Yes, it’s okay to use a generic (third-party) water filter in an LG refrigerator like model LTWS24223S as long as the filter is specifically listed as compatible with your exact model and installs without forcing. A poor fit can cause leaks, low water flow, or reduced filtration performance.

What we recommend for LTWS24223S

• Match the filter to the refrigerator model number (LTWS24223S), not just the brand.
• Choose a filter that lists NSF/ANSI certifications appropriate for drinking water filtration.
• Replace the filter on schedule (most households do it about every 6 months, sooner with heavy use).
• After installing, flush several gallons of water to clear carbon fines and air.
• If you notice dripping, remove the filter and reinstall it; confirm it locks in fully.

If you want the model-matched OEM option, the listed filter for this refrigerator is LG lt500p refrigerator water filter ADQ72910911.

Generic vs OEM filters: quick comparison

Feature	OEM (model-matched)	Generic/compatible
Fit and seal	Consistent	Varies by brand and batch
Filtration claims	Clear and consistent	Must verify certifications
Risk of leaks/flow issues	Lower	Higher if not truly compatible
Cost	Usually higher	Often lower

Troubleshooting after installing a generic filter

• Slow dispenser flow: confirm the filter is fully seated; flush more water; check for a kinked supply line.
• Bad taste/odor: flush additional water; replace if the filter is old or improperly stored.
• Leaks at the filter head: remove and reinstall; inspect the filter O-rings for damage; do not overtighten.

Why it matters

Your refrigerator water filter affects taste, odor, and sediment reduction, but it also has to seal correctly. On LTWS24223S, a filter that does not lock in cleanly can introduce air, reduce ice maker fill, or cause water to drip inside the fresh food compartment.

For step-by-step guidance, use how to replace the water filter in an LG refrigerator and your LTWS24223S owner’s manual.

Yes. For the LG LTWS24223S top-mount refrigerator, replacing the water filter on schedule keeps water tasting clean and helps maintain normal dispenser and ice maker flow. Most households replace the filter about every 6 months, or sooner if water flow slows or taste and odor change.

When you should replace the filter

• Every 6 months for typical use
• Sooner if the dispenser flow rate drops
• If ice cubes get smaller or production slows
• If water tastes or smells different
• After plumbing work, a boil-water advisory, or long periods without use

For model-specific filter location and reset steps, follow the LTWS24223S owner's manual.

The correct filter for this model

This model uses an LG LT500P-style water filter. On Sears PartsDirect, the matching part is:

• LG lt500p refrigerator water filter ADQ72910911 (part number 5231JA2002A)

Quick comparison

If you notice	What it usually means	What to do
Slow water dispensing	Filter media is clogged with sediment	Replace the filter, then flush water
Odd taste or odor	Filter is exhausted or water quality changed	Replace the filter
Cloudy water after change	Air in the line or carbon fines	Flush several gallons
Ice maker issues	Restricted water supply through filter	Replace filter; check supply valve

Why it matters

A water filter is a wear item. As it loads up with sediment and contaminants, it can restrict water flow and reduce filtration performance. Staying on a regular replacement schedule helps protect water quality and prevents nuisance issues like slow dispensing and weak ice production.

After you replace it: do these steps

• Install the new filter fully seated and locked
• Dispense and discard several gallons of water to flush the system
• Dump the first bin or two of ice
• Reset the filter indicator (if your model has one) using the steps in the manual
