Output Life
It is important that lamps be replaced when the ultraviolet output falls below minimum requirements for protection. Even though
a lamp may appear to be operating satisfactorily because it still maintains the blue visible glow, the ultraviolet output may be
significantly reduced.
Cleaning
Lamps should be wiped with a clean cloth dampened with alcohol or ammonia and water in order to eliminate oil, dirt, and
fingerprints for maximum ultraviolet output. Conditions of the application will dictate how often lamps need to be wiped, however,
it is recommended to clean the lamps every 6 months.
Summary
With tighter home construction, indoor air quality has declined dramatically. Indoor air is laden with invisible bacteria, viruses,
toxins and molds. Filtering systems offer little or no solution because these airborne contaminants are so small they pass through
the filter or simply collect on the filter medium, creating a breeding ground. Recirculated air contains millions of disease and
allergy-causing microorganisms which not only live in the air, but are multiplying with each cycle through the system.
Ultraviolet radiation (UV-C) replicates the natural outdoor purification system of the sun by destroying the allergy and disease-
causing microbes living and multiplying in indoor air. Ultraviolet radiation is a safe, cost-effective method of purifying indoor air.
By itself, or in
combination with a HEPA or like-quality filter, it is the most effective way to reduce airborne bacteria and the health risks they
represent. The result is a clean, safe, healthy home environment.

Impact of Dust on Output
To maintain maximum benefits, UV lamps should be replaced annually.
Lamps should be located downstream of the filter to maintain lamp cleanliness and efficiency.
