asthma and allergy proof. For allergy control, covering your box spring with a hypoallergenic cover is critical. Allergy Guard Direct Inc. has been making bedding for 25 years. We started selling basic bedding such as sheets and towels and ultimately developed a line of protective allergy covers. We are totally vertical so we control the entire process. We are the factory and make sure we produce the highest quality covers we can. Because AGD makes the products and sells directly to the consumer, we offer unbeatable prices for our customers.
