Waterdrop RC 3 EZ-Change Premium Under Sink Water Filter, Replacement for all Culligan EZ Change Water Filter Systems, Including RC-EZ-3, IC-EZ-3, US-EZ-3, RV-EZ-3, RC-EZ-1, 500 Gallons (Pack of 2)

So far so good! I’m happy with the water flow, and taste is excellent!

I have been using this filter for five years . It improves the taste of one water. They are easy to install and have had no problems.

Excellent filter, perfect fit, easy to replace. I buy a pair of these and replace mine and my mother-in-law's at the same time once per year. I have used this model every year for the past 3 years and it meets my needs.

For me,these filters are a direct replacement for my Dupont water filter system with a price advantage. Seams like they filter our water good. Very easy to change.

These for my Culligan under sink filter, and remove the whiff of chlorine I notice from our tap water. The filtered water tastes great, and my ice maker seems to like it as well. The price is amazing. You get a two pack for less than one name brand RC-3 filter. But…is it actually filtering the same way a Culligan RC-3 does? I have my doubts based on my observations. The RC-3 filter provides a higher level of filtration and as a result the flow is noticeably slower than an RC-1 filter. These flow as fast as the RC-1 filter they are replacing. They are also rated for more gallons than the RC-1 filter, which is rated for about twice the gallons of an RC-3. Can I prove my suspicions? Well, if I invest in some tools maybe. But it doesn’t seem to behave the same way as an official filter of the same rating. Am I returning them? No, because the basic filtration is what I need in this town, unlike my last place where we had some recurring water issues. Even if these are filtering at the same level of an RC-1 filter (chlorine and odors), I get two for the price of one. And when I’m done with this first one, I will cut it open and see what’s what inside.
