Product review (1 stars): Bait and Switch
The product picture is very misleading.  The filters came in an unmarked package, not the one shown.  The filter boxes only opened on one side (it's difficult to understand how it can filter air if the air can't pass through the filter).  The filter element was paper, not the foam type that was in the original filter (or shown in the picture).

I was able to utilize my existing filter box to put the filter element in for use but I would not recommend these to anyone.
