We provide a full range of testing for mattress encasements that are designed to prevent Bed Bugs, Dust Mites, & Allergens. For encasements we provide a 3-stage level of testing for bed bugs to confirm that they cannot feed through the fabric, escape through the zippers or the zipper closure, and that the eggs will not pass through the zipper teeth. With allergens and dust mites we can also focus on the fabric, the zipper, and zipper closure for containment ability. For allergens we offer both 2 traditional methods… the ‘bead agitation’ method and the ‘vacuum method’. Needless-to-say, we are a full service company for mattress encasements.
