Kenmore Reverse Osmosis Drinking Water System —
I spoke with a rep. from Sears Parts direct and the pre and post replacement filters and RO membrane replacement filters are still available. If you go to SearsPartsDirect.com and search on the reverse osmosis model number, the filters show up as discontinued. However, if you search on the replacement filter part numbers, you will find them. The part numbers are as follows:
Pre and Post filters: 3805607
RO Membrane filter: 3857706
In case you're talking to a Sears rep. and they ask, the DIV number is 42 and the PLS number is 625.
Hope this is a help to anyone looking for the replacement filters.
