Is Hydroviv Still in Business? (2026 Update)
Is Hydroviv from Shark Tank still around in 2026? The deal it made, the sharks who invested, and where to buy Hydroviv today.
Most water filter pitches sound the same. Hydroviv stood out because it did not try to sell one filter for everyone. Instead, founder Eric Roy, a scientist, built a system that analyzes the specific water quality in your area and customizes the filter to target the contaminants actually in your tap, from lead to PFAS to arsenic. It was a smart, data-driven angle. So in 2026, is Hydroviv still flowing?
The Short Answer
Yes. Hydroviv is very much in business in 2026, and it has done more than just survive. The company was acquired by Culligan International, one of the biggest names in water treatment, and Eric Roy stayed on as Chief Scientist to keep overseeing product development.
Hydroviv filters are still sold, still customized to local water data, and now backed by the resources of a global industry leader.
The Pitch and the Deal
Hydroviv appeared in Season 10, Episode 19. Eric Roy asked for $400,000 in exchange for 10 percent of the company.
Mark Cuban, who has a clear soft spot for science-led founders, made the deal. He offered $400,000 for 20 percent, double the equity Roy had hoped to give up, and the two shook on it.
As with many Shark Tank handshakes, the on-air agreement did not ultimately close in its original form once due diligence began. What mattered far more was the momentum the appearance gave the brand and the credibility of pairing a science-first product with national attention.
Where Hydroviv Is Now
After the show, Hydroviv kept growing on the strength of its core idea: filtration tuned to your zip code rather than a generic one-size-fits-all cartridge. The company expanded beyond its flagship under-sink filter into shower filters and refrigerator line filters, each customized using local water quality data.
That growth eventually caught the attention of Culligan International, which acquired the company. The acquisition gave Hydroviv real scale while keeping Roy involved on the science side, a combination that is rare and reassuring for a contaminant-focused brand.
Buying is easy. Hydroviv sells its under-sink, shower, and fridge filters directly through its own website, where you enter your location so the system can recommend the right setup for your water.
The Bottom Line
Hydroviv is one of the clearer success stories from its season. A scientist with a genuinely different approach got national exposure, kept innovating, and ended up being bought by a major water treatment company while staying true to the data-driven mission that made the product interesting in the first place.
If you care about what is actually in your tap water, head to the official Hydroviv website, enter your address, and let the brand build a filter around your specific water rather than guessing.
