How do you choose a good ionizer?

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

Several 'air purifier' products claim to be negative ionizers, but are in fact really ozone generators.

Other "ionizers" only generate negative ions internally. But to be truly effective, negative ions must leave the unit and go out into the air in your room.

And you have to have the right amount of negative ions, produced by a properly designed high-density negative air ionizer.

You've come to the right place.
Comtech Research understands ionizers.

Let us help you choose the right one for you.
