nVIRO Shield by Woodard

nVIRO Shield® Comparison to Commonly-Used Disinfectants

Woodard's nVIRO Shield® pathogen control system is a revolutionary way control the spread of pathogens and protect your health. Using an electrostatic mister, EPA-designated safe products are applied to all surfaces, ensuring 100% protection from pathogens. In a matter of seconds, nVIRO Shield® will kill all common pathogens, fungi, bacteria, viruses that are treated with the system. The application process reduces human error and eliminates cross contamination by utilizing the electrostatic mister technology to coat all surfaces, rather than requiring hand-wiping.

Factors of Comparison Between Disinfectants

  • Time between disinfectant being applied and organism to be killed
  • Residual effectiveness and the time required to repeat the process of disinfection
  • Selectivity of the chemical disinfectant on vegetative bacteria, spores, viruses, and fungi
  • Labor and time required to apply
  • Effects of chemical disinfectants on staff and others in the treated environment

Disadvantages of Commonly Used Disinfectants

You may be unaware, but most of the commonly used disinfectants actually offer many disadvantages that could be harming you and your property.

Chlorine: Chlorine has broad antimicrobial activity, but is less effective against spore-forming organisms. It can cause ocular irritation, burns to the gastrointestinal tract, and it is also corrosive to metal at high concentrations. Furthermore, it is typically mixer-dependent, has a very short shelf life, and is often misused. Chlorine also has no residual protection.

Bleach: While bleach can be an effective sanitizer, it is not an effective disinfectant. Bleach reduces, but doesn't necessarily eliminate, microbes from hard surfaces to levels considered safe by public health codes or regulations.

Alcohol: Alcohol provides the highest bactericidal effect when a 70%-80% aqueous solution is used; the bactericidal action of 100% ethanol decreases. It is ineffective on spores, evaporates quickly, and has no residual effectiveness. Alcohol's bactericidal effect decreases when used in low temperatures and its effects are generally short-lived. Alcohol also tends to be ineffective against many viruses.

Hydrogen Peroxide: Hydrogen Peroxide is often preferred because it causes far fewer allergic reactions than alternative disinfectants. This product is no longer recommended for antiseptic use, as recent studies have shown it to be toxic to growing cells as well as bacteria. Hydrogen peroxide also has a short shelf life with no residual protection.

Phenol: This disinfectant is corrosive to the skin, can be toxic to sensitive people, and has no residual effectiveness.

UV Light: All of the above disadvantages with commonly used disinfectants created the need to use ultraviolet light for disinfection; however, not only is UV Light carcinogenic, it is ineffective for shadowed areas and has no residual effectiveness. Therefore, UV light disinfection should not be used alone, but with the addition of chemical disinfection. UV is expensive, time-consuming, dangerous to occupants in the facilities being treated and can be difficult to use. Continuous intermittent exposure to the materials used in UV light treatment can become a serious health concern, and many pigments and dyes are affected by UV “photo tendering” causing yellowed and cracked materials and sealants.
