Product review (1 stars): Merchandise Mecca was the worst
Is there anywhere to buy the old filters without the blue wrapping.
I have used Honeywell Humidifiers for many years and never had the smell / mold problem you do with these filters, they are downright unhealthy.
I tried to rate these zero stars they are that bad but the system would not let me.
Please go back to the old filters

December 2015
I purchased four different 504 filters in December 2015 for comparison this one from Merchandise Mecca was the worst experience. Filter was thinnest of the group and it was the only one misrepresented as a Honeywell brand it is Home Revolution brand made to fit Honeywell. This page indicates country of origin is Mexico but filter is from Peoples Republic of China and they went so far as to fold the bottom of the label under so that fact was not readily visible. Will not order from them in the future.

A problem with this and other review pages on Amazon is that multiple products sometimes are lumped together. This page has some reviews about true Honeywell 504s, BestAir filters and who knows how many others. My original review from years ago was about an actual Honeywell filter. Makes the number of stars rather meaningless.
