Sleep Restfully is great! I was in Houston for work and my CPAP machine broke. I found them online and placed an order late at night. By the next morning, they were already processing my order and had everything in stock (and ready for pickup by 11 am too)! On top of being efficient, they were so kind, pleasant, and helpful. Fantastic service and a great experience!

Key Features to Consider When Choosing a Concentrator

  • Flow Rate Capacity: Match your prescription’s required Liters Per Minute (LPM) setting to ensure your unit meets your daily saturation needs.

  • Weight & Battery Life: Evaluate how often you travel or spend time away from outlets to choose between single or extended double battery setups.

Common Oxygen Concentrator Questions

Do I need a prescription to buy an oxygen concentrator?

Yes. Federal regulations require a valid doctor’s prescription specifying your oxygen flow settings before we can fulfill your order. You can upload your Rx during checkout or let our support team reach out to your clinic directly.

Can I use a portable oxygen concentrator on a flight?

Most of our portable models are FAA-compliant for air travel. We recommend notifying your airline at least 48 hours before departure and carrying enough battery power to cover 150% of your total travel time.

What is the main difference between an oxygen tank and a concentrator?

Oxygen tanks contain a finite amount of compressed oxygen that requires regular refilling or replacement. Concentrators draw in ambient room air, filter out nitrogen, and deliver an unlimited supply of purified oxygen as long as the device has power.
