For people living with asthma, dust-mite allergies, pet dander allergies, or mould sensitivity, everyday cleaning can accidentally worsen symptoms. Activities like dusting, vacuuming, or using strong cleaners can stir particles and irritants into the air, triggering coughing, wheezing, or breathlessness. This guide focuses on cleaning-with-care strategies that make the home safer for asthma and allergy-prone individuals.

1. Declutter and dust strategically: Reduce clutter and use damp microfibre cloths to trap dust instead of pushing it around.

Why: Cluttered areas collect dust, dust mites, and dander—major triggers for dust-mite allergic asthma and perennial allergic rhinitis. AAFA (Asthma and Allergy Foundation of America) notes that dust build-up increases indoor allergen levels. Damp-dusting reduces airborne particle release, making it safer than dry dusting.

2. Choose low-fume, fragrance-free cleaning products: Opt for unscented, non-aerosol, low-VOC cleaners.

Why: Scented cleaners release VOCs that irritate sensitive airways, especially in irritant-triggered or non-allergic asthma. The European Community Respiratory Health Survey (2010) found that frequent use of cleaning sprays increased asthma risk almost as much as smoking several cigarettes daily.

3. Wash bedding, curtains, and soft furnishings in hot water: Wash weekly at ≥54°C and use allergen-proof mattress and pillow covers.

Why: Bedding is the primary habitat for dust mites—one of the strongest triggers for allergic asthma. AAAAI recommends hot-water washing and allergen-resistant covers to effectively reduce dust-mite allergen load.

4. Vacuum with a true HEPA filter or switch to smooth flooring: Use a vacuum with a certified HEPA filter or replace carpets with wood/tile flooring.

Why: Carpet fibres trap microscopic allergens that become airborne during cleaning. Smooth floors reduce allergen load, but phenyl-based cleaners commonly used on Indian floors can emit VOCs that worsen asthma by triggering cough and wheezing. A HEPA-filter vacuum and low-VOC cleaners help reduce both particulate and chemical triggers.

5. Control indoor humidity and inspect for mould growth: Maintain humidity between 30–50%, fix leaks immediately, and clean damp corners.

Why: High humidity promotes mould spores and dust-mite growth—potent asthma triggers. ACAAI highlights humidity control as a core part of effective indoor allergy management.

6. Clean or replace air filters regularly: Replace filters in ACs, purifiers, and ventilation systems every 1–3 months.

Why: Saturated filters recirculate trapped allergens into the air, increasing exposure to dust, mould particles, and dander. Regular filter replacement ensures cleaner airflow and reduces trigger exposure for asthma-prone individuals.

7. Reduce transfer of outdoor allergens inside the home: Leave shoes at the entrance, change clothes after stepping outside, and keep doors closed.

Why: Outdoor pollen, mould, and dust can trigger seasonal allergic asthma when carried indoors. ACAAI recommends reducing transfer pathways to minimise allergen exposure.

8. Avoid scented candles, incense, and air fresheners: Avoid all fragrance-based products and aerosol sprays.

Why: A 2015 study in *Environmental Chemistry Letters* found that incense smoke contains higher particulate levels than cigarette smoke. Everyday use of agarbatti or dhoop during rituals can irritate the airways and trigger asthma symptoms.

9. Keep inhalers nearby and track symptom patterns: Keep quick-relief medication accessible and note any cleaning-related flares.

Why: Environmental control helps reduce triggers but cannot replace medical supervision. Track symptoms and consult a specialist if flare-ups persist despite allergen control.
