Since I installed the filter, there are now 1 month, more tightness, and inevitably I find gradually a significant improvement in the condition of my skin. To be continued. But for now yes, the filter is effective!
Now see if the filter held throughout the year at least, according to the product file.
* EDIT 8/19/2013: But that's only one month that the filter was installed and what I feared was confirmed today My skin begins to take after a shower, a sign that the filter is no longer effective. I opened the case and returned the cartridge as explained for maintenance, it makes no difference.
Also according to the wear indicator on the filter cartridge, if the color changes to black it means changing the cartridge, and the indicator is actually black.
I ordered a new cartridge 47 with shipping to ensure that the first was not defective. I will monitor how long it will remain effective.
If it turns out that the average is 1 month, in my case, I'll have to think about an alternative solution for the total cost of this facility would prove too much then if I have to replace all filter the months!
