The ReSPR Hydra2 substantially reduces odors in commercial and industrial installations, and microbial populations in air and on surfaces, utilizing the NCC technology.

Perfect for odor control, contamination prevention, etc…

Hydra2 is probably the most powerful and the most versatile odor control for commercial and industrial installations.

*Scientific tests have demonstrated the use of ReSPR surface and air purifiers substantially reduce microbial populations on surfaces. These products are not intended to diagnose, treat, or cure any disease.


The ReSPR Hydra2 has been designed for heavy duty odor removal., specifically in water treatment plants, where Hydrogen Sulfide (H2S) is often a problem.

One Hydra unit is capable of handling H2S concentrations of up to 900 ppm, reducing them by up to 96%. Multiple Hydra units can be mounted in parallel to handle higher concentrations or reach better results.

Hydra can also be mounted parallel to a kitchen exhaust system, injecting our powerful oxydants inside the ducts, reducing the cooking odors by up to 98%.

IMPORTANT: Hydra is not designed for use in occupied spaces.

Why ReSPR?

ReSPR manufactures and sells products that address air purification in commercial markets. Our products include both stand alone and HVAC units which require installation into existing heating and air conditioning systems. In addition, ReSPR offers specialised air purifiers to handle odour and bacteria treatment, restaurants, bars, hotels, offices, food storage facilities, waste areas, industrial facilities and indoor areas damaged by smoke and fire.

Our technology is the only one that combines up to five nature-based technologies working together to treat indoor air like nature cleans outdoor air – using two types of ionisation to reduce particles, UV and a catalyst to create oxygen and hydrogen based friendly oxidisers to reduce microbial contaminants, and low level ozone to reduce odours.
