You already have a diagnosis that is one step taken already.
When you come in contact with any allergens use a mask to minimise the exposure as much as you can if you cannot completely avoid it.
These are the few allergens that you have come to notice which is good, also it is better to know more.
Next Steps
You should get an allergy profile done to identify all the allergens.
Once that is done then the next step would be to start immunotherapy for the identified allergens.
