Product review (2 stars): Tastes like tap water and found what can only be carbon ...
Installed new filter, had air in the line for almost 2 days (flushed over a gallon), water would still run after releasing glass from the actuator (never happened before). Tastes like tap water and found what can only be carbon in my CPAP humidifier. Needless to say I've learned my lesson, stick with the factory filter.
