Many of us take the air we breathe for granted. We open windows, clean surfaces, and think the air in our homes is healthy. In reality, the concentration of pollutants indoors is often 2 to 5 times higher than that on a busy outdoor street.

If you haven’t been diligent about cleaning your air ducts, the air in your own home may be causing you more harm than you realize.

Here are four of the most common air pollutants that, with the help of air duct professionals, are more than manageable.

1. Carbon Monoxide

Carbon monoxide is an odorless, colorless, and tasteless gas that’s incredibly dangerous and oftentimes lethal. Because there are few warning signs flagging its presence, carbon monoxide is possibly the most frightening on our list. Carbon monoxide is produced by burning charcoal, wood, gasoline, propane, or other types of fuel. A buildup of CO₂ causes carbon monoxide poisoning, a silent killer for both animals and people.

Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea or vomiting, shortness of breath, blurred vision, confusion, and loss of consciousness. Aside from maintaining clean air ducts, please ensure your home has a working CO₂ monitor.

2. Mold

Have your allergies popped up seemingly out of nowhere? While it might be a cold or it might be the season, your allergies may also be triggered by indoor mold growth. Mold is commonly found in areas of your home with excess moisture, such as bathrooms and leaky roofs. However, mold can grow on just about anything that’s exposed to moisture, including paints, wallpaper, upholstery, and carpet.

Symptoms of allergic reactions exacerbated by mold include wheezing, coughing, headaches, and skin irritation. Excess mold growth can even trigger asthma attacks.

3. Secondhand Smoke

If you’ve ever lived with smokers, you know how long the smell of smoke can linger in the air. But it’s not just a smell. Secondhand smoke, also known as environmental tobacco smoke (ETS), contains more than 7,000 substances.

Secondhand smoke is a mixture of tobacco products that haven’t fully burned and the smoke exhaled by smokers. Exposure to secondhand smoke can cause eye, nose, and throat irritation as well as lung cancer and other long-term respiratory ailments.

4. Lead Particles

Lead was commonly used in house paint up until the late 1970s. While many are warned against the dangers of consuming lead products, most are unaware that lead particles can also become airborne. Air ducts collect lead particles and, if ducts aren’t properly cleaned, these particles may spread throughout your home.

Long-term exposure to lead, or lead poisoning, has incredibly serious side effects including brain, kidney, and nerve damage. Young children exposed to lead have an increased likelihood of developing attention deficit disorder (ADD), behavior problems, and stunted growth.

What Can I Do?

Blocked vents are a common cause of carbon monoxide leaks and the dangerous buildup of other toxic air impurities. Because ventilation systems are designed to move impurities out of your home, when your air ducts are clogged, these impurities become trapped and may eventually spill out. Having your air ducts professionally cleaned will help your ventilation system work better for your home.


Having your air ducts professionally cleaned is more than a bothersome annual chore. It’s a step towards breathing easier at night with cleaner air and peace of mind. Keep your home clean and your household safe.
