Spring in St. Louis brings blooming flowers, warmer temperatures—and for many, relentless allergies. Pollen, dust, and mold spores can make life miserable, even indoors. Fortunately, AL-DON offers several ways to improve your indoor air quality… which can help reduce allergy symptoms and create a healthier home environment! Here’s how:
Use an Air Purifier
Air purifiers help trap airborne allergens like pollen, pet dander, and dust mites. Look for one with a HEPA filter, which captures particles as small as 0.3 microns. Consider models with activated carbon filters to help reduce odors and volatile organic compounds (VOCs) as well.
A great option for an Air Purifier would be the Air Scrubber Plus®. Watch the video below to see how it works.
Upgrade Your HVAC Filters
Your HVAC system plays a crucial role in indoor air quality. Replace or upgrade your air filters regularly, especially in allergy season. Choose MERV 11 or higher filters to trap smaller allergens without restricting airflow. Change filters every 1-3 months for the best results.

Control Humidity Levels
Dust mites and mold thrive in humid environments. The experts at AL-DON recommend to keep indoor humidity between 40-50% to reduce allergens in the Midwest region. Use a dehumidifier in damp areas like basements and bathrooms, and fix any leaks to prevent mold growth.

Keep Windows and Doors Closed
While fresh air is tempting, open windows can let in large amounts of pollen. Instead, use air conditioning with a clean filter to keep your home cool and pollen-free.

Vacuum and Dust Regularly
Vacuum with a HEPA filter at least twice a week to reduce allergens trapped in carpets and upholstery. Dust surfaces with a damp cloth to prevent particles from becoming airborne.
By taking these steps, you can significantly improve indoor air quality and reduce allergy triggers this spring.
