Replacement for Bissell part 1608683 on the CrossWave wet-dry line. Wet-dry machines load their filters faster than dry vacuums, so keeping a spare on hand matters more here than anywhere else in this list.
Vacuum filters come in two types: washable (foam, felt) and disposable (HEPA paper). Washable filters should be rinsed monthly under cold water and air-dried completely for 24+ hours before reinstalling — a damp filter will damage the motor. Disposable HEPA filters cannot be washed and should be replaced every 6-12 months. For pet households, cut these intervals in half.
