Why Cleaning Your Dyson Filter Matters
Dyson vacuums are designed with advanced filtration systems that capture fine dust and allergens. Over time, these filters collect dirt, hair, and microscopic particles. If you neglect to clean them, problems can occur:
- Reduced Suction Power – Dust buildup blocks airflow.
- Strain on Motor – A clogged filter makes the motor work harder.
- Shorter Battery Life – Efficiency decreases when suction is weak.
- Poor Air Quality – Dust may escape back into your living space.

- High-use households (pets, children, carpets) → Clean every 2–3 weeks.
