1. Smoke
Cigarette and cigar smoke are among the most harmful indoor air pollutants, posing health risks to both smokers and non-smokers alike. Even smoke from just outside—like near a drafty window or door—can easily find its way in and reduce your IAQ.
The best choice is to avoid smoking indoors altogether. Smoke doesn’t simply vanish after the cigarette is extinguished—it lingers and spreads throughout your living space for hours. When guests who smoke come over, encourage them to smoke outside. It’s not about being impolite—it’s about safeguarding your home’s air and your family's health.
2. Volatile Organic Compounds (VOCs)
VOCs are chemical pollutants that negatively impact indoor air and are surprisingly common in everyday household products. You’ll find them in paints, aerosol sprays, cleaners, scented candles, air fresheners, and even brand-new carpets or furniture.
Because prolonged exposure can lead to serious health concerns—including some forms of cancer—it's wise to switch to low-VOC or VOC-free alternatives whenever possible to help protect both your air and your wellbeing.
3. Radon
Radon is a naturally occurring gas that can enter your home through cracks in the foundation and become trapped inside. Although invisible and odorless, long-term exposure to radon has been linked to lung cancer—even in individuals who have never smoked.
Utah homes are particularly prone to elevated radon levels, yet many homeowners are unaware due to lack of testing. If your radon levels measure above 4 pCi/L, professional radon mitigation is recommended. Installing a mitigation system can significantly lower radon levels and help create a safer indoor environment.
4. Pollen
If you suffer from allergies, pollen can be one of your worst enemies. It makes its way indoors through open windows and doors—or by clinging to clothing, skin, and pets. Once inside, pollen tends to settle on soft surfaces like couches and bedding.
To help manage indoor pollen, keep your windows closed during peak pollen seasons, switch out fresh flowers for houseplants, and use an air purifier. Change your clothes when you get home and clean your pets’ fur and paws before letting them inside. On high pollen days, check your local forecast and consider staying indoors or wearing a mask outside.
5. Pet Fur and Dander
As much as you love your furry friends, their fur and dander can compromise your home’s air quality. These particles become airborne and settle into your carpets, furniture, and vents—especially if not managed regularly.
Brushing your pets every day can help, and it’s best to do this outdoors, away from doors and windows. If DIY grooming isn’t your thing, consider using a local groomer—or a mobile groomer who can handle the job right outside your home.
6. Mold Spores
Mold spores are tiny and often undetectable to the eye, but they’re present in many homes. They can enter through open doors, windows, leaks, or even attach to clothes and pets. Once inside, they can trigger allergy symptoms or respiratory issues.
To help limit mold exposure, ensure your home is well-ventilated and consider installing a whole-home air purification system that can trap and eliminate spores from the air.
7. Pesticides
Pesticides from outside can easily make their way into your home and deteriorate your IAQ. These chemicals often enter through open windows, doors, or ventilation systems—especially during spring when yard treatments are common.
To avoid pesticide exposure indoors, use natural alternatives for weed and pest control, or consult a landscaper who uses eco-friendly methods. Avoid spraying any chemical treatments directly near windows or entryways.
8. Dust
You’re probably familiar with dust, but many don’t realize it’s a blend of tiny particles—ranging from skin cells and pet hair to insect droppings and textile fibers. All of these micro-pollutants contribute to poor air quality.
Frequent cleaning is essential for keeping dust levels low. Start by removing wall-to-wall carpeting, vacuuming daily, and wiping down hard surfaces. Don’t forget to deep-clean upholstered furniture, curtains, and mattresses. Installing a whole-home air filtration system and replacing your HVAC filters regularly can also make a big difference.
