Woosh went on Shark Tank to fix a product nobody thinks about until allergy season: the disposable cardboard furnace filter. Founder Winston Mok pitched a smart, reusable air filter system in Season 14, got Kevin O'Leary to say yes on air, and then watched the deal evaporate in due diligence. The company kept building anyway, and by 2026 it has quietly turned air filters into a subscription-style business.

The Short Answer

Yes, Woosh is operating. Its store at wooshair.com is active, with the core system sold as starter kits from about 40 dollars in furnace sizes from 12 by 24 inches up to 20 by 30 inches. The pitch is a rigid, reusable frame with integrated magnets and custom gaskets that replaces the flimsy cardboard filter your HVAC system was designed around, paired with low-cost MERV 8 and MERV 13 refills.

The product family has grown beyond the original filter frame into smart add-ons, including a sensor module, an air quality monitor, and thermostat integration, and the company backs orders with free shipping and a 30 day trial. The blog is current, which is often the first thing to go dark when a startup is winding down.

The Shark Tank Pitch

Mok appeared in Season 14, Episode 4, which aired in October 2022. His argument was that HVAC filters are the single most neglected part of home air quality. People forget to change them, buy the wrong sizes, and let clogged filters strain their systems, so Woosh built a filter that seals better, monitors itself, and tells you when it needs attention.

He asked the panel for 500,000 dollars against 10 percent, a 5 million dollar price tag. Several sharks worried the product was early and the hardware path expensive, the classic objections to any smart home gadget.

The Deal That Got Done

Kevin O'Leary was the buyer, and the negotiation was pure Mr. Wonderful. He opened at 500,000 dollars for 15 percent plus a 50 cent per unit royalty in perpetuity. Mok countered by holding equity at 10 percent while accepting the royalty, and O'Leary agreed, taking 10 percent for the full check with 50 cents a unit riding along forever.

The arrangement never made it past the closing table. Multiple outlets that followed up on the company, including House Digest and BGR, report that the O'Leary investment fell through during due diligence. Woosh went forward without shark capital, and in July 2023 it raised about 2.27 million dollars in early stage venture funding instead, a bigger check than the one it lost.

Building the Boring Subscription

The business model is the quietly clever part. A reusable frame turns a commodity purchase into a recurring relationship, because once the frame is on your return vent, the refills come from Woosh. Tracking coverage reported the company passed 1 million dollars in annual revenue by December 2024 and expanded the line in early 2025 with the standalone air monitor and a fold flat filter.

Woosh has also marketed city by city, with launches reported in Sacramento, Dallas, Austin, Boston, Chicago, Philadelphia, and Toronto. Even its blog leans practical rather than promotional, with troubleshooting guides on clogged filters and a case study about a McDonald's franchise using the system, which points at a commercial customer base alongside homeowners.

Woosh net worth in 2026

No credible current valuation exists for Woosh. The knowable data points are the 5 million dollar price the on-air terms put on it, the 2.27 million dollar venture round from mid 2023, and the reported crossing of 1 million dollars in annual revenue in late 2024.

A hardware startup with venture backing and growing recurring refill revenue is likely worth more than that Tank-floor number today, though nothing proves it publicly. The company publishes no financials, and any specific 2026 figure would be invented.

Where Things Stand Now

Woosh pitched in Season 14, shook hands with Kevin O'Leary on a 10 percent stake plus a royalty, lost the deal in diligence, and replaced it with venture funding and steady product releases.

As of 2026 the answer is a clean yes. The store is live, the refills keep the revenue recurring, and the smart filter that the sharks called early is still on the market while the cardboard competition stays exactly as dumb as it always was.
