Allergy sufferers, listen up: your bedroom may be the source of your sniffles. Dust mites are the most common cause of allergies from house dust, according to the American College of Allergy, Asthma, and Immunology. These tiny bugs live in pillows, mattresses, carpets, and upholstery, and even if you keep a sparkling clean home, they can still burrow their way into your bedding. Soothe your sneezing by washing all of your bedding in hot water weekly. You can also invest in tightly woven encasements with zippers that fully seal, like the following 12 allergy-proofing products.

Pillowcases

Pillows
