Can cellulose filter disks be used instead of synthetic filter disks?
    #21987795 - 07/23/15 11:25 PM (8 years, 6 months ago)

I plan on cutting these disks into quarter sized pieces and using then on my jar lids as a gas exchange port.  I noticed, however, that they are not synthetic, and instead are cellulose.  Will they still work like synthetic filter disks, or did I just fuck up and order the wrong ones? :sad:

They'll work fine.

Im sure they would work. But good luck cutting those things into quarter size disks. They are fairly thick. Scissors probably wont do the job, maybe if you had a way to punch them out.

Are they really that difficult to cut?

They're not generally meant to get cut out into small pieces. Lots of vendors and growers say not to cut them because it'll ruin the fibers

Have you actually looked at what they look like before and after cutting under a microscope? It's literally 10 filters pressed together. That's 20-40 fibers. On almost every sponsor page it says don't cut sfds due to messing fibers up.

They've looked under microscopes at it. I'd suggest you try it and tell me your findings. Overall full filter discs are far more effective, and last forever in full.

Never tried. I have a few that came as extras in an online purchase. They are thicker than that pic in your link shows. Think about 3-4 SFD's thick, and much more rigid.

They work great for regular filter disks though. So if you get them and you cant cut them, they arent useless.

yep they work fine, make sure to use foil during the pc run, synthetic's you dont' need too but cellulose you should avoid gettingdamp/wet

Maybe he's saying that because they want to sell more filter disks and don't like people making 9 filters out of one.

If you knew the guy I'm quoting, you wouldn't be saying that lol. Trust me it's accurate. Sfds maybe. Cfds are thick and you don't want hand tools fuckin those fibers.

Once you get those filters you'll understand. They are significantly thicker and more robust than an SFD.

Okay, so is is just not okay to cut them at all, or is just a bit difficult?  Do they need to be used as a single filter placed over the jar lid?

Most jars I've seen on here always have filters that were cut down to size. The fibers may be damaged on the outside of the disc when using scissors, but you're silicone glueing the edge of the disc anyway. The middle of the disc is left unaffected. I don't see why I'd have to use an entire disc per jar, that could get pricey.
