Consider the manufacturer note that the original filter configuration is rated to clean up to 1000 sq ft under certain conditions, while the product listing references coverage up to 3500 sq ft, so check room layout and ventilation when estimating effective coverage. Filters should be changed according to the indicator and typical indoor conditions, and replacement intervals can vary with heavy dust or pet dander. 🏠
