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)

Well built, quality filter. Great value.

Good price, installs with no issues. Just twist off old one (twisting turns off its water) and pull down. then push this up and twist to restore water flow - no need to turn off any other water valve, this does it for you. ie: Yes, can install without turning off water valve anywhere else in house.

Good price and very easy to use. Can't tell the difference between these and my original brand name unit for taste or longevity.

Item: AQUA CREST RC 3 EZ-Change... Seller: Water Purity Expert Tl;Dr: Set correct expectations - this filter makes water taste better, but does not really filter as well as OEM. The item will fit into Culligan filter systems that use the RC-1 and RC-3 filters (and others that the manufacture claims this to be compatible with). Of those two filters, the RC-3 filters better, but costs more and expires quicker... at least when it is made by Culligan. These Aqua Crest filters are a fraction of the price because they simply don't do everything that the OEM filters do. The filtration material is made from coconut shells and does seem to have some ability to remove chlorine since it did improve the taste of water for me, and will probably remove larger particles like sediment. It however does not compare to the OEM and does not do anything to dissolved solids. My municipality provides pretty good water, and water straight from the tap has TDS measuring 37. This filter has no effect on the measurement. This means that if want to use Aqua Crest "filtered" water for any applications where you want to avoid hard water scaling, etc (like for a CPAP machine) or need to remove dangerous substances like lead, use something else. If you just want to improve the taste of your water and the source of your water isn't too bad - this should work. I've used the filters from Aqua Crest for sometime and haven't had any issues with the build quality, but do remember reading about someone who had the glue holding their filter together fail leading to some water damage - something else to consider if you have really high water pressure and want to try using this filter. Also, because of what the filter does (or doesn't do), I'm probably going to get their RC-EZ-1 compatible filter the next time a replacement is needed unless this supposed upper model is cheaper...

High filtration rate at 1/3 cost at big lumber store.
