+2 pts“Damn, I literally got the Airmega 250s yesterday from Amazon and found this exact issue with the fan. I am also debating whether to return it or not (Amazon does not offer to replace it for some reason, only return is possible and price went up today by like $100). In level 1 and 2 speed, all is fine, no vibration at all. Though at level 3, it does vibrate/shake slightly but nothing out of ordinary. I am a bit sensitive to noise so always run it at level 2 max I guess. Do your guys think it will really cause issues in the long-run? The warranty is 3 years. P.S. Just want to avoid the hassle of packing everything up again and maybe get a replacement that has the same issue :/”

Best praise vs top criticism for IQAir GC MultiGas
Best Praise
+9 pts“Is 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.”
