Would you care to elaborate on that? "lite filters"... ? More research? ...?

Response is not recommended....something is a bit off, not sure what, but let's hope some are not litigious by nature.

Default Bactericidal effect of propylene glycol

Hi,
First post and wanted to share this independent research which concurs with the NZ testing in which they had two groups of hospitalized adolescents, one in "normal air" as control for the second group which breathed vaporized propylene glycol. The propylene glycol group had measurably fewer infections particularly of the respiratory types than the subjects in the control ("normal air") group.
Hope this helps the cause.

Lar

p.s., I am still deciding on my first PV- but I'll get there!

Studies conducted in 1942 by Dr. Oswald Hope RobertsonBillings Hospital showed vaporized propylene glycol inhalation in laboratory mice may prevent pneumonia, influenza, and other
respiratory diseases. Additional studies in monkeys and other animals were undertaken to determine longterm effects, especially the potential for accumulation in the lungs. After a few months of treatment, no illeffects were discovered

Hi harvest - I found the same article on wikipedia. I wonder why no studies like this have been repeated in the last 60+ years? Or at least none that I can find!

This is really the first potentially scary thing I've read about propylene glycol. It pertains to ingestion, though, not inhalation, and it's pretty vague. But since it's a report from a state government, I thought it was worth posting.

I can't post links yet, so just add the h t t p : / / to this:

des.nh.gov/organization/commissioner/pip/factsheets/ard/documents/ard-ehp-12.pdf

Excerpt from near the bottom of page 2:
Quote:
Rats exposed orally to a high concentration of ethylene glycol had blood effects such as reduced red blood cells and hemoglobin, the protein that carries oxygen. High levels of propylene glycol caused similar effects in dogs. In another study, high concentrations of propylene glycol fed to rats resulted in changes in their blood indicating that red blood cells were being destroyed.
After all the reading I've done about propylene glycol, my personal feeling is that it's relatively harmless, at least for short term use, as a direct inhalant. My own real concern is whether it could pose health hazards long term.

I don't think it is a good one. It is better to have a through knowledge before making to any solutions.

For information on PG you can visit the National Library of Medicine website:

HSDB Search Results - Frameset

Make sure you read all the way to the bottom. The final entry reads:

Minimum Fatal Dose Level:
1=PRACTICALLY NONTOXIC: PROBABLE ORAL LETHAL DOSE (HUMAN) IS ABOVE 15 G/KG; FOR 70 KG PERSON (150 LB), MORE THAN 1 QT (2.2 LB).
[Gosselin, R.E., H.C. Hodge, R.P. Smith, and M.N. Gleason. Clinical Toxicology of Commercial Products. 4th ed. Baltimore: Williams and Wilkins, 1976., p. II-120] **PEER REVIEWED**
