It is proven to disinfect viruses, bacteria, fungi and mold spores quickly and effectively. Powerful UV-C Radiation Natural & Effective Sterilisation Ultraviolet (UV) radiation is optical radiation with wavelengths shorter than visible light; and is present in sunlight. It can be divided into 3 functional categories: UV-A, UV-B and UV-C, as shown below. Germicidal UV disinfection uses energy from the short wavelength UV radiation to kill bacteria, fungi, mold spores and to inactivate viruses. UV-C radiation is more effective for sanitizing applications than UV-B and UV-A. The sterilization curve pictured above shows the germicidal effectiveness of different UV wavelengths, the peak is very near to the 253.7 nm wavelength present in the UV-C light sources inside the REALCLEAN. UV-C radiation has been used in healthcare applications to disinfect bacteria and other pathogens for decades. More recently, UV-C has been shown to inactivate SARS-Coronavirus particles by damaging important particle structures so the virus cannot reproduce or multiply. Airborne particles are exposed to the disinfecting UV-C light as air is circulated through the REALCLEAN. Application Area REALCLEAN Air Sanitizer incorporates 3X high-power UVC lamps which neutralize micro-organisms, reducing the risk of contracting or spreading viruses and bacteria in a wide range of applications. ​ Home Keep a healthy family, and make our home a virus-free, safe and comfy place to stay ​ School Lower the impact of respiratory disease due to long hours in a closed area ​ Office Protect the staff from the spread of communicable diseases Hotel Disinfect guest rooms, reception areas and club house facilities to maintain a safe environment Retails & Mall Ensure a virus-free and safe environment for shopper Restaurant Minimize the risk of spread of communicable diseases ​ ​ ​ ​ How many REALCLEAN Air Sanitizers are required for your space?
