Very simple, intuitive design means it can be placed sensibly almost anywhere, and the filters are easy to assemble and disassemble

I highly recommend this filter

They operate the power, the speed (four), the Ionizer indicator, the Timer indicator (1, 4 and 8 hours), the Filter reset Indicator and the Filter reset button

Most of them come in white or beige colors, but this one is a very shiny black, similar to many flat screen TVs

When it lights up blue, which is standard - air quality is normal

I actually turn it up all the way at night, and the sound is soothing and pleasant (to me)
