Solution preferences??

The Western Humifier and Western torpedo will only work with distilled water. PG will destroy the foam element. They only need distilled water, because they use a specially engineered element which regulates the humidity.

Climmax media is another product which is engineered to use only distilled water.

The Cigar Oasis product line also only uses just distilled water.

None of the products above are "pre-charged" with a solution and none of them use PG or any derivative of PG.
