Since I have a whole bunch running and IMO I don't think the demcifliters are doing a great job keeping the fans clean.
I was wondering if anyone had a supply for thin cheap filter material I could use under the Demci filters.

If your case has good dust filters then your fans shouldn't be getting dusty. A good vacuum cleaning from time to time is about all you can do really.

Better than conventional mesh computer filters but I would like something better, to combine with the mesh.
I was moving some gpu's around and noticed the slight buildup and wanted to prevent bearing failure..or postpone it.
Vacuuming them would increase the risk of damaging them and really isn't stopping the dust from getting to the bearings.

I have no idea if this is thin enough for your needs:
 
Amazon.com: Pura PC Computer Air Filter - Polyurethane Foam Filter : Electronics

I was looking at that and another option is

60 ppi

I would like to test some out and see if I can put it directly under the ones I have. Now that have said it maybe it should be taped on the outsìde of what I already use..Not sure!

Just make sure whatever you use doesn't kill airflow. No, I haven't figured out how to turn my PC into a room air filter. Maybe, a whole room air filter may work better in concert with your Demi filters.... Mine are definitely dust magnets.  

STR1D3R_2 I was thinking that too then I saw the price of room air purifiers...
With the cost of them and the extra electricity I thought... make use of the computers own  air movement.
I have closed all the windows in the basement..that should help (each was open a couple of inches)
I have a fan pushing air directly into the return air and I have two large fans at opposite ends of the basement pushing all air towards the return.
I have a little static clingy duster that I could try and clean up the blades...
It isn't allot of dust just the fine stuff that gets by the Demciflex filters..
I have an old furnace motor and squirrel cage that I guess I could adapt but I would need to reduce it's speed...it is a whole house blower off a really old furnace.
Off Topic..

I have gone the extra miles needed to keep it safe...literally walking them ...to keep it from getting door dings etc

Can't get my head wrapped around WHY!

I'm smart enough to afford a whole room of PCs.   if that makes any difference.  
 

Same here. My cats, dog, kids and wife are off limits. I have to walk through a secret door behind the shower to get in and then put on my eye protection for the UV lights. It's a drag when I miss a bid on flee bay. but at least my fans are clean lmao

Iza joke Joe. UV = ultra violet as in decontamination entry into the man cave.

Rookie.  Wheres the trap door?   But do you have a camera and a motion sensor?  True story

I suggest investing in a good old datavac

Take the machine outside, blow the dusty bits outside, bring back in. Or, in general, just get a room air purifier. It will cut down on dusting of the other furniture in the room as well.

Forgot to mention, that is how the shower is accessed.

In my mind...dangerous place...
I am thinking if the filter material is conventional filter material and close to the fans it will put more of a strain on the bearings making them pull harder and wear out faster...
The fans aren't designed for that type of operation 24/7
( I have sent one of my gpu's in for just this problem and it was up very close to the wall of the case. There were slots in the case but there was also solid steel blocking some of the fan. So that could have been my fault. This was my first mining case and had been running the longest, I relocated the gpu's in the other enclosure and they appeared to be working fine)
I am going to focus on the room size filter to start with...
If you look at the landscaping fabric it is actually quite porous and I won't be attaching it under the Demciflex filters but more over top hanging down like the side of a table cloth.
Thanks for the info Jim
Next time I am down at Lowe's, we have them up here, I will check it out.
 

try aliexpress, you will be surprise what you can find to turn your pc into

Maybe you should just buy an air filter 😂
