Product review (1 stars): NOT Compatable
I purchased these as a replacement for the overly expensive Samsung brand filters.  I had used Home Depot brand filters in the past with good success, but they were out of stock, so I thought these should be a safe bet.  I installed the filter one evening and the next morning  the tray under the filter was half filled with water.  I removed this one and installed the second filter.  Next morning, same results.  Back to Home Depot to purchase the Samsung brand filter, but, before installing I decided to take some measurements.  I measured the outside diameter of the "O" rings with a micrometer and got the following results:
Samsung - 1.100"
Pureline #1 - 1.089"
Pureline #2 - 1.083"
As you can see, the Pureline filter seals were between 11 and 17 thousandths of an inch undersized which explains the leakage.  If I had the time and inclination I possibly could have found some domestic "O" ring replacements that would have provided a satisfactory seal but it was much easier to just return them.  I note from reading the results that some people got good results from these filters but that certainly was not my case.
