Major primary chemical pollutants produced by human activity include:
Sulfur Oxides (SOx)
Sulfur oxides, especially sulfur dioxide, a chemical compound
with the formula SO2. SO2 is produced by volcanoes and in various industrial
processes. Since coal and petroleum often contain sulfur compounds,
their combustion generates sulfur dioxide. Further oxidation of SO2,
usually in the presence of a catalyst such as NO2, forms H2SO4, and
thus acid rain. This is one of the causes for concern over the environmental
impact of the use of these fuels as power sources.
Nitrogen Oxides (NOx)
Nitrogen Oxides, especially nitrogen
dioxide, are emitted from high temperature combustion. Can be seen
as the brown haze dome above or plume downwind
of cities. Nitrogen dioxide is the chemical compound with the formula
NO2. It is one of the several nitrogen oxides. This reddish-brown toxic
gas has a characteristic sharp, biting odor. NO2 is one of the most
prominent air pollutants.
Carbon Monoxide
Carbon Monoxide
is a colourless, odourless, non-irritating but very poisonous gas.
It is a product by incomplete combustion of fuel such as natural gas,
coal or wood inside the house. Vehicular exhaust is a major source of
carbon monoxide outside the house.
Volatile Organic Compounds (VOC)
VOCs are an important outdoor air pollutant.
In this field they are often divided into the separate categories
of methane (CH4) and non-methane (NMVOCs). Methane is an extremely
efficient greenhouse gas which contributes to enhanced global warming.
Other hydrocarbon VOCs are also significant greenhouse gases via
their role in creating ozone and in prolonging the life of methane
in the atmosphere, although the effect varies depending on local
air quality. Within the NMVOCs, the aromatic compounds benzene, toluene
and xylene are suspected carcinogens and may lead to leukemia through
prolonged exposure. 1,3-butadiene is another dangerous compound which
is often associated with industrial uses.
Inside the house, VOCs are invisible gases which are emitted from paints,
adhesives, carpeting, wall coverings, new furniture, building materials,
solvents, cleaning solutions, copy machines and laser printers. Studies
using experimental chambers have shown that VOCs can cause irritation
of the respiratory system in humans and animals.
Controlled experiments with people who suffer from Sick Building Syndrome
confirm that VOC exposure can cause headache, fatigue and difficulty
concentrating. Dozens of VOCs have been identified in residential air.
Some of the VOCs found in indoor air, such as benzene derivatives, may
promote cancer in humans. Concern over the safety of cleaning solutions
and VOCs has created a demand for less toxic alternatives.
We offer two air purifier brands that are proven to be effective at
removing chemicals and VOCs:
Airpura Commercial HEPA and Carbon Air Cleaners
Airpura Commercial Air Cleaner SALE! Save
10% on ALL Airpura Models
Airpura
is a completely new air cleaner with all the design improvements lacking in
other similar technology systems. Airpura design principles include a simplified
unobstructed air flow for quieter more efficient performance and reduced noise.
The prefilter can be vacuumed through the mesh for easy monthly maintenance,
then replaced every 12 months. Two special microbial (bacteria and viruses)
suppressing filters help to protect the hefty 18 or 26 pound carbon bed. Felt
gaskets are used to seal the filter chamber, eliminating rubber seal off
gassing. The metal capped HEPA filter removes the possibility of any
plastic vapors from non-metal caps.
Airpura uses a powerful, variable speed integrated fan/motor, letting you
choose the rate you clean your air from super quiet to premium power filtering
with 560 CFM capacity. With Airpura's effective pressure sealed filter chamber,
all air is filtered; NO particles or gases escape. Other systems allow
leakage and can't achieve the claimed 99.97% HEPA efficiency. And, Airpura
offers the cleanest air, using superior quality true HEPA and activated carbon
(special carbon blends are available) with optional UV sterilization to deliver
truly clean air for home, office and industrial applications. Airpura is available
in eight
models and three colors: Cream, white and black. more

Air Oasis Breakthrough G3 UV Air Purification Technology!
BIG Air Oasis SALE!
Save $50 to $125 on Select Models
No
air purifier on the market can compete in effectiveness, energy efficiency,
adaptability and quiet operation, when compared to the Air Oasis G3 patent-pending
Nano Nickel HCT photocatalytic oxidation technology. Other oxidation brands
use only titanium dioxide (TiO2) as a catalyst, the cheapest, most available
catalyst metal on the market, whereas Air Oasis contains five rare catalyst
metals and nano size metals to increase the kinetic rate of reaction.
Unlike HEPA filters that only remove some particulate and carbon filters that
only remove chemicals, VOCs and odors, Air Oasis technology is proven
effective against MRSA, bacteria, molds, VOCs, chemicals, gases, odors, pollen,
dander and more. Extensive testing conducted by West Texas A&M University
at BSA Hospital confirm that Air Oasis not only purifies your air, but sanitizes
surfaces, too. Additionally,
Air Oasis Air Purifers are made in the USA, using brushed aluminum casings
and UV lamps that utilize a proprietary long life
coating, allowing them to outlast any UV lamp on the market. Read

To a lesser degree, in cases with moderate chemical contamination, the following
air purifiers is effective:
Surround Air Multi-Tech Ionizers
Surround Air Multi-Tech Ionizer SALE! Save
10% on ALL Models
Negative
ions clean the air by magnetically attracting to pollutants until these newly-formed
larger particles become too heavy to remain in the air you breathe and they
fall to the ground. Surround Air Ionizers continually produce negative ions,
without creating the "black-wall" effect of older ionization technologies,
so even if one of these fallen particles is kicked up into the air, it is quickly
removed again. The most important thing, though, is that they are taken out
of the air, preventing you from inhaling them into your lungs, which is how
they cause problems.
Since certain technologies are much better than others at
removing different types of air pollutants, all Surround Ionizers are multi-technology.
All models include ionization, a prefilter, a HEPA and Carbon Filter and UV
lamp, plus some models include a TiO2 filter or an optional ozone sanitizer.
And, the Intelli-Pro includes electronic sensors. With Surround, you get the
best of the most advanced air purification technologies on the market, all
rolled into one air purifier. The best part is that Surround Multi-tech ionizers
and replacement filters are affordable
for every budget. more info
