Many modern apartment buildings and dorms feature central cooling and heating systems, said John McKeon, CEO of Allergy Standards, a global organization that certifies safer products for people with asthma or allergies. This means residents don’t have much, if any, control over the air pumped through their vents or knowledge of where it’s coming from. McKeon said that, in these situations, people also don’t have control over how often filters are changed or ducts are cleaned, which means the air that arrives in their small space could be polluted, dry, humid or stale.
There are many products you can use to monitor and improve air quality in your small space. But before you buy, McKeon said, it’s important to decide what you need. Are you looking to filter pollutants out of the air or increase air circulation? That may mean you need an air purifier or fan. Or is your air too dry or too humid? That may call for a humidifier or dehumidifier.
