@jerry22748 Yes, the $100 handheld ones are convenient, but they are not up to daily use, sometimes more than once a day. I'm not sure who the target market is, but it is not people who neb two or more times a day. And many cannot withstand sterilizing. I find it telling that none of the cheaper ones on the market have a warranty longer then 90 days.
Years ago, Philips mad a $300-400 dollar one that was pretty hardy, but they went out of the nebulizer business.
The one @scoop referred to is very pricy, it is a mesh one, but does have a small compressor base, and is pricy. We have had ours for over a year (2 of us use it with separate handsets) and it is proving to be reliable, fast & quiet. Compared to burning through multiple $50-70 ones in a year, I think it is going to be cheaper in the long run.

How long have you been trying to find a reliable mesh nebulizer?

@jerry22748 Jerry,
Good luck in finding a portable unit that’s available, reasonably priced, and lasts. I also used the “PARI Trek® S Portable Nebulizer System with PARI LC Sprint®: On-the-Go Therapy” but it stopped working during a trip (but several years of use), so I just bought an Omron NE-801 compressor w ac adapter to get by until we got home.

When I’m home I use the PARI Vios pro compressor for heavy use. It’s a work horse that has lasted 10 years! I replace the PARI LC sprint reusable nebulizer sets every 6 mo. Best, jessed
