What are HEPA Air Filters?
The Environmental Protection Agency has determined that almost 90% of the people spend their time indoors. This means that indoor air quality is much more important than outdoor air quality for most people. HEPA (High Efficiency Particulate Air) filters are recommended by allergists and medical professionals for the removal of all dust particles in the size range of droplet nuclei from the air. The HEPA filter, a mechanical filter, was developed by the Atomic Energy Commission of U.S.A. during World War II to prevent radioactive particles from escaping from plants and laboratories. Those initial HEPA air filters were very bulky compared to those that are produced today. HEPA filters are able to trap 99.97% of particles having the size of 0.3 micron, including harmful fibers, dust, smoke, pet dander, and more. With the capacity to collect dirt particles, which are 1/300th the width of the human air, these filters have high resistance power and cannot be placed directly in heating or cooling systems. These filters are used as the primary filtration systems for electronic clean room assembly, isolation wards, surgical theaters, bioengineering units, pharmaceutical processing units, and other places where the maximum removal of sub-micron particulate is required. They are also used in portable units to supplement a building's ventilation system by providing disinfected air. Doctors are advising the usage of HEPA filters in heating/cooling systems for the prevention and treatment of Tuberculosis. HEPA air cleaners, vacuum cleaners and air filters are essential by law to be used in all equipment for asbestos, lead, toxic chemicals, and mold abatement. The major benefit of HEPA filters is that they can remove Volatile Organic Compounds (VOCs) which are the gases that are released from household chemicals and synthetic materials. If filtration systems do not contain HEPA filters, all the toxic particles trapped in the room are left unfiltered. The price of portable HEPA filter unit ranges from approximately $100 to $3500, depending on the size of the unit.

The Benefits of Quartz Cuckoo Clocks Unlike windup cuckoo clocks, which require rewinding every one, two or eight days before, quartz cuckoo clocks use a more modern timing mechanism, drawing power from batteries and running continuously until the batteries run dry. Battery cuckoo clocks run for approximately one year on a new set of batteries give or take a little, depending on the type of battery used and the amount of animated movement built into the clock. Obviously, moving one small bird in and out of it's little house once an hour is going to take a lot less battery power than moving a small group of animated characters in a moving scene out of their housing, around to the front of the clock, sounding the cuckoo noise, playing the accompanying music, and moving them all back inside again as often as every half hour, as is the case with some ornate clocks.
