Works great, long life
These are more economical than most, and I find no difference in taste or water quality. I use them for a full six months before changing. They are easy to change, with clear instructions, and stickers to place on side to remind me when to change again. I have purchased this brand several times, and am very happy with them. Thank you for a great, inexpensive product! Read more
Easy installation
When I flushed the filter the water came out black and subsequently cleared. This was the first time I have ever seen this is with water filters. It makes me wonder what invisible contaminants are in the water now. Read more
