FTC Settlement Requires Oreck Corporation to Stop Making False and Unproven Claims That Its Ultraviolet Vacuum and Air Cleaner Can Prevent IllnessHow is the Alive air purifier different from other air purifiers? The Alive air purifier differs from other models of air purifiers in that it includes multiple air filtering and cleaning mechanisms, such as HEPA filtering, UV light cleansers and ion filters, that others do not. It also offers features such as a timer and washable filters. What are the reviews on the Blueair 203 HEPA silent air purifier? Most air purifiers include a single phase or dual phase cleaning process, in which the air that passes through the device is filtered by one or two mechanisms, respectively. In the Alive air purifier, air is passed through seven different phases of cleaning. First a pre-filter catches hair and large particles in the air, and then a HEPA filter removes pollen, smaller pet hair and dust. After that, an ionic filter extracts pollutants and improves breathability.

Next, a UV light working in conjunction with a Tio2 filter — similar to what's used in hospitals — kills germs and mold in the air. Finally, air passes through an electrostatic filter to capture soot and smoke and then a carbon filter to trap gases and unpleasant odors. Other features that set the Alive air purifier apart form other air purifiers are washable and reusable filters, a timer that lets users automatically turn the filter on and off, and a dust sensor. , as of 2015.

The "True" HEPA filter was developed during World War II by the Atomic Energy Commission and it was designed to remove and capture radioactive dust particles from the air which might escape and present a health hazard to the researchers. The "True" HEPA filter was specifically designed to protect the Human Respiratory System. Even the CDC guidelines for the transmission of tuberculosis (TB) recommend that only HEPA filters with an efficiency of 99.97% tested at 0.3 microns particle size or smaller be used. The "True" HEPA filter is recognized byOSHA / EPA

as the ULTIMATE in cleansing the air and is a proven method. The "True" HEPAfiltration technology is currently the only type of air purification tool recommended by the U.S. Government's Department of Homeland Security and FEMA.

For a filter to be called a "True" HEPA , it must retain and filter out all particles from the air that passes through it down to 0.3 microns in size at an efficiency rating of 99.97%. A "True" HEPA Filters's efficiency DOES NOT decrease during it's life, it actually increases and its also known as an ABSOLUTE type filter media for particle capturing. For a filter to be labeled "True" HEPA , it must be certified 99.97%efficient in capturing 0.3 micron (not 0.1 or 0.01 etc..) respirable-size-particles (RSP) according to the U.S. Military Standard MIL-STD-282, commonly known as the DOP test. 0.3 micron is used and no other is because 0.3 micron is the size at which all mechanical filters are LEAST efficient in capturing. Other methods of testing do not give a true picture of efficiencies relative to respirable-size-particle (RSP) capture. "True" HEPA filtration is recognized as one of the most efficient air filtration methods known and proven to remove airborne particles, down to the size of 0.3 microns, and is almost exclusively used in medical, laboratory, and commercial applications where totally clean air environments are required for human health and safety.

filters are used for nuclear contamination, lead and asbestos abatement, surgical facilities, tuberculosis wards, clean rooms, computer rooms and other areas where clean and particle free air is essential. Since 0.3 micron size particles are the most difficult size particles to remove from the air (not 0.1 or 0.01 or any other number) and theypass easily into the body's respiratory system, (RSP) they are specifically used in the testing and certifying of a "True" HEPA Filter. (Please note: "HEPA-Type" filters are lower cost, not as efficient, and not an equivalent to a "TRUE" HEPA filter. "HEPA-Type" filters are simple low cost impersonators of a "TRUE" HEPA filter.) Is 0.3 Microns Filtration Important? Particles that are0.3 micron in size are the most difficult particles to trap and contain within a filter. Also,0.3 micron particle, when inhaled, passes easily into the body's respiratory system so the body's natural defense system is more vulnerable to these small particles.

This is why ONLY "True" HEPA filters are recommended by Allergists and Doctors.A micron is a measure of length: "1 micron equals 1 millionth of a meter!". A particle that is 10 microns or less in size is not visible to the naked human eye. Examples of some common air contaminants and their size in microns: "True" HEPA filters provide a DRY environment and captured bacteria and virus will dry out because without moisture, there is nothing to facilitate their growth and keep them alive. Without moisture the bacteria will die. Bacteria can breed within the filter ONLY if the air coming into the filter is moist. Other methods for killing Bacteria within a "True" HEPA filter is if the filter has been SPECIALLY treated for killing bacteria OR there is a Germicidal (non-ozone) Ultra Violet light such as with the Airpura Air Cleaners or the Allerair Air Cleaners. Will a True HEPA Capture and Trap ALL Viruses?? NO, most all Viruses are much smaller than 0.3 microns and they can pass through a HEPA filter.

Some may get trapped by adhering to the HEPA media but can also break loose and return to the air. According to the EPA there is no standardized test available to measure the effectiveness of virus filtration. Is a "HEPA-Type" Filter the same as a "True HEPA" Filter? HEPA-Type filters look like a genuine"True" HEPA but have nonspecific filter efficiency for respirable size particles (RSP) (0.3 microns) anywhere from 25% to 95% whereas a"True" HEPA has a certified 99.97%efficient in capturing 0.3 micronparticles . (This info provided by Allergy and Asthma Network - Mothers of Asthmatics, Inc) Should I leave my HEPA air cleaner on all of the time? Leaving the unit ON even when you are away lets the unit constantly scrub the air. Also, if a unit is turned off for a long period of time and then turned back on, you may smell some of the captured particles within the HEPA and or carbon. You should ALWAYS leave a HEPA unit running 24/7. If you do turn it off for days and weeks you are best to also change the filters.

Most people's reasoning for turning it off is to save on electrical costs. This is why an energy efficient blower moter (low wattage) is the best! Is the HEPA Filter the Most Important Part of an Air Cleaner and are not ALL HEPA Air Cleaner Systems the Same? , all HEPA Air Cleaners ARE NOT the same! Care must be taken when choosing a HEPA Air Cleaner because the most important part of any HEPA Air Cleaner, and the most expensive part besides the "True" HEPA air filter itself, is the Power, Performance and CFM (cubic feet per minute) of the Blower or Fan motor. There is no sense in having a good filter media such as a "True" HEPA filter if the blower or fan motor is weak and/or of poor quality. Since a "True" HEPA filter has a high efficiency of 99.97% a strong fan motor is REQUIRED and ESSENTIAL because the efficiency of any filter is meaningless if the unit can not draw air to and into the "True" HEPA filter itself. Is a higher wattage unit mean stronger fan motor? The higher the wattage simply means the higher in electrical costs to run.
