Best praise vs top criticism for Levoit Core 600S
“I replaced all of my round Levoits with Coways and it has nothing to do with the whole hepa controversy. Levoits are good and work very well. It was due to maintenance. I won't buy an air purifier without a removable prefilter again. It makes maintenance so much easier. Especially with the 600s as it's big. Both are great units, but the 400s is much easier to clean.”
“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.”
