The last while, every time we turn on the TV or read a newspaper, even talk to friends, we're hearing about the poor quality of our air. I've seen ads on TV about HEPA filters, and wondered what exactly they are. I was just at a site for air purifier/air cleaner systems, and found out this:
HEPA Air Cleaner - This is a particular type of filter called HEPA, which basically means ones that are designed to remove the vast majority of extremely small particles out of the air. They're very efficient, but they can be costly to replace. I also thought this was interesting: Car Air Purifiers - These are little portable versions, which you usually plug into the car's cigarette lighter.
