Best praise vs top criticism for Levoit Core 600S

Best Praise
+11 pts
“You can also read that the "scandal" was fueled by a competitor of theirs. Levoit 600s and the newer Vital 200s are well-regarded and well-reviewed units. Watch the videos by AirPurifierFirst on Youtube, and do a search to read what others here have to say on these units. I have Levoit units and especially like the Vital 200s.”

Top Criticism
+7 pts
“I have two barely used 600S that emit obnoxious foul smelling odor and fill the room with VOCs. Complete waste of money and we purchased extra filters too. Please update if you ever get anywhere. This is starting to seem like a widespread problem they're ignoring from what I've seen lately here.”
