The Tri-Star vacuum cleaner continues to be made here in the USA from 1937. First in California and later in Texas.
The vacuum cleaner itself is made from die-cast metal, and is a canister style vacuum cleaner. The motors have varied in poer over the years, but now the machine has a all metal motor that wil still pick up a bowling ball. I know, I saw it.
Conventional vacuums will eventually lose suction and power since the airflow, that is certainly fundamental for meaningful vacuuming, is partly or completely blocked. In the usual vacuum cleaner, once filth and debris start filling the bag, the air must be pulled through the dirt and pet hair, limiting the airflow and causing the machine to lose strength and suction. Owing to our original cyclonic action, the vigorous motor of the TriStar MG3 vacuum directs incoming air movement over the dirt, consistently blasting the back of the bag clean..enabling full open airflow. Also when the paper filter bag is full, the airflow and suction power are unaffected. There is no significant reduction in power because air passes over the dirt and debris in the bag and not through it. That process is known as Cyclonic Action and is the thing that makes the Tri-Star distinctive.
The power nozzle is a bit loud, and is just a little bit better quality than most vacuum cleaner cleaners. But the geared belt will never break, and so that is worth something.
But what about the indoor air pollution? What about odors with pets, smoke, rubbish, etc.
If you ask shoppers about air pollution, they nearly always discuss the air pollution in the open air. But this seriously is not the main air pollution problem you deal with. The US Environmental Protection Agency studies of human subjection to air contaminants show that indoor levels of several pollutants are generally 200%-500% higher than their out-of-doors levels.
Acute sensitivity could be the most familiar health problem with indoor air quality in buildings. They can be connected with pollen, dust mites, and pet dander. In fact pet dander makes up a considerable percentage of the airborne dust in a house with dogs or cats that shed. Asthma can also be agrivated by subjection to particular types of inside air pollution.
So the question is "How do we protect our families against exposure to enclosed air pollution?" Cleaning Systems like the TriStar MG3 vacuum cleaner that cleans and refreshes the inside air. When used together, the TriStar MG3 Series Cleaning System can remove as much as 99.97% of all allergy and bronchial asthma producing particles 0.3 microns and larger, such as from smoke, pollen, dander, and germs.
