A free, personalized look at the air inside a family's home.
EezyAir was built by a Colorado dad and healthcare operations leader who spent years tracing his kids' symptoms back to their own house. This page is for advocacy groups, researchers, educators, and writers who want a quick sense of what we do today, where we are, and how we might work together.
Why EezyAir exists
EezyAir was built by a Colorado dad with more than fifteen years in healthcare operations across payer, provider, regulatory, and technology work. That background shaped a preference that runs through everything here: more interested in prevention and root causes than in treating symptoms after the fact.
This isn't a medical guide, and EezyAir doesn't diagnose. It grew out of a family's own search for why their kids kept feeling unwell at home, and what eventually helped turned out to be a layered answer about the house itself. Plenty of families are living through a version of that same story without realizing the house is part of it.
Indoor air isn't one-size-fits-all
The industry often treats it as if it were. Buy this purifier. Replace that filter. Call this remediation company. The honest picture is more specific than that, and usually cheaper to act on if you know where to start.
Three things change almost every recommendation we'd make:
Home age. A 1950s build tends to leak air and carry lead, asbestos, and old plaster issues, but it ventilates itself by accident. A 2015 tight-envelope home keeps conditioned air in and traps everything else along with it: cooking fumes, cleaning chemicals, off-gassing from new materials, elevated CO2. The fixes look almost nothing alike.
Geography. Humid Atlanta pushes mold and dust mites to the top of the list. Denver's altitude and dryness push toward humidification, static dust, and winter combustion byproducts. Coastal homes deal with salt air and persistent moisture. Wildfire-prone regions face smoke intrusion events that make filtration strategy the center of the conversation. Same country, very different air.
Habits. How often windows open, what gets cooked and how, candles and wood stoves, cleaning products under the sink, whether pets sleep in bedrooms, how laundry and bathrooms vent. Habit is often where the biggest no-cost wins live, and it's usually the part generic advice skips entirely.
Once you account for those, most families land on a short list of no-cost or low-cost moves that matter more than any single product purchase. Opening a bathroom fan longer. Running a range hood every time the stove is on. Raising or lowering humidity by a few points. Swapping a cleaning product. Fixing a dry drain trap. A smaller number of situations genuinely need equipment or a professional, and the assessment tries to tell those apart.
What EezyAir does today
EezyAir is a free online assessment that takes about eight minutes. Families answer questions about home age, climate and location, materials, moisture, ventilation, cleaning products, combustion sources, pets, and daily habits. They get back a plain-language read on what's most likely affecting their indoor air, along with practical next steps they can take without buying anything.
Results are free. To help keep the lights on, some of the recommendations link to affiliate products a family might find useful (air monitors, vacuums, filters). Families are free to ignore them. For anyone who wants deeper help, there's an optional expert review under $150 with a trained reviewer who walks through their specific situation. That paid service is not the goal of the tool. The free output is.
Who typically comes to EezyAir
Most families who take the assessment arrive with one of a few concerns. Partners often recognize their own audience in these patterns.
Congestion and allergies
Recurring sniffles, sinus pressure, or nighttime coughing that doctors haven't fully explained.
Headaches and fatigue
Low-grade headaches, brain fog, or tiredness that seems to ease when people leave the house.
Smells and odors
A musty corner, a chemical note after cleaning, or a smell families can't quite place.
A healthier home, no symptoms yet
New parents, buyers of older homes, and anyone who wants a baseline before something shows up.
What the assessment looks at
The questions cover five areas that together account for most indoor air complaints in US homes.
Airflow and ventilation
How fresh air gets in, how stale air gets out, and where the house traps what it shouldn't.
Allergens
Dust, dander, pollen intrusion, and the reservoirs that keep them cycling through the air.
Chemicals and VOCs
Cleaners, fragrances, paints, new furnishings, and other off-gassing sources families often miss.
Mold and moisture
Humidity, past leaks, hidden reservoirs, and the warm-damp conditions that let mold grow.
HVAC integrity
Filter quality, duct condition, combustion appliances, and how the mechanical system is helping or hurting.
Where we are today
We're early. A few hundred households have taken the assessment so far. We're working toward a lot more. That honest starting point is part of why partnerships matter at this stage: they help the families who'd benefit from the tool actually find it.
The longer intent: education, not targeting
Every family who goes through the assessment gets useful answers today. That's the first layer, and it matters now. Families who need more help right away can opt into the expert review. Everyone else walks away with information they can act on the same afternoon.
The longer game is a database the research literature is missing. What's actually inside US homes, and how it connects to the symptoms families report, is surprisingly under-documented. The closest large effort we've found is the RIOPA project from the early 2000s, which measured indoor, outdoor, and personal air exposures in 310 non-smoking households across Elizabeth NJ, Houston, and Los Angeles. Nothing at consumer-sourced scale has followed.
