Think Your Home’s Air Is Clean? Think Again.

Most homeowners assume their indoor air is clean simply because their home looks tidy or smells fresh. But did you know that the air inside your home can be 2–5 times more polluted than outdoor air? From invisible dust and pollen to bacteria and chemical vapors, these pollutants can affect your family’s comfort and health without you realizing it.

At Smith Air Conditioning, we specialize in improving indoor air quality with Lennox PureAir™ systems—but first, let’s bust some common IAQ myths that may be putting your home at risk.

Myth 1: “If My House Is Clean, My Air Is Clean.”

You can vacuum, dust, and mop daily, but indoor air pollution is mostly invisible. Common contaminants include:

  • Pollen and pet dander

  • Mold spores

  • Dust mites

  • Bacteria and viruses

  • VOCs (volatile organic compounds) from cleaning products and furniture

Even spotless homes can have air that triggers allergies, asthma, or respiratory irritation.

Solution: A whole-home air purification system like Lennox PureAir™ removes up to 99% of airborne particles, including microscopic contaminants you can’t see.

Myth 2: “Changing My Air Filter Is Enough.”

Standard 1-inch filters in HVAC systems only trap larger particles like dust and lint. They do very little to remove bacteria, mold spores, or chemical vapors that affect your health.

  • Basic filters: Capture visible dust only

  • HEPA or MERV 16 filters: Capture allergens and bioaerosols

  • Lennox PureAir™ System: Neutralizes odors, VOCs, and particles as small as 0.01 microns

Solution: Upgrading your filtration is key. PureAir™ combines high-efficiency filtration with a powerful carbon layer to remove particles and neutralize odors throughout your home.

Myth 3: “I Don’t Need Air Purification if I Have Good Ventilation.”

While proper ventilation helps, it can bring outdoor pollutants inside—like pollen, smoke, and even exhaust fumes. In today’s tightly sealed, energy-efficient homes, pollutants often circulate indoors without escape.

Solution: Pairing your HVAC system with a whole-home air purification system ensures that the air moving through your ducts is filtered, cleaned, and fresh before it ever reaches your living spaces.

Myth 4: “Indoor Air Quality Only Matters for People with Allergies.”

Poor indoor air quality affects everyone, not just allergy sufferers. Prolonged exposure to airborne pollutants can cause:

  • Headaches and fatigue

  • Eye, nose, and throat irritation

  • Exacerbated asthma symptoms

  • Increased risk of respiratory illness

Solution: Lennox PureAir™ helps protect your family’s long-term health, creating a safer, cleaner environment for everyone in your home.
