Why Air Purifiers & Humidifiers are Great for Back-to-School Season

Are lower test scores something you can breathe in? In 2016, a controlled study examined the role air quality plays in our daily cognitive functioning. They set up two offices—a “Green” building with low airborne pollution levels and a “Conventional” building with higher airborne pollution levels. During six full workdays, they studied the effects different concentrations of volatile organic compounds (VOCs), carbon dioxide, and general ventilation had on workers’ cognitive scores.  


The conclusion found that the Green building workers scored up to 101% higher than the Conventional building workers, shocking everyone with the dramatic impact clean air can have on focus and cognitive clarity. 


So how can airborne pollution affect our cognitive clarity? Consistently bad air quality can trigger allergy symptoms, distracting us with congestion, coughing, and itchy skin. It can even lead to increased neuroinflammation, which can impact our mood and motivation levels.  


Whether you're setting up your dorm room or creating an at-home study space, it’s important to prep your environment for success. One of the easiest ways to keep your space fresh is with our favorite duo: an air purifier and humidifier. An air purifier removes unwanted airborne contaminants, while a humidifier puts moisture back into your air, helping to reduce congestion and cold symptoms.
