Would this tyvek be good for a filter patch?

I don't see why it wouldn't be.You could use poly-fil if you like too.

Usually people use tyvek sleeves or suits to cut up. Not sure if that shit can breathe, as its purpose is to block air. Maybe someone knows for certain.

You sort of answered your own question.

Would this tyvek work? = Would tyvek work?

If it's tyvek, it works.

This isn't tyvek, its tyvek tape. I've only used micropore tape. Tyvek  to me has always had to be RTV'd  on.

Its purpose is actually to NOT block air. It's a permeable membrane and that's what makes it cool. If tyvek didn't breathe it couldn't be a filter.

I was referring to the tape in the link, not tyvek in general. The link specifically states that what its for, which is why I'm suspect of it.

:facepalm: I didn't realize it was tape. Anyways, I definitely don't suggest it. You'll probably wind up with substrate or a dry verm layer sticking to it and it's full of other chemicals and won't breathe as previously mentioned. Sorry for the misinformation! Teknix is right to question it.

A little more info on tyvek tape is on this site: http://www.loyola.com/icf/products/vapor-barriers/tyvek-tape.html

Thanks MycologicalMind. It seems that tape is for tyvek to tyvek adhesion, not made out of tyvek material! I also ordered some free tyvek envelopes via your link! Do you think I can also pick them up for free at the post office? I just went to the UPS store, and they didn't have any. They had some free ones made out of plastic material and some out of cardboard, but I don't think those are the right ones.

One thing you have to bear in mind is that Tyvek is a brand with many different products.  I dug through their documentation and there's no data regarding well how tyvek home building materials works a microbial barrier. 

However, there's plenty of documentation regarding tyvek protective gear such as suits and sleeves.


DuPont TY127S Disposable Elastic Wrist, Ankle & Hood White Tyvek Coverall Suit

This suit uses standard Tyvek brand Tyvek and has a Log Value Reduction of 5.2

Quote:

Log Reduction Value
A Measurement of Retention Efficiency

There are three common measurements of retention efficiency, Percent Efficiency, Beta Ratio and Log Reduction Value (LRV). This session of One Minute Filtration will focus on Log Reduction Value.

Log Reduction Value is a ration of the log to the base 10 of the challenge concentration divided by the filtrate concentration. It is most often used when there is a high concentration of a single challenge material, such as bacteria or latex beads. In the Pharmaceutical Industry the definition of a Sterilizing Grade Filter is one in which has a LRV of 7 and a sterile filtrate when challenged in accordance with the HIMA (Health Industry Manufacturing Association) test protocol.

LRV = Log10 Challenge/Filtrate

In the case of the Sterilizing Grade Filter, it is challenged with 107 bacteria of a prescribed type (Brevundimonas diminuta ATCC19146) per square centimeter and there is zero in the filtrate. Since it is not appropriate to divide by zero (0), a 1 is substituted and the terminology of β€œsterile filtrate” is added.

LRV = Log10107/1 = Log10107 = >7/cm2 and a sterile filtrate

Another example commonly used for measuring the efficiency of filters in the Microelectronics industry is a challenge of a particular size latex bead. In this case a filter might be challenged with 106 0.05 Β΅m latex beads with 102 in the filtrate. In this case the LRV would be 4 per filter.

LRV = Log10106/102 = Log10104 = 4/Filter




I'm not saying it doesn't work, but there's no data one way or the other.  If you're up  it make a batch of lids using it and PC it then let them sit out and see if/when they contaminate and post the results.

I've been using an off brand of tyvek with good results, I did check their specifications before using though (home depot sells this brand).



Trichoderma spores are typically 3-5 x 2-4 microns in size as a reference point.

Shit, I didn't click his first link.  That's tape used for sealing seams in Tyvek home wrap.  You need the home wrap itself.

If you try to by the actual home wrap at Home Depot, you'll have to buy the entire roll, NOT CHEAP.

Go to a construction site while they are in the siding phase.  They'll probably have scrap laying around that they'll give you for nothing.

There is tyvek all over ebay, like 1X9 ft for $1.75.
However many feet X 9 ft you want.
Meaning 2X9, 3X9, 5X9, 10X9.... whatever.
