Read Blog👉 : A Comprehensive Comparison: NT-01 VS NT-02 Portable Oxygen Concentrators
NT-01 is a portable healthcare oxygen concentrator that can take good care of your and your family's health. It features an extremely lightweight, compact body, and a replaceable battery. All these make it suitable for portable use. It can also operate in the car with the included car adaptor, meeting your oxygen needs anytime and anywhere.
Upgraded NT-01
🔶Smart Inhalation Mode:
Our innovative "Smart Inhalation Mode" detects your breathing patterns to deliver oxygen precisely when needed. From 1-5L settings, this mode ensures oxygen is supplied only upon inhalation detection, optimizing the concentrator's efficiency and conserving power. If no inhalation is detected, the concentrator will seamlessly switch to delivering oxygen at a consistent, fixed frequency, guaranteeing uninterrupted support.
🔶Ultra Pulse Mode:
For higher oxygen demands, the NT 01 features the "Ultra Pulse Mode". At the 6L setting, the device automatically delivers oxygen at a rapid, fixed frequency of every 1.5 seconds, ensuring a steady and higher oxygen flow rate for users with more intensive needs.
🔶Replaceable Battery:
Unlike the previous model with a built-in, non-replaceable battery, the upgraded NT 01 now includes a convenient replaceable battery, allowing for extended use with spare batteries. The replaceable battery can be charged separately, ensuring that you always have a fully charged battery ready, providing uninterrupted oxygen therapy whenever and wherever you need it.
Lightweight and small size
Weighing only 6.5 lbs, the compact body and included carrying case allow you to be on the go, whether in the park, church, RV, etc., or on a trip without feeling the constraints of the machine. and hiking. It can accompany you all the time, allowing you to get close to nature and enjoy fresh oxygen.
Adjustable oxygen flow, high concentration
Provide 1-5L/Min of oxygen flow, at any flow, can provide up to 93%±3% oxygen concentration, and provide different oxygen flows according to the needs of the body. Intelligent and simple machine operation allows the body to quickly obtain more suitable oxygen.
Smart Touch & One-Key Acceleration & Timing
NT-01 has an intelligent large screen and touchscreen operation. The large-screen touch design allows the elderly with poor eyesight to operate better. At the same time, the operation is simple, with one key to start, and the machine has a timing function, according to your needs. The timing is based on the oxygen inhalation time, and the data is clear at a glance.
More physical oxygen production processes
This product uses air as raw material, a DC12V power supply or battery as the power source uses high-quality French imported molecular sieve, and a small oil-free air compressor, and uses an advanced pressure swing adsorption separation method (PSA method) to extract high-purity oxygen at room temperature. This method is a pure physical method, stable, safe and reliable, and can complete the absorption of outdoor air.
More safe and considerate design
In addition to meeting your oxygen needs, the Varon R&D team pays attention to safety during use. During use, the oxygen concentrator will warn if the temperature is too high or the oxygen concentration is less than 82%. In addition, the machine will record your cumulative use time, leaving a mark on your oxygen use time.

Good fit and looks great
Size: 11.5 Wide, Color: British Tan
Good quality and looks great, the only complaint is the lace is a bit short
But size is good and color is perfect too.

Narrow and small
Size: 10.5, Color: Black/City Skyline/Egret
I mostly chose these due to the foam rubber soles, as I was looking for a more comfortable sneaker. They are more comfortable and the quality looks decent, too, although I wish the leather wasn't so shiny.
The fit is quite narrow, and while they're okay for my narrow feet, I still wonder if the wider fit would have been better.
This is my 2nd pair of Cole Haan sneakers and the first were too small. So this time I ordered the next size up and the fit is not much different, so I'd say they run small all around. Despite that, they're big enough and are still quite comfortable.
Finally, the laces are too short. This is probably by design, so they're not dangling around, but I find them difficult to tie. They're nice, waxed laces, but they just need to be long enough to work with.
