Harmattan Dust: How to Keep Your Lagos Home Clean (2026 Guide)

By the Summitrise Cleaning Services team · Last updated 2 November 2026 · 7 min read

Every year the harmattan wind carries fine Sahara dust south across Nigeria, and even coastal Lagos gets weeks of haze, dry air and a grey film on every surface. The dust settles on furniture within hours, clogs AC filters, coats window nets and gets into sofas and rugs. For anyone with asthma or allergies it is more than a nuisance. This guide explains how to keep your Lagos home clean through harmattan, with a simple cleaning schedule you can follow.

What is harmattan, and when does it reach Lagos?

Harmattan is the dry, dusty north-easterly wind that blows from the Sahara across West Africa during the dry season. Across Nigeria it typically runs from about November to March, and on the coast its strongest dusty spells usually come between December and February. Lagos often gets a milder version than the north, but the dust haze can still reduce visibility and coat homes for days at a time. The Nigerian Meteorological Agency (NiMet) publishes dust-haze forecasts, which are worth checking before you plan a big clean.

Why harmattan dust is so hard to keep out

• The particles are very fine. They pass through mosquito nets and gaps around doors and windows.
• The air is dry. Without moisture, dust stays airborne longer and resettles after cleaning.
• Static builds up on screens, plastics and glass, which hold dust.
• Lagos adds its own dust from traffic, construction and unpaved roads, so the two combine.

10 tips to keep your Lagos home clean during harmattan

1. Close up on hazy days. Keep windows and doors shut during dusty spells. Ventilate when the haze clears or after rain.
2. Dust damp, not dry. A slightly damp microfibre cloth traps dust. Dry dusters and feather dusters push it into the air, and it settles again.
3. Work top to bottom. Start with ceiling fans, light fittings, curtain rails and shelves. Finish with skirting boards and floors.
4. Mop, don't just sweep. Sweeping lifts fine dust. Mop tiles and marble daily in busy rooms, and use a vacuum with a good filter on rugs.
5. Put doormats at every entrance and encourage a shoes-off rule indoors.
6. Clean AC filters every two weeks. Clogged filters reduce cooling, raise electricity bills and blow dust around the room.
7. Wash window nets and clean tracks. Mosquito nets, burglary-proof bars and sliding-window tracks collect the most dust. Wash nets monthly.
8. Vacuum fabrics weekly. Sofas, cushions, mattresses, curtains and rugs trap dust deep in the fibres.
9. Cover what you don't use. Cover spare-room furniture, stored items, water containers and electronics when not in use.
10. Add some moisture. A humidifier or a damp towel in the room helps dust settle and eases dry throats and skin.

Protect your family's health indoors

Doctors in Nigeria warn that harmattan dust and dry, cold air can trigger asthma, allergies and other respiratory problems, and cause dry skin and dehydration (Humangle; AUN Health Center). A cleaner home helps, alongside simple habits:

• Keep inhalers and allergy medicine within reach for anyone with asthma.
• Wear a face mask outdoors on very dusty days.
• Drink plenty of water and moisturise skin and lips.
• Change pillowcases and bed sheets more often.
• Keep bedrooms especially dust-free: they matter most for sleep and breathing.

If someone has persistent breathing problems, see a doctor. Cleaning reduces dust but is not a medical treatment.

When to call professional cleaners

Regular cleaning keeps harmattan dust under control, but some jobs are faster and more thorough with professional equipment:

• Before Christmas: a full deep clean that covers ceiling fans, light fittings, cabinets and behind furniture.
• Sofas, rugs and mattresses: extraction cleaning removes dust that vacuums can't reach.
• Windows, nets and burglary-proof bars: our window cleaning service covers glass, frames and tracks.
• Short-let apartments: extra turnover cleaning keeps reviews high during the busy festive season.
• Offices and showrooms: increase the frequency of your office cleaning contract during harmattan.
• After harmattan: a seasonal deep clean in February or March resets your home.

Summitrise serves homes and businesses across Lagos, from Lekki and Ikoyi to Surulere, Ikeja and Magodo. Wondering what a deep clean costs? See our Lagos cleaning price guide.
