It is normal that as a mask ages (especially when it is over a year old) the seal will leak as it wears. This is often an indicator that it is time to be replaced. However, if you mask is not very old and you still suffer from mask leaks, there are some way to help reduce this: Trim your facial hair. Thick beards & moustaches can cause your mask to have larger than acceptable leakage. Clean your mask. By cleaning the seal of your mask daily and the entire mask weekly, you will help keep the body oils & skin cells off your mask. A build up of these can cause your mask seal to leak. Ensure you are wearing it properly. If your mask is not sitting where it is designed to fit on your face, your mask leak will increase. If you are not sure if you are wearing it properly, check with your provider on the proper fit.
