IS YOUR INDOOR AIR MAKING YOU SICK?
Most people spend 90% of their time indoors, yet indoor air quality is often worse than outdoor air. Recognize these warning signs:
- 🤧 Persistent allergies, congestion, or respiratory issues
- 🤧 Unexplained headaches, fatigue, or difficulty concentrating
- 🤧 Worsening asthma symptoms indoors
- 🤧 Musty or chemical odors in your home
- 🤧 Symptoms improve when you leave the house
- 🤧 New construction or recent renovations
- 🤧 Children, elderly, or immunocompromised family members
- 🤧 Poor ventilation or sealed, energy-efficient home
- 🤧 HVAC system concerns or dirty filters
- 🤧 Located near highways, industrial areas, or allergen sources
COMMON INDOOR AIR POLLUTANTS
We test for a comprehensive range of contaminants that affect your health:
Causes allergies, asthma, respiratory infections
Pollen, dust mites, pet dander, cockroach debris
Formaldehyde, benzene from furniture, paint, cleaning products
PM2.5, PM10 from cooking, dust, outdoor pollution
Poor ventilation indicators, combustion byproducts
Radioactive gas from soil (common in Missouri basements)
WHY COMPREHENSIVE AIR QUALITY TESTING MATTERS
Indoor air quality affects every breath you take. Here's why professional testing is essential:
PROTECT YOUR FAMILY'S HEALTH
Poor indoor air quality contributes to or worsens:
- Asthma attacks and breathing difficulties
- Allergic reactions and sinus infections
- Headaches, fatigue, and "brain fog"
- Eye, nose, and throat irritation
- Long-term respiratory disease
- Cardiovascular problems
ESPECIALLY CRITICAL FOR VULNERABLE GROUPS
Certain family members are at higher risk:
- Children: Developing lungs, breathe more air per body weight
- Elderly: Weakened immune systems, existing conditions
- Asthma sufferers: Triggers can be life-threatening
- Pregnant women: Protects both mother and baby
- Immunocompromised: Greater sensitivity to pollutants
INVISIBLE THREATS YOU CAN'T DETECT
Many dangerous pollutants are odorless and invisible:
- Radon gas has no smell or color (causes lung cancer)
- VOCs often undetectable until concentrated
- Mold spores invisible to the naked eye
- Fine particulate matter (PM2.5) microscopic
- Carbon monoxide is the "silent killer"
MODERN HOMES TRAP POLLUTANTS
Energy-efficient homes have a dark side:
- Sealed tightly to save energy = poor air exchange
- Off-gassing from new building materials
- HVAC systems recirculate contaminated air
- Humidity control issues in sealed environments
- Less outdoor air dilution of pollutants
COST-EFFECTIVE PREVENTION
Testing saves money in the long run:
- Prevent costly medical bills and treatments
- Avoid expensive whole-home remediation
- Target improvements where needed most
- Optimize HVAC efficiency and lifespan
- Maintain or increase property value
PEACE OF MIND
Know exactly what you're breathing:
- Objective data from certified laboratories
- Identify problem sources you can fix
- Verify effectiveness of improvements
- Sleep better knowing your home is safe
- Make informed decisions about your health

Multi-pollutant testing that gives you the complete picture of your indoor air
MOLD SPORE ANALYSIS
What we test:
- Airborne mold spore counts
- Identification of mold species
- Indoor vs. outdoor comparison
- Toxigenic mold detection (black mold, etc.)
- Concentration levels and health risk
Why it matters: Mold exposure causes allergies, asthma, and respiratory infections. Some species produce toxic mycotoxins. Learn about black mold in St. Louis homes.
VOC SCREENING (VOLATILE ORGANIC COMPOUNDS)
What we test:
- Formaldehyde from furniture and flooring
- Benzene from gasoline, paint, plastics
- Toluene from adhesives and solvents
- Xylene from paints and varnishes
- Total VOC (TVOC) levels
Why it matters: VOCs cause headaches, dizziness, respiratory irritation, and long-term health effects. New construction and renovations significantly increase VOC levels.
