At first glance, it might seem like the Everflo and the Everflo Q look like the same stationary concentrator. Although they are very similar, there are still a few key differences that will make an impact on whether or not each one is right for you. They are both low maintenance and small and a great choice for those who need to use oxygen at home. These are both stationary oxygen concentrators, which means they run on AC power only.
The Respironics Everflo Q
The Everflo Q was sold as being one of the quietest stationary oxygen concentrators on the market, for the oxygen capacity. It's only as loud as 40 decibels and goes up to 5 LPM (liters per minute) of continuous flow, in 0.5 increments.
These half doses are great news for those who need a more specific dosage of continuous flow oxygen. The low noise level makes it perfect for those who need to use it during the night, or just anyone who wants to be able to sit and watch TV without having to turn up the volume any louder than they should need to.
As actually a more powerful stationary model, even though it's quieter, it uses as much as 350 watts of electricity. This is a little more than some of the other small stationary models, but it's still considered to be “green”, or environmentally friendly when it comes to stationary oxygen concentrators. This is a great alternative for those who need no more than 5 LPM of continuous flow oxygen, who want to cut down on their energy bill.
The Everflo Q is very low maintenance. You'll be able to access the gross particle (air inlet) filter yourself in a matter of a few minutes, and it only needs to be changed around once a year. The inner filter only needs to be inspected during routine maintenance, and doesn't get anywhere near as dirty or as worn out as the gross particle filter, which is the filter that catches dust, dirt and spores in the air.
The Respironics Everflo
The Everflo has been found to be a little louder, but not by much. Even so, the Everflo can be still be compared to the noise level of an average kitchen refrigerator when it turns on. It's a low white noise, and many people get used to it pretty quickly.
It also uses less electricity than the Everflo Q. The Everflo's system is a little less weighty, so it uses around 100 watts less than the Everflo Q. Not much of a toss-up when it comes to saving money on your electric bill in the long run.
The Everflo Q's system is stronger and might last longer than the Everflo, however. It can be hard to compare and choose from the two, but the Everflo Q might be the better choice out of the two very similar models.
The Everflo is also tough and hard to break, while being very simple and easy to use. People with bad eyesight love the Everflo because of its simple controls and stark contrast against the blue color of the outer cabinet.
