Product review (5 stars): best 3rd party filter I've used - as good as or better than manufacturer filters
These filters are great!  I've used other third party filters in the past and have been disappointed.  But these have worked as well or better than the manufacturer filters!  We have well water, so we get a lot of sediment in our water.  But the water that comes out of these filters is crystal clear and tastes great - as well as having the flow rate you would expect.  I had other filters that never reduced output over time (which made me suspect they weren't filtering anything because they should have been getting clogged up over time). These filters filter great, but then do seem to clog up over time (which is what you want, right? - and of course that time will be different depending on your water).  I'm very happy with these and will continue to use them as long as they're available.
