Ok, maybe you didn't read my post carefully enough. It's not a filter I'm asking about but an ultrasonic controller.
They plug in and emit an ultrasonic noise, that supposedly disrupt the dustmites, and over a few weeks reduces their population.
I'm sure there are some people on this forum who have bought these devices, and can share their opinions on them.
