UV bulbs are low-pressure mercury lamps that are used for germicidal purposes. The germicidal effect is caused by the emission of light that destroys most waterborne viruses, molds, yeasts, and bacteria. Some air purifiers feature a UV bulb, where air passes through the UV lighting to kill off the microorganisms in the air.
The light from UV bulbs is safe for people to be around; in fact the Centers for Disease Control (CDC) even suggests using UV lighting to prevent the spread of various diseases, such as influenza. People with damaged immune systems will benefit from utilizing UV lamps in their homes; as it decreases the chances of getting sick.
There are various UV lamps available on the market at present, but before purchasing one, you have to know a few facts regarding UV bulbs. These facts will help you decide which bulb is suitable for your home and your needs. One of the issues is the effectiveness of the UV bulb; according to manufacturers, the effectiveness of a germicidal UV bulb decreases, the longer it is in service.
For maximum effectiveness, the ultraviolet bulb should be replaced every six months, or at least once a year. Bulbs from Purely UV are guaranteed to run for at least 8,000 hours. The frequent on/off switching of the lamp decreases the lifespan of the UV bulb as the electrical current surge wears out the elements within the bulb.
The UV bulbs must also be handled with care, especially if you’re touching the glass part of the bulb. The oil in your fingertips can create a dead space on the bulb’s surface, which can diminish its lifespan. Check the manufacturer’s manual to find out the proper handling techniques, and all safety precautions.
