The Original DeMite Laundry Additive is the most allergist-recommended laundry solution for people with dust mite allergies. Use only one and one-half (1-1/2) tablespoons of DeMite in hot, warm or cold water to eliminate dust mite allergen in your bedding (including your mattress pads) or clothing. Regular detergents alone won't solve your dust mite problem, unless you wash in very hot water (at least 140 Degree), which can cause fabric deterioration, color fading and is a scalding hazard. However, the active ingredients in DeMite eliminate mite allergens with each wash, regardless of your choice of water temperature. in fact, DeMite's active ingredients have gone through formal testing resulting in studies being published in leading professional journals to substantiate its claims, which is not the case with other products. This concentrated additive has been recommended by allergists for their dust mite allergic patients since 1995, because it works. DeMite is non-toxic, completely safe and the best alternative to washing your bedding in extra-hot water to remove dust mite allergens.
