The Aquasana AQ-STD-UV brings powerful, whole-home water protection with ultraviolet purification designed to neutralize the microorganisms you cannot see. Independently tested to NSF/ANSI Standard 55, this UV system sterilizes 99.99 percent of viruses and bacteria, along with 99 percent of chlorine-resistant cysts, giving your home a reliable final defense against harmful pathogens.

This system is especially valuable for homes on well-water, where microbial contamination is more common, but it is equally effective for anyone who wants added confidence in the water flowing through every tap. Using advanced UV lamp technology, the purifier emits controlled ultraviolet light that targets microbes at a cellular level, preventing them from reproducing and safeguarding your water without adding chemicals or affecting taste.

Maintenance is simple. The unit includes an audible alert and a digital countdown timer that remind you when it is time to replace the UV lamp, and replacement bulbs are easily accessible on Amazon under ASIN B074R2KCVN. The AQ-STD-UV works as a stand-alone solution or as part of a larger Aquasana whole-house filtration setup, making it a flexible choice whether you want full-home sterilization on its own or enhanced purification paired with sediment or carbon filters.
