LG LT800P 6-Month Refrigerator Water Filter - Cleaner Tasting Water

Our review of the LG LT800P replacement water filter finds it best for households that want a straightforward way to improve drinking water and ice quality without fuss. Installed horizontally in compatible LG refrigerators, the filter's primary appeal is its certified contaminant reduction under NSF42, NSF53, and NSF401 standards, which gives peace of mind about reduced chlorine taste and odor plus many common contaminants. For people who prioritize safer, better tasting water on a predictable 6-month or 200 gallon replacement cycle, this filter delivers reliable performance and simple maintenance.

Key Features

• NSF-certified filtration: Certified to reduce chlorine taste and odor and a range of contaminants, providing cleaner water and ice for daily use.
• Contaminant reduction: Removes 99.99% of cysts and 99% of asbestos while reducing mercury, lead, benzene and other common impurities to improve water safety.
• Removes chemicals: Designed to lower levels of pesticides, detergents and some pharmaceuticals that can be present in tap water.
• Replacement cadence: Use for up to 6 months or 200 gallons to maintain contaminant reduction and consistent water quality.
• Genuine LG part: Sold as the genuine LG replacement part number ADQ73613401 and fits specified LG refrigerator models for proper horizontal installation.
• Carbon filter flush: New carbon-based filters require flushing up to about 2 gallons before regular use to clear loose carbon and ensure best taste.

Who It's For

This filter suits families and individuals who want a certified, refrigerator-integrated solution to reduce taste and odor issues and a wide set of contaminants without installing an external system. It is a practical choice for anyone using an LG refrigerator that specifies compatibility with ADQ73613401 or the equivalent part numbers.

Shoppers who need advanced filtration for heavy industrial contaminants, very high flow rates, or multi-year cartridge life should consider whole-house or specialized systems instead; likewise those who require an included cap or non-horizontal installation should verify compatibility before purchase.
