Preventing dust mite infestations in the home may involve maintaining a low humidity level, cleaning regularly using a vacuum with an allergen trapping filter, and removing carpets and upholstered furniture. Additionally, using allergen impermeable pillow and mattress covers and washing bedding in hot water can reduce dust mites, states MedicineNet.
Dust mite infestations can be prevented in several ways, however dust mites cannot be entirely eliminated from a home, regardless of how clean it is kept. Since dust mites thrive in humid conditions, using a dehumidifier or air conditioner is recommended to lower the humidity level in a home to 50 percent or less. It’s also important to change furnace and air conditioner filters regularly to reduce dust mites, according to WebMD. A vacuum with a HEPA filter or double micro filter bag is most effective at trapping allergens that permeate a vacuum’s exhaust.
Replacing wool and feather bedding items with synthetic materials, and carpet with wood, tile or linoleum is advised for reducing dust mite levels in the home. Removing fabric curtains and upholstered furniture from a home can also help to prevent dust mite infestations, according to MedicineNet.
Allergen impermeable and dust-proof mattress and pillow covers may help to prevent exposure to dust mites, notes WebMD. Additionally, washing bedding, linens and other fabric items such as stuffed animals in a water temperature of 130-140 degrees Fahrenheit can kill dust mites. Dust mites can also be killed by freezing them, according to MedicineNet.
