Some UV filters act as UV screens absorbing the harmful UV light. They are opaque and protect both food as well as the packaging material. Other UV screens are based on organic compounds and act as ultraviolet degradation inhibitors (p.38,[1]). Apart from being used in polymer based materials, UV filters are added to printing inks.
Clarity refers to the quality of clearness of an object,the clarity of picture frames tends to be reflected by the amount of light it lets through. Glass lets through on average 80% of light, and Plexiglass lets through around 90% of light. Although scratch resistant, Plexiglass is more prone to scratching than glass.
Fortunately, the higher energetic part of UV-B; 280 – 295 nm, is filtered by the stratosphere and does not reach the earth’s surface, UV-A (315 – 400 nm), has energy between 389 and 300 KJ mol-1 and is less harmful for organic materials than UV-B. Visible (400 – 760 nm). and infrared (760 – 2500nm.)

HVAC UV lights are relatively affordable, especially compared to air filtration systems like air purifiers and filters. The initial cost of installing HVAC UV lights is between $200 and $600 for coil sanitizing lights and between $250 and $700 for air sanitizing lights. These estimates include equipment and installation, although labor rates
