About This

• 💧 REPLACES LG LT600P AND 5231JA2006A: the twist-in cartridge LG sells as LT600P is the same part sold as 5231JA2006A, 5231JA2006B, LT600. Fridges that take it include LRSC26910TT, LSC27910ST, LFX25960ST, LFX21975ST and the rest of the LG side-by-side and French-door fridges with the cartridge behind the base grille. Check the code on the cartridge you are removing against this list before you order. Full model list in the description below.
• 💧 NSF 42 AND NSF 372 CERTIFIED BY IAPMO R&T: third-party lab tested and certified to NSF/ANSI 42 for chlorine, taste and odor reduction and to NSF/ANSI 372 for lead-free materials (under 0.25% lead). The housing is BPA-free, food-grade plastic; the block is 0.5 micron coconut-shell carbon. Both standards are on the IAPMO register under R-9990, which many two-packs for this fridge cannot say. The R-9990 certificate is on the box and on the register, which is where a claim becomes a fact.
• 💧 CLEANER WATER WITHOUT THE LG PRICE: a denser coconut-shell carbon block removes up to 97% of chlorine, odor and bad taste, traps rust, sand and scale down to 0.5 micron and keeps calcium, magnesium and potassium in the water. That is what the R-9990 puts in every glass from an LG door. Flow to the dispenser and ice maker stays steady. Pay less than the brand for the same fit, or get more carbon and a certificate than the uncertified filters. Why pay more?
• 💧 A FULL YEAR IN ONE BOX: each cartridge is rated for six months or 300 gallons, whichever comes first, so this pair carries an LG fridge through a full year of dispenser water and ice. The second filter stays sealed in its bag until the change-filter light comes back on. If the flow slows or the taste changes earlier, the block is full; swap it and start the next six months. Every R-9990 box carries an install-date label for the next change.
• 💧 TWO-MINUTE SWAP, NO TOOLS: the cartridge sits behind the base grille at the bottom of the fridge. Twist the old one a quarter turn to release it, pull it straight out, push the new one in and twist it until it stops, then reset the filter light. Then run the dispenser about three minutes (three to four gallons) and discard that water; a cloudy first glass is harmless carbon dust. Cold water lines only. Every R-9990 fits the same way.
• 💧 REFRESH, US-BASED SINCE 2016: we have made replacement refrigerator filters since 2016, from a US-based company with US-based support. Every R-9990 is built to the exact dimensions and seal of the cartridge it replaces, so it seats and flows like the one you are taking out, is quality-checked before it ships, and is tested by an independent lab and certified by IAPMO R&T. Cleaner water without the brand price. Why pay more?
