Toys with the asthma & allergy friendly™ certification mark are an ideal choice for those concerned with asthma and allergies. Toys bearing the asthma & allergy friendly™ certification mark have been scientifically tested and shown to be more suitable for people with asthma and certain types of allergies. These toys can be washed frequently to keep allergen levels low, and they do not contain harmful chemicals at levels known to trigger symptoms. The asthma & allergy friendly™ involves rigorous testing that includes: Surface and stuffing material analysis, allergen loading and demonstration of successful eradication, multiple machine wash testing, quality and safety testing. The asthma & allergy friendly™ Certification Program is operated by the Asthma and Allergy Foundation of America and Allergy Standards Limited.
