The Air You Breathe Indoors Matters More Than You Think
Most people assume that pollution is something that happens outside — smog, car exhaust, factory emissions. But the truth is, the air inside your home can be two to five times more polluted than the air outdoors, according to the EPA.
Between Pennsylvania’s seasonal humidity, older homes in the Lehigh Valley, and tightly sealed modern construction, your indoor air can trap dust, pet dander, mold spores, and other contaminants that affect your comfort and health.
That’s where proper indoor air quality management comes in — and it’s something Faust Heating, Cooling & Electric can help with.
What Is “Indoor Air Quality”?
Indoor Air Quality (IAQ) refers to the condition of the air inside your home or business — especially as it relates to the health and comfort of occupants. Poor IAQ happens when pollutants build up faster than they can be filtered or ventilated.
Common indoor pollutants include:
Dust and pet dander
Mold spores (often from damp basements or humidifiers)
Pollen tracked in from outdoors
Volatile organic compounds (VOCs) from paints, cleaning products, and furniture
Carbon monoxide and combustion byproducts from heating systems
How Poor Air Quality Affects Your Health and Home
Breathing low-quality air doesn’t just cause sneezing — it can lead to a range of issues:
Allergies and respiratory irritation (especially for kids and seniors)
Headaches, fatigue, and brain fog from high VOC levels
Mold growth that can damage walls and furniture
Dry air problems, such as nosebleeds or cracked skin in winter
Higher energy costs, since dirty air restricts airflow and makes your HVAC work harder
Simple Steps to Improve Your Indoor Air Quality
Here are some effective ways to start breathing cleaner air today:
Replace HVAC Filters Regularly
Your system’s air filter is your first line of defense. Faust recommends changing filters every 1–3 months, depending on pets, allergies, and home size.
Schedule Regular HVAC Maintenance
Professional tune-ups ensure that your system isn’t spreading dust or mold. Faust’s technicians clean coils, check ducts, and optimize airflow for better IAQ.
Control Humidity Levels
Both excess moisture and overly dry air can cause issues. Whole-home humidifiers and dehumidifiers keep levels between 30–50%, ideal for comfort and health.
Add Air Purifiers or UV Light Systems
Advanced air purifiers trap tiny particles, while UV lights can kill bacteria and mold spores circulating through your ductwork. Faust installs systems compatible with most HVAC setups.
Improve Ventilation
Make sure exhaust fans in kitchens and bathrooms are functional, and consider a heat recovery ventilator (HRV) if your home is tightly sealed.