Our intent with that dataset is explicit: education, not targeting. Aggregate, de-identified findings to help families, researchers, educators, and policy groups understand indoor air better. The data isn't sold, and individual families aren't marketed to on the basis of their answers. Opt-in and reversible either way.
A short read on US indoor air research
A handful of US-focused studies shape most of what's known about indoor air and family health. None is the whole story, and several are now decades old. Together they show both what's been measured and where the gaps still are. Selected for relevance to US households; all links point to PubMed.
The National Human Activity Pattern Survey (NHAPS)
The foundational EPA-sponsored telephone survey of roughly 9,400 Americans. Respondents reported spending an average of 87 percent of their time inside buildings and another 6 percent inside vehicles. This is the source of the widely cited figure that Americans spend nearly all of their lives breathing indoor air.
Relationships of Indoor, Outdoor, and Personal Air (RIOPA)
Still the largest US study of its kind. Simultaneous 48-hour indoor, outdoor, and personal air samples were collected in 310 non-smoking households across three climates: Elizabeth NJ, Houston, and Los Angeles. The central finding was that for many common VOCs and carbonyls, indoor sources drove what families actually breathed, even in homes near outdoor pollution sources. Methods are detailed in a 2005 companion paper.
Meta-analyses of respiratory effects of home dampness and mold
Building on the Institute of Medicine's 2004 review, this Lawrence Berkeley National Laboratory meta-analysis found that dampness and visible mold in homes were associated with roughly 30 to 50 percent higher odds of a range of respiratory and asthma-related outcomes. It's one of the clearest quantitative summaries of home moisture as a health factor.
Public health and economic impact of dampness and mold
A companion analysis (EPA and LBNL) applying the meta-analysis above to national asthma figures. The authors estimated that about 21 percent of current US asthma cases were attributable to home dampness and mold, implying roughly $3.5 billion in annual asthma costs tied to housing moisture alone. The figures are dated and conservative by current methods, but they remain the most cited US numbers on the topic.
Population attributable fraction of gas stoves and childhood asthma
This US-focused analysis estimated that about 12.7 percent of current childhood asthma in the United States is attributable to gas stove use, with higher state-level estimates in places where gas cooking is more common. The paper is peer-reviewed and widely cited, and its methodology (extrapolating a meta-analytic odds ratio to the population level) has been debated. We include it because it reflects where a lot of current US conversation about combustion indoors is happening, not because it settles the question.
Evaporative coolers and wildfire smoke exposure
A recent community-engaged study in California's San Joaquin Valley illustrating how geography and building type interact. Evaporative ("swamp") coolers, common in hot-dry regions and in lower-income homes, pull unfiltered outdoor air indoors. During wildfire events, that directly piped smoke into living spaces. A useful reminder that the right indoor-air strategy depends heavily on what kind of home you live in and where.

Common questions
Is EezyAir medical advice?
No. EezyAir is an environmental assessment of a family's home. It doesn't diagnose conditions, prescribe, or replace a clinician's judgment. We recommend families share anything notable from their results with their own doctor, and we don't collect medical records.
How should reporters and researchers describe what you are today?
A free, consumer-facing indoor air assessment built by a small team in Colorado, in early growth. A few hundred households to date. An optional expert-review upgrade is available for families who want more help. Our dataset isn't yet at a scale where aggregate findings are publishable.
How is the data used?
Personal identifiers are never sold. Participation in aggregated, de-identified research is opt-in and reversible. Any aggregate findings shared with partners or researchers are at a level where individual households can't be identified. The privacy policy spells out the specifics.
Can partners and media reference EezyAir findings?
Today, mostly directionally. As the dataset grows we plan to publish aggregate summaries partners can cite. If you're working on a specific story, brief, or report and think our angle fits, email us and we'll tell you honestly what we can and can't support with data yet.
What does the optional expert review include?
A US-based trained reviewer walks through the family's specific assessment, reviews photos or additional information they provide, and answers follow-up questions. Under $150. It's for families who want a second set of eyes or have a more complicated situation. It's not a required step, and most families act on the free output alone.
Is this really a funnel to sell air purifiers?
Fair question. Results often include recommendations that cost nothing: run the range hood, open a bathroom fan longer, fix a dry drain trap, swap a cleaning product. Some recommendations link to affiliate products a family might find useful (monitors, vacuums, filters), which helps cover hosting and development. Families are recommended to start with free solutions and are guided toward helpful selections with products or professionals may be more appropriate. One easily identifiable example is mold. Limiting recommendations to ventilation would be a health and safety risk so we provide guidance on selecting appropriate professionals but are not compensated by any company.
