<s>[INST] How will the filter be cleaned? [/INST] The filter will not require cleaning or replacement. A thin biocompatible coating is applied to the filter membrane to help prevent clogging and blood clots. The constant flowing of blood over the coated filter surface also helps keep the membrane free of debris. Source: UC San Francisco. Link: https://pharm.ucsf.edu/kidney/device/faq. Field: Nephrology.
