Category: All About Vacuums

ActiveHEPAHEPA is not a material. HEPA (High Efficiency Particulate Arresting) is a standard of filtration. Specifically the standard requires that (99.97%  of all particulate as large  as .3 microns is trapped within the filter. The designation of HEPA is awarded by certified testing laboratories. There is nothing however in the rules that defines how long the filter must retain that efficiency. Neither are they rules that define under what rate of air flow the filter must perform.

Vacuum Cleaner Terminology

Air Flow

The movement of air from one location to another, usually measured in CFM (cubic feet per minute). It is the force exerted by the moving air which actually picks up the dirt and moves it into the bag or dirt container. This is one of the most important aspects of determining the true measure of vacuum cleaner effectiveness. Yet, sadly, few manufacturers publish these test numbers.

Types of Vacuums

Upright Vacuum

If you were to give a 4 year old a carton of crayons and paper and ask him or her to draw a “vacuum cleaner” he or she would draw a picture that would resemble an upright vacuum. This is by far the most popular style in the U.S. These vacuums are pushed in front of the user and have a handle extending from the main body. Most have a spinning brush roll, and many have onboard tools for cleaning upholstery, stairs or hard to reach areas.

If you don’t want to pay for a bunch of marketing and a lot of “features” that don’t really help you clean your floors any better, you should buy it from a place that also fixes them. Nobody understands what makes a vacuum work like the people who actually have to repair and maintain them. That’s what we do here at the Vacuum Store in Los Gatos.

Interesting Facts About Vacuum Cleaners

  • Most of the cleaning is actually accomplished by the brush system.
  • The primary job of the air flow is to transport the dirt to the containment system.
  • The secondary job of the air flow is to cool the motor.
  • High powered motors that produce very high volumes of air movement can cause particles to blow by the dirt transport path to the back of the floor nozzle housing, and escape capture.
  • In modern vacuums, the dirt path is through the hose and not through the fan chamber.
  • Most modern vacuums employ have filters in front of the motor, on the exhaust air vents, and in the motor compartment itself. All these filters require either cleaning or replacement.
  • Dirty filters can inhibit the free flow of air in the system and cause the motors’ operations to be compromised.
  • Dirty filters will cause dust to collect in the motor and be ejected into the room.
  • HEPA filters clogged with dust will inhibit air flow and cause the motor to overheat and possibly burn out.
  • A clogged HEPA filter will also create extra pressure on the seals and gaskets of the system and cause dust to be aerosolized into the vacuumed room through leaks in the seals and gaskets.
  • Filters in high ampere systems require more maintenance than those in lower power systems.
