what is best micron filter bags for rosin press?

When it comes to selecting the best micron filter bags for a rosin press, the choice depends on the material you're pressing and the desired outcome.  Here's a guide to help you decide:

General Recommendations:

25 Micron: Best for pressing hash and kief.  Provides the highest filtration and results in the purest rosin with minimal plant material.

37 Micron: Good for pressing hash, kief, and very fine flower material.  It balances filtration and yield, offering a clean product with decent yield.

73 Micron: Suitable for pressing finely ground flower or trim.  Offers a good balance between filtration and yield, with a cleaner product than larger micron bags.

90 Micron: Ideal for pressing flower.  It allows for a good flow of rosin and maintains a decent level of filtration.

120 Micron: Suitable for pressing flower and trim.  Provides higher yield with slightly less filtration, resulting in more plant material in the rosin.

160 Micron: Best for maximum yield from flower and trim.  Offers less filtration, leading to more plant material in the rosin, but ensures a high return.

Factors to Consider:

Material Type: The type of material you're pressing (flower, trim, hash, or kief) will influence the micron size needed.

Yield vs. Purity: Smaller micron bags provide higher purity but lower yield, while larger micron bags provide higher yield but lower purity.

Pressing Temperature and Pressure: Higher temperatures and pressures can necessitate using finer micron bags to prevent blowouts and ensure quality.

Usage Tips:

Pre-press your material to make it more compact and reduce the chance of blowouts.

Fill the bags about 60-70% to prevent blowouts and ensure even pressing.

Fold the top of the bag before pressing to secure the material inside.

For the highest quality rosin from hash or kief, go with 25 to 37-micron bags.  For flower, 90 to 120 microns are generally best.  If you aim for maximum yield with less concern for purity, 120 to 160 microns can be a good choice.  Always consider the type of material and your desired outcome when selecting your micron filter bags.
