An efficient vacuum cleaner filter traps fine particles without restricting airflow. This allows your vacuum cleaner to maintain optimum suction while capturing some of the harmful dust, pollens, pet dander and other allergens from your home.

Not only does an efficient filter enhance the performance of your vacuum cleaner, it can also protect it from premature wear. A good filter will keep ultra fine particles away from the motor, thus avoiding dirt and dust buildup that can cause overheating and motor strain.

This filter guide describes how a filter works, details types of filters, and provides information about selecting a filter and filter maintenance. A glossary of common terms and questions and answers from our filtration experts are also provided.
