Portable Oxygen Concentrator Warranty – Why Your Dealer Is So Important

Think purchasing a portable oxygen concentrator is a once-and-done transaction? It’s not.

Chances are your portable oxygen concentrator will need service sometime during the warranty period. Getting warranty service can be a little bit tricky, and sometimes it is downright hard if you don’t have a good dealer. Here’s the scoop:

If your unit alarms or malfunctions, your first thought might me to call the manufacturer. The problem is you are not their customer; the dealer is. Therefore, the manufacturer will usually provide only limited assistance and they will refer you back to your dealer. If you do not know who your dealer is, they will be able to tell you if you give them the serial number on the unit.

It’s a little bit like purchasing a car. You never buy a car from the manufacturer directly; always from a dealer. When your car has problems the manufacturer will not provide any assistance. You have to go back to the dealer. However, unlike an auto dealers who can handle warranty work no matter where you bought your car, a portable oxygen concentrator dealer can usually only help with warranty service for units they sold. The reason is that many manufacturers will only accept a warranty claim from the original customer which is the dealer that bought the unit from them. There are exceptions, of course. Invacare and Respironics are very willing to allow any authorized dealer handle a warranty claim. SeQual, Inova, and Oxlife are fairly willing. AirSep and Inogen are sticklers, and rarely allow anyone but the original dealer to request warranty repair.

If your dealer is helpful, then you have no worries. However, if your dealer is out-of-business, or rude and unwilling to help with your warranty repair, you may have a hard time finding a another dealer to help. Since dealers make no money by requesting warranty repairs, many are unwilling or financially unable to assist anyone but their own customers. Some are willing to help people in a bind and may help for a reasonable flat fee and shipping charges to cover the cost of their time. Still others will charge exorbitant prices for shipping.

What does all this mean to you? A good dealer is the key to continued satisfaction with your portable oxygen concentrator purchase.

When choosing a dealer for your portable oxygen concentrator purchase, here are several indicators to help determine if the dealer will be as helpful with service as they are with the sale:

  • The company is an authorized dealer for the manufacturer.
  • The company is a highly rated member of the Better Business Bureau.
  • The company specializes in portable oxygen concentrators. “Big box” medical supply companies may have lower prices, but often provide poor service.
  • The company has business longevity. There are no guarantees that a company won’t go out of business, but long-established businesses are usually a safer choice.
  • The company has non-pushy sales people. Sales people who are more interested in helping you make the best choice than in their next commission check are usually backed by a company that cares more about customers than sales quotas and are probably more willing to provide future support.
  • The company can supply a loaner unit for you to use while your unit is being repaired.
How Many Batteries You Need for Air Travel

For many oxygen users, their first interest in a portable oxygen concentrator arises when they wish to travel by airplane. Whether for a vacation abroad, or a trip across the country to see their newest grandchild, oxygen users are no longer bound at home, but are free to travel the world. With manufacturers ensuring that their portable concentrators are approved by the FAA, air travel is now accessible for most oxygen users.

The FAA requires all airlines to allow the use of portable oxygen concentrators, but the airlines are not required to provide electricity to power your unit. Instead they require that you have sufficient battery power for the flight. Thus, when traveling with a portable oxygen concentrator one of the most important considerations is the number of batteries you will need for your flight.

Most airlines require sufficient battery power to last 150% of the flight time.For example, if the flight time is four hours then you would need six hours of battery time (4 x 150% = 6).

Once you determine how much battery time your flight requires, then you can calculate the number of batteries you will need. Let’s look at a couple examples.

Battery Example #1 – Inogen One G3

Flight time – 5 hours
Flow setting – Setting 2

First, let’s do the math for the flight: 5 hour flight x 150% = 7.5 hours of battery time required.

Now let’s look at our battery options: the Inogen One G3 offers an 8-cell battery that lasts 4 hours on setting 2, or a 16-cell battery that lasts 8 hours on setting 2. So for our flight we would need either two 8-cell batteries or one 16-cell battery.

Battery Example #2 – SeQual Eclipse 5

Flight time – 4 hours
Flow setting – Setting 2 LPM (continuous flow)

Again, let’s do the math for the flight: 4 hour flight x 150% = 6 hours of battery time required.

