Business Profilefor1st Class Medical LLC

I purchased a Arya Airtivo *** in May 2024 for $2000 plus $45 shipping. I needed a Portable Oxygen Concentrator (***) for daily use when out of the house and away from my larger home concentrator.I received the unit just before we left on vacation and I was excited to finally be able to take walks with my wife and to attend public events, etc. As soon as I charged and turned on the *** I heard loud clicking and popping sounds. I did use the *** for walks outside, etc. but the loud pops made it impossible to use in public settings.I contacted 1st Class Medical ************* and was told to return the unit for replacement. I paid the $90 for shipping. I received the replacement and againas soon as I turned it on I heard the same identical popping sounds.I again contacted ************* and I was informed that the popping sounds are normal operation. After days of research I realized that this is not true. Only a few owners of this same unit even mentioned popping sounds. Most said that it is extremely quiet.I told ************* about this and again was told that the popping sounds are normal operation. Even more importantly, I have noticed that the unit is not producing sufficient oxygen. The unit did not give me the relief I expected. My research indicated that the popping sounds are the compressor and that it might not be producing oxygen correctly.************* again disregarded my concerns. The bottom line is that I have now paid $2135 for a *** that I can not use in public and does not provide me with adequate relief. No one at 1st Class Medical seems to care. They have their money..thats all that is important.
