These authentic Savio® replacement UV bulbs are for use with UVinex® clarifiers and sterlizers. These Savio UV bulbs can only be used with the newer UVinex™ UV filter which does not have a quartz sleeve. If you own an older version of the Savio UV filter with a quartz sleeve you need a different bulb, check your manual or contact us.
New "Twist & Lock" feature allows for easier installation and holds the bulb more securely in place.
* Bulbs are not warrantied as contributing factors such as input voltage fluctuation, age of original UV device electronics or power surges can cause the lamps to fail.
