It is way quieter than the square coway units which i like in the bedroom, but i still hear a hissing noise. Puts out a lot less noise than my old honeywell and moves twice the air.

It's also effective at removing cooking odors. It senses when there's stuff in the air well and kicks in for high vg vapes. It does an amazing job in cleaing the air and bad odor in my new apartment.

Air quality indicator works fine. It is shockingly good at detecting issues with air quality. The sensor is very sensitive.

At high speed, the whole circle is lit up. It has a 12 hour timer, which we tend to turn ours on as we retire to bedrooms.

It is aesthetically good pretty. The tower design saves floor space and the unit is sleek and pleasing looking. It looks very stylish and takes little space since it's upright.

The brightness of the lights make it unsuitable for a bedroom. The only setting that's tolerable is the first setting.

The noise isn't particularly loud, however is intermittent, high pitch and intolerable. It's very high pitched and honestly hurts your hears.

There is some concern that this technology produces ozone, which is a health hazard.
