How do I wash the back (black) charcoal filter of XL-15 living air classic air purifier or the BreezeAT living air purifier?
For model #s: XL-15C and XL-15S and all BreezeAT air purifiers, the back filter should be cleaned once every 30 days. The charcoal metal frame filter is washable and could be washed once every 30 days. However, just like with the newer back carbon filter for newer models, it could be hand-vacuumed once a month or dusted with compressed air, and then washed once every 90 days depending on the amount of pollution where the unit is placed.
