CPAP Mask Leaking? Here's How to Fix It

Hello and welcome. If your CPAP mask is leaking, you're not alone — it's one of the most common CPAP problems. A leaking mask means you're not getting the full pressure you need, and it can wake you and your partner up at night. Step 1: Check your mask fit. Put your mask on while lying down in your typical sleep position. The mask should feel snug but not tight. If you feel air escaping around the edges, the seal is broken. Step 2: Inspect the cushion. Over time, CPAP cushions break down and lose their seal. Check for cracks, stiffening, or discoloration. Most cushions should be replaced every 1 to 3 months. Step 3: Adjust the headgear. Headgear stretches with use. Tighten the straps evenly — not just one side — until the mask lies flat against your face without gaps. Step 4: Try a different mask size. Mask fit varies significantly between sizes and styles. A nasal pillow mask may seal better if you have a narrow nose bridge. Step 5: Clean your mask daily. Oils from your skin break down the silicone cushion faster. Rinse your mask with mild soap and warm water every morning. If you've tried all these steps and your mask still leaks, it may be time to see a CPAP specialist or replace your equipment. Your local DME provider can help you get fitted properly.
