Product review (5 stars): Green Filter for LG 5231JA2006B,5231JA2006A,5231JA2006F replacement water filter by Swift Green Filters
I replaced my LG JA2006B with this filter because of the price point.
The Green Filter is smaller in diameter than the LG but I don't believe that has any bearing on its effectiveness as a filter.
I can't do a chemical analysis on the filter manufacturer's claims so I can only trust what they ( LG and Swift Green Filter) say.
From my viewpoint, I cannot tell a difference in the taste of the water using the Swift Green Filter therefore I will continue to use these Green Filters as long as they are priced attractively.
