Wash bags are the central piece of gear used in the ice water extraction process, a solventless method of making bubble hash. Wash bags are nylon bags that fit inside of a bucket and stack one inside of the other, secured along the top rim of the bucket. Wash bags are made in various sizes to accommodate different amounts of cannabis material.

 

It may be tempting to save a few dollars by purchasing the most inexpensive rosin filter bags and bubble wash bags online. Dozens of companies have sprung up in recent years, opportunistically jumping on the solventless bandwagon with their ability to quickly manufacture low-quality products in hopes of appealing to undiscerning buyers. While their cut-rate bags might fit into even the slimmest budgets, they can quickly become counterproductive and even detrimental to your output.
