Question: what is the difference between high flux and low flux dialyzer?
Answer: High flux dialyzer is made of cellulose membranes with a higher permeability compared to low flux dialyzers. The clearance of toxins with medium and high molecular weights, such as β2-microglobulin, and phosphorus that accumulate during CKD, is higher in high flux dialyzers than in low flux (17,18).
