Indoor air in the home is a favorite with microbes, dirt, grime and a variety of pollutants. Since we cannot see them, it is easy for colonies to grow and for particles of various hues to accumulate undetected by the untrained eye. These contaminants have an insidious capacity to affect human health, and target children, the elderly and people recuperating from chronic illnesses.


Sylvia Crunk, an authority in indoor air purification and owner of Aire Serv Heating and Air Conditioning in Austin, Texas, explains that tight sealing of indoor areas, which became a practice since the 1980s, acts to concentrate contaminates of indoor air to many times the levels found in most outdoors. "Indoor air needs to be filtered to deal with this heightened risk to human health, and air ducts need to be sealed and cleaned regularly to prevent fresh influx of pollutants," she says.




Microbes are amongst the most dangerous of the legion contaminants of indoor air in the home. Dust mites and molds are the most common pathogens in this category. They thrive in the dark and dank micro-environment of Heating, Ventilation and Air Conditioning (HVAC) systems, and are light enough to ride on circulating air in order to gain access to human skin and respiratory systems. The US Environmental Protection Agency and the American Academy of Allergies, Asthma and Immunology (AAAAI) have found that these organisms act as common allergens or environmental triggers, and contribute significantly to widespread and growing incidence of respiratory diseases and allergic conditions.

It is common knowledge that dust and particles of dirt can ride on air inside homes. However, many home owners take this phenomenon for granted and remain blissfully unaware of their harmful effects. Modern homes use a wide range of chemicals. The latter may enter indoor home environments both through cosmetics and cleaning products which are purchased, and also by way of surfacing used for tops and furniture. Some of these chemicals may have relatively low vapor pressure, and emanate noxious fumes at ambient temperatures. Sealed air circulation systems would pick up these vapors, because of which appropriate filters must be kept in top working condition. It appears that there is no end to the threats we face from the composition of indoor air in our homes.

Fortunately, this need not be the case. It is simple, easy and economical to invest in a quality HVAC system with a Preventive Maintenance Agreement (PVA) from a certified and reputed service provider. The first step is to ask for a survey of your home and an inspection of any installed equipment which exists already. Such a service can cost as little as $200, and will provide you with a scientific and detailed basis which you can use to decide on changes that you may need. The lay out of your home and its immediate surroundings will determine the kind of air ducts, the type of filters and related technical details.

You can also opt for portable units which can treat areas of about a thousand square feet each, and which you can carry with you if you have occasion to change residence. Such basic steps will give your family and you the quality and quantities of fresh and healthy air that you need at home. The size of your investment could vary depending upon the size and location of your home, but you can rest assured that you will have unparalleled health and energy saving benefits, regardless of the tab.
