The air purifier was shipped quickly. I opened box and it has a slight minty smell which I actually enjoy.  I have run the purifier and it works good but better in a smaller area versus a larger room.  I love the fact that it has multiple settings and a LOCK so my grandson cant play with it.  Also it has an led light with 2 settings that works as a nightlight too.   I recommend this.  I havent ordered replacement filters but its working great so far.
