  • 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.
  • Helps reduce or eliminate the accumulation of dust and dirt on nearby objects or surfaces.
  • 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.

Developed and manufactured in USA by Comtech Research, the Iontronics™ DustGrabber™ has been on the market and tested since 1999.

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.

    “You guys are great!  I have two of your [ion] generators, and after 5 years am just replacing the emitter for one of them.  So happy with your generators :-)”

    “I put the negative ion box in our bedroom and it has been there since. For the past two mornings Jeff and I have woke up with clear heads! No stuffiness! You have my endorsement and it really works! Best wishes and Thanks a lot!”

    “Thank you so much for your understanding and compassion. You have a dedicated company that solves a serious problem. I have had air quality issues for a long time, beginning with my Dad smoking in the house for the first 18 years of my life. Then most recently I worked in a seriously moldy environment. To survive that job, I ordered the personal air purifier from you. Now I work somewhere else, but my personal air purifier is with me, in my purse everywhere I go. I also recommended that a friend purchase one from you. She did and can now handle the negative air quality situation in her work place, much better. Recently, I received a room air purifier from you and had a great nights sleep the first time I used it! I am delighted! My current living arrangements are much healthier now.

    “I feel gratitude that I have no words to express. Also I have enjoyed our brief conversations during the first of which you described your own situation. Knowing you is a blessing. “Your web site readers may experience this as “over-the-top”. I hope not because I have spoken from my heart. When a person can breathe easier, it is life-changing.”

    “I let the unit operate for several weeks with the [SSE] emitter (now in the closet), and then decided to switch over to the [CFE] long-life emitter. The unit continues to do a fabulous job in keeping the air in my office fresh and non-stale. I used to periodically get somewhat low; and sometimes it has been to the extent that I had an unbearable urge to run away and escape from this electronic nightmare –outside to fresh air and a stroll. Now, its actually pleasant to spend time in the office, with this neat and very quiet ionizer.”

    “The 133a [ionizer] is working nicely in the vicinity of my PC with the CFE-2 emitter. Your 133a is my favorite all-time ionizer, having owned 6 different models”.

    “I received the units and plugged them in Friday, one here at work and one at home. Already this weekend I had more energy and got a lot done – much more than usual. I slept more, but still accomplished more in the time I was awake.”
    Mrs. B.D., Overland Park, Kansas

    “I wanted to thank you for the promptness of your order and wanted to wait to write you until I had used the ion machine for about a month to get a good feel for if it made any difference in the way I feel. I can definitely say that I wake up with more energy and in general, just plain feel better!!! In fact, so much better that I would really like to have one of these machines with me all the time–do you carry any models that can be used in the car or a model that is easily transported?”
    Ms. J.A., Lebanon, Tennessee

    “Even in this low-humidity environment, I can definitely notice a change in the quality of air in my apt. I was actually clearing my throat for the first two days the unit was on, as dust and air conditioner “gunk” was cleared by enhanced cilia motion in my throat, besides there being MUCH less fine dust in the air to continue to clog lung tissue in the first place. Yes, the dust is now visible on the unit and I’ve already had to clean it. That’s how bad it is here. I also sleep MUCH better. Good sleep is VERY important to me.”

    “The clip-off wire is a great idea. I’ve been using ionizers for thirty years, and the pins, no matter how clean they’re kept, do wear down. I’ve lost a lot of money to these things.”

    “Dear Sirs, this little unit is very impressive! I can’t say I fully understand it’s physical properties or principles, however I can say it does remove the odors that were causing absolutely unbearable living conditions in my apartment! Including many sleepless nights.
    “I must admit I was very skeptical that this generator could remove the strong second-hand smoke odor created by the smoker living in the apartment below mine, but it did! I placed the Negative Ion Generator in the bedroom (centrally located in the apartment) as high as I could atop my tall dresser. After the first 24 hours there was really no noticeable change… but the second day I noticed a distinct difference, and by the third day – NO odors were distinguishable, NONE! Simply amazing!
    “I’m a severe allergy sufferer, taken allergy-shots for years, had asthma since I was very young, and I’m extremely sensitive to second hand cigarette smoke. The smoke odor in my apartment was not noticeable to some people, others could smell it, but to me – it was absolutely unbearable. I didn’t want to inconvenience my neighbor but feared I would be forced to move… Your product completely cleared the air in my apartment. My apartment is about 1800 sq. ft. and I cannot smell any smoke (nor anything for that matter) anywhere in the entire apartment. I assure you, when I have the money I plan to order another. Thank you for the product and giving me the reassurance that if it didn’t work – I could return it.”

    “Hi, I received the Negative-Ion generator, I was very impressed with the documentation and the ease of the unit, just plug it in, place the pin thing [ion emitter] in the machine etc.. I have noticed that I have not gotten up every morning with my usual sinus pressure since I started using the generator, and that is great!”
    Mr. R.S., California

    “I am POSITIVE that these things work. I am a chemist … I’m sleeping better and have just a general feeling of well-being. Your packaging was marvelous- info about the product, clear concise directions, ion detector. ion emitter. PLUS your website is easy to navigate and very user friendly. Thanks!”
    Ms. J.T, Oklahoma

  17. admin

    “I was skeptical when I ordered the first one, and said ‘we’ll see’. My wife no longer wakes up with sinus headaches in the morning, and I don’t have that hacking cough. They’re doing something. I want to order two more.”
    Mr. O.S., Missouri

    “Well, I have decided then to keep the unit [IG-133A] and recommend you to others. Your prompt and honest replies have been appreciated. I am QUITE relieved to have a neg ion generator again. I feel much better, sleep better and feel mentally sharper. There is NO WAY I would continue to live here in Vegas without one of these.”

