    These negative ion generators are much smaller than I thought and obviously produce a few ions but I bought 3 just to use them together and they work well.Moreover,just because of their small size,you can hide everywhere. Thanks Banggood.

    Bij deze kon ik de 3 negatieve ionen modulen in ontvangst nemen , in mijn water verdamper waren ze stuk gegaan , en bij deze snel en goedkoop vervangen , zeer goede beslissing . Al zijn ze maar klein , maar hebben een zeer grote werking !!! verschil met of zonder is wel heel groot merkbaar . zeer tevreden mee gelukkig kan ik ze bij Bang-good.com snel en makkelijk vinden , en voor een verwaarloos bedrag !

    The unit itself is very tiny, but it works fine. The ion wind is easy sensing by your hand. Generate over -3kV voltage (see on my photo below) this is generate a small amount of ozone. Is helpful, because the ozone an oxidizing gas, disinfect to bacteria, and neutralize the odours. (Highly value to poison, but this item a really small amount generated by ozone.) Iam using the room air purifier. In my opinion better a 2-3 little unit per room (instead one big ionizer per room).

    A small-sized device. Power supply 110-230V. Quick shipping. I recommend the salesman.
