Woosh Air Shark Tank Update: Net Worth, Products, and Business Status

Woosh Air is a modern technology company that changes how standard home heating and cooling systems handle indoor air quality.

Instead of using basic cardboard filters that get easily clogged and forgotten, the company offers a smart, data-driven air purification system.

This product is designed to slide right into a standard heating, ventilation, and air conditioning (HVAC) unit, instantly upgrading the entire home into a clean air zone.

The complete Woosh system includes three main parts: a Smart Filter, an Air Quality Monitor, and a mobile phone application.

The Smart Filter replaces traditional throwaway filters with a reusable plastic frame. This frame features built-in electronic sensors that actively measure air pressure, temperature, and humidity.

When a normal filter gets dirty, it blocks airflow and makes the HVAC system work much harder. The Woosh sensors detect this exact pressure change. Instead of relying on a random calendar reminder, the system sends an alert to a smartphone only when the filter truly needs to be changed.

The company even offers a subscription service that automatically ships a replacement filter to the front door for $22.

The Air Quality Monitor acts as a standalone sensor that checks the air inside and outside the house. It provides real-time updates to the mobile app.

One of the most powerful features of the Woosh system is how it works with smart home thermostats, such as Copeland’s Sensi, Google Nest, or Ecobee.

If the Air Quality Monitor detects heavy smoke or pollution in the home, it sends a signal to the smart thermostat.

The thermostat then turns on the home’s HVAC fan automatically. This pulls the dirty air through the Woosh filter until the house is clean again.

To capture tiny dirt particles, Woosh uses high-quality Fold Filters with a MERV 13 rating. These filters are built with 3M Filtration Technology.

They are strong enough to trap very small hazards, including dust, pollen, pet dander, mold spores, wildfire smoke, bacteria, and viruses. Because the plastic frame is reusable, the system also cuts down on the amount of cardboard waste that ends up in local landfills.

Woosh Air Founder’s Story and Early Kickstarter Success

Winston Mok is the founder and CEO of Woosh Air. Before starting the company, Mok worked as a Senior Product Manager at Google and earned a degree in Engineering, Computer, and Mechatronics from the University of Waterloo. This strong engineering background helped him understand how to build complex consumer hardware.

The idea for the smart filter came during the massive California wildfires in 2018 and 2019. As thick smoke filled the San Francisco area, the outdoor Air Quality Index shot past 150, making it dangerous to breathe.

Mok tried to buy portable air purifiers, but stores were completely sold out. He also realized that a small room purifier only cleans one single space.

He decided that the best way to protect a family was to use the powerful HVAC fan that already pushed air into every room of the house.

When the COVID-19 pandemic forced millions of Americans to work from home, the need for clean indoor air became even more urgent. Mok identified a few major problems with how Americans treat home air quality.

Most people do not know what is floating in their air, they forget to change their filters, and standard cheap filters do not catch smoke or viruses.

Using a 3D printer in his home, Mok built the first smart filter prototypes. He left his high-paying job at Google to focus on the project full-time.

In early 2022, he launched a Kickstarter campaign that successfully raised $62,817 from hundreds of backers. He also secured $1.3 million in pre-seed funding from tech investors to help get the business off the ground.

Woosh Air Shark Tank Pitch: Season 14 Episode 4

Winston Mok stepped onto the Shark Tank stage in late 2022 during Season 14, Episode 4. He asked the panel of wealthy investors for $500,000 in exchange for a 10% ownership stake in Woosh Air. This request gave his new company a starting valuation of $5 million.

During the pitch, Mok showed the Sharks exactly how the smart frame and sensors worked. To prove that his $5 million valuation made sense, he talked about his successful Kickstarter campaign and shared some massive news.

He revealed a brand-new partnership with Emerson, a massive Fortune 200 HVAC company. Emerson wanted to bundle the Woosh air quality system with its popular Sensi smart thermostats.

Even with this great news, the Sharks were worried. Mok admitted that the company was entirely pre-revenue. They had not shipped any real products to customers yet. Many of the Sharks felt that investing in a company with zero sales was simply too risky, and they backed out.

However, Kevin O’Leary liked the business model. He saw that the company could make steady money by selling replacement filters every few months.

O’Leary offered Mok $500,000, but he wanted 15% equity and a royalty fee of $0.50 for every unit sold.

