What is the best inhaler nozzle to buy?

Hi , and welcome! I see you are a new member here, having joined today, late this afternoon. We are glad to see you are already engaging with the community through this, your first post.
This is a good question! Before I can help you with an answer, I'd like to make certain we are talking about the same piece/part. Are you referring to a medication nebulizer system? If so, this may entail the difference between utilizing a mouthpiece or a mask. Are you referring to a metered dose inhaler (MDI) device? If so, this may be talking about whether to use a spacer (sometimes referred to as a medication holding chamber), or not. Are you referring to a steamer of some kind (like a Nettie pot)? This may be more of a proprietary piece the particular device uses.
Are you able to provide any additional information?
I will look forward to your response.
All the best,
Leon (site moderator asthma.net)
