Air Purifiers - Which are best for Bacteria and Virus Problems

Colds, flu's and other viruses are usually spread through microorganisms that become airborne. The microorganisms are then transmitted from one person to another by breathing in the air indoors that contains the contaminant. The spread of bacteria and viruses that are airborne can easily happen inside a home due to the confinement of air. Since homes are sealed completely tight for climate and safety purposes, the air that is contained inside a home cannot escape from the residence. If this home is contaminated with microscopic bacteria and microorganisms, they will simply re-circulate throughout the home because they have nowhere else to go. With the microorganisms re-circulating through the indoor air, it is apparent that the residents inside the home will breathe in the contaminated air. By breathing in air that contains these microorganisms or bacteria, residents are at a high risk of catching a cold or flu. Although all people are at risk for catching a cold or flu, young children, elderly people or residents with a weaker immune system are more at risk to contract an illness from airborne microorganisms. In order to eliminate these microorganisms and stop them from re-circulating through a home's air, air purifiers can be run inside the home to remove these particles. The best air purifiers on the market that specialize in defeating the spread of bacteria and microorganisms are any models that use a HEPA filtering system to clean the air.

The Allerair Exec UV is one unit that is effective at removing microorganisms and bacteria from indoor air. This unit contains a pre filter, HEPA filter and activated carbon media. These three stages of the filtering system are present to ensure the elimination of all particles, odors and fumes from the air. The unit also contains a germicidal ultraviolet lamp. The presence of a germicidal UV lamp can help air purifiers to kill any airborne bacteria or germs that may be present in the air that is taken into the unit. The germicidal lamp inside the unit is a 10 watt bulb that is able to kill most microorganisms and bacteria in the air that pass through the air purifier. Air purifiers that contain this UV lamp have become popular not just because of their effectiveness at removing these harmful bacteria from the indoor air but also because the lamp usually lasts about one to two years before it needs to be replaced.

Consumers who are not interested in purchasing a unit such as the Exec UV with the germicidal lamp may want to look into air purifiers that are equipped with a regular HEPA filtering system. A regular HEPA filtering system still specializes in removing particles and microorganisms from the air. The HEPA filter is able to trap even the smallest of particles and remove them from the air before they are released. Therefore, air purifiers that simply have the HEPA filtering system are still efficient at destroying the harmful viruses and bacteria that are present in the air.

The spread of viral infections, colds and flu's is something that all homeowners should be concerned with. The health of residents inside the home and the prevention of the spread of bacteria is an important issue and should be taken seriously by homeowners. The use of air purifiers that contain a HEPA filtering system or specialty air purifiers with germicidal lamps can be helpful for the quality of indoor air. With the use of one of these air purifiers, a home's indoor air can be safer and healthier for the residents to breathe.
