The T1-2011A countertop water purifier combines carbon filtration with germicidal UV lamp. Effectively removes contaminants while improving taste and odor of drinking water. Installs to a sinks water faucet in minutes with the multi-purpose faucet connector. UV filtration: with the ultraviolet radiation between 240 through 290 nanometer, UVC penetrates the outer structure of biological contaminants and alters their DNA molecule to destroy and prevent replication. UVC technology is environmentally friendly and does not alter the taste, odor or pH value of the water. Carbon filter: by using an unique technique of wet casting process to combine carbon granule with fibers, the carbon cartridge is capable of absorbing a high amount of chemical carcinogens. Within the same amount of time, the T1-2011A can remove 5 to 10 times more contaminants than traditional granular carbon filters or carbon blocks. Also removes chlorine and lead while preserving beneficial minerals that are needed by the human body. Input voltage: 120V 60Hz. Power consumption: 0.6W (standby) 14W (operation).
