I personally think this filter is better than Culligan. It arrived with a sealed cap on the inlet and outlet. He sucked air out of the holes when removing the cover. I suspect the airtight lid keeps the charcoal and other chemicals inside fresh. In addition, the coal is cleaned in a few minutes instead of the recommended 10 minutes. The water tastes good and flows faster than the Culligan cartridge. And the best part is that I saved some money.
