So I ordered a few packs of the 1 micron filters that we use around the house. To us, the difference between 1 micron and 5 micron filters is CLEARLY visible. Our water and ice is much clearer at 1 micron and is a lot YELLOW in color (especially in a white plastic cup). I didn't rate the taste as it will be another 2-3 months before I test this filter. But some other cheaper filters came and they were NOT individually wrapped. Charcoal was everywhere in the inner bag, 3 "covers" of filters were torn off. It was a bit messy and I don't trust those who actually work. I'm pretty happy with how they look and I'll update my post after I install it in about 3 months!
