This filter was a breeze to install; granted, the old Kenmore brand filter that this new one replaced was installed with quick-release fittings. While the new filter came with nice brass fittings (with the tread already wrapped in teflon tape!), I decided to use my existing quick-release fittings, which allowed me to swap out the filter in less than a minute. So far, it has been a month, and the water tastes great. The 20,000-gallon life span of this filter was a major factor in my decision. I have well water, and this gives me peace of mind, knowing that my water is getting properly filtered. One thing you may want to do: read the instructions. The manufacturer recommends flushing the filter for a few minutes when you first connect it to the supply line to make sure there is no residual charcoal dust coming out of it. This is normal with most water filters and in spite of having forgotten to do that, I did not experience any problems.
