More details about the Comtech Research model IG-133DG
Ionizing Air Purifier
Negative Ion Generator and DustGrabber™ combo unit

This model (the IG-133DG), shown below, is a combination of all the features of our IG-133A room ionizer and all the features of our DustGrabber™ in one compact unit. This is what you will get:

Both of the units being operated below are
COMBINED into this combo unit IG-133DG.
(both are available separately)
 
Model IG-133A ionizer (above right)
Model DC-2 DustGrabber (above, left)

• Uses less table space than the two models shown above.
• Only $204.95.
• Includes the long-life CFE-2 negative ion emitter at no extra charge.
• Built-in DustGrabber™
• Completely quiet and very efficient.
• Produces approx. 100 trillion high-density negative ions per second.
• Only 5" wide x 5.25" deep x 8" high
• 5-year warranty and 60-day money-back trial.
• Produces NO ozone, harmful positive ions, or EMF radiation.
• Running 24/7, average electricity cost is only about 4 cents a month.

Designed to last for years.
We still have the first ionizers we ever built, and they still put out the same level of negative ions as they did when they were first built.

Superior negative ion generators.
Our ionizers produce an optimum level of negative ions in your room. We've seen other ionizers that we couldn't even measure the negative ion output from (though we could walk outside and measure the natural level of negative ions outdoors with the same ion detector). Another widely advertised ionizer produced such an extreme level of negative ions that it actually caused a computer in the same room to malfunction.

With Superior replaceable ion emitter.
The one part that wears out on ALL negative ion generators (the ion emitter) is replaceable. The part that wears out quickly on other negative ion generators, rendering it ineffective.

Standard long-life, plug-in negative ion emitters are reliable and replaceable.

All ion emitters are subject to wear. When they are new, a good emitter should have a very sharp point (or edge) as viewed under a microscope. This sharp point is a must to provide the highest efficiency ion output. However, when most ion emitters are examined under a low-power microscope (or high-power magnifier) after a few weeks of operation, they clearly show wear: the sharp point has become rounded and worn-looking.

The long-life CFE ion emitter used in this model is made from a high-tech, space-age material that is virtually maintenance-free. The CFE emitter requires no trimming, since the diameter of the graphite/carbon fibers is almost microscopically small (only 0.8 microns).

The CFE simply plugs into the ionizer as shown.

Orders placed before 2:00 PM CST usually ship the same day.

Comes with a free IDN-1
ion detector per order. 

The features of each section of this model
IG-133DG are listed separately below.

Ionizer section features

DustGrabber™ section features

Combined into this model.
(Ionizer is available separately).

• Top quality, long-lasting room ionizer generates an high and optimum level of negative ions in your living environment, while effectively removing allergens.
  

• Superior air purification than expensive HEPA filters or other types of air purifiers (at any price), using negative ionization of the oxygen in your room.
  

• A genuine negative ionizer, generates an optimum level of high-density negative ions. 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 like some brands).
  

• No filters to replace - ever. Ionization method requires no filter, so there's never a need to buy or clean filters.
  

• More effective than expensive HEPA filters or electronic air cleaners.

• Neither are noisy fans or blowers required, because ionized room air does not have to be circulated by a fan and pass through a filter to be purified.
  

• Cleans and purifies the air noiselessly, effectively removing dust, pollen, mold spores, and other allergy- causing particulates.
  

• No fan, yet emits a breeze of negative air ions you can feel.
  

• Advanced solid-state internal electronics are exceptionally reliable, safe, and produce no harmful EMF radiation. Safe to operate, internally fused, and also feature built-in sealed multiple electronic protection devices.
  

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

• For large or small rooms - covers 4000 cubic feet with high-density negative ions
  (a 20' W x 20' L x 10' H room).
  

• Occupies only a 5" x 5" area on a tabletop or bedroom nightstand.
  

Combined into this model.
(DustGrabber is available separately).

• The DustGrabber greatly enhances the effectiveness of a negative ion generator.
  
• The DustGrabber helps trap airborne allergy-causing particles such as dust, pollen, and mold spores.
  
• It significantly increases the effectiveness of a negative ionizer for air purification and removal of pollen, dust, mold, pet dander, etc. from the air.
  
• Unique type of electrical field near the unit silently attracts more airborne particles of other particulates and allergens without generating undesirable positive ions or harmful EMF radiation.
  
• Helps reduce or eliminate the accumulation of dust and dirt on the table, nearby objects, or surfaces (black wall).
  
• Does not reduce the level of negative ions in the air.
  
• No filters to buy - ever. Just wipe clean occasionally.
  
• Long-lasting, highly effective, reliable, quality designed and built.
  
• Available only from Comtech Research. There's nothing like it.
