What Redditors Say
Best praise vs top criticism for Levoit Core 600S
Best Praise
+11 ptsβYou 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.β

ViewTop Criticism
+7 ptsβI 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.β

What Redditors Say
Best praise vs top criticism for IQAir GC MultiGas
Best Praise
+9 ptsβIs go with the IQAir Multi gas model. There are also "steel can" models from the likes of Austin Air, AirPura, AllerAir, etc and they carry models with 15lbs or more activated carbon. But while none of those brands produce what I would consider a "nice" looking air purifier, I think the IQAIR model at least looks softer and blends in better than the others. Also filter changes are much less involved as you won't need to break out the screw driver.β

+5 ptsβFor smoke the usual go-to is the Austin Healthmate or the more expensive IQAir GC MultiGas.β
