What is HEPA?

Hepa is a term used to describe filters that are more efficient and considered as supreme in the filter operations. Hepa is a term used to describe filters as high efficiency particulate air purifiers. As considered under a hepa rating a filter will be considered to perform operations within a specific guideline. The guidelines mandated under these specifications that a filter would remove 99.97% percent of particulates that are larger than .03 micrometers from air as it is delivered through various passages. The applications for hepa filters can be used in hepa vacuums and air purification systems in a variety of settings.


The settings in which hepa is operational can be residential, commercial or industrial. Such applications will offer varying degrees in which a filter is rated and hepa is a standard and offers variances per application. In varying applications the hepa filters can be regulated under EPA and other guidelines mandated by the operating management teams. Management teams will most often be used in industrial applications.


Hepa ratings of equipment such as vacuums will warrant that the filters will perform to the standards that they are rated. Using equipment that is not hepa rated and in conjunction with a hepa filter can be more productive but will not enable the filter to perform at its optimum level of application. It is common in household appliances such as vacuums to find hepa filters that are compatible with various models that are not hepa rated. Hepa rated equipment that uses hepa filters will greatly enhance the performance and considerably remove more toxins and particulates while in operation.


Residential use of hepa vacuums and filters are most commonly used in application in which members of the households are prone to allergies or asthma. Normal cleaning practices can stir dirt and cause pollutants to become air born and cause allergic reactions. Using hepa vacuums and filters will trap contaminates and keep particulates from being recirculated through the exhaust. Port of entry to the intake area of a vacuum can also incorporate hepa features that will increase the performance of the equipment.


Hepa rated commercial applications can be use in populated areas such as stores and airplanes in which the air is processed through a purifications system. Hospitals will be able to employ the use of air purification systems that are hepa rated. Hospitals will use filters and systems that are more strictly in conjunction with the highest efficiency in particulate removal as possible. Cleaning the air before circulation can greatly depend on the types of units available and a sealed system will address issues in which filters or exhaust ports could potentially let particulates bypass. Several filters can be used in a greater density to increase the hepa value of an operating system.


Industrial applications of hepa equipment and filters will be used a varying degree of applications. Removing dangerous particulates from worksites and factory setting can be an important part of the industrial processes. In several applications, heavy construction and industrial processes will create dust and particulates that can be extremely harmful to individuals and the environment. Safety guidelines of sites and production or manufacturing facilities will incorporate to follow EPA guidelines that specific hepa options be used in compliance with regulated mandates.


The EPA can monitor various applications with air quality checking devices and breathing apparatuses that  will monitor air quality and dust particulates. The air quality is measured and the number of air born particulates is identified by chemical compounds, size, and variances. The specifications for clean air control will vary greatly by job and application and will have a varying degree in which contaminants can be indulged dependent upon their hazardous nature.


Some applications such as removing toxic lead based paints will have a zero tolerance regulation of contaminants that are allowable in the removal process. A hepa vacuum that is used for removal of hazardous material will be necessary to follow several hepa guidelines and steps in removal processes to insure that the mandates are followed safely.

Zero tolerance of air particulates containing lead can be controlled with the proper hepa equipment. The equipment used will be in accordance with wet/dry operations in which the area will need to be washed and removal applications will create dust.


By passing, any of the several Hepa recommendations in dust removal can have severe consequences if not followed. Hepa guidelines are placed by the EPA and monitored but units that are hepa rated are not directly tested by the EPA. This will value that the operators and employers that are intended to follow EPA guidelines insure that the hepa units are up to code and used properly with in the guidelines.
