Product review (2 stars): The image shown for this product does not match the item.
The image shown for this product does not match the item.  The image shows this filter to have a blue synthetic interior (I believe this is called an air washing layer). It does not. Previous versions of this filter had this blue synthetic on the exterior.  I have used both the filters with the blue synthetic exterior and the 100% paper filter.  The filter with the blue synthetic withstood handling better when pre or re-soaking. Also, it always lasted longer before the inevitable pink discoloration or hardening from minerals took place. I am extremely disappointed with the misleading image. I would have continued my search for the filter I wanted had the proper image been displayed. Alas, this time around, my nose and skin need my humidifier up and running now, therefore I will use this filter as it is adequate.
