    Consumer Reports rates the filtering as fair, but I've seen it visibly work well. The allergy sensor is great - the room is carpeted & when the dust from the carpet triggers the allergy sensor, it's time to vacuum. I can also see when other activities cause the number of allergens to increase - the fan noise level is perfect because you can only hear the fan when there are too many allergens in the air, which grabs your attention so you can try to fix the situation. The device can be controlled by the app or by through your voice assistant, but everyone just sticks it on auto. I actually place my filter facing the wall because the air intake is on the back, BTW. Regular price is high, though - bought this 1 year ago as Deal of the Day. Amazon is good for replacement filters.
