Val You are correct, the Omron nebulizer does not require oxygen, it has a built in air pump that will put out 24 psi. This is the same model NE-C16V that I have seen advertised on a few other sites for $95.00. At $54.95 it is a real bargain, unfortunatly, I live in Canada, and with exchange and border taxes it costs me over $90.00 Canadian. I still think it is a good buy.
Go to the www.drugstore.com site and type the word nebulizer in the search box in the top left corner, you will then see this nebulizer plus an ultrasonic one for $149.00. If you click on the picture you will the get the details on the units. To Nina's question about face mask. The Omron model comes with a mouth piece instead of face mask. You breath in and out through the mouth piece. works well. Yes you can use it hands free Dave