Now let’s look at our battery: the Eclipse battery lasts 2.3 hours at 2 LPM continuous flow so we will need 3 batteries (2.3 x 3 = 6.9).

Note: If the flow setting is 2 pulse, then the battery lasts 4.4 hours and only 2 batteries would be needed (4.4 x 2 = 8.8).

Additional Points to Consider

  • While you may need oxygen only for a short time during your flight, airlines hold to a worst case scenario and assume that you will need oxygen during the entire flight, and they will not allow you to fly without sufficient battery power.
  • Short layovers between connecting flights will not allow enough time to recharge used batteries so you need to add this additional time into your calculations.
  • Be sure to use your DC power supply while driving to the airport so you do not prematurely drain your batteries. Also, as soon as you get through security, use the electrical charging station at the gate (or a plug on a wall) to keep your battery charged while waiting to board the airplane.
  • Battery duration times provided by the manufacturers assume a new battery. As your batteries wear down over time you may need an additional battery to have sufficient battery power for your flight.
Tips for Buying a Used Portable Oxygen Concentrator

While the cost of purchasing a portable oxygen concentrator has come down over the past five years, it is still a big investment and often beyond the financial reach of those who need a portable unit. Purchasing a used portable concentrator can be an economical option and not terribly risky if you do your homework.

As with the purchase of any portable oxygen concentrator, the most important decision is determining which one is best for you. My series on choosing the best portable concentrator is a great place to start to help you think through the choices you must make when choosing a portable oxygen concentrator. In additional to oxygen output, size and weight, battery power and sound level, it is also veryimportant to consider the warranty and service you will receive from the dealer.

The Warranty Is King

When purchasing a used portable oxygen concentrator the warranty can be a deal-maker or deal-breaker. While many tend to overlook the warranty on used concentrators, the warranty is essential and actually gives the unit its value. Without a warranty, an oxygen concentrator has very little value because the minimum cost to repair a portable concentrator is usually between $500 and $900 and manufacturer repairs include only a 90-day warranty. You may think you’re getting a bargain up front and then find that repair costs eat up the difference you saved and then some.

The Dealer Holds the Warranty Keys

Be aware that the warranty for a portable concentrator is issued to the original purchaser, which is the authorized dealer that purchased the unit from the manufacturer. When you are purchasing a used concentrator from an authorized dealer be sure to ask about the warranty that comes with the unit. You should receive a warranty of about one year and never settle for less than ninety days. Also ask if the warranty can be longer than one year. Since manufacturers issue a 3-year warranty on new units, there may be more than one year remaining on the unit you are purchasing. Reputable companies will gladly increase the warranty from one year to the length of the original warranty.

When you are purchasing a used concentrator from an individual then doing your homework is even more important. Ask the seller the model and serial number of the unit, as well as information on the dealer from which they purchased it. Then contact the dealer and ask them about the warranty for the unit for a second-hand purchase. I have found only one dealer, OxiMedical, who will transfer the warranty internally from their original customer to another person. Without this internal warranty transfer, the warranty on the unit is essentially lost because the manufacturer will not do a warranty repair unless the original authorized dealer makes the request. There are exceptions to this, but only reputable dealers are willing to go the extra mile.

Try Before You Buy

If purchasing a used portable concentrator from an individual, request to try the unit before committing to purchase. You’ll want to make sure it is capable of producing the oxygen you’ll need and whether it meets your mobility and travel needs. I recommend using a fingertip pulse oximeter to check to your blood oxygen levels while sitting and walking.

If you are purchasing from an authorized dealer, you will first have to complete the purchase, but you should receive a trial period during which you can exchange the unit or pay a minimum restocking fee. Again, use a fingertip pulse oximeter to give the unit a good test.

Also be sure to test the batteries. If the unit is more than two years old the batteries may charge to only 50-80% of the original capacity. Depending on the model of the unit, new replacement batteries will cost between $200 and $500 each, so be prepared to have an additional expense at the time of purchase or within a year or two of purchase.

With a little homework up front, you can enjoy the benefit of a portable oxygen concentrator without paying full price. Enjoy!
