Woosh Smart Air Filter Update | Shark Tank Season 14

Traditional HVAC filters were inefficient at maintaining air quality, often failing to capture harmful particles like bacteria and viruses. Frequent replacements led to waste, while delayed changes risked air pollution and system damage. This led Winston Mok to create Woosh, which provides a smarter solution with its MERV-13-rated filters and real-time air quality monitoring via a mobile app, ensuring cleaner air and more efficient usage. Will Winston’s idea get the support of the sharks? Let’s dive into our Woosh update and pitch recap to find out.

If you’re short on time, here’s a quick overview of what happened to Woosh after Shark Tank.

Winston pitched his smart air filters, Woosh, on Shark Tank Season 14, seeking $500,000 for 10% equity. He secured a deal with Kevin O’Leary for $500,000 for 10% equity + $0.50 cent royalty per unit in perpetuity.

In terms of a Woosh update, the company secured funding in an early-stage venture capital investment. Further, they also partnered with 3M and Copeland’s Sensi, leveraging these collaborations to enhance its technology.

Shark Tank Woosh Pitch

• Entrepreneur: Winston Mok
• Business: Smart Air Filters 
• Ask: $500,000 for 10% equity
• Result: $500,000 for 10% equity + $0.50 royalty
• Shark: Kevin O’Leary  

Winston entered Shark Tank with Woosh, a smart air filter designed to improve indoor air quality while simplifying maintenance.

He sought an investment to help scale production and enhance the app’s features for real-time air quality monitoring.

Woosh combines innovative design and advanced technology to address common issues with traditional HVAC filters.

It offers a reusable frame and foldable, disposable filters rated MERV-13.

These filters capture over 50% of harmful particles, including viruses and bacteria like COVID-19.

The system stands out by integrating sensors and WiFi connectivity.

This allows it to monitor air quality in real-time, transmitting data to the Woosh App, where users can track air quality, receive alerts, and effortlessly manage filter replacements.

Unlike traditional filters that require frequent manual checks, Woosh automates maintenance.

For instance, when air quality drops, the system sends an alert and activates the filtration process until the air is clean.

Moreover, the app tracks the filter’s life span and automatically reorders replacements.

During the pitch, Kevin O’Leary asked about sales numbers. Winston admitted that the company was pre-revenue, which drew groans and skepticism from the sharks.

The sharks questioned how he justified his valuation.

Winston attempted to alleviate their concerns by sharing that he had recently raised $62,817 through a Kickstarter campaign and was developing a partnership with Emerson.

This partnership aimed to pair Woosh with a product similar to a smart thermostat.

Daymond John inquired about pricing, and Winston explained that the reusable filter frame would sell for $99 while replacement filters would cost $20.

He added that he was in discussions with large filter manufacturers about licensing agreements, a detail that intrigued Kevin.

However, when Robert Herjavec asked about the value proposition, Winston highlighted its ability to monitor air quality and notify users when the filter needed changing.

Robert remained unconvinced, noting that replacing traditional filters is already straightforward. Finding no compelling reason to invest, he exited the negotiations.

Daymond also declined to make an offer, stating that he didn’t see how he could add value to the business.

Similarly, Lori Greiner raised concerns about the patents, explaining that the lack of clarity made it difficult to gauge their potential. She chose to step away.

Mark Cuban expressed reservations about the marketing costs likely required to establish Woosh in the market and decided to bow out as well.

Kevin, however, saw potential and offered $500,000 for 10% equity, with an additional $0.50 royalty per unit sold in perpetuity.

He later revised his offer, increasing his equity ask to 15%.

Winston countered by proposing $500,000 for 10% equity without the royalty.

After a round of negotiations, they both agreed to Kevin’s initial offer and struck a deal.

Now, let’s get a Woosh update to see how the company has progressed since its appearance on Shark Tank.

Shark Tank Woosh Update 

Our Woosh update found that the deal with Kevin O’Leary did not close, reportedly due to disagreements over terms during due diligence.

In December 2023 when the company announced a partnership with 3M, with the plan to integrate 3M’s filtration technology into its smart air filters.

Additionally, Woosh collaborated with Copeland’s Sensi in a bid to enhance its smart thermostat integration.

Woosh raised $2.27 million in early-stage venture capital funding in July 2023, indicating investor confidence in its growth potential.

At the time of this writing, our Woosh update found that the company has grown to over $1 million in annual revenue.

Despite all the odds against Winston, we’re calling this Woosh update a success.
