FINALLY, AN END TO THE GREAT 50/50 PG SOLUTION DEBATE?

It all started with an email I received from a reader who asked if PG solution was acceptable for use in an electronic humidifier, like a Cigar Oasis. Since I didn’t know the answer, I went to an expert. In this case, Rob Lembke, VP of Engineering and Process Excellence for XIKAR, Inc. His answer about the use of PG in electronic humidifiers will appear in an upcoming Cigar Advisor Q&A, but here’s what prompted me to address the question of using 50/50 PG in both crystal and oasis foam humidifiers:

In a section of Rob’s reply, he wrote: “…This is the reason we inform consumers that a 50/50 PG solution will eventually clog up a foam or crystal humidifier — the 50% PG stays behind much longer than the 50% water. The PG ratio in your humidifier slowly goes from 50/50 to 75/25 to 100% PG. It’s full of PG that is pulling all of the humidity out of the air! (100% PG will dehumidify to nearly 0% RH).”

Yours truly here has been using both Monster Venom and XIKAR brand PG solution in my crystal humidifiers. So I asked Rob: “Is this wrong? So far, all of the units seem to be responding fine, and several are over a year old. I thought PG only clogged the green foam models. If what you say is true, I may have to walk it back on some of my previous advice. Please clarify and thanks.”
