Protection from Ultraviolet rays/sunlight
We cannot filter too much UV rays. This is the work of ozone in our atmosphere.
A skylight filter reduces the bluish tint in photos taken outdoors, while a UV filter blocks ultraviolet rays that can cause haziness. UV filters are more effective in protecting the camera lens from harmful UV rays.
A UV filter is used primarily to reduce the amount of ultraviolet light that reaches the camera sensor. It helps improve image clarity, reduce haze, and protect the lens from scratches, dust, and moisture. However, the impact on image quality may be minimal with modern digital cameras, so some photographers choose not to use UV filters.
Yes, it is the only thing. It filters the UV.
Ordinary glass will filter out UV rays by itself. So you will get the combined filtering of the glass and the ozone reducing the UV ray intensity.

UV light is not necessary for a water filter to work effectively, but it can be a helpful additional feature for killing bacteria and viruses in the water. UV light can provide an extra layer of protection in ensuring that the water is safe to drink.
Clear glass does not effectively filter UVB rays; it allows a significant portion of these rays to pass through. Unlike UV-C rays, which are completely blocked, UVB rays can penetrate clear glass, resulting in potential skin exposure indoors. If UV protection is desired, specialized UV-filtering glass or window films should be used.
No, sodium benzotriazolyl butylphenol sulfonate is not a salt. It is a synthetic ultraviolet (UV) filter used in sunscreens and other personal care products to protect against UV radiation.

A skylight filter reduces the bluish tint caused by ultraviolet light, while a UV filter blocks ultraviolet rays. Skylight filters can enhance colors and reduce haze, while UV filters primarily protect the lens. Skylight filters are more beneficial for improving photo quality as they can enhance colors and reduce haze, while UV filters are mainly for lens protection.
A UV air filter will be helpful in your home to catch pollens and dust for those who have allergies. It keeps the air clean and for a decent sized house I would recommend a Germ Guardian.
