How can I prevent dustmites and commen allergens in my mattress?
If your main concern is common allergens, such as dustmites, using an unbleached, undyed organic cotton mattress dustmite barrier encasing will definitely help as well as purchasing a new pillow or at least a dustmite cover for your current pillow. Washing your bedding in hot water every week and vacuuming your mattress with a HEPA vaccum will also help reduce allergens and particles. Also, make sure your mattress has proper ventilation as well to prevent mold growth.
