Product review (5 stars): Product has changed and changed again.
Like another reviewer has mentioned, the product has changed.  I've used this product in the past and it came with a secondary mesh filter inside, "clean sense filter".  I had hoped that the other reviewer had gotten a fluke but that doesn't seem to be the case.  After using the filters for the last couple years, i know how long before it needs to be changed so i purchased it anyway.  It came as he described it.  It's missing that color sense mesh filter.  The instructions are actually the same as the old ones.  Those instructions need to be updated since it describes the color sense filters, features, and how it works when in reality, it is no longer there.  The description on the product page needs to be updated as well.  Cost cutting measures for the company?

-2 stars for messing with the product.

EDIT: 2013/05 The product has changed over the years, primary with the style of the indicators (and a time when it didn't have indicators).
As of the current date indicated, it does indeed have the indicator *strips* as pictured for the product, so all is good and I'm changing the rating back to a 5 star.
