Product review (2 stars): No Change Indicator Included
From the product description: "Multi-layer with clean sense charcoal and indicator filter set."  However what I received was only one layer as it did not contain the indicator filter.  That's the layer which is colored with blue and yellow stripes.  When the stripes turn to green, that's the indication it's time to change the filter.  Given that this indicator layer was fairly dirty when I've replaced filters in the past, it apparently acts as an effective filtration media as well.  I wouldn't be lowering to two stars just because I don't get to see the pretty colors change. :-)

Interestingly, what I received was a two pack of shrink-wrapped filters with no manufacturer or model# indicated, just a label with a list of all equivalent filter types from various manufacturers.  That was wrapped within another shrink-wrap with a label containing the Broan model number.  Somewhat amusing was that I also received directions (within the outer shrink-wrap) which referred to the indicator layer which wasn't even there.

I noticed that none of the other reviewers mentioned this issue, so it's likely that Broan recently either changed their supplier or changed the specs they gave to their supplier, but forgot to make the corresponding change in their marketing materials.  (Their website still refers to the indicator layer as being icluded in this model.)

Not worth my time to return given the relatively low cost, the fact that they fit and I'll need to replace them again within the next year anyway.  But next time I'll opt for a local purchase where I can see what I'm getting.
