Great Filter – I Like It!
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!

Good filters for Berkey
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.

Great filters
These replacement cartridges are very similar to the Berkey brand and a whole lot more economical. So far we are very pleased with them.

Waste of Money
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.

Money Value is Fantastic
Fantastic! Easy to install, now no longer have to buy filtered water so it's safer to use. The durability is great, the water flow is much like turning on the tap to get chemical free great tasting water. Well worth the money.
