You MUST remove plastic bag from filter-which is inside the machine
Only had it for one day!  However- it does NOT smell at all.  It is nice and quiet.  I dont know if it is doing its job of purification yet.  But only time will tell.  Other reviews speak of bad smell , but mine did not smell at all.  If you open package and just plug in - you will be in trouble- the filter inside the machine has a plastic bag over it- it MUST be removed before use!  I would not have known that, except i do read the manual.  I will try to update as we use it.<br />UPDATE June 14,2022-:  i have had the purifier for almost a week.  Have been through several boxes of kleenex.  Our allergies seem 100% worse….  Sneezing and blowing our noses!  I have the purifier going steady, so i do not know why it would make things worse. Maybe it has nothing to do with the purifier, but that would be a coincidence.  I havent given up on the purifier- just giving an update.  I will update again in a week or so.
