Our American Water Service PT-20 Replacement UVC Light Bulb can be used as a 100% compatible lamp with the germicidal UV-C sanitizer model:

• PurTest PT-20

Note: CureUV.com stocks generic products that are 100% compatible with the original equipment.

The 39-watt water treatment bulb features four pins on a single end and is compatible with germicidal OEM water disinfection filters, ultraviolet water purifiers, and UV sanitizers. This germicidal UVC bulb comes with a 12-month sterilizing property and must be replaced after this period for maximum effectiveness. The high-quality light bulb comes with a lifespan of up to 10,000 hours and is set in non-ozone glass.

Researchers are of the opinion that when water passes through CureUV’s germicidal UV light it deactivates the genetic material of the microorganisms and makes them incapable of multiplying. The UVC light bulb emits a peak UV output of 253.7nm which is fatal to microorganisms such as viruses, bacteria, protozoa, and other harmful pathogens. Ensure your water is clean and safe with the American Water Service PT-20 Replacement UVC Light Bulb.

This bulb is available with a shatterproof coating that in case of damage keeps the lamp glass from falling into the unit where is installed. This results in an easy way to dispose of glass if it shatters. You can select this shatterproof option above.

Do I need shatterproof coating?

Although shatterproof coating can lower the intensity of the UV-C bulb by as much as 15%, it is recommended for applications in which it is crucial to avoid potential glass breakage at all costs. These applications include but are not limited to food processing and medical institutions. However, if glass breakage would be inconvenient but not catastrophic, skipping the costly shatterproof coating is quite alright. After all, we do not use shatterproof coating with our glasses and plates at home.
