Portable Oxygen Machine High Purity 1-7L/min Oxygen Flow, 35%-90% Adjustable, DIDIYY 2-in-1 Intelligent Oxygen Device with Timing Function and Wireless Remote Control - Perfect for Home and Travel

We have regular visits from the family member of ours that needs to be able to breathe purified oxygen all of the time and rather than them having to lug around tanks all the time it made sense for us to have a portable oxygen machine that she can have moved around the house to go wherever she needs to be.It works exactly as it should by basically purifying the oxygen and pumping it through the tubes that are connected to the portable oxygen machine this allows you to breathe in purified making it a lot easier to breathe. For anybody who actually has a direct need for one of these you'll know exactly how it works and this one is no different to the machines that you would be provided for on a temporary basis from medical supplies.It does come with its own little tool remote which means that you're not crouching down trying to find the buttons on the machine itself and it can be controlled without virtually any effort.Overall it's been a great addition to allow our family member to feel a lot more comfortable at home.
