PortaOxy is a professional brand dedicated to home oxygen concentrators and portable oxygen concentrator products. We exist for one simple reason: to make daily breathing support easier, more reliable, and more comfortable for the people who depend on it.
Our brand philosophy is “See Further, Live Freely.”
To us, oxygen therapy is not just about a machine. It’s about restoring confidence, independence, and peace of mind. We believe that with the right support, people can continue to enjoy everyday moments, stay connected with loved ones, and live life on their own terms.
Long before PortaOxy became a brand, our team had already spent over 8 years in the oxygen concentrator industry, working closely with products, markets, and the real users. That experience shaped who we are today. Every product we offer is carefully selected, tested, and refined based on what truly matters to our customers: ease of use, safety, reliability, and comfort at home and outdoors.
We don’t stop at selection alone. PortaOxy actively participates in new product development, continuously improving design and performance by listening to customer feedback and understanding real-life needs. Our goal is to create portable and home oxygen concentrators that feel less like medical equipment—and more like a trusted part of everyday life.
Beyond products, we believe a responsible brand should give back. As part of our commitment to making the world a better place, a portion of every PortaOxy oxygen concentrator sold is donated to the Red Cross to support humanitarian and medical relief efforts. While our contribution may be small, we firmly believe that meaningful change begins with consistent action and genuine care.
At PortaOxy, serving our customers means more than delivering a product. It means standing beside you, supporting your journey, and doing our part—however modest—to help build a healthier, more compassionate world.
