Clean air is essential for good health, and this is especially true when it comes to indoor air.
As Humans, we spend close to 90% of our time inside; at home, at work and in recreational environments. Most people, however, are unaware of the effects that poor indoor air quality can have on their health.
Indoor Air Quality
According to the American College of Allergies, 50%
of all illness is aggravated or caused
by polluted indoor air.
There are two broad types of allergies:
hypersensitivity is the common kind of allergy
that causes hay fever, allergic asthma, food allergies
and some drug allergies. People with this condition have
a reaction within minutes of exposure to the allergen
low levels, symptoms include headaches, tiredness,
shortness of breath and impaired motor functions. These
symptoms sometimes feel like the flu.
Formaldehyde Extensive reviews of formaldehyde emissions sources have been published by the World Health Organization (WHO 1989), and Environment Canada and Health Canada (2001). Sources that influence indoor levels of formaldehyde can be divided into two broad categories: combustion and off-gassing. Combustion sources include cigarettes and other tobacco products, and open fireplaces. Off-gassing sources include wood products such as particle board and other building materials made with adhesives containing formaldehyde as well as some varnishes, paints, carpeting, drapes and curtains.
Results from studies carried out in Canada since the early 1990s consistently indicate that formaldehyde concentrations in Canadian homes range between 2.5 and 88 µg/m3with an average between 30 and 40 µg/m3(Health Canada 2005).
When formaldehyde is present in the air at levels exceeding 0.1 ppm, some individuals may experience health effects such as watery eyes; burning sensations of the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation. Some people are very sensitive to formaldehyde, while others have no reaction to the same level of exposure.
Epidemiological studies on the effects of chronic formaldehyde exposure consistently found respiratory and allergic effects at levels below 123µg/m3(Health Canada, 2005). In one study, formaldehyde levels in homes were associated with increased risk of atopy, after ruling out confounding from other indoor air pollutants (Garrett, et al., 1999). In another study, formaldehyde levels were significantly associated with hospitalization for asthma in children aged six months to three years,
Formaldehyde has been classified as a human carcinogen (cancer-causing substance) by the International Agency for Research on Cancer and as a probable human carcinogen by the U.S. Environmental Protection Agency
Asthma - Asthma is a rapidly growing public health problem. About 23 million people, including 6.8 million children, have asthma and 12 million people report having an asthma attack in the past year. Asthma accounts for nearly 17 million physician office and hospital visits, and nearly 2 million emergency department visits each year...
Mold Molds are part of the natural environment. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.
Molds can be found almost anywhere; they can grow on virtually any organic substance, as long as moisture and oxygen are present. There are molds that can grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. It is impossible to eliminate all mold and mold spores in the indoor environment. However, mold growth can be controlled indoors by controlling Air and moisture indoors.
Radon You can't see radon, you can't smell it or taste it, but it may be a problem in your home. Radon is estimated to cause many thousands of deaths each year. That's because when you breathe air containing radon, you can get lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste. Its presence in your home can pose a danger to your family's health. Radon is the leading cause of lung cancer among non-smokers. Radon is the second leading cause of lung cancer in America and claims about 20,000 lives annually.
What are Negative Ions?
Negative ions are odorless, tasteless, and invisible molecules that we inhale in abundance in certain environments. Think mountains, waterfalls, and beaches. Once they reach our bloodstream, negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress, and boost our daytime energy.
Benefits of Negative Ions
Negative ion generators (negative ionizers) have been
used for years to help rid closed indoor environments of
allergens such as dust particles, animal dander, pollen,
mold spores, cigarette smoke, cigar smoke, PM10 particulate
matter, etc. floating in the air.

Ozone oxidizes airborne pollutants, then reverts back to oxygen, transforming polluted air to pure and refreshened air.
Here is how the process works:
Oxygen molecules (O1 and O2) are converted to ozone (O3)
by either a high-voltage electrical charge (such as from
lightning), or by ultraviolet light (such as from the sun
As the 2nd most powerful oxidant in existance, the single oxygen atom proceeds to "oxidize" the particle it reacts with. This means it burns the particle, which changes its physical properties. As a result, the particle will no longer be toxic, and will no longer be able to reproduce if it is biological. In other words, the particle becomes completely harmless.
When the single oxygen (O1) molecule oxidizes the particle, it too is destroyed. This leaves behind the O2 it split away from, or pure and clean oxygen.
The Refrigeration Service Engineers Society has reported that electric-arc welders exposed to ozone levels of 0.2 to 0.3 ppm (parts per million) for a decade showed no adverse effects. The Surround Air Ionizers produce between 0.02 to 0.04 ppm of ozone. Also, according to the 1961 Encyclopedia of Chemical Technology, "During the 80-year history of the large scale usage of ozone, there has never been a human death attributed to it." To this day, there has still never been a single human death or incident of harm attributed to ozone.
This despite the fact that ozone was widely used in hospitals
during the first half of the 20th century, and is still
widely used in European hospitals. In addition, millions
of ozone air purification systems are in use worldwide,
both commercially and residentially.
However, at proper levels (0.02 ppm to 0.05 ppm), it will have a pleasant and clean smell to it, reminiscent of the smell outside after a lightening storm.
The positive health effects of negative ions have been known for almost a hundred years.
Negative ions increase the flow of oxygen
to the brain; resulting in higher alertness, decreased
drowsiness, and more mental energy," says Pierce J.

The use of negative ions to improve indoor air quality has attracted increasing attention in recent years. Although the physical action of air ionisers is accepted, there is still debate over their apparent biocidal action. A recent clinical trial in an intensive care unit suggested that air ionisers may have a role in reducing the transmission of infection in healthcare environments1 and several authors have reported that ions inhibit the growth of a range of microorganisms. A further understanding of this process was gained through bench scale experiments exposing sessile cultures to positive and negative ions2. The aim of the work presented here was to follow on from the bench scale experiments to investigate the efficacy of negative ions with aerosolised microorganisms.
