[Home Tips] How often should you clean dust-accumulated fan blades?

🕵️♀️ Editor's observation: Why are fan blades in Hong Kong so prone to dust accumulation?

Hong Kong's humid weather and high levels of dust and fiber in the air, combined with static electricity generated when fans are running, make it easier for dust, hair, and dander to adhere to the blades and grilles. Common causes include:

1. Open windows for ventilation for a long time
   • Street dust and car exhaust easily enter the room and stick to fan blades.
2. Indoor activities generate fine dust🧹
   • Sweeping the floor, cooking, pet hair loss, etc. will increase the number of particles in the air.
3. Electrostatic adsorption effect ⚡
   • When the fan blades rotate at high speed, they become charged and attract dust particles.
4. Humidity makes dust stickier🌧
   • Humidity causes dust to clump together, making it harder to blow away.

⚠️ Editor's reminder: Health and usage issues of dust-accumulated fans

• Blow out dirty air😷 : Dust, dust mite feces, and pollen are blown away, affecting respiratory health.
• Aggravates nasal allergies and asthma : Long-term inhalation of allergens will worsen symptoms.
• Reduce air supply efficiency💨 : Dust increases wind resistance and weakens wind force.
• Increased power consumption and noise : The burden on the motor increases and the operating noise becomes louder.

🛠 Editor's suggestion: How often is it best to clean it?

Based on Hong Kong's climate and home environment, the editor recommends:

• Frequent daily use (≥6 hours per day) → Clean every 2-3 weeks
• Less frequent use (1-2 times a week) → Clean once every 1-2 months
• Have pets/live close to the road → Clean every 1-2 weeks

💡Special tips : In summer, when it is used frequently, the cleaning frequency should be increased; in winter, it should be cleaned thoroughly before being put away.

2. Use screens or dust nets when opening windows : reduce external dust.
3. Spray anti-static spray on the blades⚡ : reduce the adhesion of dust particles.
4. Put on the dust cover when not in use : prevent dust accumulation.

📝 Editor's Summary

Due to Hong Kong's humidity and air quality, dust accumulation on fan blades is inevitable. However, as long as:

1. Clean regularly based on frequency of use (2-3 weeks or less)
2. Remove and clean the blades and mesh to ensure fresh air
3. Cooperate with dust prevention measures to extend the cleaning cycle
