Among common air purifier types, only one has been proven to truly work. After years of testing and collecting thousands of customer reviews, we only recommend HEPA air purifiers. HEPA stands for High-Efficiency Particulate Air — which is the safest, most sophisticated and effective air purification technology available. HEPA Air Purifiers are an Effective Solution to Indoor Air Pollution. HEPA air purifiers are designed to help eliminate free flowing particles in the air. Although these particles are not visible to the human eye, they can cause great health risks. Each HEPA air purifier contains a high-efficiency filter that captures 99.97% of particles that pass through the filter, ranging from tiny particles as small as .3 microns, to the larger particles that make up most common allergens. The percentage of particles removed from an air purifier is also dependent on the design and air flow construction of the air purifier itself. Air purification devices and technologies such as electrostatic air purifiers or ion generators do not produce efficient filtration, and generally only filter roughly 30 percent of particles and contaminants.

A HEPA air purifier works more effectively than an HVAC system filter, of which most people only have one, or perhaps two in their home. HEPA HVAC filters that are changed frequently are still advantageous to have, but alone they are not an efficient solution to clean the air in your home. HEPA air purifiers consistently outperform HVAC filters alone. Because air purifiers are portable, they are able to target specific areas in your home. For instance, an air purifier unit can be placed in a bedroom, where most dust mite debris collects and where we spend over one-third of our lives. Overall, the filtration efficiency of an HVAC filter used alone is significantly lower, especially given the fact that it is not mobile or powerful enough. Nor does it provide removal of any additional concerns that HEPA air purifiers can target, such as nasty odors or gases. After years of testing experience and thousands of customer reviews, we stand behind the best HEPA air purifiers that utilize additional technologies, such as UV lights and ionizers.

Both target much smaller pollutants and particles (including germs and bacteria) than HEPA air purifiers alone, making an excellent combination. Anyone can benefit from HEPA air purifiers. The air we breathe is critical to our health, yet the place we call “home” is 2- to 5-times more polluted than outside air. Our houses and offices are teeming with microscopic contaminants that can make us sick, and anything we breathe in can affect both our lungs and heart. Utilizing a HEPA air purifier is like having an extra boost to your immune system. Depending on the technology used, the HEPA air purifiers can help shield your body from various allergens, smoke and even bacteria. Overall, HEPA air purifiers promote a higher quality of life, protecting the health of children, the elderly and other vulnerable populations with weakened immune systems. It can even reduce costs associated with respiratory disease. The National Institute of Environmental Health Sciences held a study which found that “people living in the more polluted cities had a higher risk of hospitalization and early death from lung cancer and other respiratory diseases than those living in the less polluted cities.”

Air quality has never been more important. sharp air purifier placementTherefore, a quality air purification technology like HEPA is the perfect solution to relieve your body of environmental harm and the stress it causes. will air purifiers help with hazeCountless customers who have purchased HEPA air purifiers have seen significant improvements in their indoor air quality, and more importantly in the quality of their lives.air purifier stockists australia Browse All HEPA Air PurifiersThe history of the HEPA (High Efficiency Particulate Air) filter is one of the most interesting tales in American history. Many people may be surprised to find out, for example, that the filter was developed under the sponsorship of the Atomic Energy Commission and in connection to the Manhattan Project.

Keen on developing the atomic bomb before Nazi Germany did, the US was nevertheless cautious about exposing its scientists and soldiers to the radioactive particles expected to be given off during a nuclear explosion. To protect those working with this new horrifying technology, an air filter was designed that could intercept 99% of particles (as small as 0.3 microns) from the air; although it did not meet its original intent, the device did work to protect against fine-particle air pollution. Thus was the HEPA filter born. Although efficient from the beginning, the air filter was bulky and expensive to produce and was, for the most part, reserved (against contamination) for pharmaceutical companies, research labs, hospitals, and military facilities. In time, however, it was designed small and affordable enough to be used in home settings. Especially useful for people suffering from breathing diseases such as asthma, allergies, and Multiple Chemical Sensitivity (MCS), and for people who wish to avoid developing such problems, HEPA air filtration devices have come a long way in terms of technological advancement.

Some HEPA air purifier products, for example, using a combined electrostatic and mechanical filtration process, can trap 99.97% of microscopic particle, odor, and gas pollutant contamination. In fact, the latest models can intercept such strong allergens and irritants as pet dander, smoke, tobacco, mold, bacteria, viruses, dust, pollen, insecticides, laundry detergent, paint fumes, perfumes, hairstyling spray, and air fresheners without the additional use of UV bulbs and chemicals. Another way that HEPA air filtration has been made better is with the use of chemical absorption technology. In addition to activated carbon, for example, other chemicals can be used in the filtering process that can help absorb dangerous toxins. Two such purifying chemicals are Zeolite and potassium permanganate. As for how HEPA purifier filters work, well, contrary to popular opinion, they do not work like membrane filters, allowing only particles that fit through the smallest openings to come through.

Instead, HEPA filters, targeting particles at the microscopic level, work by trapping or getting to pollutants to “stick” to the special fibers (which are stacked in layers) in one of three possible ways: diffusion, impaction, and interception. Each of these processes involves complicated microscopic particle motion physics. It should suffice to say that HEPA filters act more like magnets than sieves or colanders. Although originally trademarked (1940), the term “HEPA” now refers to any efficient air pollution filtering system or device, according to specific filter ratings given by authorized agencies. HEPA filtration is one of the frontline defenses against airborne diseases, such as tuberculosis, the flu, and respiratory infections. For that reason, it is highly depended upon in healthcare facilities, as well as in medical research labs and in nanotechnology. This fine-particle-filtering technology is also useful in the fight against asthma and airborne allergies. With that in mind, the best vacuum cleaners today use HEPA filtration technology.
