When most people think about air pollution, they picture smog-filled city streets or factory smokestacks, but the truth is, some of the worst air you breathe might be inside your own home or workplace. At Insight Environmental, we help people every day discover just how much their indoor environment can impact their health and what they can do to improve it. Clean indoor air isn’t just about what you add (like purifiers or filters), it’s just as much about what you avoid.
Let’s dive into the most common culprits that are silently affecting your air quality and how to steer clear of them so you and your family can breathe a whole lot easier.
Key Takeaways
- Avoid synthetic air fresheners, candles, and incense that emit harmful VOCs.
- Don’t ignore moisture issues. Mold thrives in damp environments.
- Cut down on dust and dander by cleaning often and using a HEPA vacuum.
- Say no to smoking indoors. Tobacco and vaping both degrade air quality.
- Watch for hidden chemical sources like household cleaners and new furniture.
- Ensure proper ventilation when cooking, cleaning, or using appliances.
- Skip the clutter. Less stuff = less dust and more airflow.
- Test for radon, mold, and other hidden pollutants regularly.
- Don’t assume your air is clean. Get professional indoor air quality testing.
Air Fresheners Aren’t So Fresh
We know that nothing beats a fresh smelling home or office, but plug-ins, sprays, and even scented candles often do more harm than good. These products release volatile organic compounds (VOCs), which are chemicals that can easily become airborne and irritate your eyes, throat, and lungs. Some VOCs have even been linked to long-term health problems.
What to Do Instead:
- Try natural options like essential oil diffusers (with good ventilation).
- Simmer herbs or citrus on the stove.
- Open windows when weather allows.
- Keep your home clean to prevent odors at the source.
Mold: The Hidden Invader
One of the biggest indoor air quality issues we test for is mold, which often grows where you can’t see it. Mold spores become airborne and can cause allergy symptoms, respiratory issues, fatigue, and more. Mold thrives in areas with moisture, especially in bathrooms, basements, and behind walls after a leak.
What to Avoid:
- Ignoring leaks or water damage, even minor ones.
- Letting humidity levels climb above 60%.
- Postponing cleanup after flooding or spills.
What to Do:
- Use a dehumidifier in damp areas.
- Fix leaks quickly and thoroughly dry affected materials.
- Schedule mold testing if you notice musty smells, persistent allergies, or water damage.
Smoke of Any Kind Is a No-Go
Whether it’s tobacco, cannabis, or incense, burning anything indoors impacts your air quality. Even secondhand and thirdhand smoke (residue that clings to walls, furniture, and fabrics) can expose you to harmful particles long after the smoke clears.
Vaping isn’t a great alternative either. While it may emit fewer particulates than smoking, it still releases fine aerosols that settle in your home’s air and surfaces.
What to Avoid:
- Smoking or vaping indoors.
- Burning incense or using scented candles frequently.
A Better Approach:
- Step outside to smoke or vape.
- Create designated outdoor smoking areas for guests.
- Use electric alternatives to candles if ambiance is what you’re after.
Toxic Cleaners and Chemical Overload
You may be cleaning your home, but at what cost? Many household cleaning products contain formaldehyde, ammonia, chlorine, and other VOCs, especially those with artificial fragrances. And that “lemony fresh” scent? It’s often a chemical cocktail.
New furniture, flooring, and paint can also off-gas harmful chemicals into your air, especially if they are made with synthetic materials.
What to Avoid:
- Overusing spray cleaners and air freshening sprays.
- Painting or installing new materials without proper ventilation.
- Using harsh cleaners in enclosed spaces.
What to Use Instead:
- Choose low-VOC or fragrance-free cleaning products.
- Go with natural options like vinegar, baking soda, and lemon.
- Let new furniture and flooring “air out” before full use.
- Always ventilate when cleaning or painting.
Poor Ventilation = Trapped Pollutants
When your home is sealed too tightly (common in newer, energy-efficient homes), the air can become stale and polluted. Without enough ventilation, pollutants build up over time, including moisture, carbon monoxide, radon, and household chemicals.
Proper ventilation helps flush out contaminants and bring in fresh air. It’s especially important when cooking, cleaning, or running gas-powered appliances.
What to Avoid:
- Keeping windows closed year-round.
- Skipping range hood use while cooking.
- Using gas stoves or space heaters without proper ventilation.
How to Improve Ventilation:
- Crack windows when outdoor air is clean and dry.
- Run exhaust fans in the bathroom and kitchen.
- Consider an energy recovery ventilator (ERV) for continuous fresh airflow.
- Get your HVAC system checked to ensure it’s circulating properly.
Clutter: More Than Just a Mess
A cluttered home doesn’t just stress you out, it also traps dust, dander, and allergens. Piles of clothes, books, and boxes collect particles that build up and release into your air every time you move them.
What to Avoid:
- Letting unnecessary items pile up on floors, shelves, or closets.
- Storing items in cardboard boxes (which attract dust and mold).
What Helps:
- Decluttering regularly—if you don’t use it, lose it.
- Vacuuming with a HEPA filter vacuum.
- Dusting with a damp microfiber cloth.
- Replacing cardboard with plastic storage containers when possible.
Pet Dander, Pollen, and Other Allergens
If you have pets or live in an area with high pollen counts, you’re probably already dealing with allergens floating around your home. Dander and pollen cling to furniture, rugs, and even your clothing. Once inside, they can be tough to remove without consistent cleaning.
What to Avoid:
- Letting pets on fabric-covered furniture or beds.
- Skipping regular grooming for pets.
- Leaving windows open during peak pollen season.
Steps to Take:
- Brush and bathe pets often (bonus points if you do so outdoors).
- Use an air purifier with a HEPA filter.
- Keep a no-shoes policy to avoid tracking in pollen.
- Wash linens, curtains, and area rugs regularly.
Neglecting Your HVAC System
Your HVAC system is your home’s lungs. If the system is dirty or poorly maintained, it could be recirculating dust, mold spores, pollen, and other pollutants.
We’ve found countless homes with HVAC systems that haven’t been serviced in years, and the difference in air quality after a professional cleaning is dramatic.
What to Avoid:
- Skipping HVAC maintenance.
- Using low-quality air filters.
- Running your system with dirty ducts or vents.
What to Do Instead:
- Change filters every 1–3 months (more often if you have pets).
- Schedule HVAC servicing at least once a year.
- Consider duct cleaning, especially after renovations or if you suspect mold.
- Upgrade to a higher MERV-rated filter if your system can handle it.
Radon: The Invisible Threat
Radon is an odorless, colorless radioactive gas that can seep into your home from the ground. It’s the second leading cause of lung cancer in the U.S. after smoking. Many homeowners don’t test for it, assuming it’s a non-issue, until it’s not.
What to Avoid:
- Assuming your home is safe without testing.
- Ignoring radon test results or postponing mitigation.
Smart Move:
- Schedule a radon test, especially if you’re in a high-risk area.
- Install a radon mitigation system if levels are elevated.
- Retest every 2–3 years or after major structural changes.
