🏠Controlling Your Environment to Reduce Allergens
Reducing exposure to allergens like pollen, mold, dust mites, and pet dander can significantly improve symptoms and reduce the need for medication.
🐾 Animals (Pet Dander)
| DO | AVOID |
| Keep pets out of the bedroom and off fabric furniture | Letting pets sleep in beds or on soft furnishings |
| Bathe/groom pets regularly | Skipping pet cleaning, especially after outdoor exposure |
| Use HEPA air purifiers in pet-heavy rooms | Assuming pet dander won’t spread if the pet is only in certain rooms |
| Wipe pets’ feet & legs after being outside | Bringing outdoor allergens indoors with pets |
💡 Best long-term solution: Consider allergy shots (immunotherapy) for pet allergies.
🛏️ Dust Mites
| DO | AVOID |
| Use zippered allergen-proof covers on mattresses and pillows | Using regular bedding without encasements |
| Wash sheets/blankets weekly in hot water (140°F) | Letting bedding go unwashed for long periods |
| Keep humidity below 45% (use A/C or dehumidifier) | High humidity environments—check with a humidity gauge |
| Vacuum frequently, especially soft surfaces | Shampooing carpets (not effective for dust mites) |
| Freeze or hot dry stuffed animals | Letting stuffed toys sit uncleaned |
🌼 Pollen
- Keep windows closed during pollen season
- Best times to go outside: Cool, damp, low-wind days
- Worst times: Dry, hot, and windy days (esp. late morning to early afternoon)
- Remove outdoor clothes before lying on beds
- Wipe pets after outdoor exposure
- Use pollen count websites like:
🌫️ Mold
| DO | AVOID |
| Remove moldy items from the home | Keeping damp items/clothing |
| Clean bathrooms/tile often with anti-mold agents | Letting mold build in grout or corners |
| Use mildew-resistant paint or mix in mildewcide | Painting over mold without treatment |
| Keep plants to a minimum or use mold-free soil | Indoor plants with constantly moist soil |
| Dehumidify damp areas | Allowing excess humidity indoors |
Effective mold cleaners:
Captan (Orthofungicide), Zephiran, Lysol spray, Clorox
🌬️ Air Filtration
- Whole-house air filtration is best. Use the highest grade filter your system can handle.
- Set the fan to “on” (not “auto”) for continuous air cleaning.
- Replace filters regularly to keep filtration efficient.
Stand-Alone Air Purifiers:
| Type | Pros | Cons |
| Disposable filter | Lower cost up front | Ongoing filter purchases |
| Washable/reusable filter | Long-term savings | Higher initial cost |
| Ozone-producing units | Often minimal effect | May irritate lungs (check specs) |
🔒 For best use: Keep windows and room doors closed while running.
