Air Purifiers That Remove Black Mold

Black mold, commonly of the Stachybotrys strain, can grow in moist environments, including homes. While so-called "toxic molds" are not actually toxic or poisonous, they can produce trace amounts of mycotoxins and particularly affect people with compromised respiratory systems. The Center for Disease Control recommends, above all else, maintaining a low humidity level to avoid mold growth. In addition, you may wish to invest in an air purifier to reduce any airborne mold particulates and avoid their spread.

HEPA Air Purifiers

Black mold can accumulate in any areas with high moisture levels.

HEPA, or High Efficiency Particulate Arrestor, filters can help to neutralize any black mold in the air. HEPA filters are among the most efficient filters available, removing particles measuring as little as .3 microns at an efficiency of 99.97 percent. First developed by the Atomic Energy Commission during World War II, HEPA filters come recommended by the U.S. Department of Homeland Security for a range of filtration purposes. In addition to mold spores, HEPA systems remove dust, pollens, many bacteria, allergens and dust mites. However, HEPA filters are not highly efficient at removing particles from throughout a room, as they only filter what is drawn through them. Also, any microorganisms captured by the filter can continue to reproduce within the filter.

Ionizer Air Purifiers

An ideal pairing with a HEPA filtration system, an ionizer causes the finest airborne particles to magnetically adhere together, making them easier to filter. In addition, the ionizer is more effective than the HEPA filter at ionizing and removing particles from across a room. Once the particles are ionized, they become heavier and "fall out" of the air you breath. Ionizers are effective at removing extremely small particles, measuring as little as .01 microns. They can also neutralize cigarette smoke and chemical fumes. However, ionizers alone cannot collect most airborne particles, remove odors or kill germs or fungi.

Germicidal UV Lamp Purifiers

Especially if used in tandem with HEPA and ionizer technologies, germicidal UV lamps offer further air purification. The lamps' UV rays destroy any microorganisms, including germs, viruses, bacteria and molds. The Center of Disease Control recommends UV Light radiation to reduce disease. However, if used alone, the lamps do not affect particulates, chemical fumes, cigarette smoke and some odors.

Activated Carbon Air Purifiers

An activated carbon air purifier filters the air by using a network of molecular-size absorbent pores. The individual pores attach to all kinds of particulates, including chemical fumes, gases, cigarette smoke and odors. Once captured, the particles cannot return to the air. However, the filtration system does not remove allergens such as dust or some microorganisms. Like HEPA filters, activated carbon technology relies on particles passing through the filter to work.
