How to Check and Improve Air Quality in Your Home

Key Takeaways

How can I improve indoor air quality at home?

• Signs of Poor Air Quality: Allergies, odors, mold growth, and dust buildup signal issues.
• Practical Checks: Use air quality monitors, replace HVAC filters, and look for visual clues.
• Improvement Steps: Upgrade to HEPA filters, use air purifiers, and improve ventilation.
• Professional Help: Professional air testing and HVAC maintenance offer comprehensive solutions.

Spending time indoors is a big part of daily life—especially in Las Vegas, where scorching summer temperatures often make air-conditioned spaces a welcome escape. However, have you considered the quality of the air you’re breathing at home? Many people are surprised to learn that indoor air can be 2–5 times more polluted than the air outside. Dust, pet dander, mold spores, and chemical pollutants can accumulate over time, leading to unhealthy air that affects both comfort and well-being.

The good news is that you don’t need expensive tools or specialized knowledge to check and improve your home’s air quality. With a few practical steps, you can create a cleaner, healthier environment for you and your family.

Why Indoor Air Quality Matters

When people think about pollution, outdoor sources—like traffic, industry, and smog—tend to come to mind. Yet the air inside your home can be just as problematic, particularly if ventilation is lacking or maintenance is neglected. Las Vegas’s dry, dusty climate exacerbates this issue, making it easier for allergens and dust to infiltrate your living spaces.

Here are a few signs that your indoor air quality may need attention:

• Frequent Allergies: Sneezing, coughing, or itchy eyes at home often signal pollutants like dust mites, pet dander, or pollen.
• Lingering Odors: Musty smells may indicate mold, while chemical odors can stem from cleaning supplies, paints, or newly purchased furniture.
• Dust Accumulation: If you’re constantly wiping down surfaces, airborne particles may be circulating unchecked.
• Mold Growth: Damp areas, such as bathrooms and HVAC systems, are prime locations for mold spores, which can contribute to respiratory issues.

Poor indoor air quality isn’t just about minor annoyances. Prolonged exposure can worsen asthma, trigger allergies, and contribute to long-term respiratory problems. Fortunately, there are effective ways to assess your home’s air quality and take action.

How to Check Air Quality in Your Home

If you suspect air quality issues but aren’t sure where to start, consider these approaches:

1. Use an Indoor Air Quality Monitor

Air quality monitors are user-friendly devices that offer insights into the air you breathe. They measure pollutants like particulate matter (PM2.5), volatile organic compounds (VOCs), carbon dioxide, and humidity levels. Many modern options provide real-time readings and notifications if levels become concerning.

Pro Tip: 

For accurate results, place the monitor in spaces where you spend the most time, such as bedrooms, kitchens, or living areas.

2. Check and Replace Your HVAC Air Filter

Your HVAC system plays a vital role in maintaining clean air throughout your home. Its filter traps particles like dust, pollen, and pet hair, preventing them from recirculating. However, a clogged filter reduces efficiency and allows pollutants to linger.

• Check filters monthly and replace them every 1–3 months, depending on use.
• For homes with pets or allergy concerns, more frequent replacements may be necessary.
• Consider upgrading to HEPA filters, which capture smaller particles more effectively.

3. Look for Visual and Olfactory Clues

Your home often gives subtle hints about its air quality. Keep an eye out for:

• Mold spots in damp areas like bathrooms or near vents.
• Dust settling quickly on surfaces.
• Stale or musty odors, which can indicate moisture or mold issues.
• Worsening allergy or asthma symptoms among household members.

4. Schedule Professional Indoor Air Testing

While monitors offer valuable information, professional indoor air testing provides a more comprehensive analysis. Experts use advanced tools to detect hidden pollutants—like mold, harmful gases, or excess dust—that basic monitors may miss.

By uncovering specific issues, professionals can help you develop a targeted plan for cleaner air.

Practical Ways to Improve Indoor Air Quality

Once you’ve assessed your air quality, it’s time to make improvements. Here are effective solutions for creating a healthier indoor environment:

1. Upgrade Your HVAC Filters

Standard air filters remove basic pollutants, but high-efficiency options—like HEPA filters—capture up to 99.97% of particles, including dust, allergens, and mold spores. A simple filter upgrade can make a noticeable difference in air quality.

2. Schedule Regular HVAC Maintenance

Routine maintenance keeps your HVAC system running efficiently while reducing indoor pollutants. During a professional inspection, technicians typically:

• Clean system components, such as coils and vents.
• Replace or upgrade air filters.
• Check for mold or dust buildup in ducts.

Well-maintained HVAC systems circulate cleaner air, contributing to a more comfortable living space.

3. Add an Air Purifier

Air purifiers are particularly useful in homes with pets, allergies, or persistent odors. These devices filter out pollutants and neutralize unpleasant smells, improving overall air quality.

Choose purifiers with HEPA filters for optimal results, and position them in rooms where air quality concerns are most significant.

4. Improve Ventilation

Good airflow prevents pollutants from building up indoors. When weather allows, open windows and doors to let fresh air circulate. In areas like kitchens and bathrooms, exhaust fans are essential for removing moisture, cooking fumes, and odors.

5. Manage Indoor Humidity

While Las Vegas is known for its dry air, indoor humidity can still rise—especially in bathrooms or kitchens. Keeping humidity levels between 30–50% reduces the risk of mold growth and discourages dust mites. Use dehumidifiers or exhaust fans to maintain balanced levels.
