Product review (5 stars): Crystal Clear Water
These filters cannot be beat for the price.  As with any charcoal filter, you have to run some water trough it until it clears.  This is common with charcoal filtration and not a defect.  Also when a new filter is installed it is not uncommon for air to enter the system so expect some sputtering at first as air is worked out of the system.  Once you get passed these two points you will experience crystal clear, clean water with no chemical taste whatsoever.
