Yes, those are the reasons you are selling a purifier, right? A user exchanges money for the purpose of being protected from those harmful byproducts?
Without that protection this so called “air purifier” is really identical to the enclosure fan.
@W_Jing, please respond to the points raised by @JonnieCache, as this is extremely serious. I’m not sure what SnapMaker’s marketing angle is on this purifier, but it’s not very persuasive right now. It appears to be 1) there are seriously harmful dust and vapor byproducts and 2) the purifier doesn’t do anything about them that the enclosure fan doesn’t already do when vented outside.
