I've had the tops of 2 of these filters blow off within a week.  Fortunately we were home both times and were able to clean up before major water damage.  Had we not been home, we'd be talking insurance and lawyers for water damage to wood trim, drywall, cabinets, and wood floors.  After the first failure, I thought we must have just gotten a bad one.  After the second failure, I cannot trust the construction of this filter and will never buy one agin.  I cannot recommend against this filter strongly enough.
