Oxygen Concentrator 5 Liter Reviews





Home Oxygen Concentrator Review

5 Liter Oxygen Concentrators offer medium oxygen flow and are the staple for home oxygen therapy, delivering adequate oxygen flow for over 90% of oxygen patients. Normal oxygen saturation of the haemoglobin (SpO2) is at 95 to 98%. Acceptable oxygen saturation is at 90% but often patients can still do well on 88%.

DeVilbiss Oxygen Concentrator

While too little oxygen can be life threatening, too much oxygen can also be harmful. Too much oxygen saturation may suppress the respiratory drive. Symptoms of too much oxygen include headaches, sleepiness and confusion. Maintenance of an SpO2 of 90% or greater is the objective for the patient. The majority of oxygen patients require 2 liters per minute (LPM) or less to achieve an acceptable oxygen saturation. A determination of what is acceptable oxygen therapy for a specific patient should be determined by a physician. Therefore, a prescription is necessary for oxygen therapy in the United States.

This oxygen concentrator review examines the top ten concentrators on the market that offer at least 5 liters of oxygen therapy per minute. These concentrators, listed in alphabetical order are the Companion 5 from Caire, the DeVilbiss 5 Liter Concentrator, the EasyFlow5 from Precision Medical, the EverFlo and the EverFlo Q from Respironics, the NewLife Elite from AirSep, the Nidek Nuvo Lite Mark 5, the Invacare Perfecto 2, the Pure from Drive Medical and the VisionAire5 from AirSep. A side-by-side comparison of the Top Ten Home Oxygen Concentrators is provided below this review summary.

Smallest Size 5 Liter Oxygen Concentrator

Size matters! Large, heavy concentrators are difficult to move from room to room and take up too much space in your home. When moving your concentrator, larger concentrators tend to bump against furniture, door jams and walls. Small, lightweight concentrators are easier to move and require less of your valuable space. Some oxygen patients are too weak to move a heavy, bulky concentrator from room to room. Smaller, lightweight oxygen concentrators often require less shipping fees; and therefore, less of and expenditure when purchasing online.

The DeVilbiss 5 Liter Oxygen Concentrator offers the smallest size with just over 2000 cubic inches and weighing 37 pounds. The EasyFlow5 Oxygen Concentrator has the lowest weight at only 29.6 pounds, but has a significantly larger size than the DeVilbiss at over 3500 cubic inches. The second smallest concentrator is the Nuvo Lite Mark 5 at just under 2900 cubic inches. The "heavy beast" award goes to the AirSep NewLife Elite at 54 pounds with over 6500 cubic inches, nearly double the weight of the EasyFlow5 and over triple the size of the DeVilbiss concentrator. The chart below compares the top ten oxygen concentrators and ranks them by size, the smallest size is to the bottom of the chart and the largest is to the top. The red horizontal line indicates the average size for the concentrators, displaying seven concentrators with less size than the average. Weight for the concentrators is also displayed on this comparison chart with the average of 36 pounds indicated by the red verticle line. The five concentrators to the left of the average weight line have less weight than average. There are four concentrators that are in the "Blue Zone", indicating that they are better than average for less size and better than average for less weight. One concentrators is at the average average mark of 36 pound, six concentrators are better than average weighing less than the average, while four concentrators are heavier than the average.

Concentrator with the Lowest Power Consumption

With rising utility rates, finding an oxygen concentrator that is budget friendly to operate becomes increasingly important. This factor is particularly significant for those who run their oxygen machines 24/7. The Companion 5 Oxygen Concentrator leads in this category with an average power consumption of only 250 watts. The Nuvo Lite Mark 5 and the Perfecto 2 are second and third with 280 watts each. The "Power Hog" designation goes to the Drive Medical Pure Oxygen Concentrator at 360 watts. There is a four way tie for the second worst "Power Hog", requiring 350 watts to operate--the EasyFlow5, EverFlo, EverFlo Q and the NewLife Elite. The comparison chart below displays the 10 concentrators and their average power consumption. Four concentrators have better than average power consumption as shown below the red horizontal line indicating the average power consumption. The other six concentrators consume more power than the average of 322 watts.

