How it works


Wynd keeps your personal space free from particulates including allergens, germs, and industrial pollution (PM2.5).



Despite its small form factor, Wynd can deliver over 8 liters of clean air per second.


The airflow design

Wynd engineering lead Eric Munoz is a former aerospace engineer who worked on the design of jet and rocket turbine blades before joining the team. He used his airflow expertise to craft Wynd’s patent-pending fluid dynamics.

Wynd includes a low-turbulence, high-airflow system that keeps the device small while enabling it to clean a high volume of air—all without getting too noisy.


The filter

Wynd contains a medical-grade air filter capable of capturing particles as small as 0.3um (1 / 210th the average thickness of human hair).

The filter is lined with an antimicrobial layer lined with silver. This keeps it clean from microbes such as bacteria and mold. As air passes through this filter, the particulate pollutants are removed and any residual germs are killed off, and purified air flows out into your environment.

The filter typically lasts for 3 months, depending on your environment's pollution level.

But don't worry about having to calculate it—we do it for you. We can tell you how used up the filter is and alert you when it’s time to order a replacement.


Smallest particulate sensor on the market

We spent 18 months developing our own patent-pending, particulate matter sensor because everything on the market was too big—and too inaccurate.

We created the smallest commercial particulate sensor in the world.

The Wynd Air Quality Tracker is highly accurate: It’s comparable to much more expensive (and larger) sensors. And, many of those large and expensive sensors stop working over time because grime and pollutants throw off their mechanisms. To avoid this, we engineered the tracker to remain highly accurate over time through dynamic calibration and an internal design that protects sensitive components from accumulating dust.

The Tracker has a very high correlation (0.99) with high-end lab-grade, professional air quality sensors. The chart below shows a test we conducted of the Wynd Air Quality Tracker prototype vs. a lab-grade sensor, and yields a correlation of 0.99 (the highest is 1.00):



Although we built Wynd to purify the air in your personal space, we decided to see how well it could clean a small room. So we had it tested in a 640-cubic-foot chamber (comparable to an 8x10ft room) by Research Triangle Institute, a leading national research institute and filtration testing laboratory.
