Simultaneously, the built-in Nebulizer interface allows for at-home nebulizer treatments, improving your breathing quality. What sets the NT-04 apart is its incredible reliability with a remarkable 72 hours of uninterrupted operation.

  • Automatically Humidify Oxygen

Compared with traditional oxygen generators, the most prominent function of VARON household machine NT-04 is that it can automatically humidify oxygen without repeatedly adding water. Many patients suffer from nasal dryness due to long-term inhalation of oxygen. Therefore, when we develop this machine, we attach more importance to the humidity of the produced oxygen so that you can breathe oxygen more comfortably.
At the same time, oxygen is purified and humidified through high-quality molecular sieves of strong adsorption and 10-stage filtration before finally being provided to users, ensuring that every breath you take is clean.

  • Smarter & Lighter
NT-04 is VARON's lightest household oxygen machine, only 10.58lb. It also has a smaller size and a more modern appearance. The built-in backlight lets you see the working status clearly at a glance. You can choose to turn off the built-in backlight when you sleep at night, making you rest more at ease. It is a must-have machine for many people's home oxygen therapy.
