Bests & Worsts Reviews from Amazon

I have no complaints about the construction or operation of the filter. It's one of the nicer faucet-mounted filters there are, with a very nice solid feel of quality. However, I did experience what some of the other reviewers mentioned: after a short while the filter didn't appear to have any affect on the taste of the water. The problem, I discovered, is that if you run the water through the filter too quickly (by opening up the tap all the way) the charcoal filter just can't do its job. As a rule of thumb, only allow enough flow through the filter so that it takes about 15 seconds to fill up a glass of water, and you'll have great tasting water. So, if you have high water pressure, make sure you don't open of the faucet all the way when filling a glass. There's just no way a filter as small as this can do its job properly at the max flow rate of most faucets. You really need a large in-line filter for that. Note that this only applies to the filter's odor and taste removal properties, because this involves a chemical reaction of sorts where activated charcoal pulls chlorine (and other chemical) out of the water by binding to them. This is a completely different mechanism than what you normally associate with filtering, such as particles being caught in a mesh (which is essentially how the rest of the filter works in these, and so it's really only the odor and taste that is affected by the rate at which you let water through the Culligan).
