HEPA air purifiers are included in a category of air filtering devices that are used to improve the quality of air as it circulates within indoor structures. The HEPA designation, which stands for High-Efficiency Particulate Air, simply means that an air purifying product has satisfied the efficiency standards that have been specified by the United States Department of Energy. In other words, a HEPA air purifier is required to be able to remove more than 99 percent of particles that are larger than 0.3 micrometers. This type of air purifier is often sought by families who need to reduce allergens in their indoor environment, whether their air purifying needs are localized to one room or relevant to the entire home.
The first HEPA air purifier was created in the 1940s. This invention was intended as a means of preventing the spread of radioactive particles through the air. In more recent times, HEPA filter air purifiers are often made of fiberglass fibers between 0.5 and 2.0 micrometers thick, which are randomly arranged into a mat. The fibrous mat in a HEPA air purifier traps particles from the air as it passes through the filter. In general, any airborne particles that encounter the fiberglass fibers will either stick to the surface of the fibrous material or become embedded in specific fibers. The effectiveness of this trapping action may vary depending on the speed at which the air is moved through the filtering system.
HEPA filter air purifiers have been increasingly recognized in recent decades as being beneficial to highly controlled environments such as hospitals and passenger airplanes, where the reduction of viral and bacterial matter is important. The best HEPA air purifiers are found in hospitals, medical centers, and other healthcare environments where infection control is a critical component of care. Typically, the best HEPA air purifiers that are used for medical facilities also use a component that involves ultraviolet light to destroy any infectious contaminants trapped by the filters. HEPA filtering processes are also used in the processing of computer chips, pharmaceutical drugs, and nuclear fuels, as well as in a variety of other industries.
When considering the purchase of new HEPA air purifiers for private use, consumers should consider the intended use of these devices in their homes. Private homes can be contaminated by a number of different substances, which are categorized as either particulate matter or gaseous pollutants. Particulate matter can include pollen, dust, bacteria, viruses, animal dander, and mold. Gaseous pollutants can include smoke, exhaust, and fumes from paint or cleaning products.

Since it is not always possible to completely eliminate contaminants from the home or control them through simple ventilation by use of open windows, HEPA air purifiers are recommended as a secondary means of improving air quality indoors. The best HEPA air purifiers are able to remove the majority of unhealthy particles from the air, particularly those that are allergenic substances. Among the other benefits of air filtration, using a HEPA filter in the home is believed to improve indoor air quality by significantly reducing the number of circulating allergens. Some studies have investigated whether HEPA filter air purifiers can offer medical improvements in individuals with cat allergies or symptoms of asthma.
Shopping for the best HEPA air purifier can involve carefully weighing each product’s price against its features, speed, and reputation. Most people are looking for a filter that can effectively remove pollen, dust, smoke, and animal dander from the indoor environment without excessive noise. Some experts say that the best HEPA air purifier will indicate how often to replace or clean its filter. When comparing available HEPA filter models, consumers are urged to check the MERV or “minimum efficiency reporting value,” in addition to looking at a model’s CADR or clean air delivery rate. For the majority of families, the best HEPA air purifier will be one that is stated to be effective for a larger area than they actually need, in order to gain maximum filtering efficiency with the least amount of incidental noise.
By some estimates, people in the United States spend as much as 90 percent of their daily lives indoors, where the level of air pollutants could be up to five times higher than outdoor pollutant levels. Given these statistics, consumers who are concerned about health issues regarding air quality would be wise to consider the purchase of a HEPA air purifying system, which has the potential to substantially improve the quality of the air that they breathe in their homes.
