We advise those who live, work, etc. in smog-ridden, polluted cities to obtain a good air filter. We especially recommend filters which contain charcoal and a high efficiency particulate HEPA air filter. The charcoal removes most of the chemicals and the HEPA filter removes most of the particles. To be effective in an average room, the flow rate through the filter should be over 200 cubic feet of air per minute. The wise motorist will also install an air filter in his car for cleaning the air while driving in air-polluted cities. Auto stores and catalogs usually stock them.
When we are born, our lungs are new, fresh, clean, and rosy in color. If we could live in a dust-free atmosphere breathing deeply all our lives, then our lungs would remain as good as new for a long, healthy lifetime of use. Yet most people abuse their lungs! Some of this comes from external causes. The lungs are the only organs of the body which are directly affected by external conditions, specifically, the air we breathe into them! Mother Nature has provided protection against a normal amount of dust contamination: tiny hairs in the nose serve as filters and moist mucus in the passages leading to the lungs traps dust particles that we expel through the nose or mouth. The tonsils also serve as guards to trap germs. The lungs protect themselves remarkably well by expelling carbon dioxide through oxygenation and by discharging toxins into the blood for elimination via the kidneys. Your body is a miracle!
Unfortunately, most civilized people today live in very unnatural conditions. Almost everywhere there are abnormal amounts of pollutants in the air we breathe, especially in urban areas. Our lungs are often overloaded with more contaminants than they can handle. These are passed along into the bloodstream and to other parts of the body. The lungs of a modern city dweller become brownish from car smog, soot, etc. Even in most farming areas, the lungs must contend with pollens, excessive dust, poisonous pesticides, fertilizers and other toxic chemicals. A California study shows that 275 people die yearly in smog-riddled L.A. areas from smog. They estimate soon this figure could be triple that amount annually!
