Why Indoor Air Quality (IAQ) Matters
Indoor Air Quality (IAQ) is crucial for our health and comfort, yet it's often overlooked in homes and workplaces. Poor IAQ can increase the risk of respiratory illnesses, worsen allergies, and even contribute to long-term health issues such as lung cancer. Dust, chemicals, and pollutants from household products, outdoor air, and building materials all affect the air we breathe. By understanding and managing IAQ, you can protect your family's health, improve comfort, and even enhance the efficiency of your HVAC system.

Indoor air quality isn't just about comfort — it's about protecting your family. We've helped many homeowners who thought they were dealing with "just allergies" or "just dust," only to discover real air quality issues that needed attention.
Cleaner Air. Better Health. Peace of Mind.
Five Key Areas Affecting Your Home's Air
Here are five key areas to focus on for better indoor air quality:
1 Air Pollution & the Flu
Breathing polluted air makes it easier to catch the flu and can make symptoms worse. Pollutants like PM10 particles, diesel exhaust, nitric oxides, sulfur dioxide, and ozone can carry flu viruses farther and keep them airborne longer. Pollution also inflames the bronchial tubes and triggers the release of immune chemicals called cytokines, which worsen symptoms.
Protect yourself: Get the annual flu vaccine, use a high-performance air cleaner to remove airborne contaminants, and support your immune system with proper nutrition and supplements like zinc, echinacea, and probiotics. CDC Flu Guide →
2 Household Products That Impact IAQ
Many everyday products release chemicals into the air that can irritate the lungs or trigger allergies. Common offenders include aerosols, scented candles, dryer sheets, plug-in air fresheners, incense sticks, and fragrance oils. Minimizing or carefully using these products can significantly improve indoor air quality.

3 Air Quality & Lung Cancer
Even non-smokers are at risk of lung cancer due to environmental exposures. Radon, secondhand smoke, asbestos, and outdoor air pollution—especially fine PM2.5 particles—are major contributors. Pollutants like polycyclic aromatic hydrocarbons (PAHs) can damage DNA in lung cells, while long-term exposure causes inflammation and promotes cell growth that may turn cancerous.
Protective steps: Avoid smoking, use air purifiers at home, reduce exposure to chemicals, test for radon, and lead a healthy lifestyle with proper diet and exercise. American Lung Assoc. →
4 Household Dust & Chemicals
House dust is more than dirt; it contains skin cells, fibers, bacteria, pollen, and chemicals from household products. Dust can accumulate pollutants like flame retardants, phthalates, pesticides, and even nonylphenol ethoxylates from cleaners. Infants and toddlers are particularly at risk because of hand-to-mouth behaviors. Dust exposure has been linked to hormone disruption, reproductive issues, obesity, and even leukemia in children.
Reduce exposure: Frequent hand washing, HEPA vacuums, damp dusting, and choosing furniture and products without added flame retardants help minimize risks.
