We love those filters because they are recyclable, inexpensive, reliable and the filtering agent is biodegradable. We are now at our fifth filter with swift green and not expecting to go anywhere else.
These work as advertised in my KitchenAid refridgerator. Water does not taste funny and nothing is leaking. These filters are much cheaper than the official ones and do the same job.
EDIT: 1 year in I am done with my first 3-pack and getting ready to order another. For the entire year, I never came back home to find my kitchen flooded, and water consistently tasted good and was filtered. I am on municipal water and these work for me.
