Anti-microbial Treatments

Anti-microbial treatments for your HVAC system

DuctPro offers three anti-microbial treatments for your HVAC system, EnviroCON, OXINE and Sporicidin. EnviroCON and OXINE are manufactured by Bio-Cide International Inc. and Sporocidin is manufactured by Contec, Inc. All are EPA registered products. Many states have licensing requirements that must be met by air duct cleaning companies in order to legally apply anti-microbial treatments. DuctPro companies are all in compliance with these requirements, but there are many other providers who are not. Before you engage a company to apply an anti-microbial treatment to your HVAC system, it might be a good idea to make sure they are properly licensed.

EnviroCON eNVIRONcON

EnviroCON is a mild bacteriostat and fungistat that we use when the primary objective of the treatment is to remove odors associated with mold, mildew or bacteria. EnviroCON is unscented and is NOT a perfume, cover-up or masking agent. It works by oxidizing the causes of these odors, not by adding its own scent to the air coming from your ducts. EnviroCON is an effective bacteriostat and fungistat that inhibits the reproduction of odor-causing microorganisms such as mold and mildew. Its active ingredient is Chlorine Dioxide (0.1%). This product is completely safe for building occupants including children and pets. No evacuation is necessary during or after application. When the product dries completely (in an hour or two), there is almost no residue and what little is present is inert and has no further chemical action.

However, please note that, even with a product as mild as EnviroCON, if you or other building occupants have a history of sensitivity to chemical treatments, it is wisest NOT to have us apply this treatment in your air ducts. The price for this treatment is $75 when applied as part of a full system cleaning.

OXINE oXINE Heating Ventilation Air Conditioning (HVAC)

OXINE is a true sanitizer and much stronger than EnviroCON. We apply OXINE in the air ducts of our customers when the primary objective is a 100% kill of all mold, mildew and viruses/bacteria that may still persist at a microscopic level even after a thorough duct cleaning has been carried out. OXINE has been shown to be effective even against microbes such as Stachybotrys chartarum, Mycobacterium bovis (Tuberculosis), Aspergillus fumigatus spores, Legionella pneumophila, Mucor sp., Penicillium roquefortii, Pseudomonas aeruginosa, and Trichophyton mentagrophytes.

OXINE is often the sanitizer product of choice for those among our customers who have family members with asthma or severe allergies. In many cases, these customers are intent on removing from their ductwork any and all possible triggers of allergic reactions.

Our technicians use respirators while they apply OXINE. All building occupants are required to evacuate during the treatment and for at least one hour afterward. Like EnviroCON, however, OXINE becomes entirely inert and odorless after it is dry. Its active ingredient, Chlorine Dioxide (2%), provides no residual action at all after drying, which means no off-gassing of VOCs (volatile organic compounds). VOCs are infamous for causing greater distress to highly allergic people than the microbes they are supposed to target.

Even though this product is strong and effective, it's toxicity is so low that the EPA assigned it a Category III toxicity rating (category IV is the lowest). However, as with EnviroCON, if you or other building occupants have a history of sensitivity to chemical treatments, it is wisest NOT to have us apply this treatment in your air ducts. The price for this treatment is $150 when applied as part of a full system cleaning.

Sporicidin Sporicidin logo

Sporicidin Disinfectant Solution is also a true sanitizer and provides a 100% kill of disease and odor-causing organisms on hard, non-porous surfaces. Unlike most other anti-microbials, Sporicidin is EPA registered to provide up to six months of continuous residual bacteriostatic activity after it is applied to surfaces.

Our technicians use respirators while they apply Sporicidin. All building occupants are required to evacuate during the treatment and for at least one hour afterward. The active ingredients in Sporicidin, Phenol (1.56% by weight) and Sodium Phenate (.06% by weight) are powerful anti-microbials. The Material Safety Data Sheet (MSDS) shows no inhalation risk but if you or other building occupants have a history of sensitivity to chemical treatments, it is wisest NOT to have us apply this treatment in your air ducts. Not for use on unlined flex ducts or on porous duct surfaces such as fiberglass duct board. The price for this treatment is $150 when applied as part of a full system cleaning.
