Just had a quick look and the Sonovia mask retails for $45. Granted it's reusable but I can't see the mass market spending that kind of money on a mask.
If I remember correctly, the P2F mask is expected to retail fairly cheap. So whilst the consumer may end up spending the equivalent over time, £1 single use are more palatable than a one-off £35-40.
