Did you spot my enormous boo-boo? In the video I suggested that in 200V+ countries the dropper capacitor could be changed to a 470uF one. I actually meant 470nF and did test it afterwards, with the unit operating as intended, but at half the power.
Assuming you could find a 470uF 400V non polarised capacitor that even remotely fitted in the case, the result of installing it would be brief, loud and hilarious. And result in the instant demise of most of the circuitry. (Which is probably what it deserves anyway.)

I've got a few random ionisers that seem to have been designed by people with no grasp of the science. Even the respectable Mountain Breeze brand experimented with adding pointless gimmicks like variable output control. In reality, the ioniser module could be left powered all the time, as that is how they are intended to be used.

Ionisers put an electrostatic charge into the air that causes fine particulate dust to take on a charge and then precipitate to any adjacent ground referenced surface, including materials you wouldn't really consider as being grounded. They make a huge mess in the process, but have the advantage of being virtually silent and extremely low power.

Unfortunately the quackery surrounding them in the past has given them a bad reputation. But you can prove they work by simply placing one on a sheet of white paper and running it. Within days the paper will be visibly darker where uncovered due to the precipitation of particulates from the air. Most ionisers do produce a very low trace level of ozone that is nowhere near the level present in fresh outdoor air. That trace level poses no health risk and has potential advantages in ambient odour, mould and bacteria control.

This unit has followed the common approach of taking proven technology and adding pointless features as a sales gimmick. From the pointless on/off button to the ramping green LED that dips out and in around every 40 seconds, these features just reduce reliability. The green LED probably means that the unit will be turned off when it should be left active all the time.
