One method involves seeding an article with house dust mites, exposing the article to conditions that promote accelerated growth of house dust mites (, block), washing the article to remove house dust mites (, block), testing the washed article to determine that the level of dust mite remaining in the washed article is below a predetermined level (, block), repeating the washing step a number of times approximating the number of washes the article is expected to undergo during its normal useful lifetime (, block) and finally passing the article through a series of quality control tests (andblock) so that the article may be assured as washable to control its mite and allergen levels without loss of integrity and safety over a plurality of wash cycles.
