The Asthma and Allergy Foundation (AAFA) offers some allergy-friendly cleaning tips:  -- Open windows and run fans while you clean. -- Use a damp cloth to remove dust or a cloth that traps dust. Dry dusting can spread allergens around the house. -- Use a vacuum with a HEPA filter. Watch air flow, since some vacuums can push allergens back into the room. -- Take a shower and change clothes after cleaning. If you wear glasses, clean them, too. -- Reduce clutter  If you’re severely asthmatic, always check with your doctor about how to safely handle cleaning chores.
