Air Purifiers

Working in an industrial environment can often result in negative effects. Exposure to dust and other types of air particles may cause employees to have mild respiratory problems or allergies. The air is often fouled by allergy-inducing particles that are known as allergens. Allergens can show up in the form of dust or pollen as well as pet dander and mold spores. In industrial settings, hazardous smoke particles and airborne gases may also be present in the air.

Hence, air purifiers become a necessary tool in such conditions. Air purifiers employ various techniques to purify the air. Some of the more common ways of purifying the air are by are using filters, electrostatic charges or substances like charcoal that absorb the dust and other particles. Additional ways of purifying the air include the use of germicidal UV light and the release of ions into the air to react with the contaminants, which makes them harmless enough to breathe.

Although air purifiers are designed to make the air as clean as they possibly can, no commercial air purifier is can keep a room completely dust free. This is important in places such as hospital surgical rooms or in sensitive manufacturing like optics or computer processors.

Air purifiers are used in a wide array of commercial and industrial applications. Air purifiers not only remove toxic gases and chemical fumes from the air, but they are also designed to kill various kinds of bacteria and viruses. When choosing an air purifier, one must keep in mind whether the purifier is needed to remove dust for employees who are prone to allergies and asthma attacks. Air purifiers not only cleanse the air of harmful particles, but they can also improve the quality of air inside an industrial unit, thus enhancing the productivity of the personnel.

There are several factors to consider when buying an air purifier, including its visual appeal, the unit’s noise level, and the frequency of air filter replacement. The most popular type of filters used for air purifiers are High Efficiency Particulate Air Filters (HEPA filters) as manufacturers must meet rigid government requirements for these filters. HEPA filter requirements state that the filter must be able to filter out approximately 99.97 percent of air pollutants of down to 0.3 micrometers in size.

Clean Air Delivery Rating (CADR), is a standardized indicator of air purifiers stack up against each other. The higher the purifier is, the stronger the power of purification. CADRs are rated by the Association of Home Appliance Manufacturers (AHAM), and are based on stringent requirements.
