New Research Initiative to Test if Ionization Can Remove Harmful Particles From the Atmosphere Before People Breathe Them

NAPLES, FLORIDA / ACCESS Newswire / February 5, 2026 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ:RAIN) today announced a research initiative to explore whether its proven ionization technology can remove harmful airborne pollution from the atmosphere. The concept is to use ionization to charge tiny particles suspended in smog and pull them to the ground, rather than leaving them in the air where they can be inhaled into lungs. The research represents a new application of the same technology RET uses to enhance rainfall and snowpack.

This initiative represents a natural extension of RET's successful ionization technology, which has demonstrated measurable precipitation enhancement results. The research will investigate how the same ionization principles that enhance rainfall and snowpack can potentially be applied to remove harmful particulate matter from the atmosphere through a process known as "dry deposition."

"This research initiative exemplifies our strategic advantage of maintaining a comprehensive team of scientific advisors who guide us through all phases of operations," said Randy Seidl, CEO of Rain Enhancement Technologies. "Our advisor-driven approach to innovation enables us to identify and pursue promising applications of our core technology, ensuring that RET continues to expand its environmental impact while building on proven scientific foundations."

The research is being conducted in collaboration with leading experts Dr. Arquímedes Ruiz-Columbié, an atmospheric scientist, and Dr. Daniel Martin, both recognized specialists in ionization technology and weather modification. Dr. Ruiz-Columbié serves as Senior Lecturer at Texas Tech University and President of Active Influence and Scientific Management. Dr. Martin is President/CEO of Pluvium, LLC and a retired Research Engineer with USDA-ARS.

"The same ionization technology that successfully enhances precipitation can theoretically be applied to attract airborne particulate matter and bring it to the ground," said Dr. Daniel Martin, Technical Advisor to Rain Enhancement Technologies. "This represents a promising approach to addressing one of the world's most pressing environmental challenges."

Air pollution affects billions worldwide, with fine particulate matter (PM 2.5) posing severe health risks. PM 2.5 refers to particles 2.5 micrometers or smaller in diameter-about 30 times smaller than human hair and invisible to the naked eye. These combustion-derived particles from vehicles, power plants, and wildfires can remain suspended in the air for days and penetrate deep into the lungs and bloodstream, causing cardiovascular and respiratory diseases. Traditional air pollution mitigation approaches have limitations, and there is growing global interest in innovative solutions for urban air quality management.

"Rather than having harmful particles suspended in the air where they can be inhaled into lungs, this approach would bring them to ground level through controlled deposition," said Dr. Arquímedes Ruiz-Columbié, Meteorological Advisor to Rain Enhancement Technologies. "Our previous research has shown that ionization can affect aerosol distribution in the atmosphere."

RET's ground-based "dry deposition" approach using WETA ionization technology could complement existing "wet deposition" methods, with different environmental conditions potentially favoring different technological approaches. The research will include controlled experiments to measure effectiveness and validate the scientific approach.

"This initiative demonstrates RET's commitment to expanding environmental applications beyond water security," said Scott Morris, Chief Technical Officer of Rain Enhancement Technologies. "We're exploring how our proven ionization platform can address multiple environmental challenges while maintaining our focus on sustainable, chemical-free technology."

The research is in early stages and subject to successful testing and validation. No assurance can be given that this research will result in commercial applications.
