Refreshing Negative Ions Help Eliminate pollen, mold spores, dust, pet dander, and many other allergy-causing particulates from the air you breathe, day or night.

Scientific studies about negative ions have shown that some people become moody, tired, depressed, or experience difficulty concentrating either when negative ion counts are low, or when positive ion counts are high.

Negative Ions, Hydroxyls, etc. from our variety of top-quality products help purify and freshen the air you breathe silently, optimally, and safely.

Fresh Air Anytime, Anywhere!

We spend so much time in our cars.  With extremes of hot and cold weather and urban polution we don’t always have the luxury of rolling down the window to freshen up the air in your vehicle.  Check out our automotive air quality solutions.


When it comes to the health and safety of our families more and more consumers are becoming leary of harsh chemicals and solvents.     Check out our alternative air quality and odour control products.

Office windows usually don’t open.  With the extremes of weather, we experience in North America opening a window is not a practical option for fresh air.  What little fresh air gets into the modern workspace is quickly neutralized as it scrubs dust, pollen, and other pollutants.  Couple this with poor air circulation or filtration and you’ve got the perfect cocktail for bad air quality in the office.  Check out our solutions for keeping your office air fresh and healthy.

Antibacterial and Antiviral Applications in Hospitals – Epidemiological Study

Press Release from Leeds University: New weapon to fight hospital infections – January 2, 2003 A potential new weapon in the fight against hospital acquired infections has been discovered by researchers at the University of Leeds. Lead researcher Dr Clive Beggs said: “This is the first epidemiological study of its kind into the use of ionisers in hospital wards and the initial results are very promising. We believe that the negative air ions are removing the bacteria from the air, so stopping the transmission of infection. Our tests have focused solely on acinetobacter, but it’s possible the ionisers may have had an effect on other airborne bacteria. We now need to carry out further research to determine exactly how the ions work and how widespread their effects could be.”

PRESS RELEASE FROM THE LEEDS STUDY

Built to Last

SUPERIOR ION EMITTERS: The part that wears out quickly on other negative ion generators. The one part that wears down on ALL negative ion generators (the ion emitter) is not only replaceable, but long lasting. Standard SSE long-life, plug-in negative ion emitters are reliable, replaceable, inexpensive, and user-renewable. Our optional* long-life CFE ion emitters are made from a high-tech, space-age material that is virtually maintenance-free. The CFE emitter requires no trimming, since the diameter of the fibers is almost microscopically small (only 0.8 microns). And dusting off the emitter is only needed 2 or 3 times a year. The CFE simply plugs into ionizer in place of the standard SSE emitter as shown below.

  • Superior quality, long-lasting, highly effective, reliable, genuine negative room ionizers. Generates an optimum level of high-density negative ions.

  • Very effectively removes particles from the air as small as .01 microns, such as pollen, dust, mold spores, pet dander, and other allergens.

  • Negative ion output 80 to 100 trillion ions per second, externally.(That is, out into your room, instead of being captured and trapped inside the ionizer)

  • For large or small rooms – covers 4000 cubic feet (a 20′ W x 20′ L x 10′ H room).
  • Ionization method requires no filter, so there’s never a need to buy or clean filters.

  • Neither are noisy fans or blowers required. Room air is cleaned and purified noiselessly- completely silent.

  • More effective than expensive HEPA filters or electronic air cleaners: ionized room air does not have to be circulated by a fan and pass through a filter to be cleaned.

  • Uses no chemicals, perfumes, filters, or agents.

Allergies, Pollen & Dust

In the spring, tree pollen is the predominate cause of airborne allergic reactions. In the late summer to early fall, ragweed and other weed pollen is the culprit. Mold spores can bother us through most of the year. Click Here and enter your own ZIP code for the pollen count and four-day pollen forecast for your area. Negative ions help remove allergy-causing particles from the air in your room. They do this by causing allergens such as pollen, mold spores, dust, and pet dander floating in the air (which have either a neutral or a positive charge) to be attracted to and stick to each other, forming ‘clumps’ (because opposite charges attract). These clumps of allergy-causing particulates then become heavy enough so that gravity can simply pull them down to the floor, where they can be vacuumed up, rather than staying in suspension where they can be breathed in and cause allergic reactions. (They do not directly “cure” allergies, hay fever, or sinus problems.)

