MOLD GLOSSARY
MOLD CAN BE FOUND IN MANY AREAS OF YOUR HOME

If you have a moist basement then you know you have mold. Many people believe once the mold is dried and removed the danger is over. Dried mold particles become airborne and can be breathed in even from your basement through ventilation systems and walls. Breathing in these very toxic particles can cause irreversible lung damage and even infect the body systemically and kill. There are litleraly thousands of different strains of mold.

Absidia sp. - A zygomycete fungus which is considered common to the indoor environment. Reported to be allergenic. May cause mucorosis in immune compromised individuals. The sites of infection are the lung, nasal sinus, brain, eye, and skin. Infection may have multiple sites. Absidia cormbifera has been an invasive infection agent in AIDS and neutropenic patients, as well as, agents of bovine mycotic abortions, and feline subcutaneous abscesses. Acremonium species may be confused with Fusarium species that primarily produce microconidia in culture. Fusarium genera are generally much more rapid growers and produce more aerial mycelium.
 

Acremonium sp. (Cephalosporium sp.) - Reported to be allergenic. Can produce a trichothecene toxin which is toxic if ingested. It was the primary fungus identified in at least two houses where the occupant complaints were nausea, vomiting, and diarrhea. Asexual state of Emericellopsis sp., Chaetomium sp., and Nectripsis sp. It can produce mycetomas, infections of the nails, onychomycosis, corneal ulcers, eumycotic mycetoma, endophthalmitis, meningitis, and endocarditis.
 

Acrodontium salmoneum - Reported to be a fairly common airborne fungus and is considered to be allergenic. Can produce a trichothecene toxin which is toxic if ingested. It was the primary fungus identified in at least two houses where the occupant complaints were nausea, vomiting, and diarrhea. It can produce mycetomas, infections of the nails, onychomycosis, corneal ulcers, eumycotic mycetoma, endophthalmitis, meningitis, and endocarditis. It is the asexual state of Emericellopsis sp., Chaetomium sp., and Nectripsis sp.

Stachybotrys sp. - Aw (water activity) - 0.94, optimum Aw (water activity) - >0.98. Several strains of this fungus (S. atra, S. chartarum and S. alternans are synonymous) may produce a trichothecene mycotoxin- Satratoxin H - which is poisonous by inhalation. The toxins are present on the fungal spores. This is a slow growing fungus on media. It does not compete well with other rapidly growing fungi. The dark colored fungi grows on building material with a high cellulose content and a low nitrogen content. Areas with relative humidity above 55% and are subject to temperature fluctuations are ideal for toxin production. Individuals with chronic exposure to the toxin produced by this fungus reported cold and flu symptoms, sore throats, diarrhea, headaches, fatigue, dermatitis, intermittent local hair loss, and generalized malaise. The toxins produced by this fungus will suppress the immune system affecting the lymphoid tissue and the bone marrow. Animals injected with the toxin from this fungus exhibited the following symptoms: necrosis and hemorrhage within the brain, thymus, spleen, intestine, lung, heart, lymph node, liver, and kidney. The mycotoxin is also reported to be a liver and kidney carcinogen. Affects by absorption of the toxin in the human lung are known as pneumomycosis. This organism is rarely found in outdoor samples. It is usually difficult to find in indoor air samples unless it is physically disturbed. The spores are in a gelatinous mass. Appropriate media for the growth of this organism will have a high cellulose content and a low nitrogen content. The spores will die readily after release. The dead spores are still allergenic and toxigenic. Percutaneous absorption has caused mild symptoms.

Molds reproduce by making spores that usually cannot be seen without magnification. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. Molds gradually destroy the things they grow on.
Molds gradually destroy the things they grow on. Prevent damage to building materials and furnishings, save money, and avoid potential health risks by controlling moisture and eliminating mold growth.

Many types of molds exist. All molds have the potential to cause health effects. Molds can produce allergens that can trigger allergic reactions or even asthma attacks in people allergic to mold. Others are known to produce potent toxins and/or irritants. Potential health concerns are an important reason to prevent mold growth and to remediate/clean up any existing indoor mold growth.

Using an Air-Zone Ozone Generator you can help eliminate and control mold growth in your home.

Only by the removal of the visible molds, disinfection of surfaces,  the gaseous cleansing ozone provides can illnesses from molds contamination be avoided.

Ozone generators reduce or eliminate the ability for the exposed mold, mildew and fungus to grow.
Mold and mildew grow in dark and humid places where there is a lack of oxygen.

Ozone acts 3000 times faster than chlorine as a bactericide, and it is the strongest oxidant commercially available for air & water treatment.

Ozone is a scientifically proven Mold Killer.   Click Here for proof.

The XT-6000 is the best standard model for strong odor, and mold remediation.  It has the highest ozone output for killing bacteria and mold. It can develop a higher parts per million ozone level in a given space than its smaller brothers. That higher level not only gets the job done faster, and better because of its higher output. To kill mold and remove strong odors there needs to be as high an ozone concentration as possible in the room.  Since ozone breaks down within 15 to 30 minutes it is important to keep producing large amounts of it to keep the ozone concentration at a sufficient kill level. Using a smaller machine twice as long is not the same as using a higher powered machine since the ozone breaks down so quickly.  With a smaller machine the ozone level never has a chance to "catch up" to the required parts per million concentration needed to kill the mold or bacteria. It is always recommended to use as large a machine as possible for mold and bacterial problems. That's why the XT-6000 is the choice of homeowners and professionals that deal with severe problems.

For professional applications, or larger area jobs the XT-24000 is an ozone generator with no equal. It features a phenomenal ozone output of 24,000 milligrams per hour without an oxygen tank. It is capable of remediating an entire floor of a house at once, and sometimes an entire home. It can be used in very large rooms that would normally require multiple ozone generators used at once. It has the power to obliterate mold in air handling systems when fired into the return air duct. CLICK HERE to learn more about the amazing XT-24000!

Mold Test Kits Mold test kits are the method professionals use to determine if there is a mold problem.  Our simple, do-it-yourself test identifies dangerous molds & mildew in 48 hours.  Optional lab analysis is available to indicate the exact count and type of mold & mildew present. The kits may be used one time. For multiple area testing additional kits will be required. Mold testing is the only way to know what kind of mold you have. Testing is also the only method to know if you have killed the mold after remediation. Click Here to learn more about our professional Mold Test Kits.
