👉 The word "UV" stands for "ultraviolet". A filter that selectively absorbs UV light, reducing its intensity or killing bacteria and viruses on a surface. It's used in air purifiers to remove harmful UV radiation from indoor air before it enters homes. Detailed definition: Ultraviolet (U) is a part of the electromagnetic spectrum (e.g., visible light). Light with wavelengths between 400-750 nanometers, known as ultraviolet, includes blue and red light, which we see in the sun. It's responsible for generating sunlight on Earth. Filters are used to block UV light, so it reduces harmful rays, thus protecting your eyes from damaging UVA and UVB rays.
UV filters can be categorized into two types:
1.
Ultraviolet (UV) Filter:
This type is designed specifically to block ultraviolet light.
2.
Infrared (IR) Filter:
It's suitable for filtering out infrared radiation without blocking the UV light.
UV Filters are essential in ensuring your home or office environment stays safe and healthy.
