The Innospire Go portable mesh nebulizer I'd no longer manufactured. Phillips had issues with it leaking after a too-short time that it was unable to resolve, so I dropped the product.

As of today, there are one or two very high-priced mesh nebulizer available - one must be bought from Europe.

The ones on Amazon have not proven worthy for daily use, and especially not use with saline solutions. The screens soon clog with salt crystals and are too fragile to brush. Others are not made to be sterilized.

For travel I use an Innova portable compressor with hose and tubing, plus a charger. My current one is over 2 years old and going strong. It's predecessor was borrowed by my daughter, and just had to be replaced this Spring after over 4 years. The entire package weighs well under 2 pounds and is great for travel. The battery lasts over 2 weeks of daily use, and recharges in a few hours.
