Using a home oxygen concentrator will increase your electric bill, but the AirSep Visionaire is one of the most energy-efficient home concentrators on the market. While most other units draw 350 watts of power when in use, the Visionaire draws only 250 watts. This energy efficiency helps you save money on monthly bills whether you're on a fixed income, still working, or retired. You can run it 24/7 without worrying about excessive electricity costs.

Weighing just 30 pounds and measuring 14.1" W x 20.8" H x 11.5" D, the AirSep Visionaire is one of the smallest and lightest 5-liter home concentrators available. It's small enough to tuck into a corner of the room or store in a closet, and you'll have no problems moving it from room to room. It comes equipped with caster wheels for effortless mobility and can be used with up to 50 feet of tubing, giving you the freedom to bring it to the living room, backyard, or bedroom without any hassle.

Running at just 40 decibels, the Visionaire is quiet enough not to disturb you while watching TV or sleeping. It features a 20,000-hour compressor and comes with a 3-year warranty for peace of mind. Maintenance takes 2 minutes a week at most—unlike other home concentrators, you don't have to clean or replace any filters. Simply wipe it down with a cloth dampened with warm water and mild soap once a week to prevent bacteria buildup and keep your machine running smoothly.
