How to Replace your Water Filter

Always use new LG filters with your LG refrigerator. It is essential that the manufacturer's recommended installation, maintenance and filter replacement requirements be carried out for the product to perform as advertised.

Rated 4 out of 5 by from The perfect freezer When my original side by side died and I purchased this one, It had all the features I wanted but was I felt it didn't have the same amount of shelf space. Even when moving the shelves, I still never had the right sized or no more than three shelves. However, the freezer is a different story, my freezer is perfect, enough space for larger items, small items, 3 or 4 boxes of pizza on one shelf, wonderful. But the real test came when Hurricane Irma stopped by Georgia for a visit and we lost power for 23 hours. I instructed my family not to open the freezer and we didn't, and 23 hours later everything was still frozen solid. I didn't lose anything, not meat, not vegetables, nothing. Actually, only a few of my ice cubs melted. I simply pub the top half of the ice cubs in a pitcher, poured the others out, dried the bottom of the container and put the cubes that were in the picture back in and we were back in business.

if i have this inner filter: LG Original LT800P ADQ73613401 Refrigerator Water Filter Genuine do i need non genuine external filter (that u can buy on every store not something special) ? or they do the same job on the water coming out from ref kiosk?

Asked by: nisan
That will depend on the "non-genuine external filter" that you get. The LG 6 month / 200 Gallon Capacity Replacement Refrigerator Water Filter (ADQ73613401), Model # LT800P is an NSF/ANSI certified filter. To help address concerns about the safety and performance of products sold worldwide and marketed for treating household water supplies, NSF International developed several American National Standards covering a wide array of water treatment systems, including: • Filters (whole house, drinking water, and shower units) • Reverse osmosis systems • Water softeners • Distillation systems • Ultraviolet disinfection products and microbiological purifiers. To earn NSF certification, water treatment systems must undergo extensive testing to confirm that they meet the strict requirements of American National Standards. In addition to verifying that the system is structurally sound, NSF verifies that: • The contaminant reduction claims shown on the label are true. • The system does not add anything harmful to the water. • The product labeling, advertising and literature are not misleading...^IFV

What PH is the water the filter provide? 

Asked by: Ashleak
The pH value of your water indicates whether water is hard or soft and pure water has a pH value of 7. In general, water with a pH lower than 7 is considered acidic, and with a pH greater than 7 is considered being alkaline (basic).The normal range for pH in surface water systems is 6.5 to 8.5, and the pH range for groundwater systems is between 6 to 8.5. The LG 6 month / 200 Gallon Capacity Replacement Refrigerator Water Filter (ADQ73613401), Model # LT800P helps to reduce metal ions such as iron, manganese, copper, lead, and zinc that make the water acidic, however, the pH for that filtered water would have to be measured to determine its value. The ideal pH level of drinking water should be between 6-8-5, but the pH value can also be impacted by atmospheric gases and temperature so it has to be tested on a regular basis...^IFV

Will this part work for a system model ADQ73613402, emphasize on 02?

Asked by: Logan5
Part # ADQ73613402 is for a Kenmore Refrigerator. The LT800P is the LG 6 month / 200 Gallon Capacity Replacement Refrigerator Water Filter (Part # ADQ73613401) for LG Refrigerators. We would need some clarification on "emphasize on 02"? This is a water filter that filters contaminants in the water supply. 02 or Oxygen is not a contaminant!...^IFV

does this also filter the water that is used to make the ice in the ice maker?

Asked by: anonymouss01
We appreciate your interest in this filter. Most refrigerators will run the ice maker water through the filter, as well as that which runs to the water dispenser.
