For people with weakened immune systems—such as after transplant, chemotherapy, or during prolonged steroid use—simple environmental steps can help reduce exposure to airborne mold. These tips are not a substitute for medical guidance, but they can support the plan you make with your care team.
Indoor tips
- Air quality: Ask your team whether a portable HEPA purifier makes sense for your main living space or bedroom. Keep doors/windows closed on high-dust days.
- Moisture control: Fix leaks promptly; aim for indoor humidity 30–50% with ventilation or a dehumidifier.
- Filters: Change HVAC filters as recommended; consider higher MERV ratings if compatible with your system.
- Cleaning approach: Damp-dust and damp-mop (dry sweeping can aerosolize dust). Wear a mask if you’re sensitive to cleaning products or dust.
What to avoid (when possible)
- Renovations & demolition: Construction dust can carry spores. If unavoidable, seal off work areas and stay elsewhere during the messiest phases.
- Standing water & potted soil: Avoid handling houseplant soil or aquarium maintenance; ask someone else to help.
- Humidifiers without maintenance: If used, follow strict cleaning schedules to prevent mold growth.
Outdoor & travel
- Gardening/yardwork: Skip raking leaves, composting, mulching, or turning soil during high-risk periods. If exposure is unavoidable, talk to your team about masking and other precautions.
- Seasonal peaks: After storms, floods, or during heavy pollination seasons, reduce time in dusty outdoor areas and consider route changes away from demolition sites.
- Lodging choices: Pick accommodations with good ventilation and no visible water damage; request non-carpeted rooms if available.
Personal routines
- Masks: Your clinicians may recommend well-fitting masks (e.g., in dusty environments or during hospital visits). Follow their advice on type and timing.
- Showering & clothing: Shower after high-dust exposure; launder clothes that picked up dust or soil.
- Symptom diary: Track fevers, cough, sinus/facial pain, shortness of breath, and report changes promptly.
