gently blink to indicate that power is on and the unit is cleaning your air.

2. You may use the unit in any of the following ways:

  • A. Suspended from Your Neck.
  • B. Clipped To Your Shirt, Blouse or Pocket.
  • C. Placed On a Nearby Table, Seat or Night stand.

Note: When placing the unit on a table, seat, night stand, etc., place the unit in an upright position (with the NEGATIVE ION EMITTER facing up) or on its back (with the NEGATIVE ION EMITTER facing you). Cover as much of the table as possible with the CONDUCTIVE CORD to improve ion generation.

3. Slide the ON/Off switch to the Off position when you are finished using.


Air Cleaning Performance:

1. This is a personal breathing space air purifier. It is Most effective in areas approximately 3 feet from the unit.

2. This unit is safe to leave on as long as you like - even 24 hours per day.


Section 6: Tips To Improve Performance

1. Ensure that the NEGATIVE ION EMITTER is pointed toward your face during use.

2. If you clip the unit to your shirt, blouse or pocket, suspend the CONDUCTIVE CORD from your neck (with the cord touching your neck) to improve ion flow.

3. If placed on a nearby table, place the CONDUCTIVE CORD behind the unit. Covering as much of the table as possible with the CONDUCTIVE CORD (e.g. by forming a large circle or spreading the CONDUCTIVE CORD out) will improve performance.

4. Do not allow the NEGATIVE ION EMITTER to touch your skin or any other conductive material, as this will temporarily turn the unit off.


Section 7: Cleaning The Units' Exterior

1. Turn unit off.

2. 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.

3. Remove all moisture with a soft, dry cloth.

Note: Always allow the exterior to dry completely before turning your AirTamer back on.


Section 8: Questions & Answers

Q: How does the AirTamer work?

A: The AirTamer uses a carbon fiber brush system to emit healthy negative ions into the air. The emitted negative ions attach themselves to air molecules and any impure particles in the air and negatively charge them. The negatively charged particles, all being the same polarity, repel each other and fly away from your air space and get attracted by the closest positively charged surface (e.g. chair, table, wall, your, clothes, etc.) rather than entering your respiratory system.


Q: What is the units' effective range?

A: Air within a 3 foot range of the unit wilt be effectively cleaned.


Q: What are negative ions? Are they good for you?

A: Negative ions (air molecules with extra electrons) are electrically charged particles in the air that remove airborne contaminates and have been shown to have a rejuvenating effect upon our bodies. The best natural generator of negative ions is lightning, followed by ocean surf, waterfalls, mountains and forests. In clean, natural air, you'll find the highest concentrations of negative ions. In polluted cities and confined spaces, like offices, you'll find the highest concentrations of unhealthier positive ions.


Q: Does the AirTamer produce dangerous levels of ozone?

A: No. AirTamer produces NO measurable amount of ozone.


Q: Can I leave AirTamer® on continuously?

A: Yes. Your AirTamer has no moving parts and uses a very small amount of electricity, so it is very safe and economical to leave on for long periods of time.


Q: Will AirTamer interfere with electronic equipment (e.g. Computers, cell phones)?

A: NO. AirTamer® meets FCC regulations for harmful interference with radio communications so you may use it by your computer, audio players, etc. without causing any unusual interference problems. Pacemaker Patients should not use without first consulting with their physician.
