Any material, any plate size, and guaranteed to reduce blowouts!

PurePressure's new and improved rosin filter bags are stronger than ever, food grade, and are made in Denver, Colorado. These premium rosin filter bags are manufactured from ultra-durable nylon monofilament mesh and hand stitched with premium polyester thread.

All raw materials are FDA approved for food contact and have undergone thorough testing; see our declaration of compliance below for more information. These bags are made to the highest quality control standards and come with a peace of mind replacement warranty.

Available in every micron type, bag size, and pack quantity that you could need, the hunt for the ultimate rosin filter bag has finally come to an end. Oh, and did we mention they ship free to United States as well? We're confident you will not find a higher quality bag at a lower price.


  • Made with ultra-durable FDA food grade nylon monofilament mesh combined with FDA food grade polyester thread
  • Designed to maximize yields by minimizing the distance the oil must travel
  • Nylon offers mild stretching properties to reduce blowouts and ensure excellent reliability
  • Proprietary stitching pattern for unparalleled seam strength
  • Each bag is intended for single use only

Rosin Filter Bag Guideline

Ice water hash and sift

  • 36 Micron: very fine filtration, #1 seller
  • 72 Micron: medium filtration, mainly for sift rosin, with the potential for yield increase

Flower rosin

  • 90 Micron: more filtration, offers higher quality at the expense of some yield
  • 115 Micron: best yield, overall top choice for flower rosin pressing

All of PurePressure's premium rosin bags are designed to be turned inside out for maximum strength and seam integrity. Simply turn it inside out, fill it up, fold over the end and you are ready to press. They are intentionally made to be an extra half inch longer to allow an extra half inch for folding.


2" x 3" = 1.8" x 3.5" inside out
2" x 6" = 1.8" x 6.5" inside out
2" x 9" = 1.8" x 9.5" inside out
2.5" x 9" = 2.5” x 9.5" inside out

Product Q&A

PurePressure 2" x 6" Rosin Filter Bag - 115u, 90u, 72u, 36u Questions & Answers

Which Material Should I Use?

Yields range significantly and depend largely on the quality of the materials used.

  • Trim: 3% - 8%
  • Shake: 8% - 15%
  • Flower: 15% - 30%
  • Dry Sift: 30% - 60%+
  • Ice Water Extractions: 30% - 70%+

Note: Adequate application of pressure is important to achieve optimal yields and these figures are based on averages tests. Results may vary and depend heavily on your material as well as the operator.

Which Micron Bag To Use?

Depending on your material, the proper micron bags are suggested but results will always vary.

For dry sift and ice water extractions use a 36 micron or 72-micron bag. 72-micron rosin bags will offer higher yields compared to 36-micron rosin bags, but the 36-micron bags will provide the highest quality product.

For flower, trim, and shake, use a 115 micron or 90-micron bag. You will get the highest yield from a 115-micron rosin bag compared with a 90-micron rosin bag, but the 90-micron bags will give you more filtration and slightly higher quality product.

  • 36 micron - Most filtration available, highest quality output rosin for use with small and finer material.
  • 72 micron - High level of filtration, increased yields over 36 micron when pressing smaller and finer material.
  • 90 micron - Higher level of filtration for use with flower, trim, and shake rosin pressing.
  • 115 micron - Ideal level of filtration and high yielding for use with flower, trim, and shake rosin pressing.

What Temperature Is Ideal?

  • Lower temperatures (200°F- 300°F) = more flavor/terpenes, less yield, end material is more stable (shatter-like consistency).
  • Higher temperatures (300°F- 350°F) = less flavor/terpenes, more yield, end material is less stable (sap-like consistency).

How Much Pressure Should I Use?

There is no magic number for how much you need to press but most people use the formula of press pounds/plate surface area.

For example: A 10-ton press = 20,000 lbs. If you have a 3"x5" plate = 15 square inch. Hence, 20,000/15 = 1,333 PSI

Note: These numbers serve as a guide only. Results will always vary depending on temperature and material as well the press you choose. Refer to manufacturers recommendations for best results.
