Pollen Sense in action

Consider these real-world scenarios and how our data provides clear answers.

Factory Owner

A factory owner concerned with employee health needed to know if poor air quality was putting his team’s health and productivity at risk.

Data was collected in his shop

Within 30-60 minutes, airborne particles were sampled, identified, and tagged

He had no idea how bad it was

After seeing the data, he upgraded the ventilation and filtration — enabling the workers to breathe easy and improve safety, morale, and compliance.

Extreme Allergy Sufferer

An allergy sufferer could not go outdoors during high pollen days. Data on allergy and weather sites was insufficient to tell him if it was safe to venture out.

Data was collected across multiple community sites

Within 30-60 minutes, particles were sampled, identified, tagged, uploaded to the cloud, and updated in the app

Armed with real-time data, he finally drove with the windows down — and was able to breathe easy for the first time in years.

Public Health Researcher

A researcher studying the impact of airborne pollutants in underserved neighborhoods needed real-time, location-specific data to validate trends and inform policy decisions.

Data was collected across multiple community sites

Within 30-60 minutes, particles were sampled, identified, tagged, and uploaded to the cloud

The data told a story no one else could see

Now backed by real-time, accurate data she could breathe easy, being prepared to guide accurate policy decisions and air interventions.

Concerned Mother

A mother recently had mold removed from her home — but her kids hadn’t fully recovered yet... She needed to know if the air was truly clean and safe to breathe.

The sensor was deployed and data collected directly in her home

Data was sampled, identified, and tagged after multi-room 15 minute sessions

Seeing is believing!

The results confirmed that the air was clean, and her kids were no longer at risk.With peace of mind that no other test could provide, she could breathe easy — literally.

Take a DEEP breath

What if the air you breathe is filled with invisible threats — like pollen, mold, dust, smoke, and even microplastics — that can make you sick for weeks?

400M+ People suffer from airborne allergies

400m+ people suffer from airborne allergies, with more each year due to climate change, urbanization, and extreme weather.

apx. 47% of U.S. buildings have mold

Indoor air can be 2–5× more polluted than outdoor air — often due to mold, which can trigger asthma, fatigue, and illness.

1.6B people work in polluted air every day

From outdoor job sites to indoor facilities, air pollution causes 860,000  premature deaths per year.

Outdated air data can’t protect us

Most air reports rely on manual sampling and lab work — often taking 2–3 days to deliver results, long after people have already been exposed.

We built the solution.

The world's first real-time, portable, particle identification sensor.

Made to detect and identify what's in the air right now, where you are.

Deployed worldwide to give deep coverage and accurate data.

Deep, robust data to help make informed decisions
