Product review (1 stars): Don't buy this kit.  Buy an aftermarket valve.
Even though this is the OEM water valve for my Honeywell humidifier, it is very poorly designed.  At best the flow that comes out when the valve is opened is barely sufficient to moisten the humidifier pad.  Also, in the tapered inlet end there is a filter which in theory is a great idea.  However, if you have hard water, the filter clogs after about 2 months of moderate use and is almost impossible to remove and clean since it's so small and wedged into the tapered end.  This is the second OEM valve kit I've purchased for my humidifier.  After the second OEM valve kit failed, I bought an aftermarket valve kit at the price of around $35 (versus around $80).  The aftermarket setup has no filter (thank god) and flows more than enough to get the job done.  Save your money and buy an aftermarket valve rather than having to worry about this thing every year when you turn on the heat.