 

Beat Dust Without Filters

You’ve seen dust and pollen floating in a beam of sunlight shining in the window, haven’t you? Well, when a Comtech Research ionizer is in operation, you see very little (if any) of that. The spot of light is visible on the carpet, but the sunbeam between the window and the carpet is invisible. That is the reason they can help people with allergies: they help remove dust, pollen, mold spores, and other allergens from the air. Negative ionization of the air does a superb job of eliminating most tiny pollen particles that float in the air. They are often normally suspended in the air (even when the air in the room seems calm) just by the normal convective air currents. Because there is no fan (like in filter-type air filters or room air purifiers), the dust on floors and tables is not stirred up, and so the air in a room with a negative ionizer in use can become exceedingly free of dust, pollen, mold spores, and other allergens. And, the air does not have to pass through a filter or fan to be cleaned; the air throughout the room is purified. (Of course, if you have a window open on a windy day and the pollen is blowing in, no negative ionizer will clear the air quickly enough to help anyone.)

Press release from Leeds University Study: New weapon to fight hospital infections – January 2, 2003 A potential new weapon in the fight against hospital acquired infections has been discovered by researchers at the University of Leeds. The scientists studied the effect of negative air ionizers on infections caused by acinetobacter; a pathogen responsible for increasing numbers of sometimes fatal infections amongst hospital patients. Ionizers were placed in the intensive care unit at St James’s University Hospital, which, like similar wards across the UK, has had recurrent problems with infections caused by acinetobacter. For the first six months the researchers, from the aerobiological research group in the University’s school of civil engineering, monitored the normal situation in the unit, taking samples from surfaces, patients and from the air to monitor bacteria levels, and logging the number of patient infections. During the second half of the year-long trial, the ionizers were switched on, and the results were impressive: infections due to acinetobacter reduced dramatically. Lead researcher Dr Clive Beggs said: “This is the first epidemiological study of its kind into the use of ionizers in hospital wards and the initial results are very promising. We believe that the negative air ions are removing the bacteria from the air, so stopping the transmission of infection. Our tests have focused solely on acinetobacter, but it’s possible the ionizers may have had an effect on other airborne bacteria. We now need to carry out further research to determine exactly how the ions work and how widespread their effects could be.” Even without further research, the fact the ionizers are already making a difference is good enough for lead consultant at St James’s intensive care unit, Dr Stephen Dean. “We wanted to be involved in the trial as infections are a major issue for units such as ours, where many patients are already very vulnerable,” he said. “The results have been fantastic – so much so that we asked the University to leave the ionizers with us. Since the trial finished in May, we’ve kept them in operation, and have continued to see greatly reduced acinetobacter infections on the ward.” Dr Kevin Kerr, lead clinical microbiologist on the project, said: Acinetobacter infections are very difficult to treat as the bacterium is resistant to nearly all antibiotics, so prevention of these infections is of key importance. Ionizers may become a powerful weapon in the fight against hospital-acquired infection.

Q:
How Do You Measure the Amount of Negative Ions that your negative ionizers produce?

A:
We test the total negative ion output out of the ion emitter per second (approximately 90 to 100 trillion) using more than one method.

We do different tests of the ion output using several proprietary methods that we have developed in our labs.

Digital readout Air Ion CounterWe use Alpha Labs digital air ion counters. The ion concentration at one meter (39″) away from the emitter is 1,000,000 negative ions per cubic centimeter. These measurements are done in rooms with no fans and roughly 45% humidity. Multiple readings were done at each location and for every model to ensure accuracy.
These tests ensure accuracy beyond what is actually necessary.

We used to not publish these ions per cubic centimeter figures, because they vary greatly with the distance from the emitter, humidity, and air movement within the room.

The bottom line is that our ionizers do indeed emit a high and optimum level of negative ions into a room. The coverage is approximately 400 square feet (e.g. a 20′ by 20′ room). That’s 4000 cubic feet, if you have 10′ high ceilings.