Mok carefully thought about it and offered a counter-deal. He asked to keep the equity at 10% but agreed to pay the $0.50 royalty. O’Leary accepted, and the two made a deal on television.

A Breakdown of the Shark Tank Offers

Shark Investor	Money Offered	Equity Wanted	Special Terms	Deal Accepted?
Kevin O’Leary	$500,000	15% (Lowered to 10%)	$0.50 royalty per unit	Yes (On TV)
Robert Herjavec	No Offer	N/A	N/A	No
Daymond John	No Offer	N/A	N/A	No
Lori Greiner	No Offer	N/A	N/A	No
Mark Cuban	No Offer	N/A	N/A	No

Did the Deal with Kevin O’Leary Actually Close?

While shaking hands on television makes for great entertainment, business deals take time to finalize in the real world.

During the long paperwork and review process that happens after the show, the deal between Woosh Air and Kevin O’Leary quietly fell apart.

It is very common for Shark Tank agreements to fail before the money changes hands. This can happen due to disagreements over contract details or shifts in how much the company is truly worth.

Even though Mok did not get the $500,000 check from Mr. Wonderful, appearing on national television put Woosh Air in front of millions of buyers. This massive exposure helped the company grow faster than ever.

Woosh Air Post-Shark Tank Growth and Shipping Orders

Without O’Leary’s money, Woosh Air still moved forward and found incredible success. In April 2023, the team finally moved out of a home garage and into a real commercial office space in San Francisco.

Once they had a proper headquarters and a solid supply chain, Woosh officially began shipping real products. They fulfilled all the old orders for the people who supported their Kickstarter campaign, and they opened up regular sales on their website.

The money started pouring in quickly. By December 2024, industry tracking reports showed that Woosh had made over $1 million in annual revenue.

The company also stepped up to help its local community. During severe wildfires in Los Angeles in 2025, Woosh donated 10% of its sales to the California Fire Foundation and offered big discounts to families suffering through the heavy smoke.

Woosh Air Major Partnerships with 3M and Copeland

To make the product even better, Woosh Air teamed up with two massive American corporations.

First, the original partnership with Emerson continued smoothly after Emerson changed its name to Copeland. In late 2023, Copeland announced that its popular Sensi smart thermostats were fully integrated with the Woosh system. This connection allows the two devices to talk to each other seamlessly.

Second, Woosh announced a huge partnership with 3M, a giant in the air filtration industry. By using official 3M Filtration Technology inside the Woosh fold filters, the company guaranteed top-tier performance.

Combining 3M’s trusted filter materials with Woosh’s smart sensors created a product that easily stands out in the crowded home improvement market.

The Current Product Lineup and Pricing

As of today, Woosh Air sells a complete line of air quality gear directly through its official website. Consumers can choose to buy single items or get everything together in a discounted bundle.

The main selling point is still the automated subscription model. Homeowners can sign up to have fresh filters mailed to their house exactly when the app says the old one is dirty.

Technology experts and home reviewers highly recommend the system today. In late 2024, Wired Magazine tested the Woosh filter and gave it a great score of 8 out of 10. The New York Times’ Wirecutter also added Woosh to their trusted list of best home HVAC filters.

Everyday buyers frequently leave five-star reviews, noting that the phone app is simple to use and clearly explains their home’s air data. In one unique case, the Woosh monitor even helped a homeowner discover a broken dryer vent that was leaking bad air into their house.

Competing in the Air Purifier Market

When consumers want clean air, they usually look at popular standalone air purifiers like the Levoit Core 400S, the Blue Pure 211i Max, or the Molekule Air Pro. These machines are great, but they operate very differently than the Woosh system.

A standard room purifier only cleans the air in the single room where it is plugged in. To clean a whole house, a homeowner would have to buy five or six expensive machines and leave them running constantly, which wastes a lot of electricity.

Woosh takes a smarter approach by turning the home’s massive central HVAC unit into a giant air purifier. Since the HVAC fan is already built to push air into every single room, adding a MERV 13 smart filter to that system cleans the entire house all at once. This saves money, uses less power, and avoids cluttering up the living room with bulky plastic towers.