Lowest Noise Concentrator

Noise is a significant factor for many oxygen patients. Even if the oxygen patient is OK with the noise, often their spouse is not. Oxygen concentrator engineers have been making progress on decreasing the amount of noise emitted from an oxygen concentrator while operating. Currently there is a four-way tie for first place at 40 decibels (dBA). The engineers at Caire/AirSep, Nidek and Respironics have made the most headway in decreasing the noise that oxygen compressors make while running. The honors go to the Companion 5, EverFlo Q, Nuvo Lite Mark 5 and the VisionAire 5. The chart below displays the safe region of noise between 1 and 50 decibels marked in green and the non-hazardous noise level marked in yellow. Nine of the ten compared concentrators are in the safe zone while one is slightly in the non-hazardous zone well below human conversation level.

Invacare Perfecto 3 Oxygen Concentrator

Best Selling 5 Liter Oxygen Concentrators

The DeVilbiss 5 Liter Oxygen Concentrator is the top seller at Vitality Medical. Its low price and feature rich benefits are difficult to beat. The second best selling is the VisionaAire 5 Oxygen Concentrator followed by the Invacare Perfecto 2. Invacare is the most searched for oxygen concentrator on the Internet followed by the Respironics EverFlo.

Best Performing 5 Liter Oxygen Concentrator

The DeVilbiss 5 Liter Oxygen Concentrator takes the top honors with the smallest size, highest concentration levels, and one of the highest output pressures. Producing concentration levels in a range of 90 to 96%, the DeVilbiss Concentrator's lowest concentration level stills falls in the "acceptable" SpO2 range. Several of the other concentrators slip down to an 87% concentration level on their low sides and one falls down to 85%. The ability of the DeVilbiss to produce this level of concentration while in the smallest sized concentrator is very significant. The Respironics EverFlo Series and the NewLife Elite take the second and third best positions respectively. The NewLife Elite has a range of 7 to 9 psi for output pressure, having the potential to offer the highest output pressure of all the 5 liter concentrators reviewed. The Pure Oxygen Concentrator and the DeVilbiss from Drive Medical offers the best operation at high altitudes at up to 13,123 feet above sea level. The chart below compares the maximum operational altitude for the top ten concentrators with the best performing concentrators on the left. The red horizontal line indicates the average max altitude, displaying 6 concentrators with above average performance and four concentrators with below average performance.

Bonus Features

Everyone likes to get a bonus, and getting something extra with your oxygen concentrator purchase is a big plus. This concentrator review gives the nod to the AirSep VisionAire 5 Oxygen Concentrator's optional nebulizer function. Many oxygen patients with multiple respiratory illnesses can benefit from this added feature. The engineers at Caire/AirSep are becoming the innovators in the oxygen concentrator arena.

Overall Best 5 Liter Oxygen Concentrator

The overall best home oxygen concentrator has to be the DeVilbiss 5 Liter Concentrator. This oxygen machine has the smallest size, highest oxygen concentration level, high output pressure and at the lowest price! The combination of these factors has made the DeVilbiss Concentrator the online best selling concentrator by a margin of 5 to 1 over its next closest competitor. DeVilbiss manufactures their concentrator in the USA, but has somehow managed to keep their costs down and to pass the cost-savings on to oxygen patients. The AirSep VisionAire 5 is noteworthy for being the second highest sales leader with its low noise, low power consumption and optional nebulizer. Third is the Invacare Perfecto 2 which is also the second lowest priced oxygen machine. It is likely that the DeVilbiss Concentrator will continue to lead in sales until the other manufacturers can bring their costs down.

Oxygen patients usually have many medical expenses that dive into their bank accounts. Getting a significant cost savings on their medical oxygen needs is a huge break that is difficult to ignore. While the DeVilbiss leads the concentrator market by a significant margin, many of the other concentrators offer special features that make them appealing to segments of the oxygen therapy market.
