The EverFlo Q is one of the smallest and most energy efficient home oxygen concentrators by Respirionics. You will get between 0.5 and 5 LPM (Liters Per Minute) of continuous flow oxygen in 0.5 increments, which means there are 10 settings in all. This is great for those who need a specific amount of LPM. The EverFlo Q is also ideal for those who need overnight oxygen, or those who need it for a few hours out of the day while they are sitting still.
You can count on this home oxygen concentrator not taking up too much room, with its slim design. It sits at 23 inches tall, 15 inches wide and just 9.5 inches deep, so you can tuck it in next to your chair wherever you are sitting, or roll it under the table and out of the way.
It also only weighs 31 lbs, which is as light as they come with home oxygen concentrators
of this capacity. There are wheels on the bottom and an easy to grip handle at the top of the unit, so you can easily roll it from one room to the other when you need to.
The EverFlo Q uses around a maximum of around 350 watts while on the highest setting, which is on the lower end of electricity usage for most home oxygen concentrators. The oxygen purity is around an average of 93%. This concentrator is also very quiet, at just 40 decibels, which is no louder than the hum of your refrigerator. It's also known for producing much less heat than other home oxygen concentrators that have the same oxygen capacity.
It only has 2 filters to replace every 2 years, so you won't need to worry about any maintenance on this machine. It's easy to operate, with just a few buttons you will ever have to push, located at the top of the unit.
