What Redditors Say

Best praise vs top criticism for Levoit Vital 100S

Best Praise
+5 pts
β€œGlad you’re happy with the switch. The vital is in fact a much better unit. Now do yourself a favor and turn off auto mode. Your air isn’t getting clean with auto.”
r/AirPurifiers

Top Criticism
+2 pts
β€œIs your ceiling 2.4 meters high? If so, this would make your rooms' volume 96 m^(3). The particulate Clean Air Delivery Rate (CADR) for a purifier should be (bare minimum) 3 times your room's volume when measured in m^(3). This is for normal pollution concentrations. The Levoit Vital 100S has a CADR of 240 m^(3)/h. However, you need a CADR of 288 m^(3)/h at the very least. I would recommend something more powerful, with a CADR ranging from 384 - 576 m^(3)/h. Regarding your bathroom, is it closed off from your bedroom? Air purifiers can't overcome walls and doors. Don't use Auto Mode. The sensor responsible for detecting pollutant changes is very cheap and inaccurate. You should only be using the highest airflow/speed setting possible for now. Ideally, you should buy a different purifier with a higher CADR.”
