Great filter for a great value
Seems to work great and at a fraction of the cost of the major brand name.

Water Tastes Great!
The taste of our water has improved greatly since utilizing this water filter. We found that we do need to run at least 1-2 gallons of water through the new filter before the water tastes the best to us, but we use those first couple of gallons to water plants, so it's not just running down the drain. This water filter has been a great addition to our house I will definitely purchase this water filter again.

Turn off water before you remove them
I’ve been using these for years now, and when I change both of them out I have extra valves in line so that I can flush the new ones out with out going to each fridge and doing it there especially one of them only makes ice so that hard to flush but there easy to change also we don’t have hard water here

Good filters at a low price
These are really good filters and probably half the price of some of the others. Easy to install, fit tight with no leaks and last a good while.

False Advertising! Complete garbage!
This filter is dangerously misrepresented and has failed prematurely. It is advertised as an equivalent to the Culligan RC 4, yet it does not filter lead, which the RC 4 does. This is a serious case of false advertising. Beyond that, the product's performance is unacceptable. Complete Failure: The filter stopped working after just two months, far short of the advertised 12-month (or even a 6-month) lifespan. I can once again taste bleach in my drinking water. Poor Quality: From day one, the water flow rate was suspiciously high, and the water taste was inferior to even the basic Culligan RC 1. This product's false claims and rapid failure are unacceptable. I am warning others about this and expect a full resolution.

DO NOT BUY As you can see it is missing a critical part. On the original there is a hole beside the inlet and outlet. This is what turns the valve on when you twist it into place. This supposed copy doesn’t have that so it doesn’t work. It also took 2 weeks to arrive and now I have to send it back and order a different brand.

Very satisfied with this filter, easy to install. BONUS: it says 500 gallons in the description, but the product is actually 2000 gallons.

Works well at filtering chlorine taste out of water!

I needed to purchase another Culligan Premium Water Filter for our under counter setup, when I saw the price I started to look for a replacement, found this one on Amazon.ca, read the reviews, then ordered one. It arrived the next day and I installed it. Looks identical to the Culligan filter and it installs easily. After running it for a few days I have to say that I can't tell the difference in the water taste one filter vs the other, so for the much lower cost per unit I'll stick with this new filter "Aqua Crest" . Would definitely recommend this filter ...
