Where This UV System Fits
The Microfilter UV-405 is designed for residential point-of-use installations where flow rates are low and space is limited, such as under-sink drinking water systems, refrigerator lines, ice makers, or dedicated faucet applications. It requires pre-filtration to remove sediment and reduce turbidity before UV exposure, as particles can shield microorganisms from UV light. This unit is compatible with Microfilter UV-405T120 or UV-405T220 ballasts depending on your voltage requirements. The 1/4" quick connect fittings integrate easily with standard RO system tubing and point-of-use filter housings. UV disinfection is one of four USFDA-approved methods for water treatment and provides chemical-free destruction of bacteria, viruses, and other pathogens by damaging their DNA and RNA. Keep the UV lamp powered continuously to maximize lamp life and maintain continuous disinfection.
Understanding UV Lamp Life and Timer Resets
UV lamps gradually lose germicidal effectiveness after approximately 9,000 hours or one year of continuous operation, even though the visible light remains on. The ballast includes a lamp change timer that will beep and flash at the end of the year, signaling replacement is due. You have a 28-day grace period during which you can snooze the buzzer up to four times by pressing the timer button, but the LED will continue flashing as a reminder. After 28 days, the buzzer will sound continuously and the red LED will remain solid until the lamp is replaced. To reset the timer after installing a new lamp, unplug the ballast from AC power, wait 15 seconds, then plug it back in while holding the timer button. A successful reset is confirmed by a three-second beep. Avoid turning the UV system off unnecessarily, as repeated power cycling shortens lamp life.
