Product review (4 stars): Long time user
Pro's:  Good at removing chlorine, according to my pool test kit (and taste). Easy to change if you have an inline shut-off valve. Con's: Cuts  flow rate by about half (on my 65 psi system), which makes filling a 12 oz glass of water at the fridge  a 20 second affair.  Not tolerant of rust or sediment, which quickly clog the filter and reduce flow to a trickle.  Amazon bests Home Depot by about $8 on this filter.
