Combined 3 units and found them to be too weak to really feel any benefit like improvement in mental state or physical well being or air pollutant and odor remival. Maybe banggood could advise as to how many units are typically required for this product to be effective.

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).

I wired this up and then use a fan to draw air past this unit and then across a grounded metal sheet to attract the dust. Seems to work OK. I will continue to tweek the design to maximize dust collection.

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.

A tiny ionizer that works very well. Small enough to be built in a larger model mains plug, let the HV carbon fiber output wire protrude and you have an excellent little ionizer that can simply plugged in a wall socket where it is needed (near cigarette smoking, tube-type monitor or TV etc) Works really well.

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 !

I don't know how long it can work. It works now. Attached serial neon image with no direct contact.

No se cuanto tiempo puede funcionar. Ahora funciona. Adjunto imagen de neon en serie sin contacto directo.
