New Jersey experiences four distinct seasons, each bringing its own set of weather patterns, temperatures, and airborne contaminants. While most residents prepare their homes for changes in outdoor weather, few consider how these seasonal transitions affect indoor air quality (IAQ)—which can often be up to five times more polluted than outdoor air, according to the EPA.
Understanding how each season impacts IAQ is essential for creating a healthier living environment. In this article, we’ll explore how weather in New Jersey affects indoor air quality and what homeowners can do to address these challenges.
Spring: Allergy Season and Pollen Invasion
Spring in New Jersey brings blooming flowers, budding trees—and a surge in airborne pollen. As windows open to let in fresh air, pollen, dust, and other allergens easily enter the home.
Common IAQ challenges in spring:
- Tree and grass pollen accumulation indoors
- Mold growth due to increased humidity and rainfall
- Higher dust levels from spring cleaning activities
Solutions:
- Install high-efficiency HVAC filters (MERV 11+)
- Keep windows closed during high pollen days
- Use an air purifier in bedrooms and living spaces
- Schedule a professional air duct cleaning to remove allergens
Summer: Humidity and VOC Buildup
Summers in New Jersey are hot and humid. That combination creates the perfect environment for mold, mildew, and dust mites, especially in poorly ventilated areas like basements and attics. Additionally, with air conditioning running constantly and windows closed, volatile organic compounds (VOCs) from furniture, paints, and cleaning products can accumulate indoors.
Common IAQ challenges in summer:
- Excess humidity encouraging mold and microbial growth
- Buildup of VOCs and household pollutants
- Poor air circulation in sealed indoor spaces
Solutions:
- Use a dehumidifier to keep indoor humidity between 30–50%
- Ventilate regularly using exhaust fans or open windows during cooler times
- Avoid using chemical-heavy products indoors
- Maintain your AC system and clean filters monthly
Fall: Mold Spores and Dust Accumulation
Fall in New Jersey is marked by cooler temperatures and falling leaves—but also by higher levels of mold spores from decaying foliage and dust accumulation as homes are sealed for winter.
Common IAQ challenges in fall:
- Outdoor mold spores entering the home
- Dust buildup in vents, registers, and ductwork
- Turning on the furnace for the first time stirs up accumulated particles
Solutions:
- Schedule HVAC system inspection before winter
- Clean ducts and vents
- Use an air purifier with HEPA filtration
- Remove shoes at the door to reduce tracking in mold spores
Winter: Dry Air and Circulated Contaminants
During New Jersey winters, homes are sealed tight to conserve heat, and HVAC systems operate constantly. This can lead to dry air, which irritates respiratory passages and skin, while circulating dust, pet dander, and other pollutants throughout the house.
Common IAQ challenges in winter:
- Low humidity drying out mucous membranes
- Increased indoor pollutants due to closed windows
- Potential buildup of carbon monoxide if HVAC systems aren’t ventilated properly
Solutions:
- Use a humidifier to maintain indoor humidity around 40%
- Have heating systems inspected for safety and efficiency
- Replace HVAC filters every 1–2 months
- Invest in a CO detector and indoor air monitor
Year-Round Tips for Better Indoor Air Quality
Regardless of the season, there are consistent steps homeowners can take to improve and maintain good IAQ throughout the year:
- Schedule professional air duct cleaning every 2–4 years
- Regularly change HVAC filters (more often if you have pets or allergies)
- Vacuum carpets and upholstery with HEPA-filter vacuums
- Avoid synthetic air fresheners that release VOCs
- Use natural cleaning products or those labeled “low-VOC”
- Introduce houseplants that naturally purify air (e.g., spider plant, peace lily)
Final Thoughts
From spring pollen to winter dryness, New Jersey’s seasonal shifts significantly influence the air quality inside your home. By understanding these seasonal dynamics and taking proactive steps, you can breathe easier, reduce allergy symptoms, and create a healthier indoor environment year-round.
