raw-filter-material
    #779766 - 07/27/02 09:34 AM (18 years, 7 months ago)

What's best raw-filter-material for covering jars or to build in spawn-bags.

Hepa, Ulpa , P3 , ... ?


Hepa and Ulpa are the best material but they have a big air-resistance
so it's possible that no air-exchange happens.

And which filter material fits for sterilisation.
I think - but I don't know exact - the filters are build of diverse materials
and I want to know which materials are fit for sterilisation and which are not.

Last I made an experiment with simple wadding of an aqaurium-shop and it smelled a little bit by sterilisation .
I have no fun on taking best ecological nutrients for growning mushrooms and let them contanimate with toxic vapors .

Sorry, wish I could help but I am kinda conused by your wording of the question, I am not sure what you are asking. I know that poly fill that's used for pillows and stuff works really well in avoiding contams and allowing air exchange, maybe that helps.

I use Tyvek. HEPA & co. are too expensive for this kind of use.

I'd go with pollyfill as well. It's really cheap and you never run out. You can get it in the arts and crafts section of Wal-Mart.

Thanks for your postings !


What kind of material is polyfill. It's like wadding for cosmetic or is this an other material.
I heard there are many sorts of wadding.

Examples:

- waddings uses in cosmetic - I think it's made of cotton or viscose

- wadding uses to filter water by aquariums and mades of an synthetic material


I heard in another forum that the cosmtic wadding is hydophil and stores the water so the wadding is wet after sterilisation.
And the other wadding ( mades of synthetic ) shall be better because it's hydrophob and better for using as filter because it don't stores the water.

Is it's true or not ?

I tried the synthetic one but it smells a little bit by sterilisation so I think it's not the real think to use.

What kind of wadding do you use - or is polyfil not a wadding - hmm

Sorry of my bad english - I will rectify - I promise

And what are the exact ingredients of it. I think in my area the products has other names so I've to look on the ingredients .



In my research on the Tyvek-sides I found a lot of product they offers.
What of these products are the bests.
I saw one product - calls

"Tyvek 1431N".

The technical description sounds very great but I read that one side of the material is handled for having antistatic properties - made chemical or physical I don't know.
Is this extra handling of this material a problem in sterilisation by making toxical vapors ?


Thanks for helping
and have a good time



Vladi
