Which of the following options is NOT a method to reduce environmental triggers for asthma?

Using a feather duster to dust all surfaces is not an effective method to reduce environmental triggers for asthma. Feather dusters can actually disturb dust and allergens, causing them to become airborne and potentially inhaled, which could worsen asthma symptoms. Effective dusting methods would involve using damp cloths or electrostatic dusters that trap dust instead of sending it back into the air.

In contrast, keeping pets out of the bedroom helps minimize exposure to pet dander, a common asthma trigger. Installing air purifiers can significantly reduce allergens in the air, improving indoor air quality. Regularly washing bedding in hot water helps remove dust mites and other allergens that can accumulate in linens, further alleviating asthma symptoms. Each of these methods contributes positively to creating a healthier environment for those affected by asthma.
