There are no chemicals or dyes in the 100% polyester mesh screens. They are food grade and safe to use for edibles oils or tinctures. They are made from solvent resistant material and can be used with solvent extraction processes for herbal and medicinal plants.

Screen filters all measure 5”X5″ and are perfect for use with various botanical extraction and filtration processes; mason jar, rosin tech press, oil extractors etc. The screens can be cut smaller to fit your precise extraction or filtration method measurements. Each screen features a color coded mark to make identifying the different micron sizes easy. The size indicating mark is located in the corner and will not interfere with filtering. Each square is heat sealed to ensure the pore size is consistent during and after each use.  They are heat cut to prevent the edges from fraying.

Tips: Wacky Willy is often asked about the use of coffee filters and cheese cloth; please note that both will absorb the liquid you are trying to extract, reducing the maximum yield from your extraction process. They also have a tendency to tear, releasing plant matter into your concentrate, and will need to be replaced after each use. Stainless Steel Screens can be stiff making them slightly more difficult to work with, and are more expensive. Wacky’s 100% mesh polyester screens are extremely durable simple to wash and reuse.

Care and cleaning instructions:
Do not allow plant matter to dry on the screens. Always wash and rinse well with alcohol, then dry thoroughly.
