• ENERGY STAR recommends purchasing an air purifier that has a clean air delivery rate (CADR) at least 2/3 the size of the room. This allows the air purifier to clean the entirety of the room's air approximately 5-times in one hour. The Levoit 600s has a CADR of 377 cubic feet per minute, making it ideal for extra large rooms roughly 565 sq ft. 
• The Levoit 600s utilizes a replaceable 3-in-1 air filter:
  1. Nylon pre-filter to capture larger particles in the air like pet fur, dust and lint. 
  2. HEPA filter to capture particles as smaller particles (down to 0.3 microns) like smoke, mold spores, pet dander, pollen and other allergens. 
  3. Activated carbon filter to reduce the presence of volatile organic compounds (VOCs) and odors. 
• The Levoit 600s is Wi-Fi enabled, allowing you to operate it using smart phone with the VeSync app or via Amazon Alexa and Google Assistant. 
• Be alerted when it's coming time to replace your filter through the replacement light indicator on top of the unit. 
• The Levoit 600s displays your room's indoor air quality on top of the unit. You can also view particulate matter updates in real-time through the VeSync app. 
• Set a timer in 2, 4 or 8 hour intervals at the unit or create a routine schedule in the VeSync app to have it turn off automatically to save even more energy. The 600s also has an auto setting powered by AirSight Plus, a smart laser dust sensor inside the air purifier that adjusts fan speed automatically based on air quality.
