FAQ: AIR PURIFER
WHY DO I NEED A AIR PURIFIER?
Indoor air pollution is an extremely serious threat to your health. Indoor air is typically 2 to 5 times more polluted than the air outdoors, mainly because modern building insulation techniques trap and concentrate pollutants as well as conserving heat. Pollutants enter from the outside air, and are also generated from inside the home. Indoor air typically contains mold spores, bacteria, viruses, pollen, dust mites, radon and chemicals from cleaning products and household tasks such as washing.

This is a significant threat to health as people generally spend 90% of their time inside, and 65% of their time at home. Those who are at greatest risk from these indoor pollutants are also those who tend to spend most time inside, such as pregnant women, young children, the elderly and those with chronic illnesses. People generally do not realize the threat from polluted air in the home, as many pollutants have no smell and are not visible to the naked eye. Symptoms are generally vague, such as headaches, itchy nose and throat, nausea, dizziness and tiredness and therefore their true cause is not realized.

Other, more serious symptoms include asthma and other respiratory problems and even various concerns. If left untreated, asthma due to air pollutants can lead to other chronic and serious breathing disorders, and can sometimes be fatal. Children are particularly vulnerable to the effects of indoor air pollution. A recent scientific study found that 65% of childhood asthma cases could be prevented by controlling exposure to indoor air pollutants including: dust mites, dander and tobacco smoke. Air purifiers remove these pollutants from the air in your home or office, protecting you and your family from this serious threat to health.

Your home and your office can have clean air for healthy living right now. As for how many units you need, a lot depends on your location (next to a busy road etc). If you start with one and move it about the house, have it in the bedroom first (most time) then move it to the next used etc. If then you find the unit is on all the time on full then get a second unit etc.
CLEAN AIR & YOUR HEALTH
When we hear the words 'air pollution,' we think of smog, auto emissions, factory smoke, etc. Recent research suggests that we may have been looking in the wrong places. Environmental scientists claim that the real risks to our health are much closer to home. It is indoor air quality that has the greater impact.

Not surprisingly, many of these risks have accompanied the technical advances in our lives. Improved building techniques and concern for energy efficiency have created airtight housing. These buildings retain and re-circulate indoor air along with any contaminants.

At the same time, many common materials in the home contain chemicals that are now implicated in conditions ranging from allergies and chronic respiratory irritation to cancer. A wide range of less severe but potentially debilitating health problems including headaches, chronic fatigue, drowsiness, difficulty concentrating, and even snoring can often be attributed to poor indoor air quality.These potentially harmful substances carried in indoor air fall into two groups: particles and gases.
THE PARTICLES IN OUR AIR
The minute, invisible particles in the air are a primary threat to health. They evade the body's filtering mechanisms and penetrate deep into lung tissue, carrying toxic substances which are absorbed in the body. The harmful particles, which include dust mites, pet damper, mold spores, and pollen, provoke allergic reactions in many people.

Some allergic reactions are severe - asthma is the best known and one of the most serious. Other allergic conditions are subtle chronic conditions. Runny nose, watery eyes, recurring headaches, lethargy, even snoring can all be symptoms of allergy. Many people endure these conditions, not knowing that they are allergy-related and that prevention is readily available.
HOW SMALL IS A MICRON AND DOES IT MATTER?
One micron is 1/25,000 of an inch. To understand just how small this is, consider that human hairs measure between 30 and 120 microns. Dust mite allergen measures from 0.1 to 0.3 micron and staphylococcus bacteria measures 0.7 micron. The size of a given particle helps to determine the degree of potential threat to human health. Particles ranging from 0.3 to 0.9 micron present the greatest health concern.

These irritating mid-range particles include house and textile dust, pollen, pet dander, dust mites and their feces, many bacteria, auto exhaust, mold spores, and particles from laser printers and copiers. Particles in this size range (0.3 to 0.9 micron) are small enough to get past the tiny hairs that line our breathing passages and too large to be easily exhaled.

