Product review (4 stars): Good alternative to OEM filters, which are now hard to find and twice the price.
I recently discovered that this style filter is now hard to get from Whirlpool or PUR, so I found these and figured for the incredible price I would try them.  These filters are made in China, but seems to be of the same quality and remove the same contaminates as the OEM filters. The filters are an exact fit in the Whirlpool fridge with the exception that the black plastic "handle" which you use to turn it 1/4 when installing the filter fits rather loose.
