I have suffered with congestion and allergies for as long as I can remember... I am basically a big allergy ridden human! I thought that the purifier could potentially help me in my quest to find some sort of relief overnight. I came across the purifiers by chance and read reviews and saw that air purifiers were actually helping other people with their allergies; so I thought that I should give this a go. After all, if they work on other allergy ridden people, then why wouldn't they work on me! Well, I have to say that immediately I found some relief! I was suffering every night with itchy eyes, sneezing and restless sleep - but the purifier has definitely helped me! I wouldn't say my allergies have disappeared altogether (I mean I can't expect a miracle!!), however, I would most definitely state that I seem to be suffering at least a 50% reduction in symptoms! To me, this is a miracle! I am extremely happy with my purchase to say the least! I also love that I can monitor the air quality in my room whenever I want to, all from an app on my phone! Ingenious!

Quiet operation up to high fan speed.
