On the blue Everflo concentrators they have; Q which stands for quiet, it has more insulation and a muffler exhaust cover. The OPI stands for Oxygen Percentage Indicator, it will alarm if the oxygen is low.

@@DependableOxygenCompany Sorry for not being fully clear on my first message. I already knew what those letters meant. But Thanks for the answer. What I want to know is if the Philips respironics everflo I ordered here in Brazil will also have those Q and OPI features.

Zé da Silva you have to ask for those features when you order. So if you did t they probably won’t be included as they are an upgrade and cost more money.

@@DependableOxygenCompany Very true. I didin't knew at the time about the existence of those features. Thanks for the answer. Do you know if it's possible to upgrade one machine that does not come with it from the store?

Yes it will work up to 2 liters per min. 10 pound package. Let us know if you have any other questions.

Can this be used in planes(will it make a difference?) and on mountains? Also, if I purchase from your website, in how much time will it ship to New Delhi India?

Shekhar Malhotra we cant ship out of the United States per our agreement with the manufacturer. Check here for a distributor in India. www.philips.co.in/healthcare/solutions/sleep-and-respiratory-care

Sounds like the on off switch is not working. You need a new board. Contact the dealer you got it from to get it repaired. Or just remove and insert the battery to turn on and off.

Mandar, yes it can be used for COPD patients. The simply go can make 2 lpm continuous and 1-6 pulse.

@@DependableOxygenCompany sir can we rely on the pulse mode? is it dependable?

Yes you can plug the machine in the wall and charge it without it running. It will charge in the car-DC or home AC by simply plugging it in.

3 hours on a pulse of 2, and 1 hour with continuous flow of 2.

tom2 jones...I’m not sure of you’re question. It’s not clear. The filter on the simply go? There is not an external filter. It has an Internal filter but it only serviced by authorized dealers like me, or Respironics service centers.

Johnny Gonzales where do you live?

@@DependableOxygenCompany Deming New Mexico

Johnny Gonzales it depends on the supplier if they will provide a 2,000 dollar plus machine for the 18-30 dollars a month rental. Insurances and Medicare don’t pay enough to make it worth while. But ask around some of them will. Most are just buying them if they want them. Talk to you’re congressman to increase the rental on oxygen. It’s been cut 60 percent the last 10 years.

@@DependableOxygenCompany thank you sir

herman herman get it to a certified dealer. The low o2 can most likely be caused by the molecular filter called sieve beds are bad. They filter the nitrogen out. These can be easily be replaced. Cost are usually about $200 for parts and labor if not under warranty. I sell most of mine with 5 year warranty. So check with dealer to see if it’s under warranty. Standard warranty is 2 years.