    “I recently sent you my damaged negative ion generator and I have received my replacement unit. I would like to thank you for taking care of the problem in such a quick manner. I would also like to complement your company for sending out the replacement unit on the same day of receiving the damaged unit. …
    “Again, I thank you for your impressive support.”

    “Dear Sirs,
    I have already spoken to you on the phone, however, I would like to make a comment that you could post if you like.

    “I recently purchased an ionizer with the dust grabber for my mother who was visiting. Both her and my two older daughters have allergy triggers which were relieved immediately. Upon her return to her house I moved the generator to my bedroom, where even I have noticed a distinct improvement in air quality, even though I have no allergy symptoms. When I initially called to order your product and have it rushed overnight, it was to appease my mom and maybe make her feel better. I was somewhat skeptical and if asked, would have had to waive the ‘B.S. Flag’. But, upon using it in my own bedroom, there are no more mornings with a ‘scratchy’ throat or late night coughing spells in need of a drink of water! You can see the very fine dust particles on the dust grabber as proof of its efficiency. Most people that see it say, What is that?” with a very quizzical expression, and I can’t tell them emphatically enough how effectively it does its job. Long story short-I’m converted, convinced and would recommend it to everyone. Even if you don’t have any immediate discomforts, you will notice an improvement in the air when you didn’t know it needed it!

    “Way to go, Guys! Kudos and keep up the good work and great customer service. (It was very refreshing, not to mention surprising, when you remembered who I was even though it has been a couple of months since my purchase).”

    Thank you.

    “I bought 3 units … I borrowed one to a friend, who has a son with severe asthma, that medication could not correct.
    “The mom spent a lot of time in Doctor’s appointments and emergency room visits, getting prescriptions filled, and putting her son in the shower at night to breath. It affected his ability to even exercise. The child was 10 yrs old, and sometimes quite miserable.
    “She set up a box in the middle of the son’s bedroom with the dust grabber on it.
    “After using the machine for the last 7 months, the mother said that his medication was down to 1/2!!!!!!!!!!!!!!!!
    “Singular and Zertex are gone for the last 3 months. He is still on Buteroil and steroids when he needs it. (mostly around animals). He can exercise much better.
    “She is very impressed and wants to buy the machine from me. Her son happy as can be. The only other thing her son has done is take fish oil, which has some benefit for asthma, but the parents think the machine is the real answer.
    “Thanks for your products. Please abbreviate our names.

    “Again. I want to thank both of you for your extraordinary customer service! I had begun to think there was no such thing as post sale customer service . You must be the one in a million I have heard about but suspected was just another urban legend.”;

    “I first purchased your products over a year ago. They are excellent and unique in the field. I believe that your products are superior in performance to any others I’ve found or used. I think you’ll understand what I mean when I say that your approach is `no-nonsense.` You produce products of the highest efficiency because you will not sacrifice performance for appearance. Your products are certainly not the most `flashy` looking on the market, but as your site reports (and I, myself, have had an opportunity to test) many of the most flashy products don’t really `produce` negative ions. So, thank you for both the your products and your integrity.”
    Mr. Mark G., Hazelwood, Missouri

    “It has only been three days since I received your ionizer/dustgrabber and I am amazed. I have always suffered from severe depression but amazingly I am feeling well, better than I can remember. I have used it in my computer room and find I can work for hours, when I forget it I get exhausted and confused. I now carry it around the house with me from room to room. Also, I have a variety of animals here and I have been endlessly living on allergy pills. Today is the first day that I breathed without them. Thank you from the bottom of my heart.”

    “I received 2 of your Dustgrabber units a few months ago and am happy with them, comments follow.
    -I was appalled to see that my bedroom was the dirtiest in the apartment (being next to the parking lot) every time I wipe it off [the IG-133DG collectors] I see black.
    -Thanks for the basic detector, it helped me determine that my old ionizer/aircleaners don’t compare; the light is on for one but nothing comes out and the other one is weak.
    -Shipping…wow! I estimate it took 26 hours from where you are to Canada westcoast, surprising me at work. Thanks, SS”

    “The two ion machines I got yesterday sure did clean up the air in here! Better than any ionizer I have bought in the past. I have allergies, and I could tell a difference immediately, well, maybe I should say a few hours. The two machines worked even though the square footage you claim they cover is less than the area I actually have. The odor in my apartment is completely gone! And I can breathe better now even without opening a window like I used to. I’m ordering two of your DustGrabbers and a car ionizer. I’d like to resell your ion machines and make a few bucks for myself in the process.”
    Mr. W.H., Texas

    “I’ve used many Ionizers/air cleaners ones that apparently send out very few negative ions which never did anything for me. My doctor recommended yours specifically because of a recommendation of one of his other patients and because he says ones with Ozone are very hazardous.” [ozone comment is only true in high concentrations.]

    “Last year you donated an IG-133A to my classroom. I am writing to once again thank you and let you know of the positive affects of your unit in my classroom. Due to the typical set up of a classroom I was unable (and unwilling) to place the generator in the middle of the room. The only safe space for the unit to be placed was behind my desk. I immediately felt as though I felt better and the air seemed “cleaner” around my desk. While that could have been somewhat of a placebo effect, I can certainly say that much dust collected in the immediate area of the unit. Of much interest is also the fact that my students always wanted to eat lunch sitting around my desk. This could also be attributed to other factors, however, it is unusual and it has never happened before any of my classrooms. I can only imagine the positive effects that a negative ion generator could have in my classroom if it was able to distribute negative ions over a larger area.
    Thank you again.”
