We will use it as a replacement while the original one dries for a day. It is not indicated on the market, but the instructions for a similar Chinese filter in a well-known online store say that the filter should be washed once a month and it lasts for three months. The original one should also be washed once a month, but it lasts 2 years, according to the manufacturer. So I don't know how justified such savings. Time will show.
