Welcome to HealingWell!
I use the OMRON CompAir Elite. I bought mine at a local pharmacy for about $100.00. I bet you could find one at a pharmacy where you live. I did find a site so you can see what all it does. This unit works so much faster and quieter than the older units, it is great for kids.
I told a friend about it a couple of years ago because she had a little boy who had to use it every morning before he went to daycare. She said it made all the difference in the world in their mornings, she didn't have to fight with him to use the nebulizer.
I have listed this website because I am not involved with this company, just wanted to show you the unit.

It has given me a feeling of safety, knowing that I can pull over and use it in the car and not have to worry about if I can make it home before I have an asthma attack. It truly does work much faster than the older machine I started out with. I rarely leave home without it.
Good luck!
