Using protective dust mite covers on your bed is one of the most effective steps you can take in the fight against indoor allergies. After all, your bed is the most common place for dust mites to live and breed. Dust mite encasings zip around your pillows, duvets, mattresses, and box-springs to form impenetrable barriers against dust mites, dust particles, and other small allergens. These covers will also kill the dust mites already living inside your bedding by cutting off access to their food supply, your dead skin cells. Our dust mite covers come in varying pillow and mattress sizes, pore measurements, fabrics, and breathability ratings. Some are even made with dye- and chemical-free material to offer an added benefit to those who have skin and chemical sensitivities.
