Review on 🖨️ Enhanced Printer Filaments: Unmatched Durability for Resistant Printing by Michael Wiley

These are great little filters and you get so much for so little! I use them on all my 3D printers, both dust filters and oilers (avacado oil for higher print temperatures, vegetable oil works too but has a lower smoke point). They work great with PLA and PETG to beef up the hot end for a few dozen prints and when they wear out I put a new one in with just a few drops of oil and it's back in business. I only use 1.75mm filament. , but 3mm fits well, the housing has large holes at each end and the filter expands to accommodate it. I will be ordering more for future use!
