Due to the Food Drug Administration (FDA) regulations, once any product is open or taken out of its original packaging, it is no longer returnable. Therefore in order to comply with these regulations, if either any equipment or any supplies have been open and/or used, the item(s) is no longer returnable – there will be no exceptions.
This is nothing new to members here except for us newbies. Of course you don’t want to pass contamination, viruses and germs to next user so this is for safety, and I totally get that. On line suppliers state ”our expert trained staff stands by ready to assist you to get the right mask”. As an analogy, imagine going to a shoe store, having salesman measure your feet with a Bannock Device (Google it), then must BUY shoes before trying them on. Once on your feet, no returns if pinches, wide, wobbly.
So guess I will have to buy locally where someone can measure my face, use nose cutouts etc and cross my fingers mask works, minimal leakages, comfortable at night. If I hit the jackpot then I can buy online parts liners etc with a prescription (assuming my sleep doctor/nurse will give me another one)
Wa, wa, wa poor little me.
