The air inside your home might not be healthy even if it smells fresh. Some gases, such as radon and carbon monoxide, are colorless and odorless but can be harmful if inhaled. Most indoor air quality monitors will detect the levels of oxygen and carbon dioxide in the home, and many others will detect additional pollutants, including volatile organic compounds (VOCs) and airborne particulate matter. Still others feature temperature and humidity monitoring in addition. Today’s best air quality monitors pair comprehensive detection with usability features, such as WiFi capability and remote monitoring. Ahead, see our favorite picks among the many options available now.
