Though invisible itself, the air we breathe is a microcosm of identifiable pollen, fungal spores, viruses, dust particles, and fine particles of human pollution from everything from cars to asphalt sidewalks. It’s not something we should obsess over day to day, but as more people measure air quality on their own, many are getting readings they’d prefer to address. However, not everyone wants to buy an air purifier, which can cost several hundred dollars.
