After making sure your oxygen needs are met, and your oxygen concentrator fits your lifestyle and how long you need your oxygen therapy each day, you can narrow your search down to the most energy-efficient models. Energy efficiency is extremely important since this is an ongoing expense related to using your oxygen concentrator. You need to be able to keep your energy expenses as low as possible. There are a few oxygen concentrators that are the most energy efficient.
This is especially important if you need to use your oxygen concentrator for many hours out of the day. You don't want to get a model that uses more electricity for the same dosage, than what you could have gotten with one that uses less. Here are a few models that offer higher doses, with the least amount of energy used as possible.
Usually, the more energy efficient an oxygen concentrator is, the more likely it is to be quieter and newer looking. The more energy efficient a concentrator is, the better the internal system, which means it will also last longer.
The Perfecto 2 by Invacare is one of the most powerful and versatile stationary oxygen concentrators and is also one of the most energy efficient. It has settings from 0.5 to 5 LPM (liters per minute) in 0.5 increments, which makes it one of the best choices for those who need a more specific or half dose of continuous flow oxygen, greater than 3 LPM. At 3 LPM, the Invacare 2 uses 280 watts at an average. Naturally, if you are using a setting greater than 3 LPM, it will be more. In general, this is a small number for a stationary oxygen concentrator at 3 LPM.
The EverFlo is amazingly energy efficient. It uses a total of 350 watts at the highest setting, which is 5 LPM. It's settings are also from 0.5 to 5 LPM in .05 increments. At the setting of 3 LPM, it will only use an average of 280 watts. The fact that energy efficient concentrators are usually quieter and more efficient in general rings true with this model. It's only 40 decibels at most, which is as quiet as most portable models at much lower dosage settings.
This is an amazing innovation all around because you can fill up your portable oxygen cylinder at home, with the stationary oxygen concentrator filling system, and carry it with you when you leave the house. It only uses around 200 watts and will fill up to a 2 LPM cylinder, but there are also smaller sizes that won't take as long to fill.
