Product review (5 stars): These white filters work just the same as the old blue ones. Don't believe the few negative reviews.
I was worried about having to switch from the old blue filters to these new white ones after reading some of the negative reviews here. I decided to take a chance on the new filters and not buy a NOS blue filter from another vendor. I have used this filter for the past 6 months and I can't detect any difference in taste from the old blue filter. As evidenced by the top review where they cut apart the two filters, they are the same. Don't believe the negative reviews and feel the need to chase down the old blue filters, these new white ones are fine.
