Turned off after a week of light use and never turned back on. Blueair did offer a refund though so this review is purely about the product itself.

I bought the Blueair 511i max. It worked well for 2 days. After that, I could no longer power on the unit. I tried all of the steps that Blueair recommends on their website if the unit cannot be powered on. None of these steps worked. I returned the unit and bought another purifier from a different manufacturer.
