Indoor Allergen Analysis (IAA) & Good Health
Will Legend is currently the only company in Hong Kong that provides “Indoor Allergen Analysis (IAA)” solution to find out the root cause of allergic reactions, and then through maintaining a good environmental hygiene to achieve good health. We collect samples of dust or air from your home or workplace and send them to laboratories in the US or Canada to identify and recognize common environmental allergens among Hong Kong allergy sufferers. These include the most common dust mite, followed by cockroaches (which account for 45% of allergies). The IAA uses Luminex XMAP® system to detect 14 common indoor environmental allergens, such as dust mites (Der p 1, Der f 1, and Mite Group 2), cats (Fel d 1), dogs (Can f 1), mice (Mus m 1), rats (Rat n 1), cockroaches (Bla g 2), Alternaria (mold (fungus) Alt a 1), birch trees (Bet v 1), and Timothy grass (Phl p 5) pollen from the source.

Will Legend goes to the home, and the workplace to collect dust or air samples, and analyse whether the envrionmental allergens are dust mites, animals (rats, cats & dogs), cockroaches, pollen, moulds, or bacteria etc.
A written Indoor Envrionmental Allergen Analysis Report (Envrionmental Allergen Analysis Results) will be sent to you after samples are analyzed by the ISO/IEC 17025:2017 accredited Environmental Testing Laboratory. Once envrionmental allergens are located, not only a range of green-deep cleaning solutions will be recommended, but also allergy relief products. This is because Will Legend works things out as a whole over a single symptom.
- Improve air flow and ventilation in homes, and the workplaces – leave interior doors open, run exhaust fans in bathrooms and kitchens

- Use certified green or natural cleaners
- Schedule regular green-deep cleaning solutions to remove dirt, stains, envrionmental allergens like dust mites, animal dander, pollens, and moulds (molds) etc.
- Use dehumidifiers to keep humidity level below 50%
- Keep windows closed when outdoor pollution is high, or during peak pollen times
- Avoid conventional scents like fragrance or candles which may contain toxic chemicals and VOC
- Use air cleaners (air purifiers) to reduce indoor envrionmental allergen