Whole-Home Filter vs. Room Purifier

Feature	Woosh Whole-Home System	Standard Room Purifier (e.g., Levoit, Blueair)
Coverage Area	The entire house (via HVAC vents)	One single room or open space
Floor Space Required	None (Hidden in the HVAC unit)	Takes up space in the living room or bedroom
Maintenance	Replaces filter only when sensors say it is dirty	Usually requires replacing filters every 6 months
Air Quality Tracking	Yes, tracks indoor and outdoor AQI on phone app	Some high-end models track local room air
Noise Level	Hidden away with normal heating/cooling sounds	Fan noise in the room where it is placed

Expanding into Commercial Business Operations

While the company started by selling directly to homeowners, a massive part of its success comes from commercial businesses.

Large buildings like hotels, retail stores, and fast-food restaurants use giant commercial HVAC systems. Usually, maintenance workers climb onto the roof every few months to change the air filters, no matter what.

Sometimes the filters are still clean, which wastes money. Other times, the filters have been clogged for weeks, which damages the expensive air conditioning equipment.

Woosh Air solves this by putting smart filters into commercial buildings. Building managers can now look at a computer screen to see exactly which filters need changing and which ones are fine. This provides several huge benefits to businesses:

• Fast-Food Restaurants: Places like McDonald’s save money because workers do not have to climb dangerous ladders as often to check hidden filters.
• Hotels: Extended-stay hotels using Woosh report far fewer complaints from guests about broken air conditioners or stuffy rooms.
• Laundromats: Coin laundries deal with a massive amount of floating lint. Woosh sensors ensure the machines keep breathing properly without managers having to guess when to clean the vents.

By catching clogged filters early, businesses stop their cooling fans from working too hard. This lowers commercial electricity bills and extends the life of the heavy machinery.

The Growing Crisis of Wildfires and Bad Air Quality

The success of Woosh Air makes perfect sense when looking at the current state of the environment in the United States. Today, the indoor air quality (IAQ) market is exploding, and experts expect it to reach $8.1 billion globally by the end of 2026.

The average American spends about 90% of their life indoors. Because homes trap dust, cleaning chemicals, and pet dander inside, the U.S. Environmental Protection Agency (EPA) now calls indoor air pollution one of the top five health risks in the country.

This problem is getting much worse because of extreme weather and wildfires. Hotter temperatures and long droughts have caused massive, record-breaking wildfires across California, Oregon, Washington, and Colorado. When millions of acres of forest burn, they create thick smoke filled with fine particle pollution, known as PM2.5. This dangerous smoke does not just stay near the fire; the wind carries it thousands of miles across the country, sneaking into homes far away.

The American Lung Association releases a “State of the Air” report every year. Their recent findings show that 46% of all Americans, over 156 million people, live in areas with failing grades for dangerous particle pollution and ozone.

Wildfire smoke is literally erasing decades of clean air progress in the United States. Researchers at Stanford University found that the number of people exposed to unhealthy smoke grew by 27 times over a simple ten-year period.

When the news announces a “Code Purple” or “Code Maroon” hazard day, the air outside is highly toxic. The EPA clearly advises people to stay inside and use top-quality air filters to stay safe.

Because basic cardboard filters do not stop smoke, health officials strongly suggest upgrading to MERV 13 filters. This perfectly positions Woosh Air as a necessary tool for survival and comfort, rather than just a fun smart home gadget.

Is Woosh Air Still in Business?

Yes, Woosh Air is a thriving, active company as of today.

Even though the brand has not posted much on social media sites like Twitter or Instagram recently, the business side is doing incredibly well. CEO Winston Mok stays highly active in the business community.

He frequently attends major tech trade shows like CES and speaks at industrial events like the Reliable Plant Conference. He recently met with teams at SpaceX to discuss air quality technology.

The main website runs smoothly, and the company continues to process and ship orders all across the United States every single day. Their move to help commercial businesses manage giant HVAC units has brought in new streams of income that keep the company incredibly stable.

What Is the Net Worth of Woosh Air Today?

Business reports estimate the net worth of Woosh Air to be between $5 million and $6.65 million.

When Winston Mok walked onto Shark Tank in late 2022, he valued his brand-new company at exactly $5 million. Even without the $500,000 from Kevin O’Leary, the company held its ground. By using the $1.3 million they previously raised from tech investors, they managed to build their products, secure patents, and hit over $1 million in yearly sales.

Thanks to brilliant partnerships with giants like 3M and Copeland, plus a massive push into commercial heating and cooling, Woosh Air has easily proven that its original $5 million valuation was correct. In the end, this smart air filter company goes down in history as one of the great businesses that “got away” from the Sharks.
