Check the humidity level in your home. Mold and mildew can grow inside your home if the humidity is too high. Most people are comfortable at a humidity level of nearly 50 percent. You may need to use a dehumidifier to help control this level. Be a dustbuster.
Dust is a powerful allergen which accumulates easily when homes are closed up during the winter.
To help control dust, wipe your furniture and vacuum routinely, but wear a face mask while doing these chores. Make sure furnace filters are clean or replaced as recommended by the manufacturer because heating vents can blow accumulated dust throughout your home. Also, replace the filters on attached humidifiers. Watch the weather. Although there's little you can do to control the weather, you can record it to determine if your allergies are triggered by weather changes.
