Universal 10 inch Carbon Block Water Filter Cartridge - Replacement CTO Water Purifier Filter, Activated Carbon (NSF 42 Certified) (3)

So far it works well for me, the product is very easy to install.

Had no issues with the filters, the water flavor, or the installation. All the filters were in good condition, and these are a lot cheaper than the ones I normally buy for my unit.

These filter out alot of stuff we don't wish to ingest. After a few weeks they are dark with debris from our city water. We pair these with faucet charcoal filters and we can taste the difference. Not cheap, but better in price than most places.

Best ones I have found so far... tried many others filtering well water and these do seem to eliminate the odor, color and any sediment better than any I've tried. Tried a couple of the string wrapped kind, the cheaper sort of solid ones that are like compressed styrofoam (several brands) and also some 3M Filtrete ones similar to these.The kind of plastic ones are hard to get to seal properly in my filter cannister, the filtrete ones did something weird leaving a lot of green mold in the cannister and other junk. When I used these after the cannister was all stained up and went to replace one somehow the stains in the cannister were gone. I think they also do the job for longer than the others.I also have an under-counter filter on the kitchen sink using a Doulton W9220402 ceramic filter with a separate faucet for it for drinking water.I test my water every Feb. and so far it has been OK as far as safety.

Undersink water purifier system. Our drinking water is now clear & tastes great!

Works just as well as much more expensive models. Extremely easy to install.

I was able to switch my filter with no complications. No flavor at all just clear water I replaced my old one and let this one run for 10mimutes before drinking water.

these are good filters i been using them for a while now in my countertop water filter system they do a real good job!!!!
