While you may find Oxy2Mask on Amazon for sale, please know that we do not provide Oxy2Mask to any Amazon vendor. Because of this, we cannot guarantee the performance or quality of any product you purchase off Amazon or any other 3rd party ‘like’ site. Plus, we have heard instances of people buying medical products like Oxy2Mask off these sites, only to find they get shipped a used/soiled device, parts of a device, or a device that is broken. Buyer Beware! It is best that you obtain your Oxy2Mask products from a Southmedic authorized vendor to ensure you receive the quality you expect and need in an oxygen delivery product!
