What is one way to reduce allergens associated with pets?

Brushing and grooming the pet is an effective way to reduce allergens. This process helps to remove loose hair, dander, and other debris from the animal's coat. Regular grooming can prevent the buildup of allergens in the home environment by capturing them before they have a chance to spread. It also allows for the collection and disposal of allergens that would otherwise be shed into the living space, leading to a cleaner environment.

The other options may have certain benefits but don't address the core issue as effectively. Letting pets outside might provide temporary relief from allergens in the home, but it doesn't eliminate the allergens that are already present indoors. Feeding pets outside helps in minimizing food-related allergens but does not address dander or fur. Using air fresheners can mask odors but does not effectively reduce any pet-related allergens in the air or environment. Thus, grooming is the most direct and beneficial method to mitigate allergens associated with pets.
