Product review (2 stars): Product shipped does NOT contain the blue liner.  Also be sure you flip the filter to prolong useful life.
Note that the filter shipped does NOT contain the blue inner lining.  The version sent to me is all white.  This is the second unit I have ordered, so this is no coincidence.  Though I am not certain how the lining may adversely effect performance, the filter is quite pliable and sags a bit when dampened.

IMPORTANT TIP:  Make sure you flip the filter each time you refill the tanks after unit runs out of water (as indicated in Honeywell's instructions).  Not doing so will accelerate the calcium build-up, and hence, shorten the effective life of the filter.

UPDATE MAY 9 2017:  I have just encountered the 2nd filter that has split by coming unglued. I have forced it into place to function, but the quality of these filters leaves much to be desired.  TWO STARS
