I have not previously answered the question about the quality of this item as I wanted to make sure that the problem caused by these items was fully resolved in the first place which unfortunately resulted in ($85 ) call a local specialist and buy NEW FILTERS. I've had the RO for about 9 years now and have changed filters many times myself. When I used these filters the water was yellow and had a very bad smell/taste. The glass on the right was just tap water - the two glasses on the left used my RO with those filters. Unfortunately I had to clean and bleach the system and replace all the filters.