Q:
What can I expect from your negative ionizers if I buy one?

A:

You can expect to breathe freshened, purified air, with much of the pollen, dust, pet dander, and other allergy causing particles removed from the air in your room. And it’s not called the Happy Machine™ for no reason! Many of our customers also report these results.

You can also expect a large number of negative ions to be produced externally, that is, out into the room away from the ionizer (and we include a simple ion detector with each unit to prove it).
What’s so special about that? Some other products with the word “Ion” in their brand name (or product description) produce only negative ions internally, and few, if any, negative ions actually leave the “negative ion generator” and go out into the room. Some actually generate positive ions.

You can expect the negative ions to neutralize positive ions that emanate from your TV or computer monitor.

Q:
“I would like to know if your ionizers make a dark spot on my wall. Mine [another brand] was sitting on the mantel.”

A:
We can count the number of ‘black wall’ (gray wall) complaints on one hand, and have fingers left over, for all the thousands of negative ionizers we’ve ever sold. You were probably burning dirty-burning candles, possibly with a lead wick (which would have sooted up the walls anyway, even with no ionizer present).
It is possible, though, for any high-output negative ion generator to do this, especially if you place the unit too close to the wall and have high levels of pollutants in the air in your room. Burning some kinds of candles can do this, whether or not you have an ionizer.
It sounds as if you live in an environment (or did live in one) that is either very polluted, if you have experienced a dark spot on the wall. We suggest that whatever ionizer you purchase, that you place it as far away from walls and other objects as possible. The mantel, close to the wall, is the wrong place to put any ionizer, ours or anyone else’s. (See “What is the best place to put an ionizer” on this page). The ion emitter design, contrary to some claims you may have seen, has nothing to do with how much dust, etc. accumulates on the wall.
Having said that, our IG-133DG ionizer with built-in DustGrabber™ minimizes or eliminates dust and dirt on nearby objects when the ionizer is too close, and in highly polluted areas such as where someone smokes. The IG-133DG ionizer can also be ordered with mounting brackets for mounting to the wall or ceiling.

Q:
How do your ionizers compare to “Brand X” ionizers?

A:
Please click here to see this information.

Q:
How do your ionizers generate negative ions?
A:
By applying a safe, extremely low-current, negative high voltage to tiny points on the ends of the ion emitter. Electrons then build up on these points, form a corona discharge, and are ejected into the air where they attach themselves to oxygen atoms. Since the electrons have a “negative” charge, the atoms of oxygen with those new extra electrons then become negative ions.

This is the only method possible to generate high-density negative air ions, that is, the high levels necessary to affect most people’s moods.

The voltage level and negative ion emitter design in our ionizers is chosen to optimize the level of negative ions in the room, all without producing unwanted ozone.

Q:
What do negative ions do?

A:
Please click here to see information on negative ions.

Q:
What are the specifications of the ionizers?
A:
We have actually measured over 93 trillion negative ions per second output. And this goes up when something or someone gets close to the ion emitters.

The continuous output measured at a standard distance of one meter (39 inches) from the emitter is 1,000,000 ions per cubic centimeter. This is truly a high-density negative ion concentration.

How we measure this

The actual ion output depends on the air movement, humidity* in the room, and the condition** of the ion emitters, but the average output does not vary a great deal from this. These ionizers do indeed emit a high and optimum level of negative ions into the room.

The coverage is approximately 400 ft2 (400 square feet, a 20′ by 20′ area). That’s 4000 cubic feet, if you have 10′ high ceilings.

These compact units plug into any standard 120 volt AC outlet (other voltages available). Draws very little power (less than 1 watt!), so is exceptionally economical to operate.

The IG-133, IG-133A, and IG-133DG negative ionizers measure only 5 by 5.25 inches by 1.5 inches tall (up to 7 inches tall, including the ion emitter).

* The ion output and coverage of ionizers decrease somewhat at very low humidity. This effect is minimized in the IG-133A and IG-133DG models.

