FILTERING HAS ONE PURPOSE
The idea is to clean the crap out, so you will not want to re-use dirty filters, if you are doing things properly.
If you are extracting pills, you dissolve them in the solvent, let the solids settle and filter out the liquid, you. You will rewash the solids let them settle and filter again, you may use the same filter or change it
But you would not use that filter in another step. Personally I would dump the old filter.
In the removal of cut that is moderately water soluble, from product that is highly water soluble, .
You are using the factor that the moderately water soluble cut will remain in the filter, while the product slips through,
If you let it all dissolve, then filter, you gain nothing, So you use minimal sovent, see that the product dissolves , but be certain the cut does not, by rapid filtering.
To use the dirty filter, increases the concentration of cut to product, Continue doing it with a dirty filter and before long, nothing is being removed at all..
A better solution would be to find a solvent, that would not dissolve the cut , but would dissolve the product, at a certain temperature. Often a combination of several solvents will work, since the process is similar to recrystaluizing the cut, then filtering it out of the solvent containing the product.
You would not want to use the same filter you used to remove the Ephed for removing the phos, nor would you use those filters, for removing the pure crystals from the fuel after gassing the product.
In some cases the solid is the trash in other cases the solid is the good shit.
Using one filter is basically insane, or shows a lack of understanding of what the hell is really going on, which is insanity, because of the danger.
If you are happy with the results obtained, then do it,
Most good cooks are always looking to improve the quality, and are concerned secondarily with quantity.
As your skills improve you generally get better quality and a greater yield,
Get stupid and sloppy and you get trash
There are often better ways of doing things, a bit of trial and error, find a better way and post it please.
Point out a specific error someone is doing must mean there ias a better way, so lets hear it.'
I can promise you that using one filter is not the answer,
If you clean pills and expect to yield at the top 10 grams, but you manage to get 15 grams, does it mean you were better at the procedure? No it means you collected more than 5 grams of garbage, or did not bother drying it out.
Confusion, there are a lot of things written, I would like to see the article that says to use the same filter over and over,
It may refer to one specific procedure, re-filtering until the solution is clear , but not to the entire process.
So please produce your source, I sincerely hope this a bonafide question and not an attempt to cloud the issue
Using 4 filters instead of one is really not the greatest idea, but when using coffeee filters instead of lab grade filters, anything that will plug the leaks , is used, Best if filtering out insoubles of small size and using coffee
filters is to insert a cotton or paper plug in the neck of the funnell the tighter you pack it the small sized particles will be caught up., the filtration rate slows .
You would not want to use a rack of fifty coffee filters, it would absorb everything you poured into into it., if you were filtering 5 lbs, 50 filters might work out just fine . if you were working with an ounce. only a fool would use fifty filters.

This is an Oz, that was dissolved in ethanol
, then ignored as long as possible,
after two weeks , I found it again all dried out to this horrific scene
Wanted to murderise the SOB, loaded My SKS .762 Assault rifle, going to make some swiss chease
Note the long crystals at the bottom MSM they are bendable
The only meth
is attached to the sides of the bowl, and it is contaminated with 3 other garbage items,
Don't buy shit from Keith, is what I learned, it is about 15% meth , 95% Crapola, for a tiotal of 110% worthless rip off
