More Information

This Demineralization Cartridge is a replacement for the older part number: DC-51-6. It is exactly the same cartridge, and is intended for use with Vicks Ultrasonic Humidifier Models: V5100 and V5100N.

The Demineralization Cartridge is placed in the bottom of the humidifier and helps to filter the water and remove large particles and minerals so that they are not misted into the air with the water.

functions as advertised, but only lasted two weeks.

Protec DC-51 

It took so long for the filter to arrive that I've only used it once.  The humidity in my area has increased to a tolerable level but how long it will stay that way is unknowable.  The one use I have had indicates that it does cut way, way down on the white dust but I don't know if it will last the indicated 3 months.  I suppose that will depend on how hard my water is.  One thing I did not like about it is that the 15 min you ar to wait for the water to filter threw is really more like 30 min. At this point I like it.
