See the invisible

Halo can detect airborne substances that you can't see or smell, enabling you to know what you're breathing.

Add brains to brawn

Halo is the ultimate air quality control center. With smart home integrations, Halo coordinates your home's air purifiers for optimal air filtration. 

Data at a glance

Through our best-in-class app, you can view what your Halo is sensing and control the device no matter where you are. 

Designed to evolve

As our algorithms and feature sets improve, we'll send out remote upgrades to make your Halo even smarter.

Ever wonder what you're breathing?

You scrutinize nutrition lists, filter your water, and review fabric labels...what about your air? The average person take 20,000 breaths a day, so what exactly are you putting into your lungs? Well, just ask Halo - it analyzes the air and gives you a summary of your environment, allowing you to see the invisible.

Make your smart home even smarter.

With IOT integrations for Honeywell Home and Alexa, Halo gives you complete control of your home's air quality.

Insights in the palm of your hand.

Remotely monitor your air quality, control your Wynd devices, and observe air quality trends for optimal health and comfort.

Extract meaning from raw data.

Most air quality sensors just measure the general concentration of particles, but can’t tell you what’s actually there. With Air ID, Halo can tell you exactly what's in the air, and identify whether it's pollen, forest fire smoke, or smog. (Feature coming soon)

The dynamic duo of air quality

Optimized for you

When Halo is near you, the purifier will optimize its cleaning for where YOU are.

Save on energy costs

Since the purifier only turns up when the Halo triggers it, it's super energy efficient.

No need to manually control it

Halo tells the purifier when it needs to turn up and down. Just sit back, relax, and breathe easy.

Odorless toxins are cleaned up

Halo can detect substances that you can't smell - and the purifier automatically removes them

Each Wynd device comes with a 100-day money back guarantee. No risk, no worry, no hassle.
