I think most people reading this who want to protect themselves at home should instead focus on getting an oxygen concentrator and not a ventilator. These devices enrich the oxygen level in air and connect to a person through a cannula or face mask. They are pretty easy to use and safe, and can be purchased from eBay or Ali for around $300 to $400 shipped. Only problem is that shipping from China is slow now so it will likely take 2-3 weeks to arrive. But this is what most people would get at a hospital unless they are gravely ill and require intubation.
