Ask an Oxygen Specialist: "How long do portable oxygen concentrator batteries last?"

Great question -- and one we get all the time.

Battery life varies by model and by how much oxygen output you need, but here are some general guidelines:
- Most portable concentrators run between 3 and 8 hours on a single battery
- Higher flow settings use more power and reduce battery life
- Carrying a second battery or an external battery pack can extend your range significantly
- Many users use an external battery charger to charge the extra battery while using another one.

If you travel frequently or spend long days away from home, battery life is an important factor when choosing a concentrator. Our Oxygen Specialists can help you match a model to your specific routine.

Happy Earth Day! Today we celebrate the air around us -- and for our community, clean air is more than a cause. It is personal.

For people living with COPD or on oxygen therapy, air quality can have a real effect on how you breathe and how you feel day to day. On days when outdoor air quality is lower, staying indoors, keeping windows closed, and using an air purifier can all help.

Here are a few simple ways to support your breathing on Earth Day and every day:
- Check your local air quality index before heading outdoors (AirNow.gov is a great free resource)
- Keep indoor air clean with regular filter changes on your concentrator and home HVAC system
- Stay well-hydrated to help support your airways
- Talk to your doctor about any seasonal changes in your breathing

We are proud to help our community breathe easier. If you have questions about your oxygen equipment, our Oxygen Specialists are here at 866-245-2349.

Spring is fully here and that is worth celebrating. Whether you are stepping outside for a short walk, sitting on the porch with a cup of coffee, or simply opening a window to let the fresh air in, moments like these matter.

If oxygen therapy helps make those moments possible for you, we are glad to be a small part of that. Our Oxygen Specialists are always here if you have questions about your equipment. Give us a call at 866-245-2349.
