Find answers to common questions about oxygen concentrators, shipping, warranty, returns, and more.
An oxygen concentrator is a medical device that draws in ambient air, removes nitrogen, and delivers concentrated oxygen to the user. Unlike oxygen tanks, concentrators generate oxygen continuously and never need refilling — they simply require a power source to operate.
Home oxygen concentrators are stationary units designed for continuous use at home. They typically offer higher oxygen output and continuous-flow delivery. Portable oxygen concentrators are lightweight, battery-powered units designed for mobility and travel. They often use pulse-dose delivery to conserve battery life while maintaining therapeutic effectiveness.
