LG Water Filter: A Review of the Best Models Manufactured by LG

lg water filter

LG manufactures high-quality water filters for its various refrigerator models. If you own an LG fridge, you have the option to choose an authentic replacement LG water filter or a compatible model made by an independent brand. The quality and longevity of named brand filters is likely to be higher and more consistent than off-brand replacement cartridges that cost less up front. This appliance manufacturer only makes water filters for refrigerators and does not produce whole-house or under-sink filtration systems.

What Are LG Water Filters?

An LG water filter is an authorized replacement cartridge designed for specific refrigerator models. These filters are branded by the same manufacturer that designs LG refrigerators. These filters are very high quality, supported by a status indicator system, and provide cleaner, healthier and better-tasting water.

You will need to replace the water filter in your fridge at least every six months depending on the capacity of the model you choose. Most of the replacement filters LG makes are rated for a 200-gallon capacity and operational life of six months. Some models feature a 300- or 500-gallon capacity and last the same amount of time. After the capacity or period of time has been exceeded, users may experience a noticeable drop in the quality of water from the built-in fridge dispenser.

LG recommends prices for all of its water filters. Replacement cartridges compatible with most refrigerator series and model numbers are set at $49.99 with two-packs available for $90. This means that you can enjoy filtered ice and water from your LG fridge dispenser all year long for $100 or less. This is much less expensive than bottled water, filtered water delivery or many other home filtration systems that will also require replacement filters at least every six months.

Off-brand filters may not work as well as authentic replacement filters. Some customers report that these filters cost less, but that the taste of the ice or water produced is not equivalent to results with a compatible LG water filter. Others complain of a slight chemical taste in filters from independent brands, find that these cartridges do not last for the full six-month period or remark that the filter status monitoring system built into the fridge does not recognize these cartridges. If use of an unauthorized water filter damages your refrigerator, ice maker or water dispenser, this damage may not be covered under the terms of the warranty on the appliance.

Product Specifications

LG sells a variety of model numbers and sizes of replacement refrigerator water filters. You should consult the manual that came with your fridge when purchasing replacement filters to ensure that you select the right cartridges for the water filtration and dispensing system. You may also want to purchase a multi-pack of filters to save money and ensure that you are never without a back-up filter.

This filter has a larger capacity than other LG LT series filters but is still rated for use for six months. The cartridge is NSF-certified to reduce chlorine taste and odor and filter out many other types of particulates.

The LG LT 700P is a water filter designed for dispensers and icemakers on other LG fridge models including many units in the LFCS, LFD, LFX, LFXC, LFXS, LMX, LMXS, LPCS, LSFD, LSFS, LSFXC, LSMX, LSSB, UPFXC and UPSXB series. This model is designed to have a 200-gallon capacity as opposed to the LG LT 600P which provides 100 gallons more filtered water within a six-month period. Like the 600P model and unlike the 500P, this cartridge also installs horizontally.

Like other LG fridge water filtration cartridges, the LG LT 700P is designed to eliminate the taste and smell of chlorine in ice and water dispensed from a compatible fridge. This filter also works to reduce levels of asbestos, benzene, mercury and lead in drinking water. You should replace this filter model as soon as alerted by the filter status indicator or when you notice the quality of water lessening. The additional functions of this unit make it all the more important to purchase an authorized replacement LG water filter.

The LG LT 800P is designed to work with different LG fridge models than the preceding models. This six-month, 200-gallon capacity chilled water filter is compatible with units in the LMXC, LMXS,LNXC, LNXS, LPXS, LSC, LSXC, LSXS, LUPCX and LUPXS series. Confirm that the LG LT 800P is the right replacement water filter for your fridge by checking the owner's manual prior to making a purchase.

This fridge water filter for dispenser and icemaker reduces chlorine taste and odor, and removes many particulates such as iron and other chemicals and volatile organic compounds. This cartridge installs horizontally in compatible LG fridge models and will need to be switched out every six months. You may be able to purchase the LG LT 800P in a pack of two or more replacement filters for a small discount.

