Great Filter – I Like It!

A'Ville Triathlonβ€”August 25, 2025βœ“ Verified purchase

I picked up the Filterlogic NSF/ANSI 42 & 372 filter as a replacement, and it works perfectly. Installation was simple and quick, and the fit was just right. The water tastes clean and fresh, with no odd aftertaste, and I feel confident knowing it’s certified for safety and quality. For the price, it’s a great value compared to OEM filters. I like it and will definitely buy again when it’s time to replace. Highly recommend! Read more

Good filters for Berkey

ninaβ€”August 27, 2025βœ“ Verified purchase

I have a berkey and these filters have worked great! I am a tiny bit skeptical of how fast the water filters BUT it tastes great and I have freshly filtered water quickly which is great when I realize I forgot to fill it. Read more

Waste of Money

BernBernβ€”December 4, 2025βœ“ Verified purchase

After years of using Berkey's official filters, these were the only ones that were comparable and had good reviews. I am not sure if our family was spoiled, but the terrible quality of our water did not change one bit. The water ran right through the filters to the point that I thought I had installed them wrong. Complete waste of money and on to a new hunt for filters that actually do as they claim. Read more
