Thanks so much to Conair for giving me this medium air purifier for free to review. 
I was so excited to receive it, as I'm allergic to my cat, and I also have some other airborne allergies. 
The air purifier is whisper quiet while operating, and not noisy whatsoever. 
It has tiny lights on it for the different levels, but the lights themselves are not bright at all so they aren't bothersome. 
I had never previously owned an air purifier so I was sceptic at first if this product might really help. 
Well, after only 2 days my sneezing had stopped, and I swear the air even smelled cleaner! I'd definitely like one for another area in my house as well! 
I highly recommend this Conair medium air purifier to anyone looking to clean their air around them.
