Air Purification

Dust, pollen, pet dander, mold spores, and dust mite feces can act as allergens, triggering allergies in sensitive people. Smoke particles and volatile organic compounds (VOCs) can pose a risk to health. Exposure to various components such as VOCs increases the likelihood of experiencing symptoms of sick building syndrome. Air purifiers are used to reduce the concentration of these airborne contaminants and are especially useful for people who suffer from allergies and asthma. They also reduce the need for frequent cleaning. Air purifiers use a small amount of electrical energy, causing a small amount of expense and environmental effect. Recent advances in technology have allowed for air purufication systems to aid in the reduction, containment and removal of health care acquired infections (HCAI) such as MRSA and CDIFF.

Typical forms of air purification include:

High Efficiency Particulate Air (HEPA) Filter which simply filters particulates through a mat of randomly arranged fibres from the air up to 0.3 microns in size.

Ionisation. Air ionisers are used in air purifiers, though they are not recognised to be particulalry efficient. Airborn particles are attracted to the electrode in an effect similar to static electricity. Heavier combined particles may fall out of the air to the floor and thus are no longer airborne.

Ozone Generation. Ozone can also be used for bleaching substances and for killing microorganisms in air and water sources. Many municipal drinking water systems kill bacteria with ozone instead of the more common chlorine. Ozone has a very high oxidation potential and has the ability to remove airborne odour and bacteria albeit that the levels required to remove airborne bacteria exceed those safe for humans and thus areas must be vacated when ozone generators are in use.

Close Coupled Field Technology (CCFT). Pulling air at up to 1,000 cfm through the CCFT achieving a 99.9% kill rate in one pass of particulates to 1 micron. Thus being capable of removing mould, bacteria and virus from the air.
