New style fitler for Model 3 and 4 Love water distiller. 

If used properly, eliminates overflows and airlocks common to the older style water distillers

Also has more coconut charcoal in it, last longer, and gives a better filtration.

No paper in filter ( unlike older style filters). 

This new design also eliminates water being able to flow around the filter, which could result in

improper filtration.
