Common Sources for Indoor Allergens


When allergy season strikes, the last place you want to feel miserable is in your home. Your home should provide relief from your allergies, not make them worse. Unfortunately, many homeowners ingest allergens 24/7 due to poor indoor air quality. What are some common sources of indoor allergens, and how can you eliminate them?

Indoor Allergens to Watch Out For

Every allergen found outside can also be found inside. Before we discuss their sources, let’s take a closer look at the allergens to avoid.

  • Dust and Dust Mites
  • Mold
  • Mildew
  • Pollen
  • Dander
  • Hair
  • Dirt
  • Chemicals

Sources of These Indoor Allergens

So, how do these allergens travel through your home? They catch a ride on many different vehicles. If you have experienced allergic symptoms within your own home, the source was likely one of the following.

1.   Carpet

Carpet traps allergens in its fibers and slowly releases them into the air over time. Particularly in areas with high foot-traffic, like hallways, dust, dirt, and moisture accumulate beneath the pile. Regular vacuuming helps, but only professional carpet cleanings penetrate beneath the fibers and fully eliminate allergens.

2.   Pets

Even if your pet has little to no hair, every animal produces some sort of allergen. Fur, dander, tiny bugs, dirt, and pollen cling to a pet’s coat and become airborne inside the house. Constant brushing and grooming are important to maximize indoor air quality.

3.   Old Mattresses

Few homeowners even think about the state of their mattresses, but countless allergens can hide in old or dirty beds. Make sure you use a mattress cover and clean it along with your bedding.

4.   Dirty Filters

Your HVAC system also plays a vital role in your home’s indoor air quality. Clogged air filters prevent clean air from cycling through your home, which means the same dirty air continues circulating until something is done. Change your air filter monthly or as often as the manufacturer recommends.

5.   Moist Areas

Mold and mildew thrive in warm, damp environments. Attics and basements are particularly susceptible to mold growth. Particularly if you live in a humid climate, keep an eye out for mold growth in your home. Dehumidifiers help prevent excess moisture in the air.

6.   Plants

Many homeowners keep indoor plants, which actually serve as natural air cleaners. However, proper plant care is important to fungi prevention.

7.   Vents

Dust can settle inside your ductwork, blowing through your air when the heat or air conditioning turns on. Additionally, pests often leave droppings inside your vents, which can cause long-term health effects when ingested. Clean your vents once or twice a year to improve indoor air quality.

8.   Dirty Laundry

Whatever you do, don’t leave dirty or wet laundry sitting in one place for too long. Mold spores develop quickly inside damp piles of clothing, and dirty baskets harbor bacteria.

9.   Leaks or Drafts

If the air quality index is low outside, drafty doors and windows can potentially reduce the air quality inside as well. Check the seals around your home’s openings and exits to ensure no air is leaking in.

10.   Strong Cleaners

Bleaches, household cleaners, air fresheners, etc. are laden with chemicals that become airborne, harming your lungs when ingested. Natural cleaning products reduce the number of toxins in the air, but if natural products aren’t for you, make sure to ventilate. Fans, open windows, and air purifiers help eliminate toxins and chemicals from strong cleaners.
