I didn't know a word about the product spec... 

and this is the first air purifier coming to my home.

Very user-friendly and ready to use, 

just unwrapped the packing of the filters and put it back and off you go. But the filters inside are a concern, need to be replaced from time to time, one active carbon filter I just check the price is costing around 200HKD. Bup.

Seriously,

the colour indicator went red-lighted at the moment I turned it on,

(indicating the air quality was bad....?
But I did have a hotpot party last night,, the smell didn't go away)

and then the light turned into purple in 5 minutes,

into blue in the later 10 minutes.

....wow seems you're doing good.

welcome to my place.