ALLERGEN TESTING
What we test:
- Pollen (tree, grass, weed varieties)
- Dust mite allergens
- Pet dander (cat, dog, rodent)
- Cockroach allergens
- Skin cell particles
Why it matters: Allergen exposure triggers asthma attacks, allergic reactions, and chronic respiratory issues. Particularly important for children and asthma sufferers.
PARTICULATE MATTER ANALYSIS
What we test:
- PM2.5 (fine particles from cooking, smoke)
- PM10 (larger dust and pollen particles)
- Ultrafine particles from combustion
- Airborne dust concentration
- Particle source identification
Why it matters: Fine particles penetrate deep into lungs and bloodstream, causing cardiovascular and respiratory disease. PM2.5 linked to increased mortality risk.
CARBON DIOXIDE & MONOXIDE
What we test:
- CO2 levels (ventilation indicator)
- Carbon monoxide detection
- Continuous monitoring capability
- Peak concentration tracking
- Combustion appliance assessment
Why it matters: High CO2 indicates poor ventilation. Carbon monoxide is deadly - the "silent killer" from faulty furnaces, water heaters, and gas appliances.
RADON TESTING (OPTIONAL ADD-ON)
What we test:
- Short-term radon concentration
- Long-term monitoring available
- EPA-approved testing methods
- Basement and living area levels
- Mitigation recommendations
Why it matters: Radon is the #2 cause of lung cancer after smoking. Missouri has elevated radon levels. EPA recommends all homes be tested.
TEMPERATURE & HUMIDITY MONITORING
What we test:
- Relative humidity levels
- Temperature variations by room
- Dew point calculations
- Comfort and mold risk assessment
- HVAC performance evaluation
Why it matters: High humidity promotes mold growth and dust mites. Low humidity causes respiratory irritation. Proper levels essential for health and comfort.
HVAC SYSTEM ASSESSMENT
What we test:
- Ductwork contamination
- Air filter efficiency
- Airflow and ventilation rates
- Supply vs. return air quality
- System cleanliness and maintenance needs
Why it matters: Your HVAC system circulates air throughout your home. Contaminated systems spread pollutants to every room, making problems worse.
ST. LOUIS AIR QUALITY CHALLENGES
Why St. Louis homes face unique indoor air quality issues
HIGH HUMIDITY CLIMATE
St. Louis summers average 70-80% humidity. This moisture-rich air infiltrates homes, promoting:
- Mold and mildew growth
- Dust mite population explosions
- Musty odors from dampness
- Condensation and moisture damage
SEVERE SEASONAL ALLERGIES
Missouri ranks among the worst states for pollen allergies:
- Spring: Oak, elm, maple tree pollen
- Summer: Grass and weed pollen
- Fall: Ragweed is particularly severe
- Outdoor pollen infiltrates homes
INDUSTRIAL & URBAN POLLUTION
St. Louis has air quality concerns from:
- Highway traffic (I-64, I-70, I-55, I-44)
- Industrial emissions from river corridor
- Ozone and particulate matter warnings
- Coal and gas-fired power plants
OLDER HOUSING STOCK
60%+ of St. Louis homes built before 1960:
- Inadequate ventilation systems
- Aging HVAC equipment
- Poor insulation and air sealing
- Lead dust concerns in older homes
WINTER HEATING SEASON
Cold weather creates indoor air quality problems:
- Homes sealed tight, reducing air exchange
- Gas furnaces and water heaters produce combustion byproducts
- Space heaters create indoor pollution
- Fireplace use adds particulates
BASEMENT & CRAWL SPACE ISSUES
St. Louis clay soil and humidity create basement problems:
- Chronic dampness and musty odors
- Radon entry through foundation cracks
- Poor air exchange with living areas

WHAT ST. LOUIS FAMILIES SAY
"My daughter's asthma was getting worse and we couldn't figure out why. The air quality test found high mold spore counts AND elevated VOCs from our new carpet. After following their recommendations - new HEPA filter, mold remediation, and better ventilation - her symptoms improved dramatically within 2 weeks. Life-changing."
