The ReSPR OVeRWATCH substantially reduces odors, visible smoke in the air, and microbial populations in air and on surfaces, utilizing the NCC technology.

Perfect for indoor pollution control, odor reduction, contamination prevention, etc…

NCC consists of a special UV light and photocatalyst target, creating an Advanced Oxidation Process containing several friendly oxidizers.

*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.


ReSPR OVeRWATCH can be installed in any dropped ceiling directly by replacing an existing tile, close to the source of pollution and/or the place of higher occupancy.


  • To use the 120/240 volt plug, be sure to locate the unit within 2m of a standard 120/240 volt grounded outlet. Long term use of an extension cord is not recommended due to safety considerations.
  • Installation must be by a licensed professional.

OVeRWATCH works without any filter and only needs a small intervention every 2 years (replacement of the NCC cell).

And installing OVeRWATCH is amazingly simple: just remove an exisiting tile, connect the unit to the main and place the OVeRWATCH in lieu and place of the removed tile, on top of the metal grid. Job done.

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.
