Air filters remove particles such as dust and dirt, as well as other harmful contaminants, from the air. Many industries use air filters to purify the air in order to protect the health, safety and wellbeing of all persons. There are several different filters used, with the four most common described in more detail below.

Worker

  1. HEPA Filters
    HEPA (high efficiency particulate air) filters are among the most popular and well-known filters on the market today. HEPA filters eliminate 99.97% of contaminants in the air that are the size of 0.3 microns in size, which means that this technology is extremely effective at sanitizing the air. HEPA filters are found in a wide-range of industries, from residential properties to businesses to medical facilities and more. For the most part, HEPA filters are made up of fiberglass fiber mats, which are designed to collect particles as air flows through.
  2. Carbon Air Filters
    Carbon air filters make use of activated carbon to neutralize and/or absorb elements such as chemicals and gases. The filter serves to neutralize the chemicals and gases as they travel through the air filter – but carbon can also be enhanced in such a way that it actually absorbs these chemical compounds as well. Carbon air filters are ideal at removing cigarette smoke, and are suited to industries where chemicals are a concern.
  3. Ionic Air Filters
    Ionic air filters produce negatively charged ions as a means to attract particles that are present in the air. As these two entities come into contact, they are deionized and filtered out of the air. These filters, which are also called air ionizers, are common in commercial sectors.
  4. UV Light Air Filters
    The last type of commonly used filter is the UV light air filter. Harmful particles such as mold and bacteria are neutralized through the process of titanium dioxide being exposed to UV light. High intensity UV is capable of destroying the majority of carbon-based compounds, which means that these filters are commonly used in medical facilities alongside HEPA filters.
