An article in Air Quality, Atmosphere & Health noted that for comprehensive air cleaning, additional filtration methods are often required. -
Requires Regular Bulb Replacement:
The bulbs in UV-C air purifiers have a limited lifespan and require replacement every 12 months, depending on usage. According to the product specifications, failure to replace bulbs can reduce the device’s effectiveness considerably over time. -
Safety Concerns Regarding UV Exposure:
UV-C light can pose risks of skin and eye damage with direct exposure. Manufacturers often advise against positioning purifiers in areas where direct light may reach. The American Conference of Governmental and Industrial Hygienists (ACGIH) recommends adhering to safety guidelines to mitigate exposure risks. -
May Not Be Suitable for All Environments:
UV-C air purifiers may not be ideal for all indoor settings, especially in spaces with vulnerable populations, such as the elderly or immunocompromised individuals. Situations where filtration requirements are high may also necessitate using additional air purification technologies.
