Product review (5 stars): Fits well and does a nice job, But I still use a little food grade silicone grease for ease of removal.
With so many products on the market that are replacements for the expensive OEM it's a wonder that the OEM's even sell. Based on other reviews I decided on this one based on the ISO seal, and Water Quality Seal which PureLine has several models listed as in compliance. I could not actually tell if this one was one listed but most 3rd party certifiers do not let unauthorized seal use go unaddressed. One thing I do: I keep Food Grade Silicone Grease in the house. I use the grease (very sparingly) on the "O" rings on the refrigerator part and also use a light coating on the outside of this filter and a light coat on the interior were the small "O" rings contact. This is for easier attachment and does make a difference in removal down the road. What would be nice is if these companies offered replacement "O" ring kits since they will wear out and most likely are not standard sized.
