What people are saying

Rated 1 out of 5 by from does not filter out lead - BEWARE This filter is not certified via NSF 53 and does not filter out lead!!!
Date published: 2022-07-26
Rated 1 out of 5 by from Barely lasts 2 months The only time the filter lasted 6 months was when first bought the refrigerator in 2018. After that the filter has only lasted 2 - 3 months. After this last filter change it’s barely lasted 2 months. There’s no way that my husband and drink/use 500 gallons of water. In such a little amount of time. Otherwise the fridge works fine and we don’t have any issues with it.

Rated 1 out of 5 by from No longer manufactured by 3M, barely last 2 months No longer manufactured by 3M, barely last 2 months before losing significant water flow. This product is so poor, that we've decided to install a reverse osmosis system in place of this. Not worth the money or time replacing these.

Does my LG water filter remove floride from my city water supply?

Asked by: Steve37
The LG LT500P® - 6 Month / 500 Gallon Capacity Replacement Refrigerator Water Filter is system tested and certified by NSF International against NSF/ANSI Standard 42. NSF/ANSI 42 filters are certified to reduce aesthetic impurities such as chlorine and taste/odor. They are not certified to remove fluoride. Fluoride, a chemical added to the water supply in many places to help reduce tooth decay, can be a challenge to remove from water. It cannot be removed by Granular Activated Carbon (GAC) or catalytic carbon which is what most refrigerator water filters are made of so most water filters don't touch fluoride. A reverse osmosis filtration system is a simple solution for removing fluoride from drinking water. The most effective way and cost-effective way to remove fluoride from your water is with a bone char filter or reverse osmosis system or a combination of the two. Bone char is a special type of activated carbon that is made from carefully selected and cleaned animal bones. Most animal bones contain a large amount of a compound called hydroxylapatite. This is a special form of calcium apatite that is especially attractive to fluoride. When bone char is exposed to water that contains fluoride, the filter exchanges the fluoride ions for hydroxide ions, removing them from the water. This type of filter can remove up to 90% of fluoride from drinking water. A Reverse Osmosis (RO) system can remove 85-92% of fluoride in your water. Essentially, reverse osmosis technology uses household water pressure to push tap water through the filtration process. Reverse Osmosis (RO) pushes water through a special membrane with very tiny pores that block nearly everything but pure water from passing through. Like bone char filters, RO is typically considered to remove 90% of fluoride. A combination of RO and a bone char filter may be your most effective treatment method...^IFV

I own an LG refrigerator and noticed a prop65 sticker on the packaging of the filters.  I read LGJoel's definition but it did not answer either question...the 2018 law requires the chemical to be posted if it can cause cancer 1:1K. Which chemical & where?

Asked by: MichiB
The California Prop 65 Warning Notice states that "THE MATERIALS USED IN OR ON ANY, ALL OR NONE OF OUR PRODUCTS MAY OR MAY NOT CONTAIN CHEMICALS KNOWN TO THE STATE OF CALIFORNIA TO CAUSE BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM." Because of the sheer number of listed chemicals and minimal amounts triggering warning requirements, there are countless goods or services in California that fall within the purview of California's Proposition 65. There are currently about 800 chemicals on the list which require businesses to provide a warning before knowingly and intentionally exposing anyone to any of the 800 listed chemicals. Additionally, a warning must be given unless the business can demonstrate that exposure to the chemical poses “no significant risk level” of cancer, or “no observable effect level” of birth defects or reproductive harm. There are certain chemicals in plastics that are on the list. Since the cartridges & units have plastic we are required by California to have the Prop 65 statement on any products to be able to sell them in California. (Note that alcohol and aspirin are on their list, and would require the warning as well. People ingest those "chemicals" every day.) Nearly all businesses in the state post similar notices on their premises, even when they are unaware of any listed chemicals being present. Warning signs are always posted at gas stations, hardware suppliers, grocery stores, drug stores, and medical facilities. Most government agencies, parking garages, apartment complexes, retail stores, banks, and restaurants also post warning signs because of the possibility of hazardous chemicals being present in everyday items, such as a car or a computer, or because tobacco smoke from a passerby might drift in through an open window. Some large businesses, such as utility companies, mail a Prop 65 notice to all customers each year to warn them of dangerous substances like natural gas or the sand used in sandblasting. The term “no significant risk level” means the level of exposure to the listed chemical every day for 70 years that would result in not more than 1/100,000.00 chance of developing cancer for an exposed person...^IFV

Why does the LG LT500P water filter contain a Prop 65 warning? What chemical does it contain that is known to cause cancer? 

Asked by: HeatherB123
The Prop 65 warning on the LG 6 Month / 500 Gallon Capacity Replacement Refrigerator Water Filter (Part # 5231JA2002A), Model # LT500P requires the State of California to publish a list of chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or released into the environment. It also requires the state to maintain and update the list at least annually. Prop 65 is a ballot initiative that California voters approved in November 1986 to address concerns about exposures to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known by its original name, Proposition 65 or simply, Prop 65. Second, it requires businesses to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical. This warning can be given in several ways, such as by labeling a consumer product, posting signs at the workplace, publishing notices at a rental housing complex, or publishing notices in a newspaper. A warning means that the business issuing it is complying with Proposition 65’s requirement to identify the presence of one or more listed chemicals, even in trace amounts. Proposition 65 regulation leaves the determination of providing a warning to the business. The warning regulation does not explain how a business can assess if a warning is appropriate and it does not mandate businesses to perform testing. Businesses decide whether to put warning labels on their products based on their knowledge of the types of chemicals in them. Manufacturers are not required to provide the OEHHA with any information about the products. That means the OEHHA doesn’t know which chemical the warning refers to, how exposure could occur, or how much of the chemical a consumer is likely to be exposed to. The complete list can be found on the California Office of Environmental Health Hazard Assessment (OEHHA) website. The “Prop 65” warnings are only required under California law. Prop 65 standards are among the most stringent standards in place anywhere and are often far more stringent than federal standards. Many dietary supplements contain substances that require a warning in California. One vitamin that requires a warning above a certain level is Vitamin A. Coffee could soon come with a Prop 65 warning. Labels warning that a product contains compounds that may cause cancer, birth defects, or reproductive harm are now required on many household items, electrical wires, jewelry, padlocks, dishes, flashlights, pesticides, cosmetics, skin care, at restaurants and fast food chains, etc. sold in California. But people all over the country see these Prop 65 labels because many companies put them on all items that contain these chemicals, even if they’re sold in other states. Aspirin and aloe vera are on the Prop 65 list. Even schools in California and Starbucks have the Prop 65 warning on their doors. Companies that sell in California choose to label their products as a precautionary measure to avoid potential lawsuits, even when it is not necessary...^IFV
