How do air purifiers work?

Check it out! This machine is like a SUPER-powered vacuum for the air in your room. First, the messy stuff like dust and itchy pet hair gets pulled into the bottom. We call that DIRTY AIR! Next, a spinny FAN gulps it all up and pushes it forward with a big WHOOSH. Then, the air hits the OUTER FILTER. This looks like a green fence that catches big pieces of dust before they can get deeper inside. But look close! There is a purple HEPA FILTER with teeny-tiny holes that are so small they can even TRAP invisible germs. It is like an obstacle course that only air can win! Finally, out comes the CLEAN AIR! It is fresh, sparkly, and ready for you to breathe in. Whew! What a ride! Tiny Concepts.
