Inogen 5L at Home vs. Respironics SimplyFlo Concentrator Comparison

Whether you’re recovering from a sickness, a recent surgery, or you have Chronic obstructive pulmonary disease (COPD), an oxygen concentrator “delivers an extra supply of oxygen into the body”, which can help with shortness of breath and other COPD symptoms.

If you’re in need of oxygen at all times or while you’re sleeping, a stationary oxygen concentrator might be a good fit for your at-home needs. However, with so many oxygen concentrators on the market today, which one is best for you? Even though options might make the buying decision hard, Oxygen Concentrator Store offers a variety of oxygen machines to ensure you’re matched with the perfect oxygen product.

Today, we’re comparing two home oxygen concentrator models: the Inogen At Home 5L Concentrator and the Respironics SimplyFlo Home Concentrator. We’ll give you an overview of each product’s oxygen flow, size, and battery life. These factors may help you choose the right oxygen machine for you.

Similarities and Differences between the Inogen at Home vs. SimplyFlo:

Oxygen Flow Settings

There are two main options when it comes to a product’s oxygen flow settings: continuous flow and pulse flow. On-demand pulse flow delivers oxygen only when you inhale through your nose[3]. Both the Inogen At Home 5L and Respironics SimplyFlo Home oxygen concentrators are continuous flow oxygen systems. The Inogen At Home 5L features five different settings, ranging from one to five, each with a different amount of liters per minute. The Respironics SimplyFlo can deliver up to two liters of oxygen per minute.

Summary: Although both oxygen machines offer continuous flow settings, the Inogen at Home model has five settings to choose from, up to five liters per minute. The SimplyFlo model only has two settings, with a maximum of two liters per minute.

Comparing the Inogen 5L Home Concentrator and the Philips Respironics SimplyFlo Home Concentrator

Weight and Size

One main difference between the Inogen at Home and the SimplyFlo unit is the size of each. The Inogen model is twice the size of the SimplyFlo model. The Inogen weighs in at 18 pounds and is 13 inches by seven inches by 16.5 inches [4]. SimplyFlo is only eight pounds and is 11.5 inches by six inches by 10 inches [5].

Summary: The Inogen model is twice as heavy as the SimplyFlow model. However, both machines are intended mostly for stationary purposes, so you likely won’t have to carry either for very long.

Battery Life

Because each of these two oxygen concentrators is a stationary model, they are intended to be plugged into an electrical source. They aren’t intended to be portable machines, so the battery life for these models doesn’t exist. However, one benefit of a stationary oxygen machine is that you won’t have to carry it with you unless you move it into a different room of your home.

Summary: Both models come with a power cord to plug into the wall, rather than coming with a rechargeable battery.

Additional characteristics:

The Inogen model has a noise level of 40 decibels, which outputs about the same amount of noise at a desktop computer [4]; the Respironics model is only a tad louder, at 50 decibels [5]. Each model has a three-year warranty, which allows for some peace of mind.

SimplyFlo Update

Respironics discontinued manufacturing the SimplyFlo in May 2109. The information above is still accurate and can be used to assess refurbished machines that can be in the marketplace. Additionaly, while the SimplyFlo is a similar product in size and performance, there are additional home concentrators that are available that can meet the oxygen needs for a person. Respironics offers the Everflo Q as home concentrator as well which can be reviewed here.
