Product Overview:
The BoiE Hydra PRO-4 is a 4-Optic PhotoCatalytic (PCO) hydroxyl generator inside a rugged 2-position case. The unit has a quiet but powerful blower fan and is safe for continuous operation in occupied buildings to improve indoor air quality or to restore air quality following events such as floods or fires. The Hydra PRO-4 uses germicidal UV light to generate hydroxyls that eliminate odors, break down bacterial spores and pathogens, continuously cleaning the air.

The Hydra PRO-4 is a true hydroxyl generator, which means that it does not generate harmful ozone and is safe to use in occupied areas without affecting daily routines. For tough jobs, the Pro-4 can be configured to run in Advanced Oxidation Process (AOP) mode with monitoring and appropriate PPE when workers are present.*

PCO technology attacks and kills bacteria and viruses in the air but is safe to operate in occupied areas. Air purifiers alone will not destroy viruses circulating in the air; HEPA filtration cannot trap something as small as a virus, but PCO technology has been proven to kill viruses on contact.¹

The Hydra PRO-4 passes air through a UV light-activated catalyst that safely generates hydroxyls that neutralize contaminants. The resulting byproducts are harmless carbon dioxide and water, leaving nothing but fresh, clean air. Safe operation makes the PRO-4 a great choice to run 24-7 at occupied job sites or in homes and businesses.

How It Works:
Hydroxyls are highly-reactive (radical) molecules formed naturally when UV light from the sun splits apart water molecules in the air. The resulting hydroxyl radicals (and super-oxide ions) instantly oxidize pollutants nearby. Hydroxyls are nature's primary method of cleaning contaminants from the atmosphere using only sunlight and water vapor. Artificially-generated hydroxyls perform the same cleansing function on indoor air and cause no harm to people, pets, plants or materials.

Odors from flooding, mold spores, cigarette smoke, fire damage, sewage spills, off gassing, body odor and decomposition are all safely broken down by a hydroxyl generator until all that remains is carbon dioxide and water

PCO hydroxyl generation, originally developed by NASA to purify air onboard a space station, is ozone-free and safe to use indoors for continuous operation. Photocatalytic Oxidation is FDA-approved for use in Class II medical devices such as air purifiers, N95 respirators and infusion pumps. The Hydra PRO-4 has a 4-optic 254-nm UV-C (germicidal) hydroxyl reactor that causes no harm to occupants, pets, plants or possessions. The design uses space-saving U-shaped optics to pack the most power possible within a compact unit.

AOP Configuration (PCO / O3 + UV)
When configured for AOP, the Hydra Pro XL adds low concentration ozone, which is broken down into hydroxyls by germicidal UV light, without requiring a catalyst. The resulting reactions can double the unit's efficacy, increase the overall coverage area or shorten the cleaning time. PCO mode continues to run simultaneously. However, ozone levels in the air must be monitored if workers are present. Below is a simplified equation of the AOP:

UV Light / Ozone:
O₃ + H₂O + UV —› O₂ + H₂O₂ followed by 2 O₃ + H₂O₂ —› 2 •OH + 3 O₂


The Hydra PRO-4 has a powerful 465 CFM centrifugal fan that draws air through a carbon pre-filter, then through a nano-catalyst reactor. The rugged case is designed for long life in harsh environments. The unit is simple to service by opening two push button latches. Includes a straight blade AC inlet that connects to standard extension cords, rather than a permanently attached power cord.

The Hydra PRO-4 can be left running continuously in occupied areas for as long as it takes to remove odors and break down contaminants. The unit has the latest PCO technology including shielded 254nm UVC lamps rated for 9,000-hours. BoiE's unique 360-surround permanent, nano-anatase TiO2 reactor grid produces the highest levels of hydroxyls possible without restricting airflow.

Hydroxyl generators work best when humid air enters the machine. When conditions are too dry, the Hydra PRO-4 can be used with BoiE's Ultrasonic Hydroxyl Accelerator to increase the moisture level of the air that is drawn into the machine.

Reasons to Buy:
The Hydra PRO-4 is great for cleaning occupied spaces in its default PCO mode. The optional advanced oxidation process mode can increase the coverage area and decrease the cleaning time, provided that the job site is either unoccupied or is monitored for worker safety. Like all hydroxyl generators, the Hydra PRO-4 won't damage plants or sensitive materials. The unit strikes a good balance between air changes per hour (ACH) and fan noise. It is great to run during and after a mold remediation project to kill mold spores and to help pass mold clearance testing.

Like all BoiE products, the Hydra PRO-4 was designed by professionals for professionals to exceed, outlast and outperform the competition!

* The U.S. Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL), averaged over an eight-hour work shift, for ozone is 0.10 ppm. If configured for AOP, the Hydra Pro-4 may exceed PEL and require appropriate personal protective equipment (PPE). Monitoring is required if workers are present.
