FAQ: Choosing the Best Portable Oxygen Concentrator
Which machine is actually the best?
There isn't one "perfect" machine for everyone. If you need a constant flow, go with the NT-06. If you want something very light for traveling, the VP-8 Lite or the NT-08G are usually the favorites.
Is pulse flow better than continuous flow?
Pulse flow saves battery because it only gives oxygen when you inhale. This makes the machine smaller and the battery last longer. Continuous flow is better for people who breathe through their mouths or need a steady stream while they sleep.
Are these machines going to be loud?
Modern machines are built to be much quieter than the old ones. Most of these sound like a soft hum or a quiet fan, which makes them easy to use in a theater or a quiet restaurant.
