<H2><b>Desktop HEPA Filter Unit, 8cm Fan, 4 HEPA Filters</b></H2> This is a Desktop HEPA filter unit based on an 8cm computer fan and 4 HEPA filters made for a RoboVac. It is intended to be powered by a USB power pack and be placed on the desk in front of a child or adult to provide filtering of the air in the immediate personal space. The intention is to provide some air filtering locally to remove as many air particles as possible, particularly Covid, before the air is further cleaned by a larger filter unit in the room or removed by other ventilation methods. The filter type used are these https://www.amazon.co.uk/gp/product/B07BMDWD3C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Keep an eye on the price, it can vary with these filters and there are probably a few different sellers on Ebay and Amazon. The fan I used is a standard 5V 8cm PC fan with a USB connector on it. There are plenty available on Ebay or Amazon or a general computer shop. See my Twitter profile for all the tests performed on these Desktop HEPA Filter Units and the different types of units designed. https://twitter.com/strawthatbroke I have provided the STL and the Freecad file. It's a single-piece print and I used Ultimaker Cura 4.12.1 for the slicing. <b>This is a not-for-profit venture.</b> I originally designed it because I wanted to do something to make children safer in schools that parents and children could be in control of. It would be great if people used it in any situation where personal air filtering made sense. Good luck
