One of the most effective ways to reduce allergens in your home is by vacuuming frequently. Vacuuming helps to significantly reduce dust mites, pet dander, and pollen from carpets, rugs, and upholstery (1). Use a vacuum with a high-efficiency particulate air (HEPA) filter to ensure that the allergens are not released back into the air.
Wash Bedding Regularly
Dust mites thrive in warm, humid environments, making your bed a prime location for them to breed. To reduce the number of dust mites in your bed, wash your bedding weekly in hot water above 130°F (54°C) to kill the mites (2). Use hypoallergenic bedding covers to prevent dust mites from entering your pillows and mattress.
Use Air Purifiers
Air purifiers are devices that remove pollutants from the air. They are particularly helpful in reducing allergens such as pet dander and pollen (3). Look for an air purifier with a HEPA filter, which can remove particles as small as 0.3 microns.
Clean Mold and Mildew
Clean any visible mold and mildew with a solution of bleach and water. Keep the humidity level in your home below 50% to prevent the growth of mold and mildew.
Dust and Wipe Surfaces
Dusting and wiping surfaces such as countertops, shelves, and tables can help to remove allergens. Use a damp cloth or microfiber cloth to trap the dust instead of dispersing it into the air.
