I believe there is a spacer from Pari that can be boiled or put in a baby bottle sterilizer and dryer.

I use the Ombra compressor and Aeroeclipse nebulizing cups as well. However, if you have a less powerful compressor, you might not want to use the Aeroeclipse cup because it requires more power and might burn out your compressor. In that situation, I would recommend the Pari Sprint cup as it, too, can be boiled or put in a baby bottle sterilizer and a dryer.
