Extended Cold Maceration ?

The presence of silt indicates the first filter's retention level was woefully inadequate. Hopefully the thicker filter will catch/remove the particulates.

'Woefully inadequate'....sums up My filtering perfectly!!
The visible 'silt' does settle out tho' enabling taking the 'cream' from the top!!

I'm not married to any particular filter, I go with what's inexpensive but still highly effective. These are most recent borosilicate glass filters I bought, they're too small in diameter for folding and using in a funnel but fit my homemade filter holder perfectly Ahlstrom 1610-0550 Borosilicate Glass Microfiber Filter Paper, 1.1 Micron, Medium Flow, Grade 161, 5.5cm Diameter (Box of 100): Science Lab Glass Fiber Filters: Amazon.com: Industrial & Scientific

Those look good. Might have to rethink my funnel size anyways, so I will have to look into the 5.5cm diameter size. Using 15cm funnel and SEOH filters and during three phases, I am losing 20ml or so of extract from the amount the paper filters absorb. By using all three sizes (Slow, Medium, Fast) I believe I am getting a decent finished product. It is taking 1 1/2 to 2 hours for the first (Slow), then another 4 or 5 hours for Medium, then finally 8 to 10 hours to pass through the "Fast" filters. But, as I mentioned, all of these paper filters are absorbing some of the finished extract. The 70/ 80ml I have left are going strait into 120ml brown glass bottles, so they should keep for at least a little while.

Have you tried any of your extracts? Which is your favorite?

Have you tried skipping the first two filters and just use the finest one? Might save a lot of time and reduce absorption losses if it doesn't load/clog up.

Borosilicate glass filters are my favorite, PG will flow through a 1 micron glass filter twice as fast as it would through a 2 micron cellulose filter. Unfortunately, glass filters are usually very expensive. $30 for a hundred ($0.30 each) is difficult to find, normally they run over $1 each. I shop extensively to find bargain prices, when I do I buy them immediately needed or not before the price returns to "normal".

To use a 5.5cm (2.16 inch) diameter filter you'd really need to use a filter holder. You can't buy a real ready-made holder without spending hundreds of dollars (they're vastly overpriced) but you can easily make one from common items. The holder mechanically seals the outer edge of a filter (liquid tight) to a reservoir, when the reservoir is filled the fluid has nowhere to go but through the filter.

I've tried a few. Trout Stream is tasty. Vaping it now with just the 'Slow', or least resistant filter. Great flavor, but gunk's up the coils after four or five ml of vaping. Trying different combination, like Slow then Medium, or Slow then Fast. All three, separately, seems to remove a lot of the flavoring. Although I am hoping that aging might strengthen the flavor a little. I haven't tried just the finest filter, marked 'Fast'. I doubt the 100ml or so would pass through before it clogged completely.

So, extraction complete. Filtration complete. It has been three weeks or longer since I mixed the final product. After triple filtering (slow / medium / fast) these are mixing up fairly clean and of decent flavor between 16% and 20%
But I feel like I am getting a little 'flavor fade' after three to four weeks. Is this normal ?
