Product review (4 stars): These are the best ones yet
I purchased these since you cannot get the original filters any longer. I have tried a couple different ones and decided to try these because they were the only filters that actually said were tested to  NFS certified specs. These are the best ones yet, hardly any carbon specks when flushed as directed. Some might think the water flow is low but they flow the same as the originals (discontinued) and the HDX filters (discontinued) I used in the past. I am pleased and will use these until they are discontinued or get a new fridge. Thanks,
