Mechanical Dust Removal Equipment (e.g., centrifugal fans)
- Cleaning Steps: After powering off, remove the blades and use a soft brush to remove surface dust. Stubborn oil stains can be wiped with a neutral detergent.
- Frequency: Clean every 2 months; in high-temperature environments, this should be shortened to 1 month.
Electrostatic Dust Removal Equipment (e.g., electronic air purifiers)
- Core Maintenance: The dust collection plate should be wiped with alcohol wipes to avoid washing with water, which could cause a short circuit.
- Data Support: The California Air Resources Board recommends cleaning weekly to maintain over 95% dust removal efficiency.
Filtration-Based Dust Removal Equipment (e.g., HEPA filter purifiers)
- Replacement Cycle: In typical household settings, HEPA filters should be replaced every 3-6 months (3M manufacturer's experimental data); in pet-filled households or high-pollution areas, this should be shortened to 2-4 months.
- Cleaning Tips: Some filter models are washable, but must be thoroughly dried for at least 24 hours, otherwise mold may grow.
