I do love this air purifier. We keep it in our bedroom - we have 3 golden retrievers and one is a shedder. The air quality is definitely better as a result - less dust and dog hair, and the filter is easy to clean between changes. You can order replacement filters, we did a 3 pack for an OK price. We haven’t used the Bluetooth, but the fan settings and the air quality read outs are helpful and perfectly adequate for what we need. I may order another for our living room area - it seems to also reduce odors pretty well.
