Product review (5 stars): Great price for a good replacement for the original Samsung filter
A good, economical replacement for the Samsung original filter.

Documentation and instructions from Samsung are sparse on how to properly change this filter, some advice if you're doing this for the first time to make your life a lot easier and avoid using too much force for the removal or refit of the new filter;

1. Turn off the water supply to the refrigerator
2. Operate the water dispenser to release water pressure - this is important to easily remove the old filter and the replace the new
3. Remove the old filter by twisting - this should happen easily after the pressure is released in 2.
4. Replace the new filter
5. Turn on the water supply
6. Run the water dispenser until you've flushed out about a gallon of water
