DustGrabber alongside negative ionizer


DustGrabber behind negative ion generatorIt must be used near a high-density negative ion generator such as our model IG-133 ionizer for the DustGrabber to be effective in attracting dust, pollen, mold, etc.

We once sent a DustGrabber to someone, and they complained that it wasn't attracting dust. But their ionizer was on a different floor in their house. However, when they brought their ionizer down next to the DustGrabber, "what a difference!", they said. There was stuff on the DustGrabber that he had no idea what it was--stuff he might have breathed in.


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

It really works. There's nothing like it available.
