As an expert in air quality and purification, I have seen a growing trend in the use of air purifiers with UV light. Many people are turning to these devices in hopes of improving their indoor air quality and protecting themselves from viruses like COVID-19. However, as much as I understand the appeal, I must warn against buying an air purifier with UV light or any device that relies solely on UV light for purification. Let me explain why. First and foremost, UV light can be dangerous if not used properly. In fact, a study published in the journal Public Health Reports found that UVGI (ultraviolet germicidal radiation) is most effective when used in upper rooms with lamps mounted on the ceiling.
This method is not suitable for home use and can be harmful if not handled correctly. Furthermore, UV air purifiers are not as effective as they claim to be. While they may capture and destroy some airborne viruses and bacteria, they are not a reliable method of purification on their own. In fact, without the use of other proven filtration methods, these devices may even cause more harm than good. At Smart Air, a certified B-Corp social enterprise, we offer simple and practical air purifiers that are backed by scientific research. Our goal is to educate people on the dangers of air pollution and provide affordable solutions to protect their health.
We understand the appeal of UV air purifiers, but we also know that they are not the most effective or safest option. In addition to safety concerns, UV air purifiers must be carefully designed to prevent any plastic parts or insulated wiring from being exposed to the UV light. If not designed properly, these devices can actually emit ozone into the air, which can be harmful to our health. While UV air purifiers may seem like a better option for killing mold spores, bacteria, and viruses, they also have their drawbacks. For one, they can be quite noisy and may not be suitable for use in bedrooms or other quiet spaces. Additionally, attempting to purify air that moves too quickly through the device can be ineffective. So, are air purifiers with UV light worth it? In my expert opinion, the answer is no.
While they may offer some benefits, the risks and limitations outweigh any potential advantages. If you are looking to improve your indoor air quality, I recommend investing in a high-quality air purifier with a HEPA filter. These devices have been proven to effectively remove dust, smoke, and pollen from the air without any added risks. However, if you have a weakened immune system or are looking for extra protection against viruses, a UV germicidal lamp may provide some added benefits. Just be sure to use it in combination with a HEPA filter and follow all safety precautions.
