Sorry, there was a problem. Please try again later.The filter will need to be changed 4 times per year, depending on the conditions in your home. IF lots of pet dander and dusty environment expect it to be every 2 months. Depending on your model there should be a RED icon that comes on when the filter is needing replacement.

Please take a look at the white sheet to see if it has turned gray or black, and the more dirt on that sheet, the more likely it is that your filter needs changing.
