Product review (5 stars): Easy job, clean water!
I received my order of 6 Culligan water filters today,  quickly and undamaged. Each filter came in a protective cardboard box, and then the 6 boxes all were enclosed in a larger cardboard box. My husband came home from work, I showed him the new filters we had been waiting for and he proceeded to change the filter. First he turned off the water, then unscrewed the filter housing. At that point we already had a bucket underneath the filter housing and dumped the old filter and the debris into the bucket. We rinsed the housing, washed it out, ran bleach through and oiled up the o ring and popped the new Culligan water filter into the housing!  Ready to reassemble the entire project in just under 5 minutes! Tighten up the housing, checked for leaks and DONE!  Great filter, easy to use!~
