Fantastic replacement filter

Benjamin SJune 24, 2025✓ Verified purchase

Great replacement filter for my undersink filtration system. There seems to be a little more loss of pressure vs the OEM filters but nothing too bothersome. Would be nice to see a spot on the labels for writing the date that the filter was replaced, but that's nothing a Sharpie can't fix. Quick and easy replacement of my old filter without any issues.

They work great.

Jeter CreekJuly 12, 2025✓ Verified purchase

We have our own well and must occasionally treat it with bleach. I don't even detect the smell or odor with this on the kitchen faucet. Tastes better than bottled water to me. The water pressure will be down a bit, but worth the trade off. Read more

Works Great, Perfect Fit, Less Expensive

Dean MorrellMarch 17, 2018✓ Verified purchase

This fit my filtrete system with no leaks. It's that time of year here where the rivers start to melt and taste and smell muddy / gamey and extra chlorine is added. Both taste and odor are mitigated by the filter. Since 3M seems to have discontinued my filters I would have had to scrap the under-counter system were it not for this. Works as good or better than the original, less expensive, and extends the life of an intentionally obsoleted system. I love it! Read more

Worth the price.
