The supplied filter I wash after use with soapy water briefly and let them dry, so I'll probably be pretty long do with it.
Before you buy I have made a microdermabrasion at a beautician to see how I can not tolerate this. After the treatment I was fiery red, which was a few hours later back away and leaving behind a delicate and smooth skin texture. I liked that very well, but would in the long run then I have been too expensive.
That was the reason why I had been looking for a home device. I did not expect a great performance because I thought, at this price, the result will certainly not be comparable to that of professional equipment at the beautician.
I was and am still surprised. It can be seen no difference to the professional treatment or to feel.
