I did not really say much to a filter change. Because these things is a very good. It is rugged and easy to use. It holds up well and lasts so long as the manufacturer says, even in a household with pets. The size makes it easy to save. They are not cheap, but I did not buy them too often, and it is worthwhile for the amount of air they produce. Rating: 5 / 5

The filters of this machine work really well. The machine itself is quiet, and deoderizes a small room within minutes. Rating: 5 / 5
