Customers find the water filter works well, particularly on ice machines, and appreciate its ease of installation, with one mentioning it's a simple twist-on replacement. Customers report no leaks, and one customer notes it's an exact replacement for 3M Filtrete branded filters.

Works great, long life
Uprooted—August 7, 2024✓ Verified purchase
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

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
