Live Indoor Air Data — U.S. Office Average

The air you

can't see

is the problem.

"This is the air inside an average American office right now."

Breathe traces particulate counts, volatile organic compounds, and CO₂ curves through the rooms where people spend ninety percent of their lives.

Timeline Progression

A building's air quality story

From construction off-gassing on Day 1 to remediated clarity at Month 12 — every scroll advances the story.

Day 1

Construction Off-Gassing

The invisible aftermath of renovation

Fresh paint, adhesives, new carpet, and sealants release a cocktail of VOCs at concentrations 5–10× higher than outdoor air. PM2.5 from drywall dust lingers for weeks. Formaldehyde from pressed-wood furniture peaks here.

Occupancy Spike

People arrive and so does the problem

CO₂ climbs as occupancy increases. Cleaning chemicals add a second VOC layer. HVAC systems recirculate contaminants rather than diluting them. Sick days begin to cluster — facility managers notice but can't explain.

Assessment & Intervention

Breathe maps every invisible variable

A Breathe assessment deploys calibrated sensors across all zones, runs a 72-hour continuous log, and cross-references against ASHRAE 62.1 and EPA IAQ guidelines. The report identifies sources, quantifies exposure, and prescribes targeted interventions.

Remediated Clarity

What clean actually feels like

MERV-13 filtration, targeted ventilation upgrades, and VOC source elimination bring all readings to or below EPA recommended thresholds. The building earns a Breathe Certified Air Quality rating. Sick days drop 31%. Cognitive performance scores improve.

What We Measure

Every invisible variable,
made legible.

Breathe deploys calibrated sensor arrays covering all major indoor air quality parameters — not just the ones that are easy to sell.

Particulate Matter

PM2.5 & PM10

◉

Fine particles from construction dust, cooking, printer toner, and outdoor infiltration. At 12 μg/m³ or above, cardiovascular and respiratory risk increases measurably.

Typical indoor level78% above safe threshold
Construction dustToner cartridgesCookingOutdoor infiltration

Volatile Organic Compounds

VOCs

◈

Benzene, formaldehyde, toluene — emitted by paints, adhesives, furniture, and cleaning products. The WHO classifies formaldehyde as a Group 1 carcinogen.

Typical indoor level65% above safe threshold
Paint & varnishAdhesivesNew furnitureCleaning products

Carbon Dioxide

CO₂

◇

Above 1,000 ppm, cognitive performance measurably declines. Most offices hit 1,400–1,800 ppm by mid-afternoon with standard HVAC.

Typical indoor level55% above safe threshold
Occupant respirationInsufficient ventilationHVAC recirculation

Thermal Comfort

Humidity & Temperature

◌

Below 30% RH, respiratory passages dry and viral transmission increases. Above 60%, mold spore counts climb within 48 hours.

HVAC imbalanceSeasonal variationBuilding envelope

Specialty Contaminants

Radon & Biologicals

◎

Radon is the second leading cause of lung cancer in the US. Mold spores and bacteria require separate bioaerosol sampling — standard HVAC filters don't catch them.

Every assessment includes a 72-hour continuous monitoring period — not a single spot-check. Air quality fluctuates dramatically by time of day, occupancy pattern, and HVAC cycle. We capture the full picture.

We had 23% above-baseline sick days for eight months. Three HVAC companies found nothing. Breathe's sensor array identified a formaldehyde source in the east-wing renovation within the first 24 hours. Four weeks after remediation, sick days normalized.

Our daughter's asthma worsened after we renovated the basement. Pediatrician found nothing clinically. Breathe measured VOC levels 4× the EPA recommended maximum from the new epoxy floor coating. The fix cost $600. Her symptoms resolved within two weeks.

Pre-occupancy certification used to be a 6-week process with three separate consultants. Breathe handled the full IAQ certification for our 340,000 sq ft mixed-use development in 11 days. Tenants signed faster knowing the data was there.
