Tier1 10 Micron 10 Inch x 2.5 Inch | 6-Pack Whole House Carbon Block Water Filter Replacement Cartridge | Compatible with Pentek EPM-10, 155634-43, EP-10, CB-25-1010, Home Water Filter

These filters seem to be just as good as brand name at a better price. Perfect fit and look.

Good safe pacaging

I have tried many different brands. These last longer than the average, yet are cheaper than the average. Have become my standard purchase now.

Exactly what I needed. Fit well, works well. I’m very pleased.

Works as good as the last one I bought.

These are imitation Hydronix and not the worth the money - The inside of the filter was loose, the water tasted of chlorine and there was loose charcoal... I had to return them and ordered the Hydronix so I could drink the water from the filter cartridge. Actually, I was told to not return them and was given a refund. I had to figure out how to dispose of those fake filter cartridges.

Can't beat these carbon block filters for producing quantities of filtered water for drinking and cooking.

Does not fit my Culligan 600A undersink system. Cartridge is slightly too wide.. It appears the Culligan system requires cartridges of 2.375 in. diameter although all these systems are called 10 in x 2.5 in. I have learned the hard way that water filtration is by nominal sizing, like 2x4s. I am disappointed by the poor information provided by this supplier, as I thought these cartridges would fit.
