Always Clear and Clean Water

The LG PuriCare™ Water Purifier uses a 4-Step Multi-Filter to remove heavy metals for clean water.

*In November 2021, a filter for the model (WS510SN) was requested to the Korea Environment and Water Research Institute and the certificate was issued by the Water Technology Certification Institute in accordance with Article 21, Paragraph 5 of the Drinking Water Management Act and Article 10, Paragraph 10 of the Enforcement Rules of the same Act. As a result of a quality inspection report, 7 types of heavy metals, 19 types of organic chemicals, 4 types of pesticides, 1 type of microorganism, and 4 types of mandatory water purification performance items were removed above the standard.
**Experiment results may differ in actual usage environments.
***7 Heavy Metals: mercury, lead, arsenic, cadmium, aluminum, iron, and copper.

Stay Carefree

Our completely sealed stainless cold water tank creates fewer water stains and bacteria than a conventional plastic tank.

Table showing that stainless steel tanks produce less water and germs compared to conventional plastic tanks.

*The model (WS510SN) was requested to Pukyong National University based on the swab test method to determine the bacterial propagation values. Plastic and heat-treated and polished stainless steel specimens were immersed in tap water with a test bacteria ?concentration of 10^7CFU/ml and left for 15 days. This is the average value of the number of bacteria in the biofilm formed on the surface of the specimen on the 2nd, 5th, 10th, and 15th day after treatment, and may vary depending on the actual use environment. (Tested by Pukyoung National University, February, 2012.)
** Tested bacteria: Listeria monocytogenes ?(low-temperature bacteria that grows below 10℃)
