AquaRevival achieves 97.3% (1.56-Log) first-pass Crypto removal, exceeding existing regulations

AquaRevival, a company that brings the highest standard of water filtration technology to the attractions industry, has achieved a milestone 1.56-Log NSF 50 Crypto reduction, reflecting the company's engineering leadership and dedication to safer water.

In January last year, the company was awarded the first-ever NSF 50 Crypto certification for any filter in the commercial aquatic space, and achieved a 0.48-Log reduction at 3.0 gpm/sf rating (approximately 67% removal).

At the NSF 50 Joint Committee meeting in September, a position paper was advanced to increase the allowable log reduction for Crypto to 4.0-Log (99.99% removal).

Just ahead of the January 2026 voting, AquaRevival retested its equipment and achieved these numbers.

This reduction is the result of AquaRevival's ongoing innovation. Following its initial certification in January 2025, the company retested in December at NSF's international headquarters and achieved a 1.56-Log reduction at 1.0gpm/sf, surpassing NSF's 1.0-Log reduction capped limit.

During further testing to support the 1.0-Log reduction certification, the observed log reduction of microspheres ranged from 1.564 (97.3% removal) to 2.741 (99.8% removal) with an average reduction across all measurements of 2.233 log (99.2% removal).

"AquaRevival is committed to unleashing higher performance at the same price point within the same filtration envelope resulting in far more value for AquaRevival clients," says Paul Nehlen, president and CEO.

"AquaRevival is constantly looking for ways to improve water quality and bather safety, so increasing our NSF 50 Crypto log reduction supports these objectives."

For more than eight years, AquaRevival has been certified by NSF International to new criteria in NSF/ANSI/CAN Standard 50, Equipment for Swimming Pools, Spas, Hot Tubs, and Other Recreational Water Facilities.

In addition to its industry-first NSF 50 Crypto certification, AquaRevival was the first to introduce compact ASME-designed pressure vessels, offer 15-year warranties as standard, achieve an NSF 3.0 gpm/sf high-flow rating, and offer patented Clean-In-Place technology, among many other achievements.

Rodney Allison, founder and owner, Allison Aquatics Group, says: "With the announcement of the new NSF crypto certification for pool filters, Paul Nehlen of AquaRevival - affectionately known to us at Allison Aquatics Group as the 'Mad Scientist' - has once again surpassed expectations with his innovative regenerative filter designs.

"This certification will allow us to deliver savings in the initial construction and operating costs, efficiency, and most importantly, the safety for the end user. AquaRevival is second to none in innovation, design, and manufacturing of regenerative pool filters."

AquaRevival sets a new standard in water filtration in the aquatics industry. Its internationally patented system uses state-of-the-art regenerative media technology to provide filtered water that is NSF 50, 61, and 372 certified for aquatics and F&B applications.

“Specifying AquaRevival’s efficient filtration systems offers our clients substantial cost savings,” said Josh Martin, president and creative director of Martin Aquatic.

“Now with the added NSF Crypto certification, we can offer them peace of mind as well.”

Combining time-saving automation with a sustainable water-saving process, AquaRevival systems offer aquatics facilities and operations managers in a range of sectors a straightforward way to minimise costs while providing the cleanest, purest water.
