Tyvek vs. Coffee filters
    #3750188 - 02/08/05 10:19 AM (12 years, 3 months ago)

when using quart jars and grain can coffee filters replace tyvek?

"I like cigarettes, Miss Taggart. I like to think of fire held in a man's hand. Fire, a dangerous force, tamed at his fingertips. I often wonder about the hours when a man sits alone, watching the smoke of a cigarette, thinking. I wonder what great things have come alive from such hours. When a man thinks, there is a spot of fire alive in his mind---and it is proper that he should have the burning point of a cigarette as his one expression."

I find the nice thing about tyvek is that it is water resistant, but lets air pass through. Water is a great carries for spores and bacteria.

NO. Coffee filters are to porious, fragile & contaminates can pass through them.

Ughhhhhh..... you have it backwards. Moisture (vapor)& a very small amount of gas can pass through tyvek. Tyvek is resistant to the passage of air. Hold a piece to your mouth & try to blow through it. Nada.

Quote from Tyvek site: "The unique qualities of Tyvek? help stop air flow through wall cavities; help hold out bulk water and wind-driven rain; and allow moisture vapor to escape from inside walls.".

Okay ... You have zero construction exp.
Tyvek was first developed to be a moisture barrier for homes in humid climates where molds and such are a problem. It was designed to keep moisture out , yet allows for some breathing thru the back , so that IF some moisture does get in behind it it will evaporate and pass thru the material itself.I wonder how many of you tyvek users even use it correctly , as far as which side should face out  :confused:The water resistant side is the side with the wording, the opposing side is the breathable side .

I hope this helped you explain the proper use of tyvek agar, we do not want you blowing a vessel helping those who have no clue :wink:

I think what chocbruce meant was it resists being wettened (unlike coffee filters which sop up water), while allowing for gas to pass through it. It would be more handy for us if water vapor wouldnt leave it but gases would. Before people go telling me why that cant be done, I just said it WOULD be handy :smile:.
