Install Allergen-Proof Bedding and Purify Air

Tools Required: Dust mite-proof mattress encasements, pillow covers, and a HEPA air purifier.

1. Encase the mattress and all pillows in certified allergen-proof, zippered covers to prevent dust mite colonization.
2. Place a HEPA-rated air purifier in the bedroom and run it continuously to reduce airborne dander and dust.
3. Wash all bedding weekly in water heated to at least 130°F (54°C) to kill mites.
4. Verification: Monitor symptom intensity over 14 days; a significant decrease in morning sneezing indicates successful mitigation of the trigger.
