The filter has been working well in our 1000 sq/ft. I can see it adapting to the changing quality of the air (very evident when we cook), and it is surprisingly quiet in the lower settings and not bad at all on the turbo setting. We tried a Molekule for a while and their "turbo" setting was much louder. Considering the layout is not 100% open I think it is working really well. We have a 1 1/2 year old and the lock function is helpful. One thing I would have liked to see is the ability to lock it when the lights are off. With the lights off our toddler knows that by pressing somewhere it'll bring the lights back on and eventually ends up modifying the settings. So, it is either lights off or locked.
