The sun emits UV rays which are all around us here on Earth. UV-C rays are naturally filtered by our atmosphere. UV-A and UV-B rays are the rays that we need to protect our eyes from. Man made UV-C is completely safe when used properly.
UV-C is known as a disinfectant for air, water, and nonporous surfaces, which is why it’s so effective when integrated into your home’s HVAC systems. Precise levels of UV-C in air purifiers are strong enough to kill microorganisms, but these levels are not dangerous to humans. Purified air is cleaner and healthier than air that hasn’t been through a purification process.
