Now it's time to integrate a HEPA room air cleaner. These devices are especially beneficial in homes with indoor pets, or with children who have allergies. If people in your home are allergic to pet dander or dust, a HEPA Type filter is sufficient. However, if pollen, mold and other allergens are a concern as well, it's best to invest in a True HEPA air purifier. For example, the True HEPA Allergen Remover can trap a variety of different potentially harmful particles. Better yet, you can breathe easy knowing that the carbon odor filter contains Arm & Hammer baking soda, which fights unpleasant smells from pets, trash, litter boxes, cigarette smoke and cooking.
