    Looks like it's just small pieces of sfd that needs glued to your lid. Idk. I personally wouldn't waste any money on filters as long as tyvek is free at the post office. I have never had an issue using those.

    well, you can buy it, a painters suit at the hardware, just make sure it say "dupont tyvek" on it. Also house wrap is often tyvek and you can dig it out of the dumpster at a construction site. It is white and goes on top of the sheathing and under the siding/brick. Also, I didn't tell you this but you canget it free at any post office in the united states. It is a regular priority mail envelope, make sure it says "dupont tyvek" right on the flap, like so [​IMG]

    at many PO's they are sitting out and you just have one, some offices you have to ask the person for one, but they are still free

    Synthetic filters are the best you can get for your jars but if budget is s problem you could get a painter suit made of tyvek from your local hardware store
    the mail envelopes i would use only if nothing else way available

    the envelopes clearly say they are made of HDPE (high density polyethyline), hence I recommend changing them each time

    I use it for all my LC jars and I have some that have been PCed probably 5-10 times and still work flawlessly.
    Not sure how the HDPE holds up, but it does.
    If its glued on good with RTV and the holes in the lid were deburred properly, the tyvek will most likely outlast the lid!
    Pain in the ass gluing them on. For spawn jars, I just use polyfill(also made of polyethylene).

    if you want to get around gluing small bits of envelopes to the hole in the lid, some people make a disc from envelope, a hole in the metal lid and a spot of rtv on envelope part (shaped like the lid) in same spot as hole on the lids. put the envelope disc over metal lid, trapped over the metal lid with the band. there is enough space between the envelope disc and metal lid for it to breathe through a 1/4" hole in lids below it.
    you inject into the rtv "port in the envelope, it passes through the hole in the lids, and self heals after removing syringe.
    does that make sense?
    really there are a lot of ways to make a lid with FAE port and a separate injection port. better yet, professor p has a good tut on this site.
    i will come back with link if i find it.
    here we go:
    https://mycotek.org/index.php?threads/profs-rtv-injection-port-polyfil-lid-tek.5180/

    i have made some of these myself, as well as the envelope "disc" w/ rtv "injection port" over a lid with a single 1/4" to 5/8" hole direcctly below the rtv. i think PP's tut above works great and should be all you need.
    get rtv and polyfil at a box store for cheap

    *The mail tyvek envelopes work just fine, I use them exclusively under the rings of the jar. The postal tyvek is also water resistant and one layer is sufficient. I wouldn't waste my money on other filters when these are FREE. Yes, I know this is an old post but other people reading this will learn how to get filters from tyvek envelopes.
