Originally, I had InqVent at just below $30. During building the parts list page, I discovered a couple of the pieces had gone off sale and some had increased significantly since the pandemic started. Also, all the little bits and pieces that just come out of my parts bins were not really accounted for. And as you will note, many of the purchases are for multiple parts. If you just make one, you’ll be closer to $100. But…
… as a quick search on the Internet will disclose: “Costs for these ventilators can range from $5,000 to $50,000.“
