Do the filters in the Blueair Pure 411 require regular replacement? If so, how often?

According to the product experts' reviews, the filters in the Blueair Pure 411 do require regular replacement.

You can wait for a red light to let you know that the filter needs replacement, or you can replace it after 6 to 8 months, which is a recommended time for replacement. - Blueair states that the filters must be replaced after six months of continuous use. If you only use your purifier at home, you can expect these filters to last as long as a year.
