I question the authenticity of these
They do the trick, don’t get me wrong. However, I notice some differences in these compared to the original one that came with the pari nebulizer. First, they are misshapen and kind of flat. I figured over time and use, they would get their round shape back but they haven’t. Also, my daughter started to develop a little rash on both sides of her face just outside of her mouth, exactly where the plastic touches.  That never happened with months of use with the original.
