This is my simple design for a small air filter quiet enough for my nightstand. Small enough to be tabletop but large enough to be useful.
It uses four “Germ Guardian” size B filters. These can be found on Amazon inexpensively, I paid $22 for four. The fan is an “AC Infinity” low speed LS1238 120mm x38mm “muffin” fan.
Besides the fan and the filters, you'll also need 4x M4 heat set inserts and 4x M4 45mm bolts.
Total cost right around $40