** All ion emitters on negative ion generators deteriorate. However, Comtech Research has developed ion emitters on their negative ion generators which are both long-life, user- renewable, and replaceable! Simply trim the ends of the fine wires on the SSE ion emitter (on top of the unit) occasionally with a pair of wire cutters, according to the instructions, to keep the ion output at its peak.

And our long-life CFE ion emitters are made from a high-tech, space-age material that is virtually maintenance-free. The CFE ion emitter requires no trimming, since the diameter of the fibers is almost microscopically small (only 0.8 microns). And dusting off the emitter is only needed 2 or 3 times a year.

Q:
What is the Best Place to Put an Ionizer?

A:
We suggest placing the ionizers on the front edge of a table, dresser, or nightstand. It should be a couple of feet or more from nearby objects, so that most of the negative ions will go out into the air in the room where you want them rather than being attracted to nearby surfaces.

You should not place your ionizer in places like these: inside a bookshelf, on a mantel directly against a wall, or right next to another object. Why not? Because in those situations, some negative ions will be drawn to the nearby object or surface instead of dispersing throughout the room as they should be.

Many of our customers put one ionizer in their bedroom and another one in their living area. You can place them about anywhere that you would like, with the guideline here in mind. You might experiment, that is, move them around and see which room is best for you. We suggest against putting any electrical appliance in a bathroom.

If you’re only buying one ionizing air purifier, then experts suggest placing it in the bedroom (and we concur). Even though the negative ionizers are rated to cover 400 square feet with high density negative ions, it is really not necessary to get one for each room. However, it would be a good idea to place them where the air naturally is flowing from one room to another (the airflow will help carry the negative ions into the next room). Keep in mind that negative ions cannot travel from one floor to another (nor through walls).

If you have computers, placing an ionizer two or three feet from a computer monitor (to your right or left) will help neutralize the positive ions that emanate from the monitor. NOTE: an LCD monitor, such as used on a laptop/notebook portable computer does not normally produce positive ions.

Q:
What is the difference between the IG-133 and the IG-133A ionizers?

A:
The model IG-133A and IG-133DG have metallic surface(s) on top that improves the performance and ion output of the unit slightly. It is less susceptible to decreases in negative ion output when the room humidity is low, such as indoors in the wintertime (with no humidifier), in an air-conditioned room, or in a desert environment.

If you live in a dry environment (dry in any part of the year), we suggest that you NOT order the IG-133 negative ionizer. However, if you live in a humid environment year-round, you can order the original IG-133 negative ion generator and save a few dollars.

The IG-133DG has the same ionizer circuit that the other two models do, plus an extra circuit inside connected to the two metallic surfaces on top (DustGrabber™). It is recommended for highly polluted environments, and was initially developed because some people didn’t like the dust that settled on the table right next the ionizer. Instead, most of the dust is attracted to those two metallic surfaces.

Q:
How are negative ions different from ozone?

A:
Click here to view the ozone FAQ page.

Q:
Do your products generate ozone or oxides of nitrogen?

A:
All our IG-133 series ionizers and the IG-1215 are genuine negative ion generators, and not ozone generators.
Some “negative ion generators” being sold are really ozone generators, and deliberately generate large quantities of ozone and positive ions (yes, that is true). Ours do not. Neither do our ionizers produce any nitrogen oxides. Ozone FAQ

We do sell some products such as the XJ-3000C, if you need a little ozone in a room ionizer to rid your home of odors.

Q:
Will negative ions hurt my plants or my pets?

A:
No. Negative ions are not toxic or harmful to either people or pets. We once even had a report that a particularly playful kitten chewed on an ion emitter while the ionizer was running, with no harm to the cat.

As for plants, they will likely help the growth of any plants you have nearby.

Q:
Are there any disadvantages to buying the two units combined into one (IG-133DG) versus the two units separately (IG-133A and DC-2 DustGrabber)?

A:
Not really. Operating the IG-133A and the DC-2 DustGrabber™separately emits the same amount of negative ions as the combined IG-133DG unit. If you purchase the IG-133A and DC-2 and operate them side by side, you will notice that the DC-2 DustGrabber collects a little more dust than the IG-133DG combo unit.

The DC-2 is mostly for people who already have a negative ion generator.
