Doomsday Preppers: Budget Prep: Air Filter
You can build your own air filtration system using only inexpensive parts from the hardware store.
The good news is that progress is happening all on it's own, with solar prices falling by half every 3-4 years. All we have to do is wait; all the hollering in the world won't change the outcome either way by enough to matter.

Consumer Reports says there are things you can do that can be more effective than an air purifier. First, ban indoor smoking."If you've got a smoker in your family, you should not let them smoke in your house because that's an incredibly large source of pollution in the home," . It seems like everywhere I go, people have an air purifier running. No one wants to breathe dirty air. Just remember a machine alone, won't clean the air or relieve asthma or allergy symptoms.
