The A1 5-stage water purifier uses advanced ultraviolet technology to sterilize water and provide safe, drinking water. UV rays penetrate cell walls and destroy them, leaving you with water free from bacteria and viruses.

No more frequent visits from strangers delivering water to your house. With Smart UV Alerts, you're sure your water stays safe. The smart control automatically tracks your water use so that filters and lamps are changed not too early nor too late. Suitable for areas using city water with low TDS. DOH Registered
