Our story.

Winston Mok, a former Google product manager, founded Woosh in the wake of the 2018 California wildfires and the surge in remote work during the COVID-19 pandemic. These events underscored the critical issue of indoor air quality maintenance at home. In response to this need for accessible air filtration, Mok and his team leveraged 3D printing to design Woosh's initial air filter. Dissatisfied with conventional filters, they embarked on the creation of an intelligent solution that actively monitors air quality and delivers real-time insights through a mobile app. This innovation ensures that everyone can enjoy the benefits of optimal indoor air quality in their homes.


We're shipping.

2023 has been an exciting year for Woosh. From finalizing our product to establishing industry partnerships and moving into our first office to shipping product!

We're ramping up production and continuing to make improvements to our mobile app, 3rd party software integrations and data analytics.

We excited to see the growing number of users onboarded and seeing the value that Woosh brings to their home. From air quality monitoring to taking the guesswork out of knowing when to change their air filters.

Cheers to cleaner air for everyone!

Woosh appeared on Shark Tank.

Winston Mok appeared on ABC's Season 14, Episode 4 of Shark Tank with his innovative product Woosh, pitching the smart air filters that turn your HVAC system into an air purifier.

"Born out of the wildfires in California, Woosh makes the smartest, most effective air filter. It's made from best-in-class filter materials and has sensors that measure air quality, flow and usage. Filter replacements are sent automatically when it's time to change. With Woosh you don't have to worry about your air!"

Podcast: Is Kickstarter still relevant for smart devices?

This week’s guest is Winston Mok, the founder and product lead of Woosh Air, a company making a connected air filter. We talk about how Woosh works, its focus on sustainability, and how it plans to integrate within existing smart home services. We also talk about Mok’s decision to use Kickstarter to launch the connected air filter, a decision that would have been a no brainer back in 2014, but seems almost quaint now. Mok explains why he thinks Kickstarter was a good option for Woosh and shares some of the benefits he got from launching on the platform. He also discusses how it it helped prepare for manufacturing at scale amidst the chip shortage, and shared advice on dealing with that situation. It’s a really useful interview.

Research & Development.

Throughout our journey we have continually invested in a strong technical foundation for our product design and methods. In order to iterate on designs, we've had to develop custom equipment and processes to give quick cycles of learnings & Insights. Additionally we've leaned on our partners who have provided invaluable support and guidance to help us produce the best product possible.

Here's a photo of dust testing where we load up our filters with certified dust in order to similar years of accumulation. We nicknamed this test 'The Big Dirty'!

Heads down. Prototyping.

Unique circumstances breed unique opportunities. In this case, Covid shelter-in-place was a time to focus and innovate.

Every months goal was to create a new prototype that was an improvement on the previous month. Rinse and repeat month after month until it worked.

See our Instagram for photos of numerous prototypes along the way:


Sept 2019

The idea of Woosh emerged.

Woosh was founded after the 2019 forest fires in California. The lack of air filters and the need for clean air drove the desire for a better solution. In true startup style, the first Woosh products were made from air filters and fans in a California garage.

With a small army of 3D printers and a team of dedicated innovators, Woosh quickly made a splash into the world of HVAC. Traditional cardboard filter designs aren’t convenient to ship, lack smartness and connectivity, and could be more sustainable.

After numerous interviews with homeowners and countless prototypes, we knew we were on to something.
