12 months peace of mind
AerisGuard products have been specifically designed for air conditioning applications using solutions originally developed for medical infection control applications. Once treated, contaminants are prevented from building up inside of your air conditioning unit protecting you and your family for 12 months.

Competitors Cleaning Process
There are two primary components of your home air conditioner where microbial contamination occurs, each individual component appeals to different microorganisms:
|
The indoor coil
|
|
|
|
|
The filters
|
How does it work?
AerisGuard for home air conditioners is applied by a professional applicator using the Total Air Care Pack. The pack consists of a five step treatment using four specially-formulated products. Each of the four individual products has been specifically designed for specific components of your air conditioner.
They have a strong residual action, which protects the indoor coils from being re-contaminated for one year. There is also an ongoing treatment for the air filters, to prevent harmful organisms from congregating in the collected dust.
An AerisGuard Total Air Care treatment consists of the following steps:
- Contact Pre-Cleaning
The removal of bulk contaminants.
- Cleaning of indoor coil with AerisGuard Coil Cleaner
Removing existing mould and bacteria without damaging coil structure.
- Application of AerisGuard Coil Treatment
Protects the indoor coils against re-colonisation of mould and bacteria for 12 months.
- Cleaning of filters and Application of AerisGuard Filter Treatment
Provides protection against re-colonisation of mould and bacteria on filters.
- Insert the AerisGuard Condensate Pan Tablet
Protects drain line from blocking.
1. Contact Pre-Cleaning
The technician will vacuum the visible build-up of contaminants from the coil face. These contaminants include dust, microorganisms and hydrocarbon fumes which have not been trapped by the filter. These particles are trapped on the coil surface. These microorganisms will then form what is called "biofilm", a thin layer of living cells coating the surface. Since the coils are warm and damp, there are plenty of nutrients on hand for these microorganisms to thrive. As these bacterial microorganisms regenerate, they shed bacterial endotoxins and other potentially toxic organic fragments. These are the fragments that are blown into the indoor atmosphere.
2. Cleaning of indoor coil with AerisGuard Coil Cleaner
The first layer of contaminants is visible because of the build-up of dust. However, there are still millions of living microorganisms living on the coil. The AerisGuard Coil Cleaner is applied to cooling and heating coils to remove any existing bacteria or fungi, ensuring the coils are clean. The enzymes target the biofilm and dissolve the bonds allowing the biofilm to be gently washed away. The cleaning treatment is pH neutral and has no detrimental effect on the heat exchange surface.
3. Application of AerisGuard Coil Treatment
The next step is to treat the coil with a microscopically thin coating of an active biostat (a chemical used to prevent growth of biological organisms). This biostat is formulated to release a small amount of the active over a period of 12 months, protecting the coil from re-contamination.
4. Cleaning of filters and Application of AerisGuard Filter Treatment
The air conditioning filter is designed to trap dust particles. These particles provide nutrients for fungi, which quickly colonise untreated filters. AerisGuard Filter Treatment is based on a patented technology that releases a combination of active compounds onto the dust particles trapped within the filter, that inhibit the microbial colonization of the filters. Aside from the potential health consequences, the build-up of a fungal "root system" ultimately leads to the filter becoming blocked. Since the filter treatment retards this fungal growth, the filter life is extended and the filter's dust retention is improved, which in turn reduces energy consumption.
5. Insert the AerisGuardTM
Condensate Pan Tablet
Drain pans are a primary area of microbial contamination within the air conditioner. The AerisGuard Condensate Pan Tablet is an advanced multifunctional composition of enzymes and biostats. The tablets, which dissolve slowly over months, eliminate contamination formation in drain pans and drain lines, reducing the risk of blockage and condensate overflow.
Potential coil contaminants
Bacillus is a gram-positive bacterium, of which 48 species are known. They are rod-shaped spores which require oxygen. Species within the bacillus family are the causes of anthrax and food poisoning.
Pseudomonas is a gram-negative bacteria, of which more than 140 species are known. They spread via moist surfaces, including air conditioners.
In terms of human diseases, Pseudomonas aeruginosa is the most common, and is an extremely opportunistic bacteria, attacking and infecting skin tissue in humans that have been compromised (cut, burnt etc.)
The good news is that it rarely infects tissue that is unharmed and humans who are healthy. The bad news is that there is hardly any human tissue that it cannot infect if the tissue defenses are even slightly compromised.
These bacteria are clinically important because they are resistant to most antibiotics and they are capable of surviving in conditions that few other organisms can tolerate. They also colonize the lungs of cystic fibrosis patients, increasing the mortality rate of individuals with the disease. Infection can occur at many sites and can lead to urinary tract infections, sepsis, pneumonia and many other problems.
Flavobacterium are common in all water systems, and are opportunistic pathogens (organisms that produce disease) in humans. In humans Flavobacterium spp. has been associated with neonatal meningitis and septicemia, catheter-associated bacteremia, and pneumonia.
Candida is a genus of yeast-like fungi, which commonly infect the skin. Candida depends on a living host for survival, and the species are part of the normal flora of the mouth, intestines and vagina. Several species may cause infection in humans, especially immune compromised persons.
Candida albicans is one of the most commonly encountered human pathogens, causing a wide variety of infections ranging from minor infections in generally healthy persons to life-threatening infections in individuals with a lowered immune system.
Rhodotorula are a reddish yeast fungi found in moist environments such as cooling coils and drain pans. In some countries it is the most common yeast genus identified in indoor air. Some strains are particularly fond of humans with a suppressed immune system, causing symptoms similar to allergies. For individuals with catheters, Rhodotorula can cause a range of serious symptoms.
Potential filter contaminants
Aspergillus is a group of moulds which cause allergic diseases in asthmatics and patients suffering from cystic fibrosis. They include over 185 species, around 20 of which have so far been reported as causative agents of opportunistic infections in man. These range from chronic pulmonary infections (when aspergillus invades the lung), to sinusitis.
Penicillium is a filamentous fungus which can be found in the air. Although variants of the species are used to produce penicillin, other varieties can cause infection in people with suppressed immune systems. Penicillium has been found present in patients with such ailments as pneumonia, endocarditis, peritonitis, and urinary tract infections.
Alternaria is a type of fungi of around 50 species, some of which are found in an indoor air environment. They are extremely opportunistic pathogens (disease-producing microorganisms and toxins) and are often the cause of sinusitis. They grow rapidly, and the colony size can reach up to 9cm within 7days. The surface is greyish white at the beginning, which later darkens and becomes greenish black or olive brown with a light border.
Cladosporium is a mould of over 30 species, widely distributed by air. Some species are causative agents of infections such as skin lesions, keratitis, sinusitis and pulmonary infections.
