UV or Ultra violet light is one of the wavelengths emitted naturally by the sun. Though these waves are invisible to the human eye, they are all around us outside. As the sun emits these waves, they radiate pollutants in the air. UV-C wavelength destroys viruses, molds, bacteria, mildew, yeast, and algae by breaking through the microbe and causing its death. Do you realise now how good your sun dried laundry smells?

Thus UV light is a natural air purifier, capable of killing yeasts, molds, and viruses. And the best part is UV light is found in sun and hence it is free for all to use!

Ah… but most people live indoors – not out in the sun and hence they cannot take advantage of this free natural source! Therefore, a way must be found to use this naturally occurring air purifier in the home. This is where UV air purifiers come in to play. These air purifiers can help in detoxify the air in your home, though it is important to note that they won’t remove particles from the air.

Taking Advantage of UV Light
Ultra-violet air purifiers are usually installed in metal air duct systems, as exposure to eyes is very harmful. The faster and more often the air system is circulating, the more effective the UV air purifier will be. There are plug-in air purifier models available that make use of multiple filter systems (HEPA and carbon) in addition to a UV light stage.

Multiple filter + UV stage air purifier models start at about $600. Air duct installed systems, usually offering UV only or a UV / HEPA combination, start around $300 with an average model costing $700 plus installation. You may think it is steep but UV air purifiers have no odor and are silent unlike most other purification systems. There is still some noise inherent in running forced air through a home or office but that’s all. Generally light bulbs usually need to be replaced every 15 months if the UV air purifier is ran 24 hours a day.

Drawbacks to UV Light
There are some situations that would render a UV air purifier virtually useless. If the air doesn’t circulate in a room or building, or if the air circulates very slowly, a UV light purifier won’t be able to do its job. This is because UV light can only kill contaminates that are very, very close to the light bulb. A UV bulb is only 60 percent efficient at .4 inches from the bulb and only 20 percent effective at 2 inches from the bulb.

Besides, do you know that United States Government buildings, including schools and hospitals, are required to have UV air purifiers installed in HVAC systems? This clearly demonstrate that UV light air purifiers are effective in removing and destroying the pollutants in the air.

Thus if you can afford it, you should invest in one to give yourself and everyone in your home air that is safe and clean to breathe.

A good air purifier helps in purifying the contaminated air by freeing the air from pollutants.

People living in a congested home and locality usually live in contaminated air. Environmental studies have revealed that the air inside the house is dirtier than the air outside.

Air purifiers are extremely beneficial for people suffering from allergies and asthma. Dust, pollen, pet dander and molds are some of the allergy inducing particles. A home air purifier not only effectively removes these harmful particles, but also provides protection against hazardous smoke particles and airborne gases. The air purifiers convert the dirty and contaminated air into clean air and provide protection against second hand smoke.
Air purifiers alleviate asthma, and some completely removes the allergens causing asthma by providing superior quality air. By reducing the dust floating in the air, filtering second hand smoke, and purifying the air of chemical pollutants, car exhaust fumes or other contaminants, air purifiers improves the living condition of asthma sufferers. Even little children, especially newborn babies and old people, suffer respiratory disorders due to the bad condition of the air we breathe. Bacteria, viruses and other types of microorganisms cause pneumonia and tuberculosis, and sometimes certain diseases that may lead to death if not treated properly.
An air purifier reduces and sometimes eliminates contaminants in the air. Different techniques like filters, absorbents like charcoal, and electrostatic charges are used. The ionic air purifier is the newest type of cleaning device to make your home germfree. Other types of air purifiers are air purifiers with HEPA air filters. The additional setups include germicidal UV light and the emission of ions into the air to react with contaminants, making them harmless enough to breathe. The cost of filters and how many times you will need to replace them should be well researched before buying them.
Air purifiers will help purify the air in your vehicle. Vacuum your vehicle regularly as the seats can harbor dust mites, insect parts, pollen, molds, and pet dander. When the conditioner is on, always circulate the air rather than pulling it from outside. A good air purifier can reduce all kinds of irritants and allergens, and circulate clean sir throughout the car. The quality of your sleep and health can be improved by using a good air purifier. Air purifiers are used in many restaurants and other business houses, which allow smoking, to improve the air quality and keep it clean and fresh.
