Filtering your rosin.

Rosin Press Filters

The types of filters used for pressing rosin is highly debated at the time of this publishing. From the Micron size to the actual material the filter is made of, it seems there's no clear answer to this question. Maybe that's due to the companies that are selling the different types of rosin press filter bags are the ones putting out the info. Each one lists the pros and cons of the various types of filters with the ones they sell always beating out the others. They have a vested interest so we suggest taking their advice with a grain of salt. Below you'll find information we found through our experience.

  • Coffee rosin press filters.

Coffee filters are one of the most affordable filters out there for pressing rosin. They can't withstand too much pressure but they do work great for sift, ice water extracted or

dry ice extracted oils. We've even seen them used to remove contaminants from rosin already pressed. No matter what filters we use, you're going to have a blowout from time to time. If/when that happens we can collect the area that's been contaminated and place it into a folded up piece of coffee filter and press at a low temperature. The results are amazing for something so readily available.

  • Nylon rosin press filters

Nylon rosin press filters are probably the most widely used rosin press filter on the market. They come in multiple sizes and are very affordable for the average home user. The filters come in different micron size that allows us to work with different materials from dried herbs to extracts with great results. Nylon is also a stronger fabric than polyester so one could assume that nylon rosin press bags would have fewer blowouts than their polyester counterparts. Nylon mesh is what's typically used in ice water extraction bags as well so it's a fabric that's already known for extracting oils with great


  • Polyester rosin press filters

Polyester rosin press filters are very similar to the nylon rosin press filters. Polyester filters come in the same sizes and perform the same tasks as the nylon filters. Polyester is a cheaper material than nylon so one would assume that polyester filters would be the cheaper of the two. While nylon and polyester filters are very similar the stronger material with more stretch is nylon. Polyester's main benefit over nylon is it does not absorb water. One could assume if it does not absorb water it won't absorb your oil.

  • Stainless Steel rosin press filters.

Stainless Steel rosin press filters are perfect for those who only produce their own medicine/oils since you can get more than one use out of them. They're the strongest rosin press filters on the market but also the most expensive. If we're running any kind of production, we'll stick with the polyester or nylon bags as buying stainless steel filters will eat into our overhead. Stainless steel rosin press filters come in the same sizes as typical fabric rosin press filters. Unlike fabric filters, these bags may cause pitting on the rosin plates over time.
