I personally would recommend those filters. It's a greater micron size, but it's already much less than that of you 72-25μm filter for a dry sift press. Speaking of which, there's a few tips I will give based off the best results I've seen so far
-If you are able to, use a 150μm, full-spectrum dry sift thats pressed through a 25μm and run more pressure at a lower temperature, with more time and cool them on something cold. This allows for the taste of full spectrum without the need to reintroduce strain profile terpenes.
-Learn to make rosin jam. This is more of a syrup consistent and will allow for easier separation of lipids through the filter and will be closer to a distillate consistency requiring fewer terps.
-Only use enough to emulsify when heated in a magnetic stirrer hot plate.
-Use a magnetic stirrer hot plate
-Use a simple green crystal clear concentrate diluted in distilled or boiled water on warm temperatures immediately after done with use in an ultrasonic cleaner. This will clean, degrease, and be medically sterile when it comes out.
-When using the filter, you want the liquid to be slightly luke warm, this not only speeds up the process, but it also basically sperates more materials like lipids that will separate if not mixed together correctly.
-Get the German made Truth brand, 10ml Borosilicate syringe with a lier lock. That's what the syringe filters lock into. You also get finer graduations with 10ml as opposed to 20ml. You can even hook a PID up to a email coil and fit it around the syringe body and set the temp to 150 just to keep it warm enough to stay liquid but still cool enough to get better filtration.
