EspañolOxygen Therapy Equipment, Made Simple
Portable and home oxygen concentrators, plus batteries, cannulas and parts — genuine equipment, tested by our team, shipped free across the U.S. or picked up at our Miami showroom.
For people managing COPD, low blood oxygen, recovery, or an active life on the go — new, Open Box, and Certified Pre-Owned.
Portable or home oxygen — how to choose, and where to buy
- What it is → Oxygen therapy delivers extra oxygen through a concentrator — a machine that filters room air. Portable units keep you mobile; home (stationary) units run continuously at higher flow.
- Portable vs home → Choose a portable concentrator for travel, errands and staying active (mostly pulse-flow, carried in its bag). Choose a home / stationary concentrator for overnight use and higher continuous liter-flow (5L or 10L).
- How to choose → match your prescription (pulse dose or continuous liters), then weigh battery runtime, weight and noise for how you live.
- Where to get it → American Oxygen sells, rents, and repairs oxygen equipment — new, Open Box, and Certified Pre-Owned — with free U.S. shipping and a Miami showroom.
Oxygen concentrators are prescription devices. American Oxygen is a retail supplier, not a medical provider — talk to your doctor about your oxygen needs. Certified Pre-Owned and Open Box units are inspected and tested; warranty by American Oxygen. Not sure which fits? Call (786) 755-8063.

Emergency oxygen — ready when seconds count
Portable, high-flow oxygen for first-aid and emergency use — offices, gyms, schools, dive shops, first responders and home emergency kits. Different from a therapy concentrator: these are grab-and-go units for a crisis, until professional help arrives.
- Ready for an emergency → a simple, high-flow oxygen unit you keep on hand for first-aid situations — grab it, open the flow, and deliver oxygen until professional help arrives.
- High flow → choose fixed 6 LPM, 6 / 12 LPM, or a regulator with flow positions up to 25 LPM.
- Ships “Empty” → the unit arrives without the oxygen fill (light to ship); fill the cylinder at any local oxygen supplier and it’s ready.
- Three systems → SoftPac (light soft case, M9), OxygenPac (larger hard case, M20), and the complete StartSystem station.
Emergency oxygen is for temporary emergency use until professional help arrives — it is not a substitute for prescribed oxygen therapy. Questions? Call (786) 755-8063.

Five things to match before you buy
Start with your prescription, then fit the equipment to your life. When in doubt, call us or ask your provider.
- Flow type — pulse dose vs. continuous flow. Your prescription tells you which you need.
- Output / setting — the unit has to cover your prescribed pulse setting or liter-flow.
- Battery & runtime — how long you'll be away from an outlet matters for portables.
- Weight & carry — comfort on the shoulder for daily use and travel.
- Noise & home use — quiet enough for overnight if it's a home unit.
Only need oxygen for a trip or a few weeks? Rent instead.
If you're visiting Miami, recovering, or just don't want to buy yet, a rental portable oxygen concentrator may be the smarter move — no big upfront cost, and you can switch to buying later.
