Are CPAP cushions universal across masks?

No. Replacement cushions must match the exact mask family and size. Use the replacement timing here only after you confirm the model.

Why do nasal pillows sometimes appear on shorter replacement schedules?

Manufacturer guidance can place nasal pillows on a more frequent replacement cadence because small silicone parts contact the face directly and can wear or become hard to clean.

Should I replace a cushion before the schedule date?

Replace sooner if the silicone is damaged, hard to clean, stretched, torn, or no longer seats correctly on the mask frame.
