Drum like design with cylinder filter...kinda like the Mi Air Purifier. Wondering how effective it is against other brands like Sharp and also the noise level.

Looks like there's not much info about the filter, whether it's HEPA or not. Would you know?

This is based on my personal experience of using Mi Purifier 2S. I won't be surprised that there are better brands/models out there, but I think for the price and function of the Mi Purifier, it should do a decent-enough work:

- Can feel the difference in terms of air quality after turning on (I use Manual mode for maximum fan speed in the living room, a bit noisy but bearable)
- Some online articles criticised the the purifier's particle sensor is not sensitive enough and doesn't exceed 50 and above. I have seen more than 200 reading with the recent haze
- the purifier's Auto mode is also criticised for not doing enough purification work and leave the air with high API reading, hence I use it on Manual mode most of the time
- the replacement filter is also fairly easy to get online (Shopee Mi MY official store available)
