One of the most common complaints of CPAP users are that their mask leaks. It is a very common issue and the following tips are common reasons their may be a leak and what to do about it

  1. Clean your mask regularly: If your mask used to fit well but now leaks, facial oil or dirt may be compromising the seal. To prevent this, it is important to regularly clean your mask and CPAP machine using warm, clean water, mild soap or baby shampoo, clean, dry towels, and a sink or tub. Cleaning your mask every day can reduce the risk of leaks and prevent the buildup of bacteria, mold, dust, and germs that could cause pneumonia or sinus infections.
  2. Put on your mask after lying down: The mask seals fine when you first put it on, but then it breaks when you sleep. This may be because facial muscles relax once you fall asleep, which can change the shape of your face. Try putting the mask on when you are in the sleeping position to prevent this from happening.
  3. Adjust the fit while lying down: Your mask should fit snugly, not overly tight or loose. It also shouldn't cause headaches or pain or leave marks on your face after you've been awake for more than two hours. Adjust your mask when you are lying down as your face shape is different from when you stand or sit. Tighten the straps until your mask feels snug and secure.
  4. Make sure your mask is right for your sleeping position: We all have different facial structures, and before purchasing a mask, it is essential to try on a variety of styles and sizes to find the one that best fits your face. Also, consider your favorite sleeping position as one mask isn't appropriate for all. For example, side sleepers may require a nasal mask or nasal pillow mask, whereas stomach sleepers may need a nasal pillow mask.
  5. Discuss your CPAP air pressure with your doctor: High air pressure can cause masks to break their seal, leading to leakage. Your doctor will prescribe your air pressure setting, but you can talk to them about adjusting it if necessary. If your CPAP machine has a ramp feature, use it to gradually increase the pressure to your prescribed setting as you sleep.
  6. Replace your cushion or mask: Sometimes, just cleaning your mask doesn't do the trick. You may need to replace the cushion and even the mask itself. Regularly replacing your mask can improve the seal and help you get a better night's sleep.

By following these simple tips, you can fix the most common reasons for mask leaks, improve the effectiveness of your CPAP treatment, and get a better night's sleep.
