We Use What We Sell.

That means everything that is for sale here on this site.

In fact, the IG-133 series ionizers were originally developed for our own use, with no thought of offering them for sale to help others.

What Has Happened to Ionizing Air Purifiers
Since We Started?

When we first started you could buy other genuine negative ion generators.

But most of them caused a bad "Black Wall" problem, due to improper design.

Of the few Genuine, High-Density Negative Ion Generators that remain available today, they almost without exception suffer from this problem.

Today, it's hard to choose, there are so many out there.

How do you choose between them? Please click here.


Our motto has always been "Take Care of the Customer and the business will take care of itself". And our experience has consistently proven the soundness of this customer-oriented approach (instead of a profit-centered mindset).

We firmly believe in the negative ion generator products that we offer for sale here; in fact, our model IG-series negative ion generators were originally developed by us for our own personal use. (Yes, we still use them. :-)

We now manufacture most of them right here in our own facilities in the Ozark Mountains in Southwest Missouri, USA. And the offices and manufacturing facilities have always been located on the same acreage  that the owners have lived on.


How We Got Started in the Air Purifier Business

Comtech Research first became involved in building negative ion generators as a result of health problems experienced by the inventor's wife. Her allergies and asthma became so severe that he was seriously concerned for her life. All the medicine she regularly took only helped her breathing to a very limited extent. She then tried using an expensive "ionizer" that turned out to be just an ozone generator (a 'thunderstorm in a box') with little or no negative ion output.

The inventor had first heard about negative ion generators when he was in junior high school. So, he started researching the Internet in the 1990's for additional information about negative ions. With his background in electronics (when the other boys were out playing sports, he was in his workshop in his parents' basement building various electronic circuits), he then decided that he could, and must, construct an effective negative ion generator himself.

He then draped the bare electronic circuit of his first negative ionizer over an old wooden wall clock in the living room, where his sick wife was. Two hours after turning it on, his wife was breathing noticeably easier. Was it a coincidence? That was their first reaction; but they had to find out, so the new ionizer was turned off and on (for various time periods). Yes, there was no doubt that his wife was definitely breathing much easier now!

So he built a second ionizer, this time assembling both it and his original unit inside of protective cases.

After several weeks of continued easier breathing, they wondered if other people with breathing problems might be interested in their negative ion generators. Also being in the web page design business at that time, they decided to begin offering them for sale on a web site. The idea was to enjoy helping people and make enough profit to pay the bills.


To their surprise, they also noticed that the sunbeam shining through their east window --through the room and onto the floor-- became almost invisible. Almost NO floating dust was visible in the air any more, only the spot of sunshine on the floor. That is what effective high-density negative ion generators are supposed to do.


An Unexpected Benefit from Negative Oxygen Ions

Three ionizers were finally placed in the living area, bedroom, and office of the old farm house that they then lived in then. One of the ionizers had been placed near the owner's computer desk, for a life test. For months, he had not been able to work at the computer for more than a few minutes at a time. (Why?!) He had tried a new chair, a better computer monitor, a wrist support, even an expensive ergonomic mouse and keyboard, and yet nothing seemed to help.

However, shortly after he put this ionizer near where he was working, he realized that he had spent eight hours at the computer with hardly a break. This was completely unexpected! The negative ions were apparently helping to overcome the bad effect of positive ions being emitted by the big computer monitor. (Scientific research dating back to the 1930s has provided evidence that positive ions can make people tired, irritable, and experience difficulty thinking clearly.) He had heard that negative ions could improve a person's mood, but had not personally experienced anything like it until then. Now this was something: not only might negative ion generators help people physically, but they might even help improve the mood in the work environment too.


In the years since then, Comtech Research LLC has developed improved and new products and now offer additional brands (all carefully selected and tested) to meet the air purification needs of many people.


Note that we are not making any medical claims regarding our ionizers (please see the disclaimer). We are merely sharing our own personal experiences with them.

The Ten Commandments of Good Business (which we strive to meet every single day):

1. A Customer is the most important person in any business.
2. A Customer is not dependent on us - we are dependent on him.
3. A Customer is not an interruption of our work - he is the purpose of it.
4. A Customer does us a favor when he calls - we are not doing him a favor by serving him.
5. A Customer is a part of our business - not an outsider.
6. A Customer is not a cold statistic - he is a flesh-and-blood human being with feelings and emotions like our own.
7. A Customer is not someone to argue or match wits with.
8. A Customer is a person who brings us his wants - it is our job to fill those wants.
9. A Customer is deserving of the most courteous and attentive treatment we can give him.
10. A Customer is the life-blood of this and every other business.

Comtech Research is located in the Ozark Mountains in Rural South Central Missouri.
