@TopherSpiro You mean stay home with other people? This can be done, and there is a ton of study on this (if you consider the virus in the air a chemical). This is known as negative pressure and here is how you can do it at home.

1) Place the person in a room that has access to ...
@TopherSpiro ... an external window that will not blow back into the house. The room also has to have no other outlets (IE block any AC returns or bath vents in the room if they tie into anywhere else in the house).

2) use a hallway as an airlock if the house can be done that way...
@TopherSpiro 3) place a fan blowing out the window so it is pulling air from the rest of the house, through the room, and then out the window. A scroll fan or another that can build pressure is best. .001psi is enough most of the time...
@TopherSpiro 4) in the doorway hang a sheet or something else that causes a restriction. That way when the door is opened (slowly only) the restriction prevents momentary air movement from overpowering the constant flow from the fan...
@TopherSpiro This is the opposite of purged and pressurized as used in the oil industry or the same as a negative pressure room used in chemical or medicine studies. Hope this helps.
@TopherSpiro I have been asked to write this up with some diagrams. I will make a new thread and drop a link here for anyone finding/following this.

Give me just a few hours to wrap up my current one and I'll get that done for everyone.
