This is a clean filter for the BRUNO CALM MIST humidifier that I had in stock. I took it out of the box for the photos, but the plastic wrap is unopened. The humidifier broke last season, so I'm selling this as it's unused. The third photo is a reference photo of the main unit. This is a sale of the filter only. - Brand: BRUNO - Product Name: CALM MIST Clean Filter - Application: Humidifier Filter
