I am using a resmed Quattro air

Hi can anyone help me please. I am very new to this game and until now have no problem with the mask fit. We are on holiday in Devon so can't pop into the clinic. I wash the mask every day fit it in exactly the same way but can only get a sad red face for mask fit. Is it all right to use it any way ...

Thank you so much am so pleased it is helping you. Thank you also for your tips
