Which types of contaminants are filtered out from the water used in dialysis?

Bacterial endotoxins are indeed a significant concern in dialysis, as they can have serious health implications for patients undergoing treatment. These endotoxins are components of the cell wall of certain bacteria and can trigger severe inflammatory responses in the body. In the context of dialysis, water purification is crucial, and systems are specifically designed to remove these harmful contaminants from the water used in the process. Proper filtration processes, such as reverse osmosis and the use of ultrafiltration membranes, are effective at eliminating bacterial endotoxins, ensuring the safety and efficacy of dialysis treatment.

The other options don't represent the same level of health risk or relevance in the specific context of water contamination for dialysis. Aqueous salts, while they are present in water, are often necessary for electrolyte balance and not harmful in the context of dialysis when well managed. Water softeners are used to treat hard water but do not actively filter out contaminants harmful to dialysis patients. Rust can indicate issues with water quality but is not specifically the focus of filtration in dialysis compared to the more critical removal of bacterial endotoxins.
