Understand mold levels in your home with DNA sequencing
Airborne mold is invisible. Its effects aren't.
DNA testing for mold
Mold spores are microscopic, but their impact isn’t. Boulder Blue's mold testing sequences DNA to precisely identify molds in your home's air so you can stop guessing and take targeted action.
Invisible, but impactful
Mold spores accumulate even in clean homes
Real health effects
Allergies and asthma are often tied to unseen molds
Environments change
Seasons, humidity, pets, and renovations affect mold particles in the air.
Data creates clarity
Lab measurements help target cleaning and remediation efforts.
Who Benefits From Mold Testing?
Whether you’re managing health symptoms, evaluating a property, or hosting guests, allergen data helps you make better indoor environment decisions.
Allergies
"Seasonal" indoor allergies can occur throughout the year as molds enter your home from the outside.
Asthma
Almost 1 in 10 people in the US suffer from asthma. Although asthma can have many triggers, high mold levels can increase symptoms for those that suffer.
Home inspections
Home purchases are some of the most costly decisions we make. Including our mold tests with home inspections provide transparency and smooth transactions for buyers and sellers.
Short-term rental
Providing an Airscore™ along with a short-term rental listing can provide peace-of-mind to renters and help promote properties in a competitive market.

| How It Works | Open agar plate left out to collect settling spores; incubated to grow visible colonies | Swab or tape lifts material from a visible surface and sends to lab for identification | Pump pulls a small volume of air through a cassette; analyzed under a microscope | Active device pulls a large, controlled air volume through a filter; standardized DNA-based analysis |
| What It Detects | Living spores that settle by gravity and can grow on plates | Mold on that specific surface (viable + non-viable depending on method) | Airborne spores (viable + non-viable), categorized by morphology | Airborne mold, spores, allergen-containing particles |
| Accuracy |
⚠ Very Low Non-quantitative, biased by airflow & time |
~ Moderate Confirms surface presence only; not air quality |
~ Moderate Limited by small sample size & microscopy |
✓ High Large air volume + standardized DNA measurement |
| Air Volume Sampled | Moderate | Low | Low | High |
| Analyst Bias Risk | ✗ Yes — high risk | ◑ Some risk | ◑ Some risk | ✓ No — standardized |
| Turnaround Time | 3–7 days (growth + visual read) | 1 week lab processing | 1 week after visit | 1–2 weeks after lab receipt |
| Main Limitations | Misses non-settling spores; prone to false reassurance | Surface-only; not quantitative; limited allergen specificity | Small air snapshot; limited ID power vs. DNA approach | — Designed to minimize limitations of other methods |
| Best For | Cheap visual demonstration that fungal spores exist | Confirming visible mold on a surface | Remediation validation | Homeowners wanting reliable, repeatable air quality insights without hiring an inspector |
Professional-grade air quality insights. No inspector required.
