Within 2 hours of turning on the unit my wife noticed a big difference! Our house is pretty clean just gets dusty in the rooms that we spend most of our time which was the reason for the purchase. We have not had the unit long enough to pass judgement on its ability to reduce dusting however we both are noticeably less congested. The only change I would like to see is an auto on mode instead of having to turn it on for different time settings.

So far, I love this air purifier. I keep it on the auto function & multiple different times it randomly bumps itself up to the middle to highest setting due to picking up some higher than optimal levels in the air. It’s super quiet on the lowest setting. It’s great! I’m buying more for the upstairs.

we’ve had the black whole home purifier for a little less than a month. for one we love the look of it. its hard to tell if there’s really been any difference so far, but we like to think that it helps! the fan will kick on to medium or high if we are cooking in the kitchen, or if i’m smoking my vape nearby. so it for sure does sense when there’s things in the air. but other wise it just runs in chill mode lol. when i change the filter after 3 months that’ll show what it’s really pulling out the air! but anyways, it does give us a piece of mind.
