Which home modification is best to reduce asthma triggers in the home?

• A. Use a humidifier in your child's room.
• B. Have your carpet cleaned chemically once a month.
• C. Wash household pets weekly.
• D. Avoid purchasing upholstered furniture.

Answer: (D)

Reducing exposure to indoor allergens is a key way to lower asthma triggers at home. Upholstered furniture creates large, soft surfaces that easily trap dust mites, their waste, pet dander, and other particles. These allergens are released into the air with daily use and can persist, continually triggering symptoms in children with asthma. Among the options, avoiding upholstered furniture removes a major and persistent reservoir of allergens, delivering a stronger, longer-lasting reduction in triggers than the other choices.

Humidifiers can backfire if humidity becomes too high, promoting mold growth and dust mites; carpet cleaning with chemicals can introduce irritants and doesn’t eliminate the embedded allergens as effectively as removing the main reservoir. Washing pets weekly helps but only addresses part of the allergen load. If removing furniture isn’t possible, consider hard-surface furniture, allergen-proof covers, frequent high-efficiency vacuuming, and maintaining low indoor humidity to further reduce triggers.
