Buying a portable oxygen concentrator (POC) is a bigger decision than most medical purchases — it shapes where you can go and how long you can stay there. This guide walks you through the process from prescription to first outing.
Step 1: Start with your prescription
Every oxygen concentrator is a prescription medical device. Your physician will specify a delivery method (pulse dose or continuous flow) and a flow setting. This single line of paperwork determines which machines are candidates, so get it first. Our team verifies prescriptions within one business day — see our prescription policy.
Step 2: Pulse dose vs. continuous flow
Pulse-dose units sense your inhalation and deliver oxygen in measured bursts — this efficiency is what makes 3–5 lb machines possible. Continuous-flow units stream oxygen constantly and are typically larger. Most active users on settings 1–6 are well served by modern pulse-dose machines like the Inogen Rove 6.
Step 3: Weigh the weight
A concentrator you won't carry is a concentrator that doesn't work. Under 3 lbs (like the Rove 4 or Belluscura X-PLOR), carrying feels incidental. At 4–5 lbs, a purpose-built backpack makes all the difference.
Step 4: Do the battery math
Take your typical longest outing, add 50%, and make sure the machine reaches that number at your setting — not setting 1. Battery specs are always quoted at setting 1, and runtime roughly halves every two settings up. Extended batteries and spares close the gap.
Step 5: Check the travel boxes
If you fly, confirm FAA approval (every concentrator we sell has it), plan battery for 150% of flight time, and notify your airline about 48 hours ahead. Keep your prescription with your boarding documents.
Step 6: Budget honestly
Quality portable concentrators run from about $1,600 to $2,400 at outlet pricing. Factor in a spare battery and annual filters. Beware of prices that look too good — grey-market units often arrive without valid warranties. Every unit we sell is factory-sealed with the manufacturer's full warranty.
