Negative Positive
Title: crystal clear air
Review: This Wein unit emits pulsed discharges from a wire brush; a unique method of generating negative ions. The emitter is not replaceable, but Wein claims does not wear over time. This is a very powerful industrial strength generator, which does make a slight hissing sound. My ion detector registers a high level of negative ions even some distance away from the emitter. The coverage area is 800 sq ft, so I recommend this unit for work if you are in an open area, or heavily polluted areas, such as your garage. Since it is so powerful, there is potential for increased blackwall effect.I believe this is one of the more powerful Ionizers available on the market today.
Is the review positive or negative?