"We moved into a newly renovated loft downtown and started getting daily headaches. Testing revealed sky-high formaldehyde levels from the new cabinets and flooring. The report gave us ammunition to negotiate with our landlord for air purifiers and increased ventilation. Headaches gone within a month. Worth every cent."
"After having our HVAC cleaned, we wanted to verify air quality improved. The testing showed a 70% reduction in particulate matter and mold spores - objective proof the cleaning worked. We now test annually to track air quality. Peace of mind knowing our kids are breathing clean air."

AIR QUALITY TESTING FAQS
What's the difference between air quality testing and mold testing?
Mold testing focuses specifically on mold spores and moisture issues. Air quality testing is comprehensive - it includes mold but also tests for VOCs, allergens, particulate matter, carbon dioxide/monoxide, and other pollutants. Think of mold testing as a specific concern, and air quality as the complete picture of everything you breathe.
How long does the air quality testing process take?
The on-site inspection takes 2-3 hours. Lab results typically return in 3-5 business days (rush 2-day service available for $150). We'll schedule a follow-up consultation within 1-2 days of receiving lab results to review findings and recommendations.
Do I need to be home during testing?
It's helpful but not required. If you're present, we can discuss your specific concerns and show you potential problem areas. If you can't be home, we can arrange for access through a key or lockbox. We'll discuss findings with you by phone after testing.
How should I prepare for the air quality test?
For most accurate results: 1) Keep your home "as usual" - don't over-clean or ventilate excessively, 2) Avoid running air purifiers for 24 hours before testing, 3) Keep windows/doors closed for 2-3 hours before we arrive, 4) Note any specific areas of concern to test. We want to capture normal conditions.
Will you tell me if my air quality is "good" or "bad"?
Yes - we compare all results to EPA, WHO, and OSHA standards. You'll receive clear ratings for each pollutant: Excellent, Good, Fair, Poor, or Hazardous. We explain health implications at each level and prioritize which issues to address first based on risk.
What if the test finds problems? Will you fix them?
We're testing-only specialists (no conflict of interest). We provide detailed recommendations but don't perform remediation or sell equipment. This ensures objective, unbiased results. We can refer trusted contractors if needed, but you're free to choose anyone.
Is air quality testing worth it if I don't have symptoms?
Absolutely! Many pollutants have long-term health effects before causing immediate symptoms. Testing provides a baseline - you'll know your home is safe, or you can proactively address problems before they impact health. Especially valuable for pregnant women, infants, or new homeowners.
How often should I test my home's air quality?
We recommend testing: 1) When moving into a new home, 2) After renovations or new construction, 3) If family members develop unexplained health issues, 4) Every 2-3 years as preventive maintenance, 5) After major HVAC repairs or changes. Homes with chronic issues may benefit from annual testing.
Do you test for radon?
Yes! Radon testing is available as an add-on ($150) or included in our Premium package. Radon is the #2 cause of lung cancer and common in Missouri basements. EPA recommends all homes be tested. We use EPA-approved short-term (48-hour minimum) testing protocols.
Can air quality testing help with my allergies or asthma?
Definitely! Testing identifies specific triggers in your home - mold spores, dust mite allergens, pet dander, pollen, etc. Once you know what's causing symptoms, you can target solutions (HEPA filters, dehumidifiers, HVAC cleaning) instead of guessing. Many customers see dramatic symptom improvement after following our recommendations.
What equipment do you use for testing?
We use professional-grade equipment: AIHA-approved air sampling pumps, particle counters, VOC analyzers, thermal imaging cameras, moisture meters, and continuous monitoring devices. All samples analyzed by AIHA-accredited laboratories - not consumer-grade test kits.
Why is St. Louis air quality particularly concerning?
St. Louis has a perfect storm of issues: high summer humidity (promotes mold), severe seasonal allergies (pollen infiltrates homes), urban/industrial pollution, older housing stock with poor ventilation, and Missouri's elevated radon levels. These factors combine to create challenging indoor air quality. Read our St. Louis air quality guide.
