Product review (5 stars): Good Quality Replacement Filters, no noticeable difference from prior brands in terms of flow/taste
They seem to fit in just fine as replacements, and I haven't noticed any difference in water flow or taste from the brand I was using before (some other Samsung Aqua Pure line).  One thing is that they don't seem to 'click' into place as the old ones did, so it's not as apparent when they are in completely. However, this is a minor detail, and as long as they continue to work well at this cost, I'm happy to deal with that