If you own an LG LMXS, LMXC, LFXS, LMXS, LFXC, LSXC, LSXS, LSFXC or LSXC series refrigerator, the LT 1000P water filter cartridge may be the right replacement unit. Double check your fridge manual before placing an order for this 200-gallon capacity cartridge rated for six months of use. The LG LT 1000P water filter reduces the presence of chlorine taste and odor in ice and chilled drinking water while also lowering levels of particulates such as asbestos, benzene, mercury and lead.

Like every other LG refrigerator dispenser water filter, this model is pharmaceutical grade and intended to promote health and safety. Most users consider this filter easy to install, high quality and a good value for its capacity, operating life, price and overall quality. Like all of the other LG water-filter cartridges with the exception of the LG LT 500P, this model installs horizontally in compatible refrigerator units.

This advanced three-tier filtration bundle including a carbon pre-filter, membrane filter and carbon post-filter is only compatible with fridge models equipped with LG's three-tier filter system. The recommended selling price for this bundle of three filter components is about $150, making these replacement filters the most expensive replacement cartridges available from LG.

If you own a fridge with three-tier filtration technology, you will enjoy some of the cleanest and highest-quality water with a regular investment in a new pre-filter, membrane and post-filter. It will cost approximately $300 to sustain clean water for a full year, making this option up to $200 more expensive per year than other LG water filtration systems. This method includes much more advanced filtration technology and resembles reverse osmosis systems. The overall quality of ice and chilled drinking water dispensed from your fridge may be worth the additional cost, especially if you live in an area with poor water quality.

Pricing

The manufacturer's recommended price for LG LT 500P, 600P, 700P, 800P and 1000P water filters is $49.99. You can purchase authorized LG filters from local appliance stores or online. Make sure that the filter you purchase is authentic for the best performance and quality. You can also trust that these cartridges will not void the warranty on your refrigerator. Off-brand filters are known to leak and underperform the compatible LG water filter for your fridge model.

Even though independent off-brand filters may cost substantially less, many users complain about chemical taste in the ice or water or a much shorter operational life than the right LG water filter for your refrigerator model. If you want to save some money and ensure that you will always have access to clean, fresh-tasting water, you can purchase a two-pack of LG water filters for your refrigerator.

The recommended price for these two-packs of water filtration cartridges is $90, which means that customers receive a $10 discount for buying two filters at once rather than one at a time as you need to replace them. This can also help you save money in case the price of these filters fluctuates within the year. A two-pack allows you to maintain the quality of the ice and water from your fridge dispenser for a full year without having to search for compatible filters in area stores or wait for a replacement you order online.

Conclusion

If you own an LG refrigerator with an ice and water dispenser, you should purchase the right model of authorized replacement water filter. Keep in mind that every filter model is not compatible with every fridge model. It is important to check the manual that came with this appliance before placing an order for replacement cartridges.

Every model of LG refrigerator water filter is designed for easy installation, regardless of whether the cartridge installs horizontally or vertically. Most LG water filters with the exception of the LG LT 500P install horizontally. If you have questions about proper installation, consult your owner's manual or online resources from LG or other owners of the same refrigerator model.

In general, you will need to shut off the water supply to prevent leaks during the filter change process. Twist the old filter a quarter-turn counterclockwise to remove. Insert the new filter and push it into the receiver until it stops. Twist the replacement filter a quarter-turn clockwise to install, and reset the water filter status display by pressing and holding the reset button for three seconds. Once you turn the water supply back on, your fridge will be ready to produce filtered ice and water for another six months.

Depending on your fridge model, the capacity of your filter and whether the filter installs horizontally or vertically, you may need to perform slightly different steps to correctly install a water filter in an LG fridge. The filter-monitoring system built into the unit should recognize authorized LG cartridges but may not display accurate status updates for off-brand filters. Choose a compatible LG water filter to enjoy the best-tasting water straight from your fridge dispenser.
