RC-EZ-4 Premium Water Filtration Replacement Cartridge for Under-Sink, Refrigerator, & RV Systems - EZ Change Water Filter System (500 Gallon Life)

Great water filtration for the kitchen sink, ice maker, etc

Easy on and off replacement filter, good flow, removes bad stuff (metals, chlorine, and bugs), and leaves the good stuff (minerals) that enhanced the flavor of coffee, tea, and drinking water. Lasts six months for a two adult household. Good value.

Starting to use these premium water filters was a game changer. While there are other filters available, I think this is the best. No complaints in this household. Easy to change our every 6 months. Not inexpensive, but cheaper than buying bottled water for drinking and cooking.

The Culligan IC Change with EZ-1 cartridge. The Culligan EZ-x family are very pricy, but they did work very well for us! Frankly, I’m baffled by some of the reviews that stated that it was ineffective because we have nasty well water, and it cured the problem big-time! After trying several of the cheaper brands that failed to do the job, we installed the Culligan IC Change with EZ-1 cartridge, (cheapest,) on the water supply of our refrigerator. This worked great and eliminated ALL the funky odors and taste that made our ice disgusting to drink. Installation is extremely easy, and exchanging the cartridge could not be any easier in that it is merely a quick twist and done installation. To me, this is worth every penny. In short “sometimes” you get what you pay for and in this case, it did an outstanding job for us!

Put one of these in 1.5 years ago or so and everyone loves it. No more bottled water...Can't understand why anyone wouldn't put one of these in and end the hassles of buying bottled water. The thought of Buying water to me was always been mind boggling on a planet that is 3/4 covered in water. The City water where we are is terrible with the chlorine smell, showering in it is really amazing at times it smells like you sprayed diluted bleach in the bathroom. This takes away all orders and almost all chemicals, water taste GREAT. The cities have to treat the water to send it to the people that's just a fact there's no way around treating water for the public, as to what they treat it with can be debated but treating public water is and always will be a must, the cost of not treating isn't an option. So once people realize that treating the water is a necessity then what do you do on your end to turn it back into good water? you invest in one of these and make it simple and make the water GOOD....These are great and work great. Very easy to change also, don't even have to shut the water off the change

I’ve been using this filter for the past couple of years, great tasting water, very easy installation. Family of 3, we replace them every 3 months and about 300 gallons of usage.

I've been using these for maybe 10 years and the water quality is perfect. Highly recommend. I do have city water though so it didn't start out that bad.

I've been using these filters for 4-5 years now, changing them every 3-4 months since I live in an area with a lot of iron in the water and a history of pFOS contamination. I got my first one directly from my local water department, and I've been using them ever since. The water quality from these RC-EZ-4 filters is excellent, and it's really important to me that they remove a lot more than any other type of filter. The quantity of water coming out of the dedicated spigot is pretty good, too. I use it for drinking and cooking and my pets' water. Changing out filters isn't that hard IF you align things correctly. I colored the directional arrows with magic marker so I could see them better to do this. As mentioned, I try to change the filter every 3-4 months (not every 6 months) to keep the water quality up. I'm always surprised at just how heavy a used filter is compared to a new one. It's done its job!

I use it to purify the water in my RV. Easy to install. No shut off needed when removing for the off season. No need to carry separate drinking water. Removes any chlorine and renders the taste neutral.

Provide good quality water and filter lasted over 6 months before replacing

We started with the EZ-3 and it wasn't quite enough filtration for us. The EZ-4 is perfect! We love it and are saving so much money on bottled water!

working good

Initially, I installed the Culligan RC-EZ-1 EZ-Change Level-1 Replacement Cartridge, then this time around for a new cartridge replacement I decided to try the RC-EZ-4-Change Level-4 Replacement Cartridge. I think that the water from this new filter tastes a little bit better than that of the EZ-1 Cartridge. Great overnight delivery, easy to install, and great tasting water! Well done Culligan!
