31 Portable Air Filtration Systems

As technology becomes smaller, more capable and pollution more prevalent, air filtration systems are taking steps outside of the home and onto the streets.

Air-purifying masks have been around for as long as there's been unclean air, but now there are other less cumbersome and more discreet ways to enjoy a breath of fresh air immediately around you, such as with a backpack, air-filtering fashion or with a mode of transportation like a bicycle or a car that actually reverses the dirtiness in the air rather than adding to it.

Less obvious designs disguise themselves as other extremely small accessories like brooches, watches, bracelets and phones, which empower consumers to do their own small part in making the world a better, cleaner place to live.