Because mid-range particles are more likely to become lodged in lung tissue, they are suspect in a wide range of health problems related to indoor air pollution, from headaches and dizziness to cardiovascular disease and cancer. In particular, pollen, pet dander, mold spores and dust mite particles are known to trigger asthma episodes and allergy attacks.

While smaller particles (0.1 to 0.3 micron) can be inhaled and exhaled more easily than mid-range particles, even these minute particles may irritate breathing passages and lungs. Smaller particle filtration is particularly beneficial to people living with allergies, asthma, other respiratory conditions, or cardiovascular disease.
ARE THERE DIFFERENT TYPES OF AIR FILTERS?
Mechanical filters (i.e. fan-driven HEPA filters)
These force air through a special mesh that traps particles including allergens like pollen, pet dander and dust mites. They also capture irritant particles like tobacco smoke. The fans in these types of devices produce ozone byproduct and are usually within the acceptable level. Make sure to ask for proof from the manufacturer that their product is within the acceptable level of ozone byproduct.

Electronic filters (i.e. ion-type cleaners)
These use electrical charges to attract and deposit allergens and irritants.
If the device contains collecting plates, the particles are captured within the system.

Hybrid filters
These contain the elements of both mechanical and electronic filters.

Gas phase filters
These remove odors and non-particulate pollution like cooking gas, gasses given off by paint or building materials, and perfume. They cannot remove allergenic particles.
WHAT KIND OF FILTER DOES AN AIR PURIFIER USE?
Most air purifiers use either HEPA filter or washable stainless steel collection cell as their filtration media.
Some air purifiers also use pre-filter to increase the overall filtration efficiency.
WHAT ARE THE DIFFERENCES IN AIR PURIFYING TECHNOLOGIES?
Ultraviolet light is one of the more effective methods to reduce and control airborne pathogens. For this reason ultraviolet purifiers are commonly used in hospitals. As contaminated air is passed through intense ultraviolet light, bacteria, viruses and some organic compounds are destroyed. In short, the ultraviolet light damages the DNA of microorganisms and renders them harmless and unable to reproduce. Ultraviolet light is used in much the same way for water purification systems. Because viruses are too small to be trapped by HEPA filters, ultraviolet light is one of the only ways to eliminate airborne viruses.

A basic characteristic of UV lamps is that the larger the lamp, the greater the output of ultraviolet germicidal irradiation (UVGI). But larger or longer UV lamps that create ozone can also produce too much ozone. To solve this problem, RGF developed a proprietary broad spectrum, high efficiency UV bulb (HE/UVTM) to work with their hydrated quad-metallic target and PPC-UV bulb coating. The target acts as a catalyst for a hydroxyl radical reaction of the broad spectrum 100-300 nm HE/UVTM energy with water vapor on the hydrated target.

The results are hydro peroxides, super oxide ions, passive negative ions hydroxides and ozonide ions. The cell creates a very aggressive advanced oxidation atmosphere that has the ability to reduce airborne bacteria, mold and viruses up to 99% also odors and VOC's by up to 97%. A proprietary protective poly shield (RGF PPS) shields the bulb from temperature fluctuations and breakage that could release mercury, which is a problem for all UV bulbs. 

Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet. The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy.

HEPA is an acronym of High Efficient Particulate Air.
Any true HEPA filter guarantees that the filter will capture airborne particles down to 0.3 microns in size, 99.97% of the time. (Particles smaller than 0.3 microns are still trapped by HEPA filters but effectiveness is reduced to less than 99.97%.)
HOW EFFICIENTLY DOES MAIER AIR PURIFIERS CLEAN AIR?
Maier air purifiers cleans indoor air by drawing in polluted indoor air into the unit and trapping particles, allergens and contaminates onto the filter. The air purifiers removes even the tiniest particles (0.1 micron) that accumulate in our homes.

The Maier Hybrid Air Purifier (6000 series) is designed for larger rooms of over 65 square metre / 698 square feet.
