Ultra Pure ClO2
Technology Advantages
Best technology to disinfect to kill mold
and other pathogens in living spaces, base-
ments, crawl spaces, and attics
Best killing capability
Does not corrode home electrical,
HVAC and plumbing systems
Safer for workers
There are a number of disinfectant technologies on the market today.
Sellers of the various technologies claim to kill bacteria, mold and oth-
er pathogens. A close review of product information, SDS, and indus-
try association information reveal:
1. Some claims are exaggerated
2. Safety measures that must be implemented to ensure work-
er safety.
3. That we should be aware of the corrosive nature of the
products in regards to electrical, HVAC, and plumbing sys-
tems in homes.
Ultra Pure ClO2 Advantages
The following technologies are supplied by various manufactures and
sellers to disinfect homes:
1. Ultra Pure Chlorine Dioxide
2. Sodium Hypochlorite (Bleach)
3. Hydrogen Peroxide
4. Quaternary Ammonium
5. Sodium Percarbonate
The above methods use chemicals that act as oxidizers. The oxidizing
process breaks down the cellular structures of the bacteria, mold, and
other pathogens.

The disinfection power varies between the technologies. Higher oxi-
dation capacity signifies greater ability to eliminate pathogens using
less disinfection concentrations. The following chart compares oxida-
tion capacities:
The following chart compares the killing capability (Efficacy)
of the various technologies:
B= Bactericidal, V = Virucidal, F= Fungicidal, S=Sporicidal
Technology Efficacy
Ultra Pure Chlorine Dioxide High B, V, F, S
Sodium Hypochlorite (bleach) Moderate B, V, F, S if prolonged
Hydrogen Peroxide Low B, V, F, S if prolonged
Quaternary Ammonium F, Limited B, V, No S
Sodium Percarbonate Low B, V, F, S
Ultra Pure ClO2 Advantages
A by-product of oxidation is the possibility of corrosion of metals.
ClO2 is the least corrosive oxidizing chemical.
Technology Corrosion Possibilities
Ultra Pure Chlorine Dioxide Negligible at use concentration
Sodium Hypochlorite (bleach) Corrosive to iron and alumi-num. Compounded with caus-tic may cause bluing on stain-less steel
Hydrogen Peroxide High on aluminum, iron and zinc
Quaternary Ammonium Corrosive to iron, copper and brass
Sodium Percarbonate Low

Technologies reviewed are designed to be used by professional service
providers. Proper PPE is recommended. ClO2 is a Category 2 irritant.
Most others are Category 1 irritants which can cause more severe skin
and eye damage
Technology Toxicity
Ultra Pure Chlorine Dioxide Category 2 Oxidizing Solids Negligible at use concentration - prolonged exposure could cause slight skin or respiratory irritation
Sodium Hypochlorite (bleach) Category 1 H314 Extremely irritating to skin Category 1 H318 Eye damage Category 2 H401 Toxic to aquatic life
Hydrogen Peroxide Category 1 H314 Extremely irritating to skin Category 1 H318 Eye damage Category 2 H401 Toxic to aquatic life
Quaternary Ammonium Category 1 Severe Skin Irritation, contact dermatitis Triggering of asthma symptoms Eye and mucous membrane injuries Category 1 Acute Hazard Aquatic"
Sodium Percarbonate Category 2 H272 May intensify fire; oxidizer. Category 2 H315 Causes skin irritation. Category 4 H302 Harmful if swallowed Category 2 H319 Causes serious eye irritation.
