Those with a bag

and Those without a bag

Domestic Bag-Type Vacuums have Two Basic Problems.

    They:
  1. Scatter Dust
  2. Plug Up

Bag Type Vacuum Cleaners scatter dirt and dust from one place to another - then CLOG UP - reducing suction power!

That's why you smell dust long after vacuum cleaning.

Vacuum cleaners do NOT produce a vacuum! Actually, the outer cloth bag, as well as the inner paper bag on some cleaners - has to be porous in order for the incoming air to escape.

As the illustration shows, dirt-filled air, drawn in at the nozzle - hits the wall of the vacuum cleaner bag with the full for of the motor. This action quickly clogs up the porous openings in the bag. As you can see, incoming air must pass through all dirt contained in the bag. Not only that, but the action also forces finer dust particles through the bag, scattering it all over everything in the room.

This illustration shows how fine dust particles filter through the cross fibers of the vacuum cleaner bag while the larger particles are trapped in the fibers - cutting down suction power, and steadily lowering the efficiency of the appliance.

Here you see the vacuum cleaner bag almost completely clogged with dirt. Suction power is sharply reduced. It's as if you placed your hand over the air intake of the vacuum cleaner - no air can be drawn into the bag, neither can dirt.

Empty the bag after every cleaning! All cleaners are more efficient when the dirt bags are clean. As the bag collects dirt, the flow of air through it is decreased, and a pressure develops which reduces the efficiency of the cleaner. Consequently, it is very important to empty the bag after each cleaning.

In place of scattering dirt and dust, the Silver King literally filters it out of the air, by means of a pure white sanitary filter, so efficient that the tiniest particles - even cigarette smoke - cannot penetrate its walls!

The magnified cross section of the filter shows how the layers of chemically treated cellulose Indian fibers effectively block the passage of dust particles, irritating pollens, and other impurities. As a result, only filtered clean air passes through and back into the room.

The in-rushing air-and-dirt stream is deflected by the Inlet Guide, which directs it to the bottom of the container, away from the filter. There, the heavier than-air dirt and dust particles gravitate to the bottom.

Thus, the air does not have to push its way through an accumulation of dirt and dust, as it does in a typical vacuum cleaner bag. Instead, the air returns to the room filtered and clean again. No wonder the Silver King has been called one of the major advances in home sanitation.

Asthma and allergies are a $520 million a year business creating over one million hospital visits each year. Over 100 million people around the world suffer from one or the other.

The most common allergies are to:

  1. Pollen
  2. Dust
  3. Dairy Foods
  4. Eggs
  5. Alcohol
  6. Animal Dander

Few people actually die of allergies unless they have asthma. The National Institute of Heath estimates that about 5000 Americans die each year from asthma. Asthma is a complex problem and the most chronic disease of childhood. It causes more children to lose time from school than any other disease.

One of the major triggers of asthma and hay fever is the common house dust mite. They move about your house on airborne dust particles virtually undetected because they are only about 1/200th of an inch in size.

Dust mites are members of the "Arachnid" family - relatives of Spiders and Scorpions!

Their primary diet is dead skin cells.

The highest concentrations of dust mites is generally found where there is a high degree of skin contact such as mattresses, overstuffed sofas and chairs, or carpeted areas near beds or showers.

In drier climates matresses are the "Primary Foci" or " Center of Activity" where perspiration and evaporative water from the human body provide mites with a source of water.

ONE Dust Mite can produce 20 fecal particles per day.

Reproduction takes six weeks, with a mature female laying up to 80 eggs during each cycle.

In Laboratory tests, to attain maximum results, dust mites are reared on dog biscuits, yeast, and electric razor shavings.

The New England Journal of Medicine reported that researchers from the University of Virginia and two British Hospitals found that children under one year of age who's homes had high levels of dust mite allergens were 4.8 times more likely to develop asthma in early adolescence.

They are one very good reason to keep your home as dust-free as possible.

The average person breathes 35 pounds of air each day; six times our food and water consumption, and half of this consumption occurs within the confines of our homes.

In case you didn't know, a normal adult breathes in around 35 lbs. of air every day and it contains literally billions-upon-billions of dirt particles. Considering that we spend an average of 90 percent of our time indoors, it becomes obvious that to keep allergies and irritant's at bay, we should make sure that the air we breathe is as contaminant free as possible.

Studies have shown that the air that circulates in a normal home is as dirty as that of a large city. As a result, an average person can expect to breathe in around 50 billion contaminent particles per hour.

Air-borne dirt comes from a number of sources: cars, vegetation, industries, smoke, pets and people. Pollen and dust mites, two of the most common irritants, are so small that they are invisible to the naked eye. Even dust mite droppings can easily enter our lungs and irritate our eyes.

Dirt is in our schools, workplaces, homes and in our cars. If the buildings where we spend large parts of our day are ventilated, things can get even worse. Poorly maintained ventilation systems are a prime source of "bad air," air that contains mold and bacteria circulated together with all the other particulate matter we end up breathing.

The particles that float in the air around us are so small that individually, they range from being hard to spot to completely invisible. They are easily whipped up from floors and surfaces to drift around until they either gently settle again, or are inhaled into our lungs.

When you consider that the average human hair is between 50 to 100 microns across, a dirt particle of 0.06 microns seems unimportant. But in large quantities, even particles this small can cause all kinds of problems. In high concentrations they cause problems in the form of irritations, allergies, asthma and bronchitis.
