I'm sorry to say that the model number for the refrigerator that you provided is only a portion of the units actual model number. However from the information I have there are several units with that beginning model number that this water filter fits. In order to find a store that is close to you that sells this filter, press the "Store Pickup: Check Stores" Link on the products front page. That should allow you to fine a store that has the filter in stock that is close to your zip code.

Regrettably, as of right now, Samsung only produces 15" laundry pedestals. However the actual height of the washer/dryer units can be adjusted by the pegs at the bottom of the unit, so this may still fit into your space. I would say measure the unit from the bottom of the actual unit and not from the floor and add the pedestal height. The unit should sit flush on top of the pedestal which would hopefully cut an inch from the entire setup.

The SC-MX20 does have some internal memory (about 50MB) but its really not enough to record anything at length. Using a High Capacity memory card (SD or MMC) will give you much more space to record.

It is not recommended that more then one unit be stacked on any one given pedestal at a time. The pedestals are only rated to carry one appliance at once.
