Every LT700P replacement we checked
"Certified for" comes from the certifier's own listing, not from the box or the Amazon page. Per filter = the pack price divided by the filters in the pack. Per year = 2 filters, because the filter is changed every 6 months.

Which LG filter do I have?
LT700P, LT700PC, LT700PCS and ADQ36006101 are the same LG filter. LT700P2 and LT700P3 are 2- and 3-packs of it. Retailers also sell it as Kenmore 9690 or 469690. The part number is printed on the old filter and in your fridge manual.
LG's LT800P and LT1000P are different filters. Do not swap them in. LG's own LT800P is on NSF's list for lead; the LT700P is not.
What NSF lists for LG
NSF's list for LG Electronics has three LG fridge filters: the LT500P (500 gallons, taste and odor), the LT600P (300 gallons, lead and cysts) and the LT800P (200 gallons, lead and cysts). The LT700P is not there. LG's Amazon page for the LT700P says "NSF42 and NSF53", but NSF's own list does not back that up.
The copies are different. NSF lists the ICEPURE RWF1200AH (maker: Top Pure) and the PUREPLUS PP-RWF1200AH (maker: Aquazon) for lead, cysts and mercury at 200 gallons. Some brands sell a taste-and-odor version and a lead version that look the same, such as Waterdrop WD-F32 and Waterdrop Plus WDP-F32. Check the code on the listing.
Common questions
Is the LG LT700P NSF certified?
We could not find a listing. NSF's list for LG Electronics (read November 2, 2026) has the LT500P, LT600P and LT800P, not the LT700P, and IAPMO R&T has no LG listing. LG's Amazon page says NSF 42 and 53, but no certifier shows it for this filter.
Is Kenmore 9690 the same as the LG LT700P?
Retailers and copy makers list Kenmore 9690 (also sold as 469690) as the same filter as the LT700P. Kenmore's own number is not on NSF. The copies on this page name LT700P and ADQ36006101 in their listings.
Is a certified copy as good as the LG filter?
For lead and cysts it is better documented: NSF lists the ICEPURE RWF1200AH and the PUREPLUS PP-RWF1200AH for lead, cysts and mercury, and we found no listing for LG's own LT700P.
Is the Waterdrop WD-F32 certified for lead?
No. NSF lists WD-F32 for chlorine, taste and odor only. Waterdrop Plus WDP-F32 is listed for lead, but the Amazon listing we found names LG's code instead of WDP-F32, so we can not tie it to the listing.
How often should I change it?
LG rates the LT700P for 6 months or 200 gallons, whichever comes first. That is 2 filters a year.
My fridge takes the LT800P or LT1000P. Does this apply?
No. Those are different filters. See LT800P vs LT1000P.
