What Spring Allergens Can Most Affect Your IAQ?

What Spring Allergens Can Most Affect Your IAQ?

Signs of spring — such as increased daylight, climbing temperatures, blooming flowers, and the return of chirping birds — are very much welcome. Along with these spirit-lifting signs, you may also experience a common but less-welcome sign: bothersome allergies. To successfully limit your exposure to spring allergies, you’ll need to familiarize yourself with their sources. Here’s a closer look at the spring allergens that affect your air quality the most.


Pollen is the primary culprit of springtime allergies. Trees start releasing pollen at the start of spring. In New Jersey, grasses have two pollinating seasons, one of them being late spring. While pollen producers are found outside, pollen can easily find its way into your home through:

  • Open windows
  • Shoes and clothes
  • Long-haired pets

Once these microscopic particles are inside your home, they’re spread throughout your home by your HVAC system. Some of the symptoms you can experience when pollen is in your home’s air include:

  • Sneezing
  • Itchy ears, eyes, nose, and mouth
  • Congestion


Spring causes an increase in molds that thrive in humid conditions or live among sprouting plants. They grow and reproduce through spores, which travel through the air. When the spores get into your sinuses or lungs, they can cause unpleasant symptoms like:

  • Itchy, watery eyes
  • Runny nose
  • Congestion
  • Sneezing

Dust Mites

The higher humidity during the spring not only encourages mold growth but also increases the levels of dust mites. The fecal matter of these bugs triggers allergic reactions in some people.

These spring irritants can wreak havoc on your health and indoor comfort. Fortunately, you can limit them indoors through several HVAC solutions, such as changing your HVAC filter regularly, using an air-purification system that can work with your air conditioner, and investing in a dehumidifier to lower humidity levels.
