Inogen makes some of the most recognized portable oxygen concentrators (POCs) for supplemental oxygen therapy. A concentrator pulls in room air, filters out other gases, and delivers oxygen-enriched air through a nasal cannula, so you are not tied to heavy oxygen tanks. Oxygen therapy is prescription only in the US, and an Inogen unit is yours to own rather than rented. This page covers the Inogen models Sleeplay carries, how they differ, and what to weigh on cost and coverage.

Inogen models we carry

Sleeplay stocks both Inogen portable concentrators (pulse dose, for mobility) and Inogen home concentrators (continuous flow, for higher-flow needs):

• Inogen Rove 6: portable, pulse dose with 6 flow settings, 4.8 lbs, up to about 12 hours 45 minutes on an extended battery.
• Inogen Rove 4: portable, pulse dose with 4 flow settings, 2.9 lbs, up to about 5 hours 45 minutes on an extended battery.
• Inogen One G4: one of the smallest portable concentrators, pulse dose with 3 flow settings, 2.8 lbs.
• Inogen At Home: a stationary home concentrator delivering continuous flow from 1 to 5 LPM, 18 lbs.
• Inogen Voxi 5: a stationary continuous-flow concentrator, 1 to 5 LPM, for higher-flow home use.

See each product page for full specifications.

Pulse dose vs continuous flow

Pulse-dose units (the Rove 6, Rove 4, and One G4) release a measured burst of oxygen each time you inhale, which keeps the device small and the battery light, ideal for travel and daytime mobility. Continuous-flow units (the At Home and Voxi 5) deliver a steady stream measured in liters per minute (LPM), which many higher-flow and nighttime prescriptions require. Your prescription tells you which type and flow setting you need.

Travel and battery life

Inogen portable concentrators meet the FAA acceptance criteria for carriage and use on board aircraft, so they can be used in flight; confirm your airline's policy before you fly. Battery duration depends on the model and flow setting, and extended batteries add hours of run time. Pair a portable unit with a carry bag and a spare battery for longer days out.

How to choose an Inogen concentrator

Start with your prescribed flow type and rate: a pulse-dose portable if you are mobile, or a continuous-flow home unit for higher flow. Then weigh size, battery life, and travel needs.

Cost, insurance, and prescription

A valid prescription is required to buy any oxygen concentrator in the US. Inogen units are FSA and HSA eligible, and Medicare or private insurance may cover oxygen therapy for qualifying patients, so check your plan. Unlike rental programs, the concentrators here are yours to keep. See each product page for current pricing and financing options.
